Dynamically set the sequence of an Item

Question

Hi,
I have three record types and am trying to dynamically set where it appears on the form.
The 3 record types are MEETING REGISTER, MARKET PROBLEM AND BROADCAST CHANGE.
If the user creates a record with a type of MEETING REGISTER then I want a field called 'duration' to have a sequence of 57, if it is either of the other 2 types then I want it to appear further down the form with a sequence of 241.
I have tried creating a dummy text item called 'P2_DURATION_SEQ' at the top of the form with a default function of:
declare
v_dur_seq NUMBER;
BEGIN
IF :P2_RECORD_TYPE IN ('MEETING REGISTER')
THEN v_dur_seq := 57;
ELSE v_dur_seq := 241;
END IF;
RETURN v_dur_seq;
END;
and tried putting &P2_DURATION_SEQ. in the sequence field of the duration field properties with no success.
Any advice would be great.
Thanks
Chris

Hello Chris,
If you have just the one field, or just a couple, that needs to dynamically change sequence (I wouldn't suggest the following if you have many because it could become quite a maintenance headache), you can try this:
1) Define three "duration" fields, say P1_DURATION_MR, P1_DURATION_MP and P1_DURATION_BC. Define their sequence to display wherever each needs to be, respectively.
2) Map all three to the same database column.
3) Make each conditional on the record type being "MEETING REGISTER", "MARKET PROBLEM" or "BROADCAST CHANGE" respectively.
Then, if the record type is "MEETING REGISTER", P1_DURATION will render where it needs to and the other two will not render, etc.
Hope this helps,
John
