Jim Dwyer [http://community.jboss.org/people/JimDwyer] created the discussion "jBPM5 - jbpm-gwt-console - java.lang.IllegalArgumentException: Could not connect task client" To view the discussion, visit: http://community.jboss.org/message/627574#627574 -------------------------------------------------------------- I am getting the error below the first time I click on Processes/Execution History. Process/ProcessOverview, Task/Personal Tasks and Tasks/Group Tasks.  It goes away after selecting each at least 1 time previously. I read in other posts about a "task service".  Is there such a thing?  I also read that this involved the h2.jar file.  If so how?  I am hoping somebody can shead some light on the this error.
