<DIV></DIV>If you modify the layer visibility, using serverside code, it will
not work correctly with the AJAX viewer.<BR>The problem is that the AJAX client
has a small cache of visible layers, and calling map.refresh() on the client
does not invalidate this cache.<BR><BR>The symptoms will be that no tooltip is
displayed for the layer, and the layer never shows up in the legend.<BR>I've
posted this bug on the mapguide-internals list, and a workaround.<BR><BR><PRE class=moz-signature cols="72">Regards. Kenneth, GEOGRAF A/S
