[Users] Accessing Layer Metadata

[Andreas Hocevar]

Hi,

you have to apply the filter *before* your tree loaders access the store. The loaders don't listen to filter changes.

I've managed to list all the layers in an ExtJS gridPanel, but have not been able to successfully apply a filter to the store - this, for example, seems to have no effect on the list, which displays all my GeoServer layers:
>> store.filter([    {
