JSF Component & Render

echohfut

when using JSF, some scenarios are difficult to deal with.
e.g. 1. multi rows raido buttons in dataTable
     2. multi columns radio buttons in dataTable
     The radio buttons don't fall in the one radio group, so they don't behave as one radio group

Solution: create customize component
     step1, inherit and implement component class
           add one overrideName field, so we can override the radio names generated by radio button. In this way, multi-row or column radios are considered in one radio group
     step2, inherit and implement render class
         override Decode(apply request phase, retrive the value from request obj and apply to component)
         override Encode(render response phase)

     step3, customize tag lib
