Hi,
This is in relation to drools 4.0.4
I have an interesting problem. I am getting a null pointer exception when I am inserting a
fact into a StatefulSession object. What is odd about this NPE is that, as far as I can
tell (and I have inserted a breakpoint right before I insert the fact) that all the
properties in the object are initialized, and there are no rules accessing any thing that
could be null.
So here's my exception trace (just first few lines to get context):
Exception in thread "AWT-EventQueue-0" org.drools.RuntimeDroolsException:
java.lang.NullPointerException

Jason,
Can you please isolate and show us the rule that is creating the problem?
It is happening either in a eval() statement or in a nested property access.

New subject: Interesting null pointer exception when inserting a fact.
Hi Edson,
I'll do my best. The rule uses a DSL, so I will post the specific rule and then the
corresponding DSL file. I do believe it's happening inside the eval.
Rule:
rule "awe"
dialect "mvel"
ruleflow-group 'Validation'
when
A AReallyWonderfulAndCrappyTest entry has results where
BasicMountFridayTest mountType IsEqualTo "T"
then
set BasicBlindFridayTest_JP rightwidht to 44
end
DSL:
[condition][]A {TemplateName} entry has results where=$daObj : {TemplateName}()
[condition][]{field} IsEqualTo {value}=eval ( {field} == {value} )
[condition][]{field} LessThan {value}=eval ( {field} < {value} )
[condition][]{field} GreaterThan {value}=eval ( {field} > {value} )
[condition][]{field} LessThanOrrEqualTo {value}=eval ( {field} <= {value} )
[condition][]{field} GreaterThanOrrEqualTo {value}=eval ( {field} >= {value} )
[condition][]{field} NotEqualTo {value}=eval ( {field} != {value} )
[condition][]A {TemplateName} entry is valid=$daObj : {TemplateName}()
[consequence][]set {Field} {Member} to {Value}=$daObj.get{Field}().set{Member}({Value});
[consequence][]Log {value}=LOG.info({value});
[consequence][]set {GlobalVar} {Member} to {Value}={GlobalVar}.set{Member}({Value})
[consequence][]set {Field} {Member1} to global {GlobalVar}
{GlobalMember}=$daObj.get{Field}().set{Member}({GlobalVar}.get{GlobalMember}())
[*][]set global {GlobalVar} {Member1} to global {GlobalVar}
{Member2}={GlobalVar}.set{Member1}({GlobalVar}.get{Member2}())
[consequence][]show {field} {Member1}=$daObj.get{field}().set{Member1}Visible(true);
[consequence][]hide {field} {Member1}=$daObj.get{field}().set{Member1}Visible(false);
[consequence][]show table {field}=$daObj.set{field}Visible(true);
[consequence][]hide table {field}=$daObj.set{field}Visible(false);

We are about to release 4.0.5, next week. This has a large number of bug
fixes, especially multi-threading bugs. Anyone that has production
issues can you please do a checkout for the 4.0.x branch asap and
provide us with a test case if it is not fixed. If you don't get your
test case to us by end of monday, start of tuesday, you'll have to wait
another 2 months+ for 4.0.6.

New subject: Do you have a Bug?
I had reported an issue a couple of weeks ago with nested inner classes not
being handled correctly.
I made some changes to the org.drools.base.ClassTypeResolver class to
resolve it and everything appears to work fine.
How do I provide the fix and test case to you? Do you want me to raise a
JIRA?
Thanks,
Narendra

Yes you will need to raise a JIRA. At this stage we have no plans to fix
this, as we can consider inner inner classes esoteric enough to say it's
unsupported. Although if someone can provide a clean patch, it would be
nice to fix. You'll have to be quick though, if you want the fix in 4.0.5

Héron,
We are looking into the plugin build error. Meanwhile, please
update to maven 2.0.8. Unfortunately maven is having some problems to
build with different versions.
If it's got that far it means it's atleast
building the drools-core and
drools-compiler jars. That should be enough for you to test your problem.

