I am only aware of the changes made around the dtable XML.

Declarative fact types would be an interesting one as that had a few changes made too to support CEP (addition of annotations).

I am unaware of the difficulties with processes. Somebody else here may be able to comment.

Is the statement about backwards compatibility only true for CEP and decision tables, or does it pertain to upgrading from 5.2.M2 to Final as a whole? 
 
My project has been trying to upgrade from 5.2.M2 to Final, and we are having problems with our StatefulKnowledgeSession not containing any of the processes or fact types defined in our guvnor package.
 
Thanks,
Rob

That explains it.

The CEP changes were made between 5.2.M2 and Final.

Since 5.2.M2 was a beta Mark Proctor was OK not keeping backwards compatibility between the M2 and Final. I checked before making the changes.

Unfortunately the code-base only supports automatic conversion between 5.1.Final and 5.2.Final. Any guided decision tables made on 5.2.M1, 5.2.M2 and 5.2.CR1 are incompatible with 5.2.Final.

With kind regards,

Mike

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 the 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,

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-column52" 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 ?
