I have a problem with my process composition.
I have a sub-process like that:<process-state name="process1"> <sub-process name="implementation" /> <variable name="crStatut" access="read,write" mapped-name="crStatut" /> <variable name="crId" access="read,write" mapped-name="crId" /> <transition name="Validation" to="statut 90"></transition> </process-state>
and when the process arrive to the "Process State" I hava an errorjava.lang.NullPointerException: can't create a process instance when processDefinition is null at org.jbpm.graph.exe.ProcessInstance.<init>(ProcessInstance.java:87) at org.jbpm.graph.exe.Token.createSubProcessInstance(Token.java:571) at org.jbpm.graph.node.ProcessState.execute(ProcessState.java:109) at org.jbpm.graph.def.Node.enter(Node.java:316)
However, i have deployed the processimplementation and there is a process definition in the database
Any suggestions?
Hay nicolemans72!
JBPM_PROCESSDEFINITION table it must possess one process definition with name "implementation".

dohoangn Feb 28, 2007 12:57 AM (in response to nicolemans72)I have the same problem even I already have deployed sub processs and the sub process name is in the table jbpm_processdefinition. Could you please give us a solution?

3. Re: Problem with process composition
dohoangn Feb 28, 2007 1:55 AM (in response to nicolemans72)I found the problem:
This is my main process:
<?xml version="1.0" encoding="UTF-8"?>
<process-definition
xmlns="urn:jbpm.org:jpdl-3.1" name="main">
<start-state name="start">
</start-state>
<end-state name="end"></end-state>
<process-state name="sub">
<sub-process name="sub"/>
</process-state>
</process-definition>
This is my sub process:
<?xml version="1.0" encoding="UTF-8"?>
<process-definition
xmlns="urn:jbpm.org:jpdl-3.1" name="sub">
<start-state name="start">
</start-state>
<end-state name="end"></end-state>
</process-definition>
When I deploy the sub process and main process:
public void deployProcessDefinition() {
// / Extract a process definition from the processdefinition.xml
// file.
ProcessDefinition processDefinition = ProcessDefinition.parseXmlResource("main/processdefinition.xml");
assertNotNull("Definition should not be null", processDefinition);
// Create an instance of the process definition.
ProcessInstance instance = new ProcessInstance(processDefinition);
JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
try {
// Deploy the process definition in the database
jbpmContext.deployProcessDefinition(processDefinition);
} finally {
// Tear down the pojo persistence context.
// This includes flush the SQL for inserting the process
// definition
// to the database.
jbpmContext.close();
}
}
It adds new records in all neccessary tables but it did not insert the sub process definition id (subprocessdefinition_)
into table jbpm_node, after I manually insert this id, it works
How could we fix this bug?
