Explanation

The Navigation Trap You have seen that the Pre-and Post-navigation triggers fire during navigation, and when they fail the internal cursor attempts to return to the current item(SYSTEM.CURSOR_ITEM).The diagram below illustrates the navigation trap. This can occur when a Pre-or Post-navigation trigger fails and attempts to return the logical cursor to its initial item. However, if the initial item has a Pre- Text- Item trigger that also fails the cursor has nowhere to go, and a fatal error occurs. Be sure to code against navigation trigger failure
