Posting Hierarchical XML

[ajjain]

Hi Isomorphic,

I wish to submit a nested custom XML back to the server using DataSource.

Fetched XML Format:

<response>
   <data>
      <record>
         <field1>Field1 Value</field1>
         <group>
            <field2>Field2 Value</field2>
         </group>
      </record>
    </data>
</response>

This is not the plain name-value mapping instead has an one more level of nesting. I was able to fetch the data correctly into the form used valueXpath with the datasource field. While saving I expected datasource to update the XML using XPATH attribute but it doesn't.
XML format while saving data was :

<request>
    <data>
    	<field2>Updated Field2 value</field2>
    	<field1>Updated Field1 value</field1>
    	<group>
    		<field2>Field2 Value</field2>
    	</group>
    </data>
</request>

Following is the code which I am using

		isc.DataSource.create({
			ID:"contacts",
			dataFormat:"xml",
			recordXPath:"/response/data/record",
			dataURL:"http://localhost:8011/test/data",
			fields:[
				{name:"field1"},
				{name:"field2", valueXPath:"group/field2"},
			],
			transformRequest : function (dsRequest) 
			{
				alert(this.xmlSerialize(dsRequest));
				var params = {"data":dsRequest.data};
				return this.xmlSerialize(params, null, null, "request");
			},
			operationBindings:[
				{
					operationType:"update", dataProtocol: "postMessage",
					dataURL:"http://localhost:8011/test/data"
				}
			]
		});

		isc.DynamicForm.create({
			ID: "exampleForm",
			width: 250,
			dataSource: contacts,
			 autoFetchData: true

		});

		isc.IButton.create({
			left:0, top:40, width:50,
			title:"Save",
			click: function () {
				exampleForm.saveData();
			}
		});

Please tell me how can I update the request XML correctly. FYI, I am not using smartclient server.

REF: DataSource Field Reference Doc for valueXpath says:
When you are saving data, the inbound DSRequest values, available as a Java Map, will use just dataSource field names as Map keys, not the valueXPath used to derive them. However, to achieve bidirectional valueXPath binding, you can use the server-side method dataSource.setProperties() to use the valueXPath when setting properties on your server object model.

I want to send the XML in a proper format to server so need to convert the XML at client side only. I tried using XMLTools api too but that too didn't helped me. I am blocked on this issue please lemme know the workaround or solution for this ASAP.
