Navigation Bar - links

Question

I have an application with a button in the navigation bar which opens an URL. In this URL are a number of (3 or 4) user preference values which are derived from tables held within the database.
Currently I am running an "On Create Session" application process which loads up some hidden fields on page 1 of the app. These are then referenced by a javascript function to link to the dynamically created URL. Within this js function I am using a html_GetElement('P1_PARAM').value to build up the URL string and this works just fine... for page 1.
I don't want to load up hidden fields on every page to allow the Navigation Bar buttons to work from each page so I guess application level items would be the practical objects to use here.
The problem I am having then lies in the fact that the application items are not rendered in the html and so therefore are not going to be seen by the html_GetElement() function.
Can anyone point me in the right direction here.
Thanks in advance,
Mike

Hi Mike,
I think that the value of any Application Item is rendered.
1. If you check the session state that item is not shown, but is there.
I set Page region/Title to “Name   F111_TEST” and it’s there
2. If you use Debug can see that the value of the Application Item “0.20: ...F111_TEST session state saving same value: Hello Konsta”.
3. Define an Application Item and do Application Computation on Before Regions for instance. Set Static Assignment 20 for instance. The VAT in Bulgaria is fixed to 20%.
4. In Page Attributes/HTML Header:
<script language="JavaScript" type="text/javascript">
<!--
function sumVAT(){
function getVal(item){
if(document.getElementById(item).value != "")
return parseFloat(document.getElementById(item).value);
else
return 0;
document.getElementById('P306_VAT').value =
getVal('P306_SALES_PRICE') * &F101_TEST. / 100;
//-->
</script>
5. You probably have tried getVal(' F101_TEST ') instate &F101_TEST.
The example above shows that Application Items are rendered and one could use them in JavaScript. I will be happy if you send a complete solution for Navigation bar.
Good luck
