can't update or delete variables

[dfrenkiel]

hello.

i can successfully create process variables but i can't update or delete them.

i have hibernate logging sql queries and it does nothing with new or deleted variables.

here's some code where i'm trying to delete a variable called "phoneNumber"

after running this code the process instance still has the variable.

=======================

ProcessInstance processInstance = jbpmContext.loadProcessInstanceForUpdate(8);

ContextInstance contextInstance = processInstance.getContextInstance();

contextInstance.deleteVariable("phoneNumber");

jbpmContext.save(processInstance);
jbpmContext.close();

=======================

the result is the same if i try to update the variable - it remains unchanged.

is there something else i need to do to enable variable updates and deletes?

thanks very much for any assistance.

after some more experimentation i am able to change variables by explicitly saving the token variable map.

for example, to update a date variable:

Token rootToken = processInstance.getRootToken();

contextInstance.setVariable("timeNow", new Date(), rootToken);
saveHibernateObject(contextInstance.getTokenVariableMap(rootToken));

so it appear to be just a hibernate cascade issue or something.

or is this just the way it needs to be done?

thanks.
