Hi Jeyaa,

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

Thanks,

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.

Regards,
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,

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,

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

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,

Thanks,

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

Hi Jeyaa,
