[kepler-users] The Deadlock Problem of DDF Kepler Workflow with Looping and Branching

Hi Dan,
Thanks for your help! I set the firingCountLimit of L3RN201412170001InitialSubmitionXml to 1 and it did not repeatedly execute. However, the execution of my workflow midway terminate and won’t run to trueInput of DDFBooleanSelect. I felt very confused with the looping and branching of DDF. It seems out of control. Is my workflow composed incorrect? Or kepler don’t support complicated ooping and branching? 
Thanks for your attention and look forward to your reply!
With regards,
Jie Zhang

Hi Jie,

Your animated gif shows the actor L3RN201412170001InitialSubmitionXml
repeatedly executing. You can configure the actor to only execute once by setting the firingCountLimit parameter to 1.

In general, actors that have no connected input ports will repeatedly execute. Unless you want this behavior, set the firingCountLimit to 1.
