I have the same problem where my removeTaskInstance isnt actually saving the
changes to the db. My task instance still exists after calling that method.

Yep
| Hibernate: select processdef0_.ID_ ...
| Hibernate: insert into JBPM_TOKEN ...
| Hibernate: insert into JBPM_PROCESSINSTANCE ...
| Hibernate: select definition0_.PROCESSDEFINITION_ ...
| Hibernate: select events0_.PROCESSDEFINITION_ ...
| Hibernate: select startstate0_.ID_ ...
Hi!
After turning on the show sql parameter i saw that no DELETE statement appears
in my console.
So i do this test case that is OK and continues to not show any DELETE
jbpm.TASKINSTANCE...:
| public void testToken() {
| JbpmContext jc = jbpmConfiguration.createJbpmContext();
do you see sql statements at all?

Sorry, the real code is this:
| public void removeStateProcessInstance(Integer keyRef, String processNname,
String state) {
| JbpmContext jc = jbpmConfiguration.createJbpmContext();
| TaskMgmtSession tms = jc.getTaskMgmtSession();
| try {
|
don't see anything wrong with that at first site. Are you sure anthing 'should'
be removed.? Do you see in the debug of jbpm that anything is being tried
to be removed?
And btw, why do you want to remove taskinstances from the db?

I Ronald,
If i delete the specific row in jbpm_logs then i can delete the taskInstance.
Id like to give to the user the possibility of making undo.
Can Process logs be used to implement the undo?
Thanks!

Aren't there any exceptions then? Like fk contraint violations???
And yes, using the logs is one of the things to use when implementing undo. See
jbpm 2.0 on how that was done and look at the jira for some undo info
View the original post :
No exceptions :(
The code i show to you runs perfectly and in debug i inspect the return of
getTaskInstances method and the taskInstances are removed...but after closing
the context my db remains the same!! :)
Ok, im going to read the documentation.
But btw the best way to implementing undo is
using the processlogs plays an important role for sure, but there is more to it
(details unknown to me)
If you turn on hibernate sql showing, do you see statements that they are
removed? Other things I'm thinking of are: transaction not committed, hibernate
config to fail silently if there are
10 matches
