Summary: WELD-001318 AmbiguousResolutionException with Converter having
subclass
Key: SEAMFACES-242
URL: https://issues.jboss.org/browse/SEAMFACES-242
Project: Seam Faces
Issue Type: Bug
Components: CDI Integration, Validation & Conversion
Affects Versions: 3.1.0.Final
Environment: GF 3.1.2 with JDK 1.6.0b29 + SeamFaces 3.1.0 + RichFaces 4.2.0
Reporter: Fab Mars
On some page I have <rich:inputNumberSpinner label="Count"
value="#{orderLine.quantity}"
converter="IntegerOrNullConverter".../>
The converter to use is explicit. But I also extended that converter class twice for other
purposes.
When accessing the page I get a WELD-001318 ambiguous dependency. Stacktrace below.
SeamApplicationWrapper#createConverter ends up calling BeanManagerUtils#isDependentScoped
which tries to CDI-resolve the the converter type. Naturally weld finds the 3 converters
(the one I asked for and the 2 subclasses) and it complains as it should. I strongly
believe calling BM#resolve here is wrong.
The same will happen with SeamApplicationWrapper#createValidator.
1) These methods should deal with only the actual requested type
2) The use of BeanManagerUtils.getContextualInstance in
SeamApplicationWrapper.attemptExtension will also lead to problems.
3) More generally, I BeanManagerUtils.isDependentScoped isn't selective enough either
Instead of #resolve, another utility method like this may be called:
public <T> Set<Bean<?>> getExactBeanForType(final Class<T>
type) {
Set<Bean<?>> beans = manager.getBeans(type);
for(Bean<?> bean : beans) {
if(type.equals(bean.getBeanClass())) {
return Collections.<Bean<?>>singleton(bean);
}
}
return Collections.<Bean<?>>emptySet();
}

WELD-001318 AmbiguousResolutionException with Converter having
subclass
-----------------------------------------------------------------------
Key: SEAMFACES-242
URL: https://issues.jboss.org/browse/SEAMFACES-242
Project: Seam Faces
Issue Type: Bug
Components: CDI Integration, Validation & Conversion
Affects Versions: 3.1.0.Final
Environment: GF 3.1.2 with JDK 1.6.0b29 + SeamFaces 3.1.0 + RichFaces 4.2.0
Reporter: Fab Mars
On some page I have <rich:inputNumberSpinner label="Count"
value="#{orderLine.quantity}"
converter="IntegerOrNullConverter".../>
The converter to use is explicit. But I also extended that converter class twice for
other purposes.
When accessing the page I get a WELD-001318 ambiguous dependency. Stacktrace below.
SeamApplicationWrapper#createConverter ends up calling BeanManagerUtils#isDependentScoped
which tries to CDI-resolve the the converter type. Naturally weld finds the 3 converters
(the one I asked for and the 2 subclasses) and it complains as it should. I strongly
believe calling BM#resolve here is wrong.
The same will happen with SeamApplicationWrapper#createValidator.
1) These methods should deal with only the actual requested type
2) The use of BeanManagerUtils.getContextualInstance in
SeamApplicationWrapper.attemptExtension will also lead to problems.
3) More generally, I BeanManagerUtils.isDependentScoped isn't selective enough
either
Instead of #resolve, another utility method like this may be called:
{code}
public <T> Set<Bean<?>> getExactBeanForType(final Class<T>
type) {
Set<Bean<?>> beans = manager.getBeans(type);
for(Bean<?> bean : beans) {
if(type.equals(bean.getBeanClass())) {
return Collections.<Bean<?>>singleton(bean);
}
}
return Collections.<Bean<?>>emptySet();
}
{code}
Stacktrace of the issue:

