XF 1.5 RM customFields in resource_list_item and resource_view_header

[Robert9]

For me it looks like that
customFields should be available in both templates,
but while i can use

<xen:foreach loop="$resource.customFields " key="$key" value="$val" >
<pre>{$key}: {xen:raw $val} </pre>
</xen:foreach>

in resource_view_header, i dont get a result in resource_list_item.

Where is my fault? May someone has an answer for this, please?
