[Users] GeoExt.data.WMSCapabilitiesStore question

[geographika]

Hi,

Do you definitely have a "name" property on your records (I think this 
is a default but worth checking)? You have a "title" defined in your 
grid columns, so maybe try filtering with this as a test.
Try removing the autoLoad: true, and loading the store manually with 
Temp_grid.load() then apply the filter.
Also I have not done this myself with the WMS store so keep in mind it 
may not be the best approach.

Regards,

Seth
