creating association

[jeyaa]

Hi all,

I have a model like

<type name="custom:customType">
         <title>custom Root Content Type</title>
         <parent>cm:content</parent>
         <associations>
            <child-association name="custom:myAssoc">
               <source>
                  <mandatory>false</mandatory>
                  <many>true</many>
               </source>
               <target>
                  <class>custom:comments</class>
                  <mandatory>false</mandatory>
                  <many>true</many>
               </target>
            </child-association>
         </associations>
         <mandatory-aspects>
            <aspect>cm:generalclassifiable</aspect>
            <aspect>custom:Info</aspect>
         </mandatory-aspects>
      </type>
                ……….
                ………..
               <type name="custom:comments">
         <title>Custom comment Type</title>
         <parent>custom:customType</parent>
         <mandatory-aspects>
            <aspect>custom:commentable</aspect>
         </mandatory-aspects>
      </type>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Here is my aspect…

<aspect name="custom:commentable">
         <title>Custom commentable Aspect</title>
         <properties>
            <property name="custom:timeStamp">
               <type>d:datetime</type>
            </property>
            <property name="custom:commentAuthor">
               <type>d:text</type>
            </property>
            <property name="custom:commentType">
               <type>d:text</type>
               <mandatory>true</mandatory>
               <constraints>
                  <constraint ref="custom:commentTypeList" />
               </constraints>
            </property>
            <property name="custom:commentDescription">
               <type>d:text</type>
            </property>
         </properties>
      </aspect>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Now I have a content called "Comment_Content.txt" of type "custom:comments", and have another content called "CustomType_Content.txt". Now I need to make "Comment_Content.txt" associated to "CustomType_Content.txt". So did like this.

this.nodeService.createAssociation(customTypeNodeRef, commentNodeRef,  new Node(commentNodeRef).getType());‍

But it is showing exception. Here is the stack trace.

Is this the right way to create association?. Please suggest on this.

Hi Jeyaa,

This seems to be correct  , the only thing  "new Node(commentNodeRef).getType()" . Please check if this  is returning proper value.

Thanks,

[jeyaa]

Thanks Amita,

Yeah I have checked it out and the value am getting for 

new Node(commentNodeRef).getType()‍

The above code is returning

http://www.Custom.com/model/content/1.0}comments‍

Am wondering on the exception that is occurring

java.lang.IllegalArgumentException: Association {http://www.Custom.com/model/content/1.0}comments has not been defined in the data dictionary‍

Any idea on this.

Jeya

Hi Jeyaa,


The method has two parameters correct but the third one you have to  create  QName of association and provide that.
For example : you have to create object like QName.createQName("http://www.Custom.com/model/content/1.0", "custom:myAssoc");

so the  correct method should be  similar to below code:
this.nodeService.createAssociation(customTypeNodeRef, commentNodeRef, QName.createQName("http://www.Custom.com/model/content/1.0", "custom:myAssoc"));

Thanks,

[jeyaa]

Thanks Amita. This is working. I never checked the association name from my code. This was really helpful. Thanks once again.  And one question. I want the "Comment_Content" has to be deleted if the "Customtype_content"  is deleted. What shall suppose to do for that.

Hi Jeyaa,

Since you have  already used child association  , it is going to  delete  associated  nodes  also. So no additional configurations are required.


Thanks,

[jeyaa]

Amita,

But its not happening like that. If I delete the "CustomType_Content.txt" the associated comment file is not getting deleted. And also if I try to get the number of child associations for the "CustomType_Content.txt" like

Map childAssoc= new Node(customTypeNodeRef).getChildAssociations();‍

The childAssoc size is 0. But If try to get associations like this,

Map assoc = new Node(nodeRef).getAssociations();‍

now the assoc size is 1.

I think the following line did not made the "comment_content" child associated. So what may be the problem in here.

this.nodeService.createAssociation(customTypeNodeRef, commentNodeRef, QName.createQName("http://www.Custom.com/model/content/1.0", "custom:myAssoc"));‍

Regards,
Jeyaa

[amitabhandari1]

Hi Jeyaa,

Please use the below code:
Collection<ChildAssociationRef> childAssocRefs = nodeService.getChildAssocs(nodeRef);
          if (childRefs.size() != 0)
            {
               for (ChildAssociationRef ref : childRefs)
               {
                 System.out.println(ref.getChildRef());
                 System.out.println(nodeService.gteProperty(ref.getChildRef(), ContentModel.PROP_NAME));
                }
         }

Thanks,

[jeyaa]

Thanks,

I tried on the above code and the size of the collection is 0. What may be the problem?

[amitabhandari1]

Hi Jeyaa,

what   you are passing in the nodeRef.

Thanks,
