Problem with setHref() encoding

Hello,

I have a problem with the setHref() method in a HTMLAnchorElement class.

In my html source, I have the following case:
<a href="Event.event?param1=value1">...</a>

In my (Barracuda) renderer, I would like to add a parameter to the 
query string of this link (by appending "&param2=value2), but all I 
get is <a href="Event.event?param1=value1&amp;param2=value2">...</a>.

Is there a way to disable this encoding?

Thanks,
