The JBPM projct has the following issues when running in GWT Dev mode on my machine. The following exception is raised on the initial screen:
Unable to complete your request. The following exception occurred: java.lang.ClassNotFoundException: org.drools.workbench.models.guided.dtable.backend.GuidedDecisionTableConverter.
When I access the data modeler I also receive this error:
Error: "An error occurred when the requested data model was loaded from server". The server error is: "Data model couldn't be loaded, path: PathImpl{uri='default://master@jbpm-playground/mortgages', fileName='mortgages', attrs={}}, projectPath: PathImpl{uri='default://master@jbpm-playground/mortgages', fileName='mortgages', attrs={}}."
