[Chameleon] FILTER on a WMS layer

[Suddaby, Rod]

Hi All:

Is it possible to set a filter on a WMS layer? For example, I have the map
file used to initialize chameleon:

...
LAYER
  NAME FireWeather
  CONNECTIONTYPE WMS
  ...
END
...

and within the initializing .phtml file I do something like:

...
$oLayer = getLayerByName("FireWeather");
$oLayer->setFilter("filter_string");
$oApp->CWCExecute();

This does not do any filtering and I'm starting to suspect that this is not
possible with WMS layers. Any thoughts?

Thanks,
Rod.
