I wanted to know how ResultSet will figure out if there is a change in the criteria.
When i am creating a new instance of ResultSet with some data and setting it to the ListGrid ,the Listgrid always assumes that there is a change in the criteria and the existing data is wiped out by call to InvalidateCache and new data is cached from position 0.
Is there anyway that i can hint ResultSet to insert the data received from the server to cache from a specified position (eg : startRow)
To Elaborate on this,
Following logs
Above log gives the information regarding the dropping of cache on change of criteria.However i am not making any criteria changes as you can see that in the following code
