ability to create history entry for variables --------------------------------------------- Key: JBPM-2506 URL: https://jira.jboss.org/jira/browse/JBPM-2506 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: jBPM 4.0 Reporter: Hauke Rabe ScopeInstanceImpl#createVariableObject has the ability to enable history. But there is only a setVariable method wich disables the history. So, add the history flag to user interfaces. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1164) Null Pointer Exception is thrown when subprocess is leave event is fired.

by Gurpreet Sahota (JIRA)

Null Pointer Exception is thrown when subprocess is leave event is fired. ------------------------------------------------------------------------- Key: JBPM-1164 URL: http://jira.jboss.com/jira/browse/JBPM-1164 Project: JBoss jBPM Issue Type: Bug Affects Versions: jBPM jPDL 3.2.2 Environment: Windows XP Pro, Sun JDK 1.5.0_13 Reporter: Gurpreet Sahota Assigned To: Tom Baeyens I have a process flow where process (A) calls a process state that in turn calls subprocess (B). When Subprocess "end" state is signalled then I receive a Null Pointer Exception. Following is stack trace java.lang.NullPointerException at org.jbpm.graph.node.ProcessState.leave(ProcessState.java:204) at org.jbpm.graph.exe.Token.signal(Token.java:195) at org.jbpm.graph.exe.Token.signal(Token.java:140) When debugging, it turns out that "leave" method in ProcessState tries to retrieve subProcessInstance from execution context. This is set to null causing exception. If executionContext.getToken() is used to retrieve the subProcessInstance, then it is not null. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2622) fix java static factory method use case

by Tom Baeyens (JIRA)

fix java static factory method use case ---------------------------------------- Key: JBPM-2622 URL: https://jira.jboss.org/jira/browse/JBPM-2622 Project: jBPM Issue Type: Task Security Level: Public (Everyone can see) Reporter: Tom Baeyens Assignee: Tom Baeyens Fix For: jBPM 4.3 this doesn't work as expected. <process name="OrderWithRules"> <start> <transition to="isImportant"> <java var="amount" class="java.lang.Integer" method="parseInt"> <arg><object expr="#{amount}" /></arg> </java> </transition> </start> cause is to be found somewhere in JavaBinding, i think if (XmlUtil.attribute(element, "method", true, parse, null)!=null) { UserCodeReference invocationReference = parser.parseUserCodeReference(element, parse); javaActivity.setInvocationReference(invocationReference); ObjectDescriptor objectDescriptor = (ObjectDescriptor) invocationReference.getDescriptor(); javaActivity.setArgDescriptors(objectDescriptor.getArgDescriptors()); objectDescriptor.setArgDescriptors(null); javaActivity.setMethodName(objectDescriptor.getMethodName()); objectDescriptor.setMethodName(null); } by setting the methodName to null in the object descriptor (objectDescriptor.setMethodName(null)), the object descriptor will not see it as a static factory method, but instead will look for the constructor of the class. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2821) Adding a variable converter to jBPM is not intuitive and the documentation is lacking.

by Jochen Mader (JIRA)

Adding a variable converter to jBPM is not intuitive and the documentation is lacking. -------------------------------------------------------------------------------------- Key: JBPM-2821 URL: https://jira.jboss.org/jira/browse/JBPM-2821 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.3 Reporter: Jochen Mader To add a converter to jBPM it's currently required to add it in two places: jbpm.variables.types.xml and jbpm.execution.hbm.xml There are two issues with this: 1) I don't think it's a good approach to be required to edit two files to get the converter enabled. 2) The second file is an internal hibernate mapping file for jBPM and shouldn't be edited by a user for something as simple as adding a converter. At the very least the whole thing should be added to the documentation. Even better would be to enable converters by just adding them to jbpm.variables.types.xml -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2809) Defer email sending until transaction is commited

by Peter Horvath (JIRA)

Defer email sending until transaction is commited ------------------------------------------------- Key: JBPM-2809 URL: https://jira.jboss.org/jira/browse/JBPM-2809 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: jBPM 4.x Reporter: Peter Horvath Currently emails are sent immediately when they are dispatched from e.g. a mail node or task notification. This can be confusing since the transaction the JBPM execution runs in can be rolled back later. For example a workflow could contain an initial email node which sends a confirmation email to the user who submitted a request ("Your request has been successfully submitted to the workflow system...") - but if the the next node in the workflow throws an exception which rolls back the transaction the submitted request won't be stored in the system. This can be very confusing for the end users. There are similar problems with task notifications as well. I think it would be fairly easy to solve this problem by introducing an optional attribute to the mail node which instructs JBPM to send the email only on transaction commit and modify MailActivity so that it creates a transaction synchronization which sends the email from javax.transaction.Synchronization.afterCompletion(int status) method if the status is COMMITED. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2798) ID Generation for Oracle or DB2 Database when using out of the box JobExecutor causes Integrity Constraint violations with subprocesses

by Martin Porter (JIRA)