jbossbot jira [SEAMFACES-242] WELD-001318 AmbiguousResolutionException with Converter
having subclass [Open (Unresolved) Bug, Major, Unassigned]
https://issues.jboss.org/browse/SEAMFACES-242
{color:red}lightguard_jp{color} Right.
{color:blue}bleathem{color} why does a bean lookup of a base class result in being
ambiguous with the classes that extend it?
{color:red}lightguard_jp{color} I haven't looked at the code at all, but based on what
he's seeing, how does this even work?
{color:blue}bleathem{color} If I lookup A
{color:blue}bleathem{color} and B extedns A
{color:red}lightguard_jp{color} Or is it only when there's a subclass involved
{color:blue}bleathem{color} why is B ambiguous with A?
{color:blue}bleathem{color} right
{color:blue}bleathem{color} this issue has to do with subclassing
{color:red}lightguard_jp{color} Because there are two of them
{color:red}lightguard_jp{color} A is an A and B is also an A
{color:blue}bleathem{color} so how can I lookup A?
{color:blue}bleathem{color} if I want A?
{color:blue}bleathem{color} if I wanted B, I'd lookup B
{color:red}lightguard_jp{color} A qualifier, B could also @Specialize
{color:blue}bleathem{color} hmm
{color:red}lightguard_jp{color} A could be an abstract class
{color:red}lightguard_jp{color} Well, then you'd get B anyway.
{color:red}lightguard_jp{color} If both A and B are concrete classes
{color:blue}bleathem{color} @Quliafirers won't work so well in the facelet scenario
{color:red}lightguard_jp{color} You have to use @Specializes or a qualifier
{color:blue}bleathem{color} so is there no resolution to be found here?
{color:red}lightguard_jp{color} Why would you subclass a validator or a converter?
{color:red}lightguard_jp{color} Wouldn't composition work better?
{color:red}lightguard_jp{color} hm
{color:red}lightguard_jp{color} Even if we return a set of beans that would work, how do
we select the correct one?
{color:red}lightguard_jp{color} What's to say we'll actually get a subclass from
JSF? What if it passes us the super class and what the developer is expecting is a
subclass?
{color:red}lightguard_jp{color} All we get is a converterId (which would work) or a target
class, which any of the subclasses should be able to handle
{color:red}lightguard_jp{color} It really seems like supporting inheritance here is going
to be extremely difficult.
{color:red}lightguard_jp{color} If it's even possible
{color:red}lightguard_jp{color} {color:blue}bleathem{color}: thoughts?
{color:blue}bleathem{color} {color:red}lightguard_jp{color}: that's a good summary of
the problems we'd face in trying to support this use case
{color:blue}bleathem{color} I agree - composition would work better here

WELD-001318 AmbiguousResolutionException with Converter having
subclass
-----------------------------------------------------------------------
Key: SEAMFACES-242
URL: https://issues.jboss.org/browse/SEAMFACES-242
Project: Seam Faces
Issue Type: Bug
Components: CDI Integration, Validation & Conversion
Affects Versions: 3.1.0.Final
Environment: GF 3.1.2 with JDK 1.6.0b29 + SeamFaces 3.1.0 + RichFaces 4.2.0
Reporter: Fab Mars
On some page I have <rich:inputNumberSpinner label="Count"
value="#{orderLine.quantity}"
converter="IntegerOrNullConverter".../>
The converter to use is explicit. But I also extended that converter class twice for
other purposes.
When accessing the page I get a WELD-001318 ambiguous dependency. Stacktrace below.
SeamApplicationWrapper#createConverter ends up calling BeanManagerUtils#isDependentScoped
which tries to CDI-resolve the the converter type. Naturally weld finds the 3 converters
(the one I asked for and the 2 subclasses) and it complains as it should. I strongly
believe calling BM#resolve here is wrong.
The same will happen with SeamApplicationWrapper#createValidator.
1) These methods should deal with only the actual requested type
2) The use of BeanManagerUtils.getContextualInstance in
SeamApplicationWrapper.attemptExtension will also lead to problems.
3) More generally, I BeanManagerUtils.isDependentScoped isn't selective enough
either
Instead of #resolve, another utility method like this may be called:
{code}
public <T> Set<Bean<?>> getExactBeanForType(final Class<T>
type) {
Set<Bean<?>> beans = manager.getBeans(type);
for(Bean<?> bean : beans) {
if(type.equals(bean.getBeanClass())) {
return Collections.<Bean<?>>singleton(bean);
}
}
return Collections.<Bean<?>>emptySet();
}

Fab Mars commented on SEAMFACES-242:
------------------------------------
Seriously? Steering to avoid a rock on the road doesn't make the rock disappear.
See the javadoc of Application#createConverter: "Instantiate and return a new
Converter instance of *the class* specified by a previous call to addConverter() for the
*specified* converter id."
Here is what I have in my faces config.
<converter>
<converter-id>IntegerOrNullConverter</converter-id>
<converter-class>org.mars.toolkit.jsf.converter.IntegerOrNullConverter</converter-class>
</converter>
I've declared *explicitly*, *exactly*, *THE class* I want to use when I point at a
given converterId. FQCN, no less. Who cares about CDI's resolve mechanism just there?
So not only is it illogic to have an Application(Wrapper) that does something different
than if seam-faces wasn't here, but it is also pointless to try to "support"
anything extra. Just get THE instance matching exactly the FQCN, use it, that's all a
user wants! CDI is a mean here, not a finality.
Please be serious and reopen, I'll be glad to submit a pull req.

