I created a page in APEX Express 4.2.3.00.08. On the page there are two items: a text field named P55_KEY_ID and an LOV named P55_REASON with the values LOST, BROKEN, OTHER. I created a dynamic action that enables P55_REASON when P55_KEY_ID changes. Our business rule is if P55_KEY_ID has been changed then P55_REASON must have a value, i.e. not null. Can I define a validation on P55_REASON with a condition to test the disabled property of the page item with javascript, if it is disabled then return false otherwise true. Where would I place the following javascript?
IF $x(‘P55_REASON’).disabled then
Return false;
Else
Return true;
End if;
