HTML Data

I am using the HelloWorld example. I modified it so that the "message" string in the HashTable contains HTML (instead of "Hello" and "World", I put "<h1>Hello<br>World</h1>). It does not seem to encode HTML. Instead, it seems to escape the special characters to that the screen actually writes out the HTML. Is there any way to return HTML and have it render as HTML and not text? I also tried to use escape characters for "<" and ">", but it also didn't work.

Rendering HTML in the cells should be enabled by the page through a call to setPushedHtmlEnabled on the involved Table object.
