Get the value of a DS field bounded to XML

[scurvo]

Hi all,

I'm using SmartGwt v2.2.

My problem is i have a Grid with 2 Fields, one should have a Tree, and the other one the values of each tree node.
I am using a DS to extract those values from a XML. Problem is i can't get the values out of the DS. Is there a way to get the value of a given field?

I tried statisticsDS.getField("dataSourcesIdExtracted"), but from here i can't get the field's value only it's name.

Anyone can help?

My DS code is:

public RepoxStatisticsDS() {

setID("statisticsList");
setRecordXPath("/repox-statistics");
DataSourceIntegerField pkField = new DataSourceIntegerField("itemID");
pkField.setHidden(true);
pkField.setPrimaryKey(true);

DataSourceTextField nameField = new DataSourceTextField("dataSourcesIdExtracted", "dataSourcesIdExtracted", 128, true);
DataSourceTextField dataSourcesIdGeneratedField = new DataSourceTextField("dataSourcesIdGenerated", "dataSourcesIdGenerated", 128, true);
DataSourceTextField recordsField = new DataSourceTextField("records", "Records", 128, true);
recordsField.setValueXPath("countriesRecords/countryRecords/records");

setFields(pkField, nameField, dataSourcesIdGeneratedField, recordsField);

setDataURL("data/repoxStatistics.xml");
setClientOnly(true);
}

You can't get value from DataSource directly. DS is a kind of data stream definition.
You may want to attach DS to the ListGrid or DynamicForm:
listGrid.setDataSource(ds);
listGrid.fetchData();
or fetch data and get response:
ds.fetchDate(criteria, callback)

And is there a way to retrieve a given XML field value into a ListGRid RECORD for example?

listGrid.getRecord(0).getAttribute("dataSourcesIdExtracted")
