[Users] help: WMSCapabilitiesStore and grid update

[Amini, Manouchehr]

 Hi Seth
Thank you for your reply. 
I checked the function in the FF and It shows an empty grid. I could not figure out what is wrong with it. 

In fact I use exactly the same url to retrieve the layers from a specific namespace every time I fire the function, but I expect different results. As I change the layers of that namespace (add or remove layers). I also tried to create store in a different function, it didn't work. 

Any further suggestion?
Thanks
Manouchehr

Hi,

Check with FIreBug or Fiddler that you are calling a different URL each 
time - and that results should be different.
If this is the case, are you refreshing your grid?

I have working code to update a store's URL and parameters as follows:

         this.store.proxy.setUrl(url, true);

         if (paramsObj) {
             this.store.reload({
                 params: paramsObj
             });
         }

Regards,

Seth
