& character and url-generator

Alessandro Vernet wrote

Hi Boon,

You should not need to unescape "&". I have just tried to run the
attached XPL in the XPL sandbox. It calls the URL generator for a URL
that just displays the query string, and it works as expected.

Neil,

I am not sure to understand what the problem is. Could you maybe  
attach an example of XPL that runs in the XPL sandbox and that shows  
the issue you are having?
