Oracle Forms

Hi all,
I'm using Oracle Forms Builder 10gR2/ I have the following issue: In a button i have trigger when it's being pressed. And then i change some prompt text of items. But my problem is how to return the original prompt text. Some kind of refresh or clear?


Here is a piece of code that changes the prompt text:

set_item_property('XXBG_CE_STATEMENT_LINES_NEW.AGENT_NO', PROMPT_TEXT, get_item_property('XXBG_CE_STATEMENT_LINES_NEW.AGENT_NO', prompt_text) || '*');

Thanks in advance,
Bahchevanov.
