See attached screenshots (in JBDS-1865) - if an ESB project is created, and SOA-P 5.2 ER4 server is defined as the runtime - the BPELInvoke action is not included in the OOTB action list.

I also tried explicitly adding the server/production/deploy/riftsaw-esb.esb/lib/jbossesb-bpel-2.3.1.Final.jar file to the runtime and the ESB project classpath.

Slava, can you look into this? If the file is on the classpath, I'm wondering why your editor tweak (JBIDE-6609) isn't working in SOA-P 5.2.
