Alfresco Explorer blocks properties when I change it?

[spilby]

I have a problem after using the Alfresco Explorer.

I have created a java webscript to create nodes and modify properties, into a transaction, oks? All works fine when I use the webscript. I create folders, subfolders, modify the properties, all ok.

But then, I do the following… I go to the Alfresco Explorer. Find one of the folders and edit the properties, modify something and save.

After I do this, when I use my webscript and try to change a property of one of the nodes that I changed before with the Alfresco Explorer, a exception is thrown: "ConcurrencyFailureException: Failed to update node". And I can't change or add properties on this node. Only if I restart the server I can update with my webscript the node again and all works fine another time.

First I thank that was a problem in my code, but if so, it would never works. Or it doesn't works after the restart. But no, the code works always if I don't use the Alfresco Explorer, and works again if I restart the tomcat server where alfresco runs.

Are there a problem with the Alfresco Explorer that blocks the properties of the nodes when someone change it? What might be the problem? I'm using Alfresco Enterprise v4.1.6.

Thanks!

I try to implement this solutions. But when create the node, give me this error:

org.springframework.dao.DataIntegrityViolationException: Detected stale node entry: NodeVersionKey [nodeId=260884, version=1558] (now [NodeVersionKey [nodeId=260884, version=1559]])

This is my code:

public NodeRef transaccionCreateNode(final NodeRef parent, final Map<QName, Serializable> properties, final String name, final QName tipus) throws Exception {
NodeRef nodeRef = null;
       try {
          RetryingTransactionCallback<Object> txnWork = new RetryingTransactionCallback<Object>()
           {
               public Object execute() throws Exception
               {
                  NodeRef nodeRef = createNode(parent, properties, name, QName.createQName(Constants.modelClassificacioNS, Constants.tipusNodeClassificacio));
                  
                   return nodeRef; 
               }
           };
           TransactionService transactionService = serviceRegistry.getTransactionService();
           nodeRef = (NodeRef)transactionService.getRetryingTransactionHelper().doInTransaction(txnWork, true);
       } catch(Throwable e) {
         logger.error("transaccionCreateNode - ERROR: " + e);
         throw new Exception(e);
      }
      
        return nodeRef;
}

Where I had before:

public NodeRef transaccionCreateNode(final NodeRef parent, final Map<QName, Serializable> properties, final String name, final QName tipus) throws Exception {
NodeRef nodeRef = null;
       
       UserTransaction trx = serviceRegistry.getTransactionService().getUserTransaction();
      
       try {
         trx.begin();
         nodeRef = this.createNode(parent, properties, name QName.createQName(Constants.modelClassificacioNS, Constants.tipusNodeClassificacio));
         trx.commit();
      } catch(Throwable e) {
         trx.rollback();
         logger.error("transaccionCreateNode - ERROR: " + e);
         throw new Exception(e);
      }   
        
       return nodeRef;
}

In the code of DataIntegrityViolationException I found this about this message:

// We found properties associated with a different node ID and version
            invalidateNodeCaches(nodeId);
            throw new DataIntegrityViolationException(
                    "Detected stale node entry: " + nodeVersionKey +
                    " (now " + propsRawByNodeVersionKey.keySet() + ")");

I have properties with a different node Id and version when I create a node and use getRetryingTransactionHelper? \ You know where is the problem? I'm not, and I'm sorry to ask another time, but I need to find the solution. Thanks again for your time.

Any suggestions about this problem? Someone meets with this error? Or knows why happens. Thanks again.

I am trying to add a heading between the list of custom-properties that appear under Advanced Search panel in Alfresco Explorer. Let me know how can I add a heading or a separator between the list of custom properties.

<code> <property-sheet> or <separator> <code> tag is not reflecting in the Advanced Search UI
