Well thanks for the suggestion, but yesterday itself I had solved this
problem by myself.

if you are using the latest beta build (6 as of now) you need to add
some kind of binding prefix in front of the value attributes in your
bindings. Your components would in turn look like:
           <component id="users" type="For">
                       <binding name="source" value="ognl:users"/>
                       <binding name="value" value="ognl:user "/>
                       <binding name="element" value="literal:tr"/>
           </component>
           <component id="username" type="Insert">
                       <binding name="value" value="ognl:user.username"/>
           </component>

Hope this helps.
