Please note that rolling back a dependency like Drools has a ripple effect into seam-gen. The deployed-jars*.list files must be updated (if the artifact name changes, as was the case with Drools 5 and MVEL), the IDE project files must be updated, and the Ivy dependencies file must be updated. Yes, it sucks, which is why we have seam-gen encore in the works...but I'm just saying that you have to let me know excactly when you are changing it so that I can react.

I blogged about release plans:

Marek, can you roll back the Drools 5 upgrade in trunk for now? We'll branch after in the release for 2.1/2.2.

Sorry to leave everyone hanging. Anne Louise is working on how we can best integrate Seam 2 w/ jBPM 4 / Drools 5 into EAP 5. We have a tentative plan, which should be finalised soon.

In my original plan, Pageflow was only targetted after July.

Pete, if one of your people can drive the pageflow migration, then I can be there to guide it.  That way we can move it forward to april.

Yes, I think we can do that (I was assuming that was the plan anyway).

Including jBPM 4 beta as part of your GA might not be a good idea.  jBPM database schema will change.  And that could cause serious upgrade problems for SEAM users using jBPM.  Also upgrade from jBPM 3 to jBPM 4 will be impossible for now.

Can you tell us what the earliest release we should put in 2.2.0 is? And roughly what date we can target? If we don't have time to do 2.2.0 and 2.2.1, I guess we could do:

Seam 2.2.0.BETA1 - Wednesday 22nd April
Seam 2.2.0.CR1 - Wednesday 13th May
Seam 2.2.0  - Wednesday 17th June

Tom and Anne-Louise, how do these dates fit your respective schedules?

regards, tom.

This Drools upgrade, and a probable upgrade to jBPM 4 (happening due to these products needed in the JBoss SOA platform 5, based on EAP 5, which in turn includes Seam) mean that we need to make the release Seam 2.2 (which I said would never happen, I know ;-)
Due to the concentration on Web Beans / Seam 3 there hasn't been a huge amount of activity recently, however 2.2 will include:
* 112 issues closed (please direct your thanks to Norman here - he has been soldiering away!)
* improvements to Seam-gen (Glassfish, IDEA etc.) from Dan
* big improvements to REST support - Christian and Jozef
* Drools and jBPM upgrades
So, I suggest that Norman and Marek (can you coordinate with each other) handle the jBPM upgrade (Tom just released alpha2, and plans the GA in the mid summer) - we should wait until there is a beta out I think for Seam 2.2 GA... Tom, any rough guess when this will be?
Assuming Tom has a beta, I propose this schedule:
Seam 2.2.0 CR1 - Wednesday 22nd April
Seam 2.2.0 - Wednesday 13th May
Seam 2.2.1 CR1 - Wednesday 17th June
Seam 2.2.1 - Wednesday 8th July (hopefully just after the jBPM GA)
This will be the first time for time-boxing our releases too, something we are doing for Web Beans, and will do for Seam3.
Anne-Louise, could you please comment on how these dates fit with EAP5 component freezes? Will we be able to get 2.2.1 in?

Subject: [JBoss JIRA] Commented: (JBSEAM-4011) Upgrade Drools framework integration to version 5

 [ ]

Stefano Travelli commented on JBSEAM-4011:

As far as I know, drools 5 is not a drop in replacement of drools 4.0.7. Lots of dependencies change (mvel and antlr for instance) and most of all there are several API changes that make Seam after changeset #10170 not compatible with Drools 4 forcing a migration to Drools 5 in the run time environment of existing applications.

At least, a detailed migration path for existing application is needed. However, even after accomplished all dependencies, rules in my application don't compile anymore.

Actually, in my opinion this upgrade is unfitted for a maintenance release of Seam.

Upgrade Drools framework integration to version 5

            Key: JBSEAM-4011
        Project: Seam
     Issue Type: Feature Request
     Components: Drools
       Reporter: Marek Novotny
       Assignee: Marek Novotny
        Fix For: 2.1.2.CR1

Upgrade Drools framework integration to current development version of Drools 5. It is now available 5.0.0.CR1 version.
