Events specified by event case are not compatible with each other

If an event handling case handles multiple events, the events must have compatible event data. With Filter events, you can validate or change the event data before the LabVIEW user interface can process it, or you can discard the event data entirely, preventing the change from affecting the VI. Because you can modify the data, the Event structure cannot merge the data.

With Notify events, only the event data fields that are compatible with the events configured for that case are available on the left side of the case. You cannot configure a single event case to handle both Filter and Notify events.

Complete the following steps to correct this error.

  1. Make sure the case you want to edit is visible.
  2. Right-click the Event structure.
  3. Select Edit Events Handled by This Case from the shortcut menu to display the Edit Events dialog box.
  4. Edit the case so all events being handled in that case have compatible data.
