As an example of quirky behavior, execute_script() imposes a fairly small (and undocumented) limit on the size of the executed code string. So, although the call can be used to transfer data (eg, as JSON), any significant amount of data will require multiple calls.

What is the limit? I was relying on this to push (sizeable) model data into a silverlight plugin in the WebDialog. I had assumed I needed to chunk, but it would really help to know what that limit is, so I can chunk to that size.

Thanks!
