Hi Guy, is it crashing or "not working"? If you still see the error messages, I suppose it isn't crashing?
It looks like either the svgPoint or the matrix isn't properly defined? Maybe check the input parameters to mapApp.prototype.calcCoord(evt,ctmNode). Maybe either "evt" or "ctmNode" is an empty reference. If you just want to calculate the transformations up to the element where the event occured, it is enough to just pass over the "evt" object, you may omit "ctmNode" in this case or set it to "undefined". The function that you mention works fine in my Opera installation, so I suspect there is something wrong with your code. Does it work in other implementations? Firefox, Batik, ASV6? with no error message?
