Removing association -> Integrity violation

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

On a type I have the association

<aspect name="tk:relatedDocuments">
                    <title>Related documents</title> 
                    <associations>
                                  <association name="tk:relateByAssocation">
                                               <title>Associated documents</title>
                                               <target>
                                                       <class>ver:version</class>
                                                       <mandatory>false</mandatory>
                                                       <many>true</many>
                                               </target>
                                  </association>
                    </associations>
</aspect>

Essentially this is only used for creating references between content.

The association is populated by a search and when a new search is conducted the old associations should be replaced with new ones. And this is resulting in a integrity violation:
The association source multiplicity has been violated:
   Target Node: workspace://lightWeightVersionStore/dba1ad09-a10f-11dd-9061-815ef8c051c2
   Association: Association[ class=ClassDef[name={http://www.jonkoping.se/alfresco/model/tk}relatedDocuments], name={http://www.jonkoping.se/alfresco/model/tk}relateByAssocation, target class={http://www.alfresco.org/model/content/1.0}content, source role=null, target role=null]
   Required source Multiplicity: 1..1
   Actual source Multiplicity: 0

The code to delete the association is as follows:

nodeService.removeAssociation(a.getSourceRef(), a.getTargetRef(), JkpTkModel.ASSOC_RELATE_BY);‍

where "a" is the association.

The same error occurs if I try to delete the association in the contents property sheet so my guess it is not in the code but in the model…

Of course the solution was a simple error in the model. The association source needs to have property mandatory=false (as below)!

    <aspect name="tk:relatedDocuments">
                        <title>Related documents</title>
                        <associations>
                                      <association name="tk:relateByAssocation">
                                                   <title>Associated documents</title>
                                                   <source>
                                                          <mandatory>false</mandatory>
                                                   </source>
                                                   <target>
                                                           <class>ver:version</class>
                                                           <mandatory>false</mandatory>
                                                           <many>true</many>
                                                   </target>
                                      </association>
                        </associations>
