[opencms-dev] contenload & include

[Ruben Malchow]

hi christian,

well ... the "template" property is not set at all ... now you speak of 
it, can anyone describe the reasoning behind these two properties?

anyway, what i do now is this (and it works like a charm):

	<cms:contentload
		collector="allInFolderPriorityTitle"
		param="/path/|999">

		<c:set
			var="file">
			<cms:contentshow element="%(opencms.filename)"/>
		</c:set>

		<c:set var="template">
			<cms:property
			name="template-elements" file="${file}"/>
		</c:set>

		<cms:include page="${template}">
			<cms:param
				name="file">
				<c:out value="${file}"/>
			</cms:param>
			<!--- ... other params -->
		</cms:include>

	</cms:contentload>

so i don't include the content, but the template, and pass the content 
as a parameter. now, this has one drawback, which is that the template 
will have to know how use the parameter ...

anyway, i think also there might have been an JSTL / EL vs OCMS macro 
issue ...
