T5: How do I enable XHR?

["Partogi, Joshua" <Jo...@AIG.com>]

Dear all,

When I tried to return a Block component an exception occured with this
message:

A component event handler method returned the value
org.apache.tapestry.internal.structure.BlockImpl@4b1bcd. Return type
org.apache.tapestry.internal.structure.BlockImpl can not be handled.
Configured return types are java.lang.Class, java.lang.String, java.net.URL,
org.apache.tapestry.Link, org.apache.tapestry.StreamResponse,
org.apache.tapestry.runtime.Component. 

When I traced it with request.isXHR() it also returns false. Now how do I
enable XHR in T5 so that I can return a Block component? I tried it in IE6
and FF3 but none of them works. Could anyone give me an insights on this?

Thanks in advance
