--------------------------------------------------------------
Hello All,
We have a quite complicated process definion with a lot of cases where a step has to be executed only on specific condition - something like the following diagram (see attached full example process definition JPDL file):
http://community.jboss.org/servlet/JiveServlet/showImage/4429/ForkJoinTes... http://community.jboss.org/servlet/JiveServlet/downloadImage/4429/450-189...
We used join nodes with *multiplicity="1"* setting to join the two possible outcome paths of the decision node:
*<join g="347,51,48,48" multiplicity="1" name="join1">
<transition g="424,76:-7,-17" name="to join2" to="join2"/>
</join>*
This approach used to work OK with JBPM 4.3 but it fails with version 4.4.
It seems that the handling of join nodes has been changed in this version: the first join node sets state to ended on the incoming execution which is not destroyed at that step but is delegated through to the outgoing transition, so the next join node (the last one before the end in the example) fails with the following exception:
Exception in thread "main" org.jbpm.api.JbpmException: execution[ForkJoinTest.10001.to script2.10002] is not active: ended

at org.jbpm.pvm.internal.svc.ExecutionServiceImpl.startProcessInstanceByKey(ExecutionServiceImpl.java:67)
For me, this seems to be a bug - clearly, the behaviour of JBPM has been changed between version 4.3 and 4.4. The attached process definition is executed correctly with JBPM 4.3.
What do you think about this?
Regards,
Peter

I use the jBpm4.4. install with spring,do like this:
I modify the build.xml file 187 line for create.cfg target.and change the tx to "spring",then ant create.cfg.I get the cfg files and copy all the files to example classpath.I Junit the *AsyncActivityTest.java.*
and get the error:

Hi Ales,
Thank you very much.

A.java snippet
public class A {
public void start() {
System.out.println(this.getClass()..getClassLoader());
// and print parent and ancestor classloader
System.out.println(new B());
}
}
When JBoss starts, NoClassDefFoundError is thrown out.
According to my understanding, two BaseClassLoader instances for a.beans and b.beans share a same class repository (DefaultDomain). If B is visible to A, then BaseClassLoader for a.beans can load class B.
The scenario contains servel steps:
1. BaseClassLoaders are registered to class repository (DefaultDomain)
2. BaseClassLoader for a.beans trys to load class B, and it trys from class repository, but it can't find.
3. Because BaseClassLoader for b.beans declares that it can load class B
4. Class repository delegates BaseClassLoader for b.beans to load class B
But this doesn't explain why NoClassDefFoundError happens.
Another question:
When is contextClassLoader of current thread set in JBoss5?
Regards,
Nesta
