/**
*
*
* The tabbedpanel widget is primarily an AJAX component, where each tab can
* either be local content or remote content.
*
*
* If the useSelectedTabCookie attribute is set to true, the id of the selected
* tab is saved in a cookie on activation. When coming back to this view, the
* cookie is read and the tab will be activated again, unless an actual value
* for the selectedTab attribute is specified.
*
*
*
*
* Examples
*
*
*
*
*
* <sj:tabbedpanel id="mytabs" animate="true" collapsible="true" useSelectedTabCookie="true">
* <sj:tab id="tab1" target="tone" label="Tab One"/>
* <sj:tab id="tab2" target="ttwo" label="Tab Two"/>
* <sj:tab id="tab3" target="tthree" label="Tab Three"/>
* <div id="tone"> Test 1 </div>
* <div id="ttwo"> Test 2 </div>
* <div id="tthree"> Test 3 </div>
