[rules-users] repository in 5.2.M2 crashes in 5.2.Final because of decision table serialization

[Michael Anstis]

How are you loading and compiling the dtable?

Guvnor uses org.drools.ide.common.server.util.GuidedDTXMLPersistence to
convert XML to and from the object model.

This in turn uses org.drools.ide.common.server.util.RepositoryUpgradeHelper
to convert from GuidedDecisionTable to GuidedDecisionTable52.

We had to make some essential changes for Guvnor 5.2 to support CEP
operators on the guided decision table.

With kind regards,

Mike
