I'm implementing a template for a summary view of a Article object, which can have various kinds of related objects, but I only want to show one related objects of type Image.
I was surprised that class_filter_type can not be used with fetch(content, related_objects).

This works:

{def $img=false()}
{section loop=fetch(content, related_objects, hash( object_id, $article.object.id))}
	{section-exclude match=true()}
	{section-include match=$:item.class_name|eq('Image')}
	{run-once}
		{set $img=$:item}
	{/run-once}
{/section}

But it seems rather cumbersome. Is there an easier way to do this?

I found a simpler way:

{foreach $article.object.related_contentobject_array as $object}
{if $object.class_name|eq('Image')}
{def $img=$object}
{break}
{/if}
{/foreach}

I was a bit confused by the old-style and new-style syntax. Many examples use {section}, {default} and {let}, which seem all be deprecated. Being a PHP programmer, the new syntax looks a lot more familiar :)
