I have a canvas diagram on an asp.net-page
I can save and load it in code.
But when use diagram.zoomToFit() once in script,  there after postback always failes, with the error below.
(the Page_Load doesn't get executed)

any idea what is wrong?

It's a bug in the server code expecting ZoomFactor to be integer. For the time being you could round it after calling zoomToFit:

diagram.zoomToFit();
diagram.setZoomFactor(Math.round(diagram.getZoomFactor()));

I hope that helps,
Stoyan
