Yes, this is an issue because the OMG Semantic.xsd defines a specific sequence for the process element
<xsd:complexType name="tProcess">
<xsd:complexContent>
<xsd:extension base="tCallableElement">
<xsd:sequence>
<xsd:element ref="auditing" minOccurs="0" maxOccurs="1"/>
<xsd:element ref="monitoring" minOccurs="0" maxOccurs="1"/>
<xsd:element ref="property" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element ref="laneSet" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element ref="flowElement" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element ref="artifact" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element ref="resourceRole" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element ref="correlationSubscription" minOccurs="0" maxOccurs="unbounded"/>
<xsd:element name="supports" type="xsd:QName" minOccurs="0" maxOccurs="unbounded"/>
</xsd:sequence>
<xsd:attribute name="processType" type="tProcessType" default="None"/>
<xsd:attribute name="isClosed" type="xsd:boolean" default="false"/>
<xsd:attribute name="isExecutable" type="xsd:boolean"/>
<xsd:attribute name="definitionalCollaborationRef" type="xsd:QName" use="optional"/>
</xsd:extension>
</xsd:complexContent>
eclipse.bpmn2 on the other hand cannot follow this sequence as defined. Bypassing Semantic.xsd fixes the issue :)

I am trying to get a hold on javassist for one of our companies projects. I wrote this simple class for testing
public class Main {
public void test(){
ClassPool cp = ClassPool.getDefault();
CtClass entity = cp.makeClass("Entity");
try {
entity.addField(CtField.make(" public Integer id;",entity));
entity.addField(CtField.make(" public String name;", entity));
entity.addMethod(CtNewMethod.make("public void say() { System.out.println(12222);}",entity));
Class EntityClass = entity.toClass();
entity.writeFile("/tmp");
Object e= EntityClass.newInstance();
Field name = EntityClass.getField("name");
name.set("Ooldooz", e);
System.out.println(name.get(e));
} catch (CannotCompileException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
} catch (InstantiationException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
} catch (IllegalAccessException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
} catch (NoSuchFieldException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
} catch (IOException e) {
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
}
public static void main(String[] args){
Main main = new Main();
main.test();
}
}
Trying to run, I get this error:
>
> Exception in thread "main" java.lang.IllegalArgumentException: Can not set java.lang.String field Entity.name to java.lang.String
> at sun.reflect.UnsafeFieldAccessorImpl.throwSetIllegalArgumentException(UnsafeFieldAccessorImpl.java:146)

Can anybody help me out please?

[jBPM] - Loading processInstance/session via JPA, workItem executes before able to register workItems

Hey guys,
I've got a process that I run the 1st half until it hits a timer, at which time I persist the process instances to the DB. This portion works fine.
When retrieving the sessions, I find (based on stack exceptions & debugging) JBPM calls JPAWorkItemManager.internalExecuteWorkItem before I can register my workItemHandlers.
Right now I'm calling JPAKnowledgeService.loadStatefulKnowledgeSession, and immediately after calling ksession.getWorkItemManager().registerWorkItemHandler, but it seems like some kind of race condition occurs and the engine wants to execute immediately upon loading from the database.
Has anyone else run into this problem before?
