I am new to oracle forms and i'm updating existing code. All i want to do is disable a button on a certain condition...

if fdata_rec.frozen = 'Y' then
:base_buttons.flight_departed := 'FROZEN';
elsif fdata_rec.flight_cancelled = 'Y' then
:base_buttons.flight_departed := 'FLIGHT CANCELLED';
set_item_property('base_buttons.push_merge',enabled,property_false); -- @ad - BZ4582
elsif fdata_rec.fdept_actual_dt is not NULL then
:base_buttons.flight_departed := 'FLIGHT DEPARTED';
set_item_property('base_buttons.push_merge',enabled,property_false); -- @ad - BZ4582
else
:base_buttons.flight_departed := NULL;
end if;

I added the 2 lines ending in @ad - BZ4582. The 'FLIGHT DEPARTED' displayes but the button is not greyed out. What am i doing wrong?? I moved that same line above the if/else block but it still does not grey out. HELP!!!

thanks for any help.

Please read the 'sticky' at the top of the forum. Please use 'code' tags.

You did recompile and generate the form, right?

Put a 'message('asdf');pause;' pair of commands in your modifed code to PROVE that you are running the modified version of the form.

Hi David,

I did recompile & regenerate the form. I changed one of the labels and it displayed on the form.

I was able to make the button disapper alltogether but not just grey out.

thanks!

Please confirm that

set_item_property('base_buttons.push_merge',visible,property_false);

causes the button to 'disappear' but

set_item_property('base_buttons.push_merge',enabled,property_false);

does not cause any visual change at all.

Hi David

I found the problem Smile

After I was disabling the button, later in the process (which I did not realize was being called) other code was enabling it again.

thanks for your help!
