If the associated schema object is deleted from the repository, the Developer tool retains the location of the method elements in the output mapping. When you show the output mapping, the
area still displays the location of the method elements in the
column for the output ports. If you associate another schema with the transformation, the Developer tool checks whether each location is valid. The Developer tool clears the location of method elements in the
area of the output mapping if the location is no longer valid.
