Hi, 

in a M2Doc report, I need a filter for an empty checklistitem which is a user defined PJExternalDocument. 

Something like 

{m:if user_graphics_for_conclusion ->isEmpty()}

Settings as followed in Image 1 and 2

Element Attributes:

Hi Lisa,

Normally you should be able to use "<> null" for "not set" elements, but you have a collection (multiple model elements, visible by "[]" in the attributes view), which is always there in AQL. To check if it contains anything, please use 

{ m:if object.user_graphics_for_conclusion->size() <> 0 }

Does that work for you?

Regards,

Nils
