RE: generates incorrect encoding?

[Martin van Dijken]

Hey Andreas,

I can't verify right now that the c taglib actually does what you say, for lack of 
time. I can confirm however that & signs should at all times be escaped in HTML, also 
when used in a href's. I've run into a similar problem with our product and had to 
look into it myself.

If nobody responds to this, post to the dev-list or directly place a bug in bugzilla.

Grtz,

Martin
