- As I understand the problem, there are a total of five fields involved:
-
- FIELD1 the (possibly) null field under test
-
- FIELD2 the field you are LEAVING when the test occurs
-
- FIELD3 the actual field under test. i.e., If FIELD1 is null then
- enter this field -- If FIELD1 is not null and user says yes
- then update this field
-
- FIELD4 the alternate field to enter if FIELD1 is not null and
- user says no
-
- FIELD5 a test point to use to check the users response
-
- Also, these conditions can occur from various combinations of these fields,
- so:
-
- Attach a KEY-NXTFLD to FIELD2 that contains the following:
-
- if :field1 is null then
- GO_FIELD('field3');
- else
- :global.path1 := 'field3';
- :global.path2 := 'field4';
- go_field('field5');
- end if;
-
- FIELD5 is in a pop-up window with appropriate text to prompt
- the user for a Y or N response. Attach a KEY-NXTFLD trigger
- to FIELD5 that says:
-
- if :field5 = 'Y' then
- go_field(name_in('global.path1'));
- elsif :field5 = 'N' then
- go_field(name_in('global.path2'));
- else
- message('*** ERROR - response must be Y or N');
- bell;
- raise form_trigger_failure;
- end if;
-
- Hope this helps.
