Hi Folks,
technical question: can anyone suggest on how to avoid / recover from
InvalidItemStateExceptions?
Here’s the use case/problem:
* we’re using advanced cache / notifyFlushListeningPolicy
* we’re bulk creating tons of nodes in various workspaces using a bulk action;
the action is performed in system context
* nodes are created just fine, this is all right, however…
* PROBLEM: updating the lastUpdateTimeStamp property fails with the exception
below [1]…
* interesting: the exception does not appear if I perform the operation for the
first time after starting Magnolia.. it seems that somehow the state is not
written back correctly in the NotifyFlushListeningPolicy?
Here some concrete questions?
* did anyone experience the same issues with the NotifyFlushListeningPolicy?
* since we know we’re doing lots of stuff in the workspaces: is there a way to
temporarily turn off updating this property and just writing it once?
* is there a way to recover from an InvalidItemState in some way?
* any other idea to avoid this exception?
Thanks in advance,
cheers,
Vivian
