Hi Tucker,

I just came across this error again when the code is trying to add a 
property for an event handler.

<canvas width="800" height="800">

   <dataset name="myData" src="http://..."
        ondata="trace('got data ' + this.serialize())"
        type="http"/>

   <handler name="oninit">
     myData.doRequest();
   </handler>

</canvas>




ReferenceError: Error #1056: Cannot create property 
$lzc$handle_ondata$$data$2D6$2Elzx_8_21_$m2 on .LzDataset.

Any ideas on the cause of this error?

Thanks!
