processLegendTemplate -> leg_group_html returns "" ?

[Clarence Ng]

Hi List,

Currently using PHPMapscript/Chameleon, I couldn't get processLegendTemplate
to return anything whenever i add the pair of leg_group_html tags into my
template document. Without the leg_group_html it works fine. It would still
work if i put the leg_group_html tags after leg_layer_html and have no
content between leg_group_html. Having any content between leg_group_html or
by putting the pair of tags before leg_layer_html will result in
processLegendTemplate returning nothing.

I also tried assigning metadata to the layers for processing, but
oMap->getAllGroupNames() returns nothing. The GetCapabilities request are
correctly showing these WMS layers under different groups.

Maybe someone can point me to the right direction? Any help will be greatly
appreciated.
