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

[Vincent LEGENDRE]

We had a repository done with 5.2.M2. 

We had exported this in a xml, and import this xml in a new 5.2.Final version 



We don't use the classes below (at least not intentionnaly), we simply try to get the source (from Guvnor URL) or "compile" a package (from t he package view). 


Is there a way to use org.drools.ide.common.server.util.RepositoryUpgradeHelper to convert the repository explicitely ?

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

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 

- 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 ?
