Hi friends
I have developed a form of Query_Find Type.
In the QUERY_FIND Block,i've set a field as requied.
But when i push the "Find" button without input that field,there is
no hints of FRM-40202:Field must be entered. and i was lead to the
"result" block straightly.
can anybody tell me in which case will this kind of issue happens?

Thanks in advance.

You could try to modify WHEN-BUTTON-PRESSED trigger on the "find" button, such as

if :query_find.field is null then
  message('You did not enter search criteria');
  raise form_trigger_failure;
else
  go_block('result');
  execute_query;
end if;

Because required is designed to ensure you enter data when inserting or updating a record to save. It only does anything if the record_status is INSERT or CHANGED.
