How to show result from process in popup page?

Question

<br>We want to use one popup page for many information in application. So we want to make the following thing.
<br>We want to execute process and show result in popup page (through hidden parameter-"P2_MESSAGE").
<br>We also assign title of region on that popup page through "P2_TITLE".
<br>What I do not know is how to show popup after process-branch problem.
<br>Process is executed from one button. Button is located on page "28" and popup page is "2"
<br>Code for javascript should be like:
<br>
javascript:popupURL('f?p=&APP_ID.:2:&APP_SESSION.::::P2_TITLE,P2_MESSAGE:'+'status '+','+'&P28_X.')<br>THX

Answer 1

I have found in one thread:
<br>
<br>1) create an application item APP_ONLOAD (of course you can choose your own name)
<br>2) create an application level before footer computation on APP_ONLOAD to clear the item after the page is generated.
<br>3) place &APP_ONLOAD. (dot also) in the on load property of the page.
<br>4) fill the APP_ONLOAD using :APP_ONLOAD := 'onload="your own javascript to call a popup window;"' in the plsql of an after On Submit - After Computations and Validations process (type PL/SQL anonymous block)
Fill the when button pressed property of the process with the button you want to use to show the popup.
<br>5) create a branch to branch to the current page (or a other if you wish)
<br>
Looks OK but when I create in PL/SQL js with "&" signe, which I use for filling some hidden values in popup page I get error.
begin
  is_test_ok (1, :P28_X);
  :APP_ONLOAD := 'onload="javascript:popupHeightURL(''f?p=&APP_ID.:2:&APP_SESSION.::::P2_TITLE,P2_MESSAGE:''+''statusu testova''+'','+''&P28_X.'')"';
end;<br>Should I use ASCII codes for that or what? Any example please!
<br>THX
