While closing a Dawn-based editor (and its CDOTransaction) the exception below is thrown. The cause for the exception is already described in Bug 314186. Though the exception has its root in the CDO core itself in this case it is triggered by an unnecessary notifyChanged() call from the DawnTransactionChangeRecorder. So I think in this special case this could be handled in Dawn itself. java.lang.IllegalStateException at

Created attachment 176639 [details] Patch v1 This fix solves the problem. But actually this is rather a fix basing on the fact that Dawn currently tries to combine the transaction framework CDO offers and the one provided be the TransactionalEditing domain. From CDO point of view it would be better to have a CDO based TransactionalEditingDomain. But until we have something like this fix will work fine ;)
