That was pretty much the idea I had in mind. I'd almost be tempted to sit down and try to create a module that you could bolt onto Dojo to make it work with iframes as if they were part of the global page (which would be bundled with any and all security issues it might have). It would be nice to be able to set a djconfig for usesIframes and just add things like you have here, and byId and the positioning things as extensions to the existing code.

With this in practice, you might want to be careful that you don't get unexpected cross frame communication. In the same way we created dojo.localPublish you could make a dojo.globalPublish leaving dojo.publish intact. Depends how you're using it and if you want every use to let every frame know what's going on.

We create a version of dojo.publish that will only publish locally so that there's a way of publishing only to this page. 2. We dojo.connect to the real dojo.publish so that every time it's called, connect pushes the values going into the publish, through to the top window along with a reference of the local window. 3. top window publishes the information out over a channel "globalChannel" to all subscribed frame windows. 4. every frame gets the message (including the orig) and we use the current window compared to the reference window to make sure we don't repeat ourselves. All windows other than the source publish it locally with dojo.localPublish. Sorry..to elaborate further..

It uses the pub sub system to repeat around the pages always bouncing off the top window. Drop that into all frames.

Any chance you can give some background to what you're doing here. I'm especially intrigued with the: <code> dojo.connect(dojo, "publish", ..... </code> I didn't know that 'publish' was an event you could connect to through the Dojo object. That really makes things interesting. Tony, thanks for the snippet. Any chance you can give some background to what you’re doing here. I’m especially intrigued with the:
