[opencms-dev] contenload & include

[Ruben Malchow]

and another one ... any way to get values from the content into the 
collector and param attributes?


this doesn't do the trick:

	<cms:contentload
		collector="singleFile"
		param="%(opencms.filename)">
		
		<cms:contentloop element="main_area_component">

			<c:set var="collector">
				<cms:contentshow
					element="collector"/>
			</c:set>
			<c:set var="param">
				<cms:contentshow
					element="param"/>
			</c:set>
	
			<cms:contentload
				collector="${collector}" 	
				param="${param}">
		</cms:contentloop>
	</cms:contentload>
