Post Query freezing forms [message #650207]

Hello,

I'm having trouble with some non-database items on my form. When I'm at the first record and I press the key up button on the keyboard in a non-database text item, my forms just freezes on the web. For the database text items, I get the 'FRM-40100: at first record' error when I press key up on the text item. I want the same error for the non-database text items instead of the form freezing. Is there any way i can fix this?

Any help would be great. Thank you.

What happens if you "trap" it with a KEY-UP (block level) trigger, such as

if :system.trigger_record = 1 then
   message('At first record');
   raise form_trigger_failure;
else
   previous_record;
end if;

Alternatively, instead of the PREVIOUS_RECORD, try the UP built-in.

Thank you very much, they both worked on my form.

I'm getting the same freezing issue when I press key down the last record. Would I use the DOWN built-in for that?

This is a key-down trigger I tried:

if :system.trigger_record <> 1 then
   message('At Last record');
   raise form_trigger_failure;
else
   DOWN;
end if;

I tried this, but i wasn't going further than the second record when pressing key down.

It is a different system variable:

if :system.last_record = 'TRUE' then
   message('At last record');
   ...

That resolved my issue with that form. I used the DOWN built-in in the else condition. Thank you helping me.

OK; though, it was the :SYSTEM.LAST_RECORD, not the DOWN built-in which fixed the problem.
