[TYPO3-project-formidable] renderlet:TAB & renderlet:TABPANEL

[news at das-rad-ruft.de]

Hi @all,

first formidable is an incredible framework and many
thanks. 

I'm using the version 2.0.300 and would like to use
tabs in a form. I've searched but found no example - is there a small
example for the definition of tabpanel and tab? In the changelog is a link
to an external website with a demo. Is the tabpanel the root element for
the tabs? 
I've tried something like
<renderlet:TABPANEL
name="panel">
<childs>
 
<renderlet:TAB name="tab1"/>
</childs>
</renderlet:TABPANEL>
gives an error in the apache log
(missing object for getter of html id)

TIA, dietmar
