panelSet inside a tab

I'm trying to display a panelSet inside a tab. Is this possible?

<b:tabBox>
   <b:tab label="2001" padding="5px 10px" icon="icon-film">
       <b:panelSet rows="100px *" columns="300px *">
           <b:panel backgroundColor="#82AADF" />
           <b:panel backgroundColor="#A4C1E7" />
           <b:panel backgroundColor="#C6D8F0" />
           <b:panel backgroundColor="#E7EFF9" />
       </b:panelSet>
   </b:tab>
   <b:tab label="Seven Samurai" padding="5px 10px" icon="icon-film">
      <h2>The Seven Samurai (Shichinin no samurai, 1954)</h2>
      <p>A movie by Akira Kurosawa starring Takashi Shimura and Toshiro Mifune.</p>
   </b:tab>
</b:tabBox>

Thanks in advance.

yes, it is possible. if

yes, it is possible. if you're not seeing the panels, try setting the height attribute of the tabBox value of 100%. Also, try setting the fullScreen attribute of panelSet to value of true.
