Hi Tom,

Thanks for the tip. This is an easy oversight when you are coding with the Prototype library. I had something like this:

document.forms[0].writeAttribute(”attr”,”val”)

which should have been:

$(document.forms[0]).writeAttribute(”attr”,”val”)

Oh BTW, this is do to the fact that setStyle() is a prototype extended method. $() extends the element. Since you used a ‘native’ element creation method you did not get the extended methods. Seems like Builder would return an extended node though. No answer for the discrepancies between browsers though. Additionally you could call:

Element.extend(this.Message);

before using setStyle()

Thanks a lot, it also needs be done when using Builder:

this._dialog = $(Builder.node(’div’));

strange.
