Seam JBPM Variable Instance and taskInstanceListForType
Hi, I'm manipulated the DVD-Sample a lot and have the problem that when I return to the admin-area from a page that begins and finishes a task.
The #{task.variables['creditId'] is now 0 and musst be 1 in the admin.xhtml....the firsttime before the first task is executed the variable is shon correctly. When the process is created the credit has business-scope and is also visible in the jbpm-database-table under jbpm_variableinstance.....
