[JBoss jBPM] - ContextInstance of a non-null ProcessInstance is null
by coolex
Hello!
I have this method which I call from a jboss rule:
public void dosth(org.jbpm.graph.exe.ProcessInstance processInstance){
| System.out.println("The Id of the process is: "+ processInstance.getId() );
| System.out.println("The value of the variabel is: "+ processInstance.getContextInstance().getVariable("owner") );
| }The result is:
| The Id of the process is: 1
| The value of the variabel is: null
I am 100% sure that I have set the process variable before with this code:org.jboss.seam.bpm.ProcessInstance.instance().getContextInstance().setVariable("owner", "testowner");
I made some other tests, so I know very well that this variable has been set perfectly.
The rule is also working without any problems.
But why I can't get the ContextInstance out of my non-null ProcessInstance?
bye

[JBoss jBPM] - Re: jBPM on GlassFish - HTTP status 500
by crued
The particular lines that seem to be causing trouble are the "gd:filter" tags. It seems that the entryVar is used in some EL expression inside the "test" and "filterArgument" attributes of this tag. My current guess is that Glassfish sees these and tries to evaluate them, but since the entryVar is not known to the EL context, it throws an exception.
So here's an example:
<gd:filter source="#{piList}" target="#{piList}" entryVar="entry" test="#{filter_ended and entry != null and entry.end != null or entry != null and entry.end == null and (filter_suspended and and entry.suspended or filter_running and ! and entry.suspended)}"/>
When Glassfish sees the #{ ... } it tries to evaluate it. It sees entry.end, and then tries to find the end property of the object "entry" in the current context. This doesn't exist --> BOOM.
I still don't know what to do to fix it...is entry supposed to exist at this point? Is the test being evaluated too soon? For now, I'll just disable the filter tags...

Thanks. I've read somewhere that all variables have to be initialized.
That's probably the cause of this error message. But I still have a problem

There's also something strange with the registration of the partner service.
When JBoss is started within Eclipse the wsdl of the partner service is registered
correctly. But when I start JBoss using run.bat the wsdl can't be retrieved
- the target namespace entry states "wsdl read failure".
