Designing a "pop-out" interface that automatically updates - even possible?
<p>So I developed this web application, which has several multiple select boxes on an admin page - each of these boxes contains multiple values, which we will call criteria.</p>

<p>The criteria in these boxes are generated on a form on another page and stored separately in another table in the database. The big problem is that my boss wants to have a new criteria editing page pop out in a new window, or a different tab of the same browser, allow the user to add one or multiple criteria, and have these update in the main admin browser window in real-time.</p>

<p>Now, if it was in the same window, my immediate thoughts would go to AJAX. However, because it will be in two separate browser windows, I don't believe this is a feasible solution.</p>

<p>Is there anyway (other than some form of COM programming or other OS-y methods, which I don't want to get into) to pass a value between the two browser windows, without having to reload the main page? That is a critical issue here - the main page cannot be reloaded at all during this process.</p>

<p>Would frames be the answer (thus getting rid of the dual browser window problem by not having two windows)? Something else? This is beyond my range of experience.</p>
