In light of no complaints I've updated the version of Errai in droolsjbpm-parent to 2.2.0.Final today.
With kind regards,
I'd like to move the errai verison from 2.2.0-SNAPSHOT used in droolsjbpm-parent/pom.xml to 2.2.0.Final.
If your UberFire application inherits from this parent pom you shouldn't have any problems... but if for some reason you have your own parent you would need to make similar changes.
Please confirm you don't have issues and I'll do the update next week.
