dynamic constraint check if "not set"

 Hi,

I want to check, if in a profile property at least one Doors Requirement is attached to a HE.

my script is reporting everytime an error (even if something is attached):

    -- util to check comment   
def:
    check(comment:String, message:String):String
    =    if comment.oclIsUndefined() then
            message
        else
            if comment.trim()='' then
                message
            else
                ''
            endif
        endif
inv:
let
    safetyCriterion:String = self.getProfilePropertyValue('user_safety_criterion' )->first().oclAsType(String),

    val1:String= check(safetyCriterion, 'safetyCriterion')
    
in
    if not self.integrityLevel.oclIsUndefined() then
        val1=''
    else
        true
    endif

Hi,

I think I solved it.

inv: not self.getProfilePropertyValue('user_xc_da_safety_criterion' )->first().oclIsUndefined()
