jbpm integration problem - about context instance

[jnesta]

I can deploy new process successfuly, but when I want to store variables in ContextInstance, it failed.

code snippet:
this.jbpmTemplate.execute(new JbpmCallback(){

/**
* {@inheritDoc}
*/
public Object doInJbpm(JbpmContext context)
throws JbpmException {
GraphSession gs = context.getGraphSession();
ProcessDefinition pd = gs.findLatestProcessDefinition("dbtest");
ProcessInstance pi = pd.createProcessInstance();
ContextInstance ci = pi.getContextInstance();
ci.setVariable("name", "jnesta");
context.save(pi);
return null;
}

});

if I remove the line code of "ci.setVariable("name", "jnesta");", it's ok.

the error messages:

After change a process definition, it 's ok.

[jnesta]

It runs successfully with process:
ProcessDefinition processDefinition = ProcessDefinition
.parseXmlString("<process-definition name='howareyou'>"
+ " <start-state name='start'>"
+ " <transition to='s' />" + " </start-state>"
+ " <state name='s'>" + " <transition to='end' />"
+ " </state>" + " <end-state name='end' />"
+ "</process-definition>");



But it fails with process:
ProcessDefinition definition = new ProcessDefinition();
definition.setName("dbtest");

Transition open = new Transition("open");
open.setProcessDefinition(definition);

StartState newS = new StartState("new");
newS.addLeavingTransition(open);

State openS = new State("open");
openS.addArrivingTransition(open);

open.setFrom(newS);
open.setTo(openS);

EndState end = new EndState("close");

Transition close = new Transition("close");
close.setFrom(openS);
close.setTo(end);
close.setProcessDefinition(definition);
openS.addLeavingTransition(close);
end.addArrivingTransition(close);

definition.setStartState(newS);
definition.addNode(openS);
definition.addNode(end);

Thanks in advance.

I can deploy new process successfuly, but when I want to store variables in ContextInstance, it failed.

Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: org.jbpm.context.exe.TokenVariableMap

I don't know that much about JBPM but can tell you what the Hibernate message means.

It's saying you are trying to save one object which contains another unsaved object (org.jbpm.context.exe.TokenVariableMap i.e. your variables).

Normally in Hibernate you set up your mappings so it cascades through, saving unsaved object children before saving the parent (i.e. cascaded saves)). Obviously the JBPM mapping isn't doing this.

My guess is you are saving things in the wrong order - it seems that you are trying to save the ProcessInstance without having first saved the ContextInstance - would that make sense ?

I agree with you in hibernate message.

Now I think that the problem in defining jbpm process with jbpm's api.

What I missed?

Any idea? Thanks in advance.

[jnesta]

Using codes as follows instead of new ProcessDefinition, it's ok.

ProcessDefinition definition = ProcessDefinition.createNewProcessDefinition();

[eren.aykin]

I was having a similar problem. After I added

context.deployProcessDefinition(processDefinition) ;

before context.save(processInstance), the problem got resolved.

The reason for the error was trying to save the process instance, without saving the process definition first.
