Simple test using WSDataSource and SmartClientOperations.wsdl:
	The Developer Console WSRequest output with current smartgwt.jar reads:
	data element is empty !
While the Developer Console WSRequest output with smartgwt.jar from svn 827 (SmartClient 7.0RC3) reads:
	data element properly filled.
SmartClientOperations.wsdl is taken from the current svn.
The problem lays at the end of DataSource.js xmlSerializeFields fuction:
	Changing:
if (!flatData && !isc.isA.Schema(this)) {
to:
if (!flatData) {
resolves this issue (at least for me) and I am a little bored patching it every svn update I did.
Should I create new issue at the smartgwt project hosting ?
Just want to fix it permanently.

The problem lays at the end of DataSource.js xmlSerializeFields fuction:
Code:
	
	        // if there's any data left, tack them on the end, but *not* if this DataSource came
        // form XML Schema, in which case the extra data is sure to be invalid
        if (!flatData && !isc.isA.Schema(this)) {
            for (var fieldName in data) {
                output.append(this.xmlSerializeField(fieldName, data[fieldName], flags, indent));
            }
        }
if (!flatData && !isc.isA.Schema(this)) {
to:
if (!flatData) {
