Hi, I use an event structure. and I have 2 occurences of the same customized control. The customized control is a cluster of two controls.Therefore I can monitor a value change of the controls in the event structure by looking at Occur1.Control1, Occur1.Control2, Occur2.Control1, and Occur2.Control2.Now I use Occur1.Control1 and Occur2.Control1 to trigger an event.Depending on the triggering occurence I would like to change the value of Control2 in the same occurance.I.e., if Occur1.Control1 triggers the event -> change Occur1.Control2; if Occur2.Control1 triggers the event -> change Occur2.Control2.How do I find out if Occur1 or Occur2 triggered the event?When I take the CtrlRef from the data node in the event structure, it just tells me Control1, but not Occur1.Control1 or Occur2.Control1. Thanks,Dan
