multiple iframes to fire another panel

[Neo]

Hi all,

I'am trying to develop an application using ext and I have some problems I need to solve.

My application consist on a layout with 2 panels, west and center. When click on the west panel a new tab should be opened on the center panel. Up to here its quite normal and I have managed to get this functionality easily.

Now here it comes the real problem: The west panel consist of an iframe including an html document. Let's call it html_in_frame_1.

Going on: htm_1 consist of an iframe including another html document. Let's call it html_in_frame_2.

I need a click on an element on html_in_frame_2 fires to open the new tab in center panel.

Is it possible to do this? is so, how? if not, what can I do?

Thanks :)

PD: I know it could seem strange to have this situation but i'm using, as a starting point, an open source application that works this way.
