Hi Jobinesh,
ReplyDeleteTry replace the panel window in the popup with a dialog component , your solution will work only when the dialog cancel button is pressed but when Ok button pressed the re-activation is not working ... do you have any idea about this issue.
Thanks , Mahmoud Abdultawab
Hi Jobinesh,
ReplyDeleteWe have to put the same popup canceled listener code inside the dialog listener to invert the condition.
public void dialogListener(DialogEvent dialogEvent) {
// Add event code here...
ADFContext.getCurrent().getPageFlowScope().put("forceActivate", "false");
}
Sorry for the disturbance.
Excellent blog with good information it is really useful.
