<f:section name="Sidebar">
	<v:content.render column="0" as="sidebarContentElements">
		<f:if condition="{sidebarContentElements}">
			Content available.
			<f:for each="{sidebarContentElements}" as="sidebarContentElement">
				Each item.
				<f:format.raw>{sidebarContentElement}</f:format.raw>
			</f:for>
		</f:if>
	</v:content.render>
</f:section>

This is the output that gets rendered.

Content available. Each item. Each item. Each item.

The content element count is correct. (3 items) But no content element itself gets rendered.

Debugged view for the sidebar elements:

Extbase Variable Dump array(2 items) 0 => '' (0 chars) 1 => '' (0 chars) Extbase Variable Dump array(2 items) 0 => '' (0 chars) 1 => '' (0 chars)

And each element gives me:

Extbase Variable Dump '' (0 chars) Extbase Variable Dump '' (0 chars)
