Hi Armin, I had read through that thread on the list, and am in the same spot Stephan got to with defGroupList not defined, and as I looked at resolving my issue, it seemed I was essentially going through the steps of completely reloading the map. That's when I got discouraged and thought I'd check with the list..I was hoping someone on the list had gotten all the way through to a solution they were happy with.
Of course it's my problem, and I have to solve it, I was just hoping someone might have a flash of insight :) My understanding of the legend code is rather muddled. thank for the pointer though, -Keith On 12/4/06, Armin Burger <[EMAIL PROTECTED]> wrote: > Keith > > try to use as a starting point this topic from the mailing list: > > http://www.mail-archive.com/[email protected]/msg00494.html > > There is an attached PHP script for adding layers dynamically and the > explanations for it is in a mail later in that posting.
