[ https://jira.jboss.org/jira/browse/JBPM-2703?page=com.atlassian.jira.plug... ] Maciej Swiderski updated JBPM-2703: ----------------------------------- Attachment: jbpm-2703-extended.patch Attaching patch that is a bit simplified if it comes to test case. Since it requires a class (compiled) one o deployment time but it must be excluded from class path when running the test, class is created and compiled on runtime. So no additional folders need to be created. Please let me know what do you think about the solution. If you apply only the patch for test case you could easily see that it will fail with change only to use context class loader. Patch file name: jbpm-2703-extended.patch

[ https://jira.jboss.org/jira/browse/JBPM-2703?page=com.atlassian.jira.plug... ] Huisheng Xu commented on JBPM-2703: ----------------------------------- Why not using ScopeInstanceImpl.getExecution() instead of Class Cast? change this if (scopeInstance instanceof ExecutionImpl) { ois = new DeploymentObjectInputStream(bais, ((ExecutionImpl) scopeInstance).getProcessDefinition().getDeploymentId()); } else { ois = new ObjectInputStream(bais); } to ois = new DeploymentObjectInputStream(bais, scopeInstance.getExecution().getProcessDefinition().getDeploymentId()); Now we needn't consider about task variable. So I think this patch is all right.

[ https://jira.jboss.org/jira/browse/JBPM-2703?page=com.atlassian.jira.plug... ] Maciej Swiderski commented on JBPM-2703: ---------------------------------------- Your patch does not include process definition resource so it won't work. Besides that it works fine. I know why I made it so complex - I simple looked at code of getExecution in ScopeInstanceImpl that returns null.... Change is very simple and yet so important so thanks for pointing it out. Will make an update and commit. I guess it is pretty straight forward and does not bring any side affects.
