seam:component intercept uses Seam standard rules by default
------------------------------------------------------------
Key: JBSEAM-1583
URL: http://jira.jboss.com/jira/browse/JBSEAM-1583
Project: JBoss Seam
Issue Type: Bug
Components: Spring
Affects Versions: 2.0.0.BETA1
Reporter: Magnus Heino
From spring-seam-2.0.xsd, intercept:
Determines whether Seam interceptors should be wrapped around a bean, by overriding
Seam's default rules.
Seldom do you want the seam interceptors wrapped around a sprig singleton. Auto will use
choose no
interception for a singleton and use Seam standard rules otherwise.
Looking at the code, I can't find anything about this "no interception for a
singleton" default.

If I change <seam:component/> to <seam:component intercept="false"/>
everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?

If I change <seam:component/> to <seam:component
intercept="false"/> everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?

Michael Youngstrom commented on JBSEAM-1583:
--------------------------------------------
1. Yes that documentation you quoted is wrong. I got rid of the "auto" feature
long ago. It now defaults to the seam default which is currently "true".
2. Seam uses Interceptors for a lot of functionality such as @Synchronized, @Asynchronous,
@In, @Out, etc.
3. I don't know why it's failing with intercept="true". :) I am using
it in the example and it works fine there. is there any more to that stacktrace?

From spring-seam-2.0.xsd, intercept:
Determines whether Seam interceptors should be wrapped around a bean, by overriding
Seam's default rules.
Seldom do you want the seam interceptors wrapped around a sprig singleton. Auto will use
choose no
interception for a singleton and use Seam standard rules otherwise.
Looking at the code, I can't find anything about this "no interception for a
singleton" default.

Magnus Heino commented on JBSEAM-1583:
--------------------------------------
No, nothing is missing from the stacktrace.
Found the problem, if intercept is true, my class needs to have a no arg constructor. It
did not have that since I was using constructor injection. What is the empty constructor
needed for here? You said that the seam bean and the spring bean was the same actual
instance... so the empty constructor bean is created for what reason? The bean when in use
is configured correct, so the constructor injected instance is the one being used...

If I change <seam:component/> to <seam:component
intercept="false"/> everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?

From spring-seam-2.0.xsd, intercept:
Determines whether Seam interceptors should be wrapped around a bean, by overriding
Seam's default rules.
Seldom do you want the seam interceptors wrapped around a sprig singleton. Auto will use
choose no
interception for a singleton and use Seam standard rules otherwise.
Looking at the code, I can't find anything about this "no interception for a
singleton" default.

Magnus Heino commented on JBSEAM-1583:
--------------------------------------
Ok, I guess this is the expected behaviour? seam:component creates seam components out of
something I have configured in spring. It is not optimal if you just want to access spring
things from seam, then its better to use
org.springframework.web.jsf.DelegatingVariableResolver instead. And that makes JBSEAM-1584
a nice thing to have once again...

[ http://jira.jboss.com/jira/browse/JBSEAM-1583?page=comments#action_12367474 ]
Michael Youngstrom commented on JBSEAM-1583:
--------------------------------------------
seam:component will use a spring instantiated bean as a Seam bean and wraps this spring
bean instance with the standard seam interceptors (if intercept==true). Seam uses a proxy
to achieve it's interceptor functionality. Seam components require a no-arg
constructor.
Looking at the Seam 2.0. code it appears some stuff has changed recently with regard to
how interception is done. Let me know if this functionality will work for you:
* <seam:component intercept="false"/> will make the spring bean a seam
component inject static variables such as @Logger and not try to create a seam proxy (no
need for no-arg constructor).
* <seam:component intercept="true"/> will make the spring bean a seam
component and create a seam proxy. @Logger will work but the spring bean will require a
no-arg constructor.
* <seam:component/> will use Seam's method of determining if interception is
needed or not (no interception if it is an entity bean or has the @BypassInterceptors on
the class).
Will that work for you and remove the need for JBSEAM-1584?

