Please find the attached patch to fix RM #2945 : [Web based] Message "can't execute an empty query" displayed if user Click Yes on constrains trigger for view trigger
Fixed issues:
1. Disable "Constraint trigger?" option in View node
2. Disable "Constraint trigger?" option in edit mode for all the applicable nodes
3. Merged "Constraint trigger?" and "Constraint?" on the properties tab as both were for the same purpose but the "Constraint trigger?" was not showing correct data.
