Runtime error 'Call to procedure "&P1" failed'

[Mockenrue]

I have a 6i form with a button that performs a GO_BLOCK statement to navigate to another block. When omitting a required field before pressing the button, Forms detects this but the error message seems incomplete:

'Call to procedure "&P1" failed'

I can circumvent this by preceding the GO_BLOCK statement by:

VALIDATE('RECORD_SCOPE');
IF NOT FORMS_SUCCESS THEN
RAISE FORM_TRIGGER_FAILURE;
END IF;

In that case the correct message 'FRM-40202 Field must be entered' is raised,
however, the cursor is not placed in the omitted required field anymore, which is
confusing for the user.

Questions:
- Why is the &P1 parameter not substituted ?
- In 2nd case, why is the cursor not automatically positioned in the omitted field ?

Forms does not use & as a placeholder in pl/sql.
Forms prohibits from LEAVING an empty mandatory field, but how shall it work if there are 2 empty fields? Try to develop more specific logic.
