cross-window javascript events

Question

I am launching a popup window with window.open(...) and I pass an elementId to the new popup window.

Then during startup of the popup window I find the element in the opener window that matches the elementId passed to the popup. Then the popup subscribes to events on that element using jQuery.bind(...). Then from inside the opener window I fire these events using jQuery.trigger(...), I also tried triggerHandlers.

The problem is that my popup's eventHandlers never get called. I can subscribe to the events from within inside the opener window no problem. However, when I try from the popup, it doesn't work.

Does anyone have any ideas on how to fix this? Is this some kind of security description?

Thanks a lot for reading!
