Re: [Dynapi-Help] Another newbie ? re: setURL() in IE

[Mark P. <mar...@hi...>]

Sam,

I have encountered this error, but it dissappeared as I continued development on my
widget.
I think the solution is to not use the setURL method until the layer has been added to the
DynAPI.document.
By swopping the last 2 lines of your code, all should be OK.

e.g

DynAPI.onLoad = function ( )
{
  testlayer = new DynLayer(null,100,100,143,16,"#ffffff");
  DynAPI.document.addChild(testlayer);
  testlayer.setURL("ext.html");
}

Good Look

Mark
