Child association and web client

skank — Mon, 26 Jul 2010 11:50:50 GMT

Hello,first, I apologize for my bad English I have created a custom model with a child association between two documents : <types> <type name="az:doc"> <parent>cm:content</parent> <properties> <property name="az:vers

You should see your child associations on the property details for an instance of az:doc but you will not see instances of az:model from a web client browse space view. You'd have to do a customization to get that to work. In the web client, only the child associations of the given cm:folder (or its subtype) are displayed in the list of documents.

Thank you for your reply. I've done a customization like you said : I've overrided the BrowseBean, and now I can see my az:model, next to my az:doc.

Hi skank,

I'm interested on how you've overrided the BrowseBean.
Could you give your config as an example ?

I'm trying to do the same thing for a day, and I'm in despair :?

Thanks
Laurent

No problem

Here is my faces-config-custom.xml (in WEB-INF) :

I've copied the source code of BrwoseBean in my CustomBrowseBean. Then, I've added this in the queryBrowseNodes method (line 930) :

         if (parentNodeId == null)
         {
            // no specific parent node specified - use the root node

         }
         else
         {
            // build a NodeRef for the specified Id and our store
            parentRef = new NodeRef(Repository.getStoreRef(), parentNodeId);
         }

         this.containerNodes = new ArrayList<Node>(children.size());
         this.contentNodes = new ArrayList<Node>(children.size());

         // in case of dynamic config, only lookup once
         Set<NodeEventListener> nodeEventListeners = getNodeEventListeners();

         for (FileInfo fileInfo : children)
         {
            // create our Node representation from the NodeRef
            NodeRef nodeRef = fileInfo.getNodeRef();

            // find it's type so we can see if it's a node we are interested in
            QName type = this.getNodeService().getType(nodeRef);

            if (typeDef != null)

Thank you for your quick answer.

Unfortunately, that does not resolve my problem…
