I am working on jBPM 4.3.
I wrote a converter to convert one of my classes into a Long (it's coming from JPA
with the Long being its key).
I added it to jbpm.variables.types.xml and using the following code I add the variable to
my instance.
Map<String, Object> variables = new HashMap<String, Object>();
variables.put("dataEntity", dataEntity);
ProcessInstance instance = processEngine.getExecutionService()
.startProcessInstanceByKey("dataEntityProcess", variables);
The converter gets triggered and the variable is converted to a Long.
In my process I have a java task:
<java name="activateAccount" expr="#{dataEntityProcessDAO}"
method="activate">
<arg>
<object expr="#{dataEntity}" />
</arg>
<transition to="end" />
</java>
As soon as my process reaches the task I get
org.jbpm.pvm.internal.wire.WireException: method activate(java.lang.Long) is not available
on object com.hre.portaldb.crosscommon.base.processes.DataEntityProcessDAOImpl@40b11a9f
(com.hre.portaldb.crosscommon.base.processes.DataEntityProcessDAOImpl)
at
org.jbpm.pvm.internal.wire.descriptor.ObjectDescriptor.invokeMethod(ObjectDescriptor.java:206)
at org.jbpm.jpdl.internal.activity.JavaActivity.perform(JavaActivity.java:76)
The revert method of my converter is never called and it tries to use the Long on the
method that takes DataEntity as input.
What am I doing wrong?
Thx
Jochen
