Comment 2 Pavel Flaska 2003-09-19 14:27:10 UTC 
CodeGenerator running in transaction cannot finish its work because of
waiting for the document (prepareDocument() ) lock. -- Bridge is
trying to refresh its state (it is trying to start read transaction).
-- its thread holds document. Unfortunatelly, it cannot go into
because of generator holds it.
Fixing problem in generator (do not remove elemnts from removed
sources) will probably solve this problem. -- Will investigate
possible other scenarios which can cause the same problem.
Comment 3 Pavel Flaska 2003-09-25 10:21:53 UTC 
Fixed. CodeGenerator does not generate elements, which are part of the
removed source. There is no need to obtain lock in prepareDocument(),
the thread should not lock each other.