I Had the same probleme with maven 2.0.8 (I used this before) and in the documentation, it

Héron,
We are looking into the plugin build error. Meanwhile, please update to
maven 2.0.8. Unfortunately maven is having some problems to build with
different versions.

New subject: Interesting null pointer exception when inserting afact.
I'm no expert but recall there can be problems running "long running"
(subjective) code from AWT's worker thread.
I thought it was good practice to run your "application code" in a worker
thread. This was the first google hit I had on the matter.

Can you please isolate and show us the rule that is creating the problem?
It is happening either in a eval() statement or in a nested property access.

Hi,
This is in relation to drools 4.0.4
I have an interesting problem. I am getting a null pointer exception when I
am inserting a fact into a StatefulSession object. What is odd about this
NPE is that, as far as I can tell (and I have inserted a breakpoint right
before I insert the fact) that all the properties in the object are
initialized, and there are no rules accessing any thing that could be null.
So here's my exception trace (just first few lines to get context):

I'm no expert but recall there can be problems running "long
running" (subjective) code from AWT's worker thread.
I thought it was good practice to run your "application code" in a
worker thread. This was the first google hit I had on the matter.

Jason,
Can you please isolate and show us the rule that is creating
the problem? It is happening either in a eval() statement or in a
nested property access.

Hi,
This is in relation to drools 4.0.4
I have an interesting problem. I am getting a null pointer
exception when I am inserting a fact into a StatefulSession
object. What is odd about this NPE is that, as far as I can
tell (and I have inserted a breakpoint right before I insert
the fact) that all the properties in the object are
initialized, and there are no rules accessing any thing that
could be null.
So here's my exception trace (just first few lines to get
context):
Exception in thread "AWT-EventQueue-0"

New subject: Interesting null pointer exception when inserting afact.
It looks like the bug is still in there.
I am attempting to resolve it myself, but in order to do so I need to go into the MVEL
code, but the mvel jar that is included as part of the drools classpath container (within
eclipse) is just mvel14.jar. So I'm not sure where the source is or what version of
MVEL source I should be attaching. I realize that the source-location thing is just an
Eclipse issue, but I thought I'd let you know right away that it looks like it's
still there.
Anywhere you can point me to that would help with making sure I'm looking the right
code.
Thanks,
Jason

New subject: Interesting null pointer exception when inserting afact.
Well, I've downloaded the source, and it appears that it is occuring in the
org.mvel.MVELRuntime class, method execute(). My equals token ("==") is being
properly recognized, and converted to its integer representation (10). However, in a block
with switch (operator), the org.mvel.Operator.EQUAL token does not appear, so the
execute() method returns a null value because nothing is ever evaluated.
I've even verified that null is being returned from the execute method.
I stepped back out to the line (in org.mvel.CompiledExpression,java)
return handleParserEgress(execute(false, this, staticContext, factory),
returnBigDecimal);
and then stepped into handleParserEgress and the first parameter, which is the return
value from execute() is null!
Any ideas?
Thanks,
Jason

(that setTemplate method is not a drools template)
Any ideas?
Thanks,

New subject: Interesting null pointer exception when insertingafact.
Not with Drools.
Happy for you to discount though; it was just an idea.

I can give this a shot, but the reason why you suggest this is not obvious
to me.
Have you encountered this problem yourself?

I'm no expert but recall there can be problems running "long running"
(subjective) code from AWT's worker thread.
I thought it was good practice to run your "application code" in a worker
thread. This was the first google hit I had on the matter.

Jason,
Can you please isolate and show us the rule that is creating the problem?
It is happening either in a eval() statement or in a nested property access.

Hi,
This is in relation to drools 4.0.4
I have an interesting problem. I am getting a null pointer exception when I
am inserting a fact into a StatefulSession object. What is odd about this
NPE is that, as far as I can tell (and I have inserted a breakpoint right
before I insert the fact) that all the properties in the object are
initialized, and there are no rules accessing any thing that could be null.
So here's my exception trace (just first few lines to get context):
Exception in thread "AWT-EventQueue-0" org.drools.RuntimeDroolsException:
