  • When items in select box, list box are selected and radio button, check boxes are selected then their labels will not go to server as request parameter values. The values of their respective value attributes will go to server as request parameter values.
  • When check box is not selected, no item of list box is selected then they will not send their request parameters to server. So the related setxxx () methods in form bean class will be not be executed. Whereas the remaining form components send default values (empty Strings) as request parameter values even though they are not filled up with values or not selected.
