How can I allow for query mode?
I have a form which has three radio buttons, 'A', 'B' and 'F' which have a WHEN-RADIO-CHANGED trigger attached to them. When the user clicks on the 'F' radio button, I want it to take certain actions if the user is entering a new script into the form.The content of the trigger is listed below. However, the problem arises when the user is in query mode and clicks on the radio button, for example, if the user wants to do a search on scripts of type 'A', 'B' or 'F'. When this happens, the following error pops up: "FRM-41009: Function key not allowed. Press Ctrl+F1 for list of valid keys." What I would like is for the code in the trigger to be bypassed if the user is in query mode by inserting an IF statement, e.g., IF "user NOT in query-mode THEN execute the code in the trigger." How do I check whether the user is in query mode?
Content of Trigger:
BEGIN
IF :a.a_type = 'F' THEN
GO_BLOCK('c_a');
:a.a_columns := Null;
Set_Status('P');
IF :GLOBAL.database_instance <> 'MAIN' THEN
set_item_property('a.a_rev
set_item_property('a.a_rev
GO_BLOCK('a');
END IF;
ELSE
Set_Status('A');
set_item_property('c_a.exe
IF :GLOBAL.database_instance <> 'MAIN' THEN
set_item_property('a.a_rev
:a.a_reviewed_ind := 'N';
:a.a_reviewed_user := Null;
GO_BLOCK('a');
END IF;
END IF;
END;

I don't think there is a direct way of doing it.
However you could set a global variable or pass a parameter to your form while in query mode and use that variable to base your if condition

Jrb1, where would I put that code? Would I put it in the WHEN_RADIO_CHANGED trigger?
ASKER
Sathyagiri, so in other words, I would have to assign the global variable the value when the user presses the F7 key or is there any other way to do it?
You'd put that on the ON-ERROR trigger on your form.
?? you could read out a blockproperty which says that the block is currently in query-mode
well, no forms on hand, but i guess the property sounds like status

You also may be able to catch the error in the trigger code itself.

You will put it in the ENTER-QUERY_MODE trigger I guess. Not sure.

Jrb1, your suggestion works! Thank you! Also thanks for your help, kretzschmar and sathyagiri
