Wrong data in web app

Hi,
I have a small issue where sometimes when I start the web app I get a message on the gauges saying "You called the draw() method with the wrong type of data rather than a Data Table or Data View.
If I refresh the page (sometimes a few times) it sorts itself out.

I have attached the program but not sure it will help as it does not happen every time.

Thanks for the report. I think this happens only when you use multiple charts/gauges in a Web Developer app. I will investigate and try to provide a fix.
