[TYPO3-project-formidable] Render another extension inside Formidable

Sat May 17 10:40:19 CEST 2008

Hello,
is it possible to render in Formidable the content generated by another 
extension?

I tried this:
-----------------------------------------------------------------------
<renderlet:BOX name="tagcloud" mode="inline">
     <html>
	<userobj>
		<ts>
			<![CDATA[
			10 < plugin.tx_vgetagcloud_pi1
			10.cloud {
				referenceTable = tx_iangallery_gallery
				referenceFields = title, description, tags
				maxWords = 20
			}
			]]>
		</ts>
	</userobj>
     </html>
</renderlet:BOX>
-----------------------------------------------------------------------
but it displays nothing.

If I put the plugin into the page with the backend, it works.

Am I missing something?
Or it simply can't work?

Thanks in advance for your time!
