Hi,
I was just about to reply and say I solved it. Missing slash in the
location.href. The following works:
<input type="button" id="cancelButton" value="Cancel"
onclick="location.href='/Administration';"/>
thanks for your help.

I'm not sure but I thinks it's a similar problem. It looks like
Administration is interpreted as the context.
If you want to cancel the page it's easier to use the t5Component Button
component.
Add t5Component jar to you project (see
http://code.google.com/p/tapestry5-components/) and add this to
the .tml:
<button t:type="t5components/Button" type="button"
t:event="cancel">Cancel</button>
And add an event handler in your page:
protected Object onCancel()
{
return Administration.class; // The Page to redirect to
}

Thanks for the fast reply Martijn; that fixed the GIF asset.
However, I am still having problems with the Cancel button. I can
reference the Administration page as an asset, but obviously it then
does not get processed by Tapestry.
Thoughts, anyone?
<input type="button" id="cancelButton" value="Cancel"
onclick="location.href='Administration';"/>
