jBPM3 How to update an existing process definition using Java?

[witik]

I'm retrieving a process definition from the database like so:

/* session is a GraphSession,
and processDefinitionId is a Id of an existing processDefinition in the database. */
ProcessDefinition processDefinition = session.getProcessDefinition(processDefinitionId);

Then I'm editing the processDefinition (for instance changing the Description)

processDefinition.setDescription("This is a new description");

Finally I want to commit these changes to the database.

session.deployProcessDefinition(processDefinition); // session is still a GraphSession

The problem is that after the deploy, no changes are visible.

Hi Alexander,

Could you specify what you mean by "no changes are visible"?

Changes will only be visible in new processes -- you can not modify the process definitions of existing/running process instances.

Hi Marco,

When I execute a query listing all the ProcessDefinitions

SELECT NAME_, VERSION_, DESCRIPTION_
FROM JBPM_PROCESSDEFINITION
ORDER BY NAME_

there's no new version visible in the database, nor is there any change in description.
