The Surf web tier has no concept of nodes, aspects, properties, etc. - you'll need to use a repository webscript, e.g.

remote.call("/api/metadata?nodeRef=" + nodeRef)‍

That will return a JSON structure with the node's properties.

Thanks,
Mike

Hi Mike,
Thanks for the quick reply.
As per your suggestion I am using

remote.call("/api/metadata?nodeRef=" + nodeRef)‍

in the task-lits-min.js. But I am getting "remote is not defined" error.
Please help!!

Thanks
Sanjay!!

You were trying with browser-based JavaScript? No wonder it didn't work! The "remote" object is part of the Surf API - i.e. it needs to run on the web server.

If you want this to be requested from the web browser, you'll need to use an AJAX request. Have a look at Alfresco.util.Ajax.jsonGet in alfresco.js

Hi Mike,
Regarding the problem that I am facing…

I looked at the jsonGet in alfresco.js. In my javascript i am calling the jsonGet method and I am getting successful result. In the fire bug I can see the response and the data. It shows me folderName as well. But I need to extract the values from the response.
I tried to use myObject.getData("properties")["{http://www.alfresco.org/model/content/1.0}title"]. But I am getting error on getData method.
Here is code snippet

    Alfresco.util.Ajax.jsonGet(
         {
            url: Alfresco.constants.PROXY_URI_RELATIVE + "api/metadata?nodeRef=" + nodeRefContext ,
            successCallback:
            {
               fn: function(response)
               {
                  if (response.json)
                  {
                     var json=response.json;
                     json.getData("properties")["{http://www.alfresco.org/model/content/1.0}title"];
                  }
               },
               scope: this
           },
      failureCallback:
           {
               fn: function(response)
               {
                  Alfresco.util.PopupManager.displayPrompt(
                  {
                     failureMessage: this.msg("message.failure")
                  });
               },
               scope: this
            }
         });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Also how do I return the results of a ajax request?

Please help!!

Thanks
sanjay!!

response.json.properties["{http://www.alfresco.org/model/content/1.0}title"]‍

If you prefer you can add &shortQNames=true to the URL so then you could get the title from

response.json.properties["cm:title"]‍

Thanks,
Mike

Mike,
Great Stuff!! It worked!! You Rock!!
One quick question.
How do i get the details in the caller method? I am getting the title as undefined. But if I print it inside method it prints the value.
here is the code snippet.

var title;
    Alfresco.util.Ajax.jsonGet(
         {
            url: Alfresco.constants.PROXY_URI_RELATIVE + "api/metadata?nodeRef=" + nodeRefContext + "&shortQNames=true" ,
            successCallback:
            {
               fn: function(response)
               {
                  if (response.json)
                  {
                     title=response.json.properties["cm:title"];
           console.log(title);
        }
               },
               scope: this
           },
      failureCallback:
           {
               fn: function(response)
               {
                  Alfresco.util.PopupManager.displayPrompt(
                  {
                     failureMessage: this.msg("message.failure")
                  });
               },
               scope: this
            }
         });
    console.log("title "+this.title);‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Please help!!

Thanks

It's an asynchronous request with a callback function. Your console.log command is executing before the response has been parsed.

If none of that makes sense, you need to do some reading up on JavaScript and AJAX.

Thanks Mike!!!
Now I can show Site Name, Initiator, Owner, and Folder Name on my tasks page.
I also want to show the file name which is part of the workflow.
I have bpm_package. How can I get the file name from this?

Please help!!
