How to Handle if the result is empty with CQL filter in WMS requests
I have used CQL Filter with WMS Layer. If filter not satisfies with given value getting empty tiles. In this case I want to show result is empty. How to handle this.
For example: WMS layer is having attribute called STATE_NAME and its has value India. If we use CQL Filter has STATE_NAME= 'India' it is getting proper result. If we sent the CQL filter with value which does not contained in STATE_NAME it is showing empty result. i.e STATE_NAME= 'Indi' result is empty. when this kind of queries formed and sent to server , I want to display to end user result is empty message.
