Hi,
I wanted to discuss one scenario.
From a main window, I open a javascript popup window, in that i have a form_remote_tag call. On the completion of this call, i want some server side code to execute and form to be submitted, after that is done i want the pop up window to close and after that a DOM element to be updated in the main window.
So am having trouble with the last part i.e. updating a DOM in my main window. So how can i make it work.
Thanks in advance.

Sorry I don't have a direct answer for you, but you could make a CSS style popup in the main window using something like Redcloth. Then you don't have to worry with two windows.
RedBox not Redcloth. Sorry.
I once did this:
I created a javascript function in the main window that is able to update the DOM element. In the method that is called when submitting the form in the popup, I returned some RJS. Here I call the javascript function in the main window, reachable through "window.opener"
It looks something like:
page << "if(window.opener) window.opener.myUpdateFunction(someParams)"
Greetings,
Wouter

That's correct. The example given executes a javascript function in the main window. When opening a popup, the popup window should have a DOM element called "opener", through which you can reach the main window.
Hi,
I tired this today but somehow couldnt get it to work.
I invoked a popup, then on form submission from the popup i rendered an RJS that has the code that says page << "if(window.opener) window.opener.myUpdateFunction()"
and this myUpdateFunction() is a javascript function defined in the layout of the main window. but its not getting invoked. Any thoughts on this.