ID Generation for Oracle or DB2 Database when using out of the box JobExecutor causes Integrity Constraint violations with subprocesses --------------------------------------------------------------------------------------------------------------------------------------- Key: JBPM-2798 URL: https://jira.jboss.org/jira/browse/JBPM-2798 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.3 Environment: WLS 11g, Oracle 11g, jBPM 4.3 Reporter: Martin Porter When using jBPM in default configuration with out of the box JobExecutors (2 threads) we see issues with ID generation causing Integrity Constraint violations. There is a long thread related to this as also this behaviour has been seen with DB2 as well as Oracle. The link to the thread is:- http://community.jboss.org/message/522625#522625 This seems to be related to the use of Subprocesses. It has been witnessed that removing the subprocesses solves the issue. Unfortunately we cannot do that. We solved the issue by implementing our own ID generator using an Oracle Sequence. I have attached the code to this case. It would be nice to have this added to the trunk code if possible. We have been testing with it and it solved all of our problems. Note that this was NOT running in cluster configuration and the problems occur on a single server instance with the default (non modifed) JobExecutor configuration.

[JBoss JIRA] Created: (JBPM-2789) Java task field injection works when java class is on the Spring context

by Robert Moskal (JIRA)

Java task field injection works when java class is on the Spring context ------------------------------------------------------------------------ Key: JBPM-2789 URL: https://jira.jboss.org/jira/browse/JBPM-2789 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.1 Environment: Nothing unusual, hsql, jetty. Reporter: Robert Moskal If I create a java task that pulls from the spring context, like so: <java expr="#{pipelineNode}" g="300,79,92,52" method="execute" name="Rig"> <field name="execution"><object expr="#{execution}"/></field> <field name="allowableFlows"><string value="NormalFlow2"/></field> <transition g="-31,-28" name="success" to="Animate"/> <transition g="303,252:-25,-32" name="to Rework" to="Rework"/> </java> Then none of the field injectors work. However if I change the definition to one where I instantiate using the class: <java class="com.bluesky.skyline.workflow.extensions.PipelineNode" g="123,78,127,52" method="execute" name="Model">  <field name="allowableFlows"><string value="NormalFlow2"/></field> <transition g="-31,-28" name="success" to="Rig"/> <transition g="-24,-58" name="to Rework" to="Rework"/> </java> Then they work as expected. Whats' interesting is that in the latter case the Execution isn't injected.However, if I add the execution in an argument to my method: <arg><object expr="#{execution}"/></arg> Then it is passed in correctly. I suspect this has to do with the way the java code is stored with the process. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2783) refresh button doesn't wok in gwt-console application

by sunil tiwari (JIRA)

refresh button doesn't wok in gwt-console application ----------------------------------------------------- Key: JBPM-2783 URL: https://jira.jboss.org/jira/browse/JBPM-2783 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Console Affects Versions: jBPM 4.2 Environment: RAD7.5 , websphere server 6.1 , derby Data base , hibernate for DB connection Reporter: sunil tiwari I imported the gwt-console.war and gwt-console-server.war as web project in RAD 7.5 . Now i ran the console application after login i can see the process definitions list in the process grid , if i add another process instance using db explorer as i have an application which creates process instances and click on refresh button ideally that instance should come into the list but nothing happens . Even if select one instance and terminate it or delete it i m able to see them in the list after click on refresh button . -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2768) Provide API for accessing JBPM email infrastructure

by Peter Horvath (JIRA)

Provide API for accessing JBPM email infrastructure --------------------------------------------------- Key: JBPM-2768 URL: https://jira.jboss.org/jira/browse/JBPM-2768 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: jBPM 4.x Reporter: Peter Horvath Currently there is no way to access JBPM email infrastructure from custom Java code (for example from an EventListener, or ActivityBehaviour) It would be good to be able to access JBPM email subsystem through a public API. Adding a new Facade class with a single method that allows you to select the email template and pass an org.jbpm.api.Execution should be quite easy to implement and would add a lot of power to EventListeners, etc. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
