Implementing a Universal Filter
You implement a universal filter the exact same way as you would implement a simple filter, with one exception. When implementing a universal filter, you need to extend com.ptc.core.ui.validation.DefaultUniversalValidationFilter. Otherwise, the implementation is exactly the same as a simple filter.
Suppose we wanted to implement the filter in the simple filter example as a universal filter instead. Here is what that class skeleton would look like as a universal filter:
public class MarkedForDeleteFilter extends
DefaultUniversalValidationFilter{
@Override
public UIValidationStatus preValidateAction(UIValidationKey key,
UIValidationCriteria criteria){
// ENABLE by default
UIValidationStatus status = UIValidationStatus.ENABLED;
WTReference contextObj = criteria.getContextObject();
if (/*contextObj.isMarkedForDelete() == */ true){
status = UIValidationStatus.HIDDEN;
}
return status;
}
}
