Hi everybody,
I just ran into some very unexpected problem around interaction and
wanted to ask if the following is known behavior or even work in
progress for somebody:
- a DataNode is already in DataStorage with an interactor assigned
- you want to assign another parent to the DataNode, so to call
Remove(node), then Add(node, new_parent)
- the interactor is in a unhealthy/dead state now, having lost its
DataNode pointer (DataInteractor::DeletedNode got called)
For experimentation, I attached a patch against current master. Apply
the patch, activate the Point Set Interaction view, then add a new
PointSet, move the mouse over render windows, and have a look at the
console. You should see lots of messages like "WARNING:
EventStateMachine: Empty DataNode received along with this Event
000000000A780070"
I guess this is another variation of
http://bugs.mitk.org/show_bug.cgi?id=19329 where
DataInteractor::DeletedNode was introduced.
Has anybody already seen this behavior? Any ideas on how this should be
solved?
I created http://bugs.mitk.org/show_bug.cgi?id=19606 for this.
Regards,
Daniel
