[Zope] External Methods question

[Richard Sean Bowman]

hello,

I have read the External Methods reference located at
zope.org/Documentation/Reference/ExternalMethods, and I'm trying to get
the small playhouse example working.  However, after calling
/rsb/addPlayHouse?id=myHouse (successfully) and attempting to access
/rsb/myHouse/index_html, I get a "requested document does not exist"
error.  My code is exactly as in the ExternalMethods document.  

Any assistance would be greatly appreciated.

thanks,
Sean Bowman