From spring-seam-2.0.xsd, intercept:
Determines whether Seam interceptors should be wrapped around a bean, by overriding
Seam's default rules.
Seldom do you want the seam interceptors wrapped around a sprig singleton. Auto will use
choose no
interception for a singleton and use Seam standard rules otherwise.
Looking at the code, I can't find anything about this "no interception for a
singleton" default.

If I change <seam:component/> to <seam:component
intercept="false"/> everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?

[ http://jira.jboss.com/jira/browse/JBSEAM-1583?page=all ]
Michael Youngstrom resolved JBSEAM-1583.
----------------------------------------
Fix Version/s: 2.0.0.CR1
Resolution: Done
Fixed documentation problem and fixed problem that might stop @Logger from working if
intercept="false".
You should now be able to use use @Logger in spring beans that are seam components.
Test it out and let me know if you have any trouble.

If I change <seam:component/> to <seam:component
intercept="false"/> everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?

Gaurav Saini commented on JBSEAM-1583:
--------------------------------------
I'm working on Spring-Seam hybrid application. I'm using Seam's @Logger
feature for logging in my application. It's working perfectly in Seam components and
Spring beans declared with <seam:component> tag, except the Spring beans from which
transaction is started.
I'm using spring declartive transaction feature using AOP. I'm using CGLIB proxies
instead of JDK dynamic proxies.
I have noticed that in my backing bean where I have injected that aop proxied beans, the
logger is available in that proxy. I have inspected the proxy to confirm this. But once
the control is moved to any method inside that proxied bean, the logger set to null.
Please help me out. I'm totally stuck and don't want to use Logger.getLog() at
all.

From spring-seam-2.0.xsd, intercept:

Seam's default rules.
Seldom do you want the seam interceptors wrapped around a sprig singleton. Auto will use
choose no
interception for a singleton and use Seam standard rules otherwise.
Looking at the code, I can't find anything about this "no interception for a

Yup, this looks like a true issue. As a work around you might be able to get away with
using @Logger on a static field. Though you may need to manually set the bean class in
your seam:component definition.

If I change <seam:component/> to <seam:component
intercept="false"/> everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?

Gaurav Saini commented on JBSEAM-1583:
--------------------------------------
Mike, I have already tried this option. The static field for @Logger works but not as per
my requirement. I have injected @Logger in one of my Base class. I need that whenever a
method of the base class is invoked the logger should be injected properly with correct
category.
This strategy works for all layers in my architecture except for the layer from which
transaction is started.
If i keep that field as static, then the logger is not updated after being set for once
initially on class loading.
Instead of workaround I would rather vote to reopen this issue to have a proper fix
provided in the coming releases.

--------------------------------------------
I've reopened the issue. Though Seam 2.x is currently in maintanence. I don't
have any time to produce a fix anytime soon. Feel free to provide a patch. The problem
is in Component's injection not unwrapping the spring proxy before injecting the
logger. This could be a tricky issue to fix since Component shouldn't have any Spring
specific code in it.

If I change <seam:component/> to <seam:component
intercept="false"/> everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?

seam:component intercept uses Seam standard rules by default

Issue Type: Bug

Assignee: Michael Youngstrom
Fix For: 2.0.0.CR1, The future
From spring-seam-2.0.xsd, intercept:
Determines whether Seam interceptors should be wrapped around a bean, by overriding
Seam's default rules.
Seldom do you want the seam interceptors wrapped around a sprig singleton. Auto will use
choose no
interception for a singleton and use Seam standard rules otherwise.
Looking at the code, I can't find anything about this "no interception for a
singleton" default.

If I change <seam:component/> to <seam:component
intercept="false"/> everything works.
1. Default for stateless spring beans seems to be true since seam standard rules are
applied if intercept is null, that is not defined. bug?
2. Why would I want to use intercept="true" anyway? What interceptors will be
added?
3. Why is it failing with intercept="true"?
