AW.Templates.Textarea - let's get started

Okay, so I really need a skinned textarea.... and I love all the events, etc. that comes with input boxes so.....

That means this will involve many people and plenty of time... since after-all we want it to be good enough that Alex can easily include it into the next release (hopefully soon.... next bug release?).

So, I started by taking the imagetext Template and UI and began to take out the native HTML for the input box, and replace it with the native textarea element... easier said than done but we'll see how we can do it.

First off, remember that input boxes maintain a value. Textarea's maintain an innerHTML-type value.... BUT you'll notive the startEditGecko has a line in it for e.value..... because e.innerHTML isn't updated from the AW.HTML.TEXTAREA until you finish editing the textarea or explicitly set it....

BUGS:
1) I had to explicitly fire the startEdit event in the controller.... how is this supposed to be fired?
2) Should we not use the AW.HTML.TEXTAREA and use a straight textarea dom object? The input boxes are created as node2 in the bottom of the Gecko start... but not in ie... don't know why.
3) ANY SUGGESTIONS WILL HELP!
4) ANY SUGGESTIONS WILL HELP!
5) I DON'T understand all about the models, controllers, panels, etc. etc.... but I'm learning.
