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

Hi all We tried to use the 5.2.Final version of Guvnor, but the compilation fails with an error saying that class "dtable" does not exists. After looking more depply, it appears that the XML storage format has changed in 5.2.Final : - root XML is now  " decision-table52 " instead of "dtable" - pattern is now " org.drools.guvnor.client.modeldriven.dt52.Pattern52 " with some condition-column grouped by fact, instead of independant condition-column - pattern is now " org.drools.guvnor.client.modeldriven.dt52.Pattern52 " with some condition-column grouped by fact, instead of independant condition-column - actions is now " insert-fact-column 52" instead of the same thing without version in it, but this time no structure changes ... Is there a way to migrate old tables to new format ? Changing a repository.xml by subtitutions is OK ? Do we have to plan such problems for future versions ?
