Hi Nico!
Only certain types of dataypes can be filtered in in a fetch using attribute-filter. See http://ez.no/ez_publish/documentation/reference/data_fetching/content/list

I really don't know if this will work, but if the attribute is of datatype ezstring (which it's probably not) you could try

'attribute_filter', array( array( 'your_class/aktuelles', 
                                               '>', 
                                               '0' ) )

It's good practice to also filter on class when filtering on attribute.

If this is not working, my only solution would be to fetch all nodes and make a counter in the loop and test the aktuelles-attribute for content.

{let counter=0}
{section loop=$nodes}
{section show=and($counter|lt(5), count_chars(trim($:item.data_map.aktuelles.data_text))|gt(0))}
  {set counter=$counter+1}
  <a href={concat("/content/view/full/",$:item.node_id)|ezurl}>{$:item.data_map.aktuelles.data_text}</a><br /><br />
 {/section}
{/section}
{/let}

This is a ugly hack and will continue to iterate the $node-loop even when 5 items has been written.

Hope someone comes up with a better solution.

Hi!

I have a small note about your syntax. I would do something like this:

{let nodes=fetch( 'content', 'list', hash( 'parent_node_id', 2,
                                           'limit', 5, 
                                           'sort_by', array( 'published', false() )) ) }

{section var=node loop=$nodes}
{section show=$node.object.data_map.aktuelles.has_content}
<a href={$node.url_alias|ezurl}>{$node.object.data_map.aktuelles.content}</a><br /><br />
{/section}
{/section}

Notice the use of var in the section. This is much nicer, because namespaces can get very confusing if you have several loops inside eachother.

Also the $node.url_alias makes the nice urls, and not the system urls ("/my_funkystuff" as opposed to "content/view/213")

Yeah. The 'list' (and node 2 (the root node)) was just there because i used that in my test. Sorry about that.

By the way should fetch only the classes that has the "aktuelles" attribute. Like this:

{let nodes=fetch( 'content', 'tree', hash( 'parent_node_id', 108,
                                           'limit', 10, 
                                           'class_filter_type',  'include',
                                           'class_filter_array', array( 'YOURCLASSHERE' ) ),
                                           'sort_by', array( 'published', false() )) ) }

{section var=node loop=$nodes}
{section show=$node.object.data_map.aktuelles.has_content}
<a href={$node.url_alias|ezurl}>{$node.object.data_map.aktuelles.content}</a><br /><br />
{/section}
{/section}

Where YOURCLASS here is the name of the class (eg article).