Jason Porter commented on SEAMFACES-242:
----------------------------------------
Submit a patch / pull request and we'll take a look.
Part of the problem is not when you've explicitly declared the converter, but when
you're using a class. Any one of the subclasses should work as the proper converter.
In that case we may not be able to properly guess which one is meant to be used.
WELD-001318 AmbiguousResolutionException with Converter having
subclass
-----------------------------------------------------------------------
Key: SEAMFACES-242
URL: https://issues.jboss.org/browse/SEAMFACES-242
Project: Seam Faces
Issue Type: Bug
Components: CDI Integration, Validation & Conversion
Affects Versions: 3.1.0.Final
Environment: GF 3.1.2 with JDK 1.6.0b29 + SeamFaces 3.1.0 + RichFaces 4.2.0
Reporter: Fab Mars
On some page I have <rich:inputNumberSpinner label="Count"
value="#{orderLine.quantity}"
converter="IntegerOrNullConverter".../>
The converter to use is explicit. But I also extended that converter class twice for
other purposes.
When accessing the page I get a WELD-001318 ambiguous dependency. Stacktrace below.
SeamApplicationWrapper#createConverter ends up calling BeanManagerUtils#isDependentScoped
which tries to CDI-resolve the the converter type. Naturally weld finds the 3 converters
(the one I asked for and the 2 subclasses) and it complains as it should. I strongly
believe calling BM#resolve here is wrong.
The same will happen with SeamApplicationWrapper#createValidator.
1) These methods should deal with only the actual requested type
2) The use of BeanManagerUtils.getContextualInstance in
SeamApplicationWrapper.attemptExtension will also lead to problems.
3) More generally, I BeanManagerUtils.isDependentScoped isn't selective enough
either
Instead of #resolve, another utility method like this may be called:
{code}
public <T> Set<Bean<?>> getExactBeanForType(final Class<T>
type) {
Set<Bean<?>> beans = manager.getBeans(type);

WELD-001318 AmbiguousResolutionException with Converter having
subclass
-----------------------------------------------------------------------
Key: SEAMFACES-242
URL: https://issues.jboss.org/browse/SEAMFACES-242
Project: Seam Faces
Issue Type: Bug
Components: CDI Integration, Validation & Conversion
Affects Versions: 3.1.0.Final
Environment: GF 3.1.2 with JDK 1.6.0b29 + SeamFaces 3.1.0 + RichFaces 4.2.0
Reporter: Fab Mars
On some page I have <rich:inputNumberSpinner label="Count"
value="#{orderLine.quantity}"
converter="IntegerOrNullConverter".../>
The converter to use is explicit. But I also extended that converter class twice for
other purposes.
When accessing the page I get a WELD-001318 ambiguous dependency. Stacktrace below.
SeamApplicationWrapper#createConverter ends up calling BeanManagerUtils#isDependentScoped
which tries to CDI-resolve the the converter type. Naturally weld finds the 3 converters
(the one I asked for and the 2 subclasses) and it complains as it should. I strongly
believe calling BM#resolve here is wrong.
The same will happen with SeamApplicationWrapper#createValidator.
1) These methods should deal with only the actual requested type
2) The use of BeanManagerUtils.getContextualInstance in
SeamApplicationWrapper.attemptExtension will also lead to problems.
3) More generally, I BeanManagerUtils.isDependentScoped isn't selective enough
either
Instead of #resolve, another utility method like this may be called:
{code}
public <T> Set<Bean<?>> getExactBeanForType(final Class<T>
type) {
Set<Bean<?>> beans = manager.getBeans(type);
for(Bean<?> bean : beans) {
if(type.equals(bean.getBeanClass())) {
return Collections.<Bean<?>>singleton(bean);
}
}
return Collections.<Bean<?>>emptySet();
}
{code}

