Hi Alexey,
thanks for the quick answer. Unfortunately it does not work even with your hints.
My "org.jboss.tools.jst.web.kb"-entries seem to be correct.
Including the com.tc.pricing.sc in ui project's class path does not make any difference too. I have just tried it. One question: Should it not be sufficient to refer to the sc-project by the deployment assembly? (Our projects are all packed in one big EAR.)
I have just tried Eclipse Indigo and JBoss Tools 3.3. No improvement... :-(
