result view doesnt get updated

hello experts

I have created a custom bsp component with search result view. when i define search criteria and click on the search button i could retrieve the search result but the problem is when i modify the search criteria and click the search button the result doesnt get updated according to the new search criteria and the previous result appears instead. An information message is also thrown up giving the transaction SAAB error that a  BSP_WD_EXCEPTION_DISPLAY check point group should be activated

plz help

regards