-------------------------------------------------------------
You'll have it very soon.
Yes you can since the JSF Application(wrapper) retrieves Converter/Validators matching
*exactly* the specified FQCN. Not "anything that is assignable to the FQCN".
By the way, the code ends up calling this method. The javadoc is (mostly) right, the code
doesn't match.
I'll check the impacts, etc.
{code}
/**
* Get a single CDI managed instance of a specific class. Return only the first result
if multiple beans are available.
* [...]
*/
public static <T> T getContextualInstance(final BeanManager manager, final
Class<T> type) {
T result = null;
Bean<T> bean = (Bean<T>) manager.resolve(manager.getBeans(type));
if (bean != null) {
CreationalContext<T> context = manager.createCreationalContext(bean);
if (context != null) {
result = (T) manager.getReference(bean, type, context);
}
}
return result;
}

WELD-001318 AmbiguousResolutionException with Converter having
subclass
-----------------------------------------------------------------------
Key: SEAMFACES-242
URL: https://issues.jboss.org/browse/SEAMFACES-242
Project: Seam Faces
Issue Type: Bug
Components: CDI Integration, Validation & Conversion
Affects Versions: 3.1.0.Final
Environment: GF 3.1.2 with JDK 1.6.0b29 + SeamFaces 3.1.0 + RichFaces 4.2.0
Reporter: Fab Mars
On some page I have <rich:inputNumberSpinner label="Count"
value="#{orderLine.quantity}"
converter="IntegerOrNullConverter".../>
The converter to use is explicit. But I also extended that converter class twice for
other purposes.
When accessing the page I get a WELD-001318 ambiguous dependency. Stacktrace below.
SeamApplicationWrapper#createConverter ends up calling BeanManagerUtils#isDependentScoped
which tries to CDI-resolve the the converter type. Naturally weld finds the 3 converters
(the one I asked for and the 2 subclasses) and it complains as it should. I strongly
believe calling BM#resolve here is wrong.
The same will happen with SeamApplicationWrapper#createValidator.
1) These methods should deal with only the actual requested type
2) The use of BeanManagerUtils.getContextualInstance in
SeamApplicationWrapper.attemptExtension will also lead to problems.
3) More generally, I BeanManagerUtils.isDependentScoped isn't selective enough
either
Instead of #resolve, another utility method like this may be called:
{code}
public <T> Set<Bean<?>> getExactBeanForType(final Class<T>
type) {
Set<Bean<?>> beans = manager.getBeans(type);
for(Bean<?> bean : beans) {
if(type.equals(bean.getBeanClass())) {
return Collections.<Bean<?>>singleton(bean);
}
}
return Collections.<Bean<?>>emptySet();
}
{code}
Stacktrace of the issue:

WELD-001318 AmbiguousResolutionException with Converter having
subclass
-----------------------------------------------------------------------
Key: SEAMFACES-242
URL: https://issues.jboss.org/browse/SEAMFACES-242
Project: Seam Faces
Issue Type: Bug
Components: CDI Integration, Validation & Conversion
Affects Versions: 3.1.0.Final
Environment: GF 3.1.2 with JDK 1.6.0b29 + SeamFaces 3.1.0 + RichFaces 4.2.0
Reporter: Fab Mars
On some page I have <rich:inputNumberSpinner label="Count"
value="#{orderLine.quantity}"
converter="IntegerOrNullConverter".../>
The converter to use is explicit. But I also extended that converter class twice for
other purposes.
When accessing the page I get a WELD-001318 ambiguous dependency. Stacktrace below.
SeamApplicationWrapper#createConverter ends up calling BeanManagerUtils#isDependentScoped
which tries to CDI-resolve the the converter type. Naturally weld finds the 3 converters
(the one I asked for and the 2 subclasses) and it complains as it should. I strongly
believe calling BM#resolve here is wrong.
The same will happen with SeamApplicationWrapper#createValidator.
1) These methods should deal with only the actual requested type
2) The use of BeanManagerUtils.getContextualInstance in
SeamApplicationWrapper.attemptExtension will also lead to problems.
3) More generally, I BeanManagerUtils.isDependentScoped isn't selective enough
either
Instead of #resolve, another utility method like this may be called:
{code}
public <T> Set<Bean<?>> getExactBeanForType(final Class<T>
type) {
Set<Bean<?>> beans = manager.getBeans(type);
for(Bean<?> bean : beans) {
if(type.equals(bean.getBeanClass())) {
return Collections.<Bean<?>>singleton(bean);
}
}
return Collections.<Bean<?>>emptySet();
}
{code}
Stacktrace of the issue:
