Hi all, Has anyone tried from the lastSuccessfulBuild - #6023, the drools flow part?? i.e. create a process in guvnor and view it from gwt-console or gwt-console-server or should we not touch that yet?? and play with the 5.1 version of the gwt-console/gwt-console-server?? The log with the exceptions follows and it seems that org.drools.persistence.processinstance.variabletypes.JPAPersistedVariable is not found. Tried to place the package containing the variabletypes from drools-persistence-jpa-5.1.1 into drools-flow-persistence-jpa-5.2.0.SNAPSHOT.jar of gwt-console-server-drools.war but no luck, I get another exception and a new adventure begins.... Any help will be greatly appreciated, thank you!! 2010-11-17 11:32:51,578 INFO [STDOUT] 11:32:51,578 INFO [Environment] Bytecode provider name : javassist 2010-11-17 11:32:51,578 INFO [STDOUT]
