Hi Sjoerd I am thinking that the triggering of the procedure is not through initProc or donePorc of the CDF parameter. We may use triggering functions calls via event. The corresponding API is...

Hi Sjoerd I try the method I mentioned above. It does not work. The reason might be that when using the GUI to instantiate an instance, "ddCreateObj()" is not used. Best Regards Yi
