hi, i found the root cause. whenever a search is performed they have tried to fetch the value of one model bean and set it into another model bean. During page refresh the value is fetched in the first model bean but the Object of the model bean were they are trying to set the value is null. Now i placed an if condition tat checks if the Model bean object were they are trying to set the value is null and if it is null create a new Model Bean object. Now its working fine.
