[deepamehta-devel] creating topics from listener method

Hi guys,
I am trying to resolve a straightforward thing:
Upon log-in I want to check whether a bunch of user related topics exist
and if they don't create them.
So I implement the PostLoginUserListener's postLoginUser method and do
my checks.
Then there is the method that creates new topics which looks like this:
ChildTopicsModel childs = mf.newChildTopicsModel();
// put data inside
// <removed for the example>
Topic t = dm4.createTopic(mf.newTopicModel(NS.user.self(), childs));
long wsId =
wsService.getAssignedWorkspace(acService.getUsernameTopic(userName).getId()).getId();
assignToWorkspace(wsId, t);
When this code runs it will actually cause an exception because there is
no transaction context.
If it were a normal rest method I'd add @Transactional and all would be
fine. However I don't have this option, so I thought I'd do a TX myself
and surrounded the above code with:
DeepaMehtaTransaction tx = dm4.beginTx();
// code from above
tx.finish();
tx.success();
Unfortunately that does not do anything. I don't see errors in the log
but the actual topic is not created either.
*puzzled*
Any idea what I am doing wrong?
All the best,
Robert
