Please, next time, attach it as an attachment, this is a mess. Thanks. Moving to java for evaluation...
*** Issue 64610 has been marked as a duplicate of this issue. ***
Deadlock is not a P3. Fix should be simple - invokelater the dialog, get it out of runAtomic().
Yes, it is P2, I overlooked the priority. Fix is not simple - dialog cannot be invoked later, because it is modal and has to block document reload.
The problem is in form editor. It accesses the MDR under the document lock (in the GandalfPersistenceManager.loadForm()), wich is forbidden. Reassigning...
> The problem is in form editor. It accesses the MDR under the document lock > (in the GandalfPersistenceManager.loadForm()), wich is forbidden. This is a superficial evaluation. The form must be loaded in AWT thread. We cannot do anything if the loading is invoked in this thread when there is a modal dialog holding the mentioned lock (note that even several invokeLaters doesn't help there). Reassigning back. It is not a problem of form that there is a document lock - we don't know anything about it. BTW: It is a very poor practice to hold some lock in AWT thread for a long time because you never know what is invoked there and the invoked tasks know nothing about your lock.

Thanks for your deep evaluation, but it is not java, but form module who is doing transaction in AWT. We agree that this is bad practice. We encourage JMI clients not to do transactions in AWT thread. Form module is violating it. Order off locking is declared: you cannot access MDR under document lock. It is not java module who is holding document lock.

You know, we are the form guys, we have to do things in AWT thread. ;-) > Order off locking is declared: you cannot access MDR under document lock. I can live with this rule if I know about the document lock, but the document lock is held by someone else lower on the stack of the AWT thread !?! > It is not java module who is holding document lock. I agree that it (probably :) is not an issue of java module. I should have reassigned it to openide/text, because the lock is held in CloneableEditorSupport. Happily I don't have to do it. The part of code that uncovered this problem has been rewritten (FormEditorSupport.java revision 1.180) and this deadlock should no longer occur.
