Forms and objects and accessing those objects

Hi all,

I have a window which contains a form and in the form contains an object I have created known as "MyContent1". From this object I can open a popup window. This popup contains a search form. At this time I am still able to call methods from the object on the parent window. However, if I perform a search (this is the purpose of the popup) which is a self-posting form and I try to call one of the object methods from the parent window I get nothing ( i mean it does nothing ). Also, if I try to see if that object exists using an alert it returns 'undefined'.

Why can I not access this object from the popup window after the form post?

TIA

Harold

Hi,

I have discontinued my efforts and went with a solution that already works, however would still like to resolve this as it adds greater functionality. The popup window code that I have include is the original. If you need more info then I would be glad to send you the templates that I was trying to use. Either way the javascript is the same in both instances. The only difference is that the original popup has no form post where as the new one did.

thx

This is the code from the parent window (less the .js files):

<script language=&quot;JavaScript1.2&quot;>
<!--

if (typeof eWebEditPro == &quot;object&quot;)
{
document.frmEdit.eWebEditProSubmitHandled=true;
eWebEditPro.create(&quot;MyContent1&quot;, 640, 500);
}

//-->
</script>

Here is the javascript code from the popup that accesses the object eWebEditPro[&quot;MyContent1&quot;]:
And btw, some of the code you see in here is tcl and storyserver, jicyww.

<head>
