Please mention this on the Drools forums so they have visibility.
Thanks. The Drools team report that this looks like the same issue they fixed a while ago. JBossESB 4.2.1 CP1 supports Drools 4.0.4. You can always check it out from svn yourself if you want.
Sorry for basic question...
I cannot see JBossESB 4.2.1 CP1 tag in svn.....
Shall I check out http://anonsvn.labs.jboss.com/labs/jbossesb/tags/JBESB_4_2_1_GA_CP_IR8/?
There is still drools-4.0.2, but it never mind, I will copy drools-4.0.4 libs for me...
The project releases have not been updated from 4.0.2 but this is underway now.
The platform releases do have 4.0.4 but this is something that the SOA platform guys overlayed on top of our codebase. You should be able to do the same with the 4.0.4 libs.
There are three JIRAs which are currently active, these will result in an update of drools being taken into the ESB project for the 4.4. release.
Apologies if this is causing issues in the meantime.
If this issue is related to the update listeners then there is a workaround for the ESB environment on http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4157414
You can use this until drools is upgraded.
