more help with neted json/grids

[merkelct]

So this is fairly simple I think and may have a quick fix for some one with a little more experience. I am trying to read this JSON output from service but I am having problems getting it to display in the grid

final Panel panel = new Panel();
panel.setBorder(false);
panel.setPaddings(15);

final HttpProxy dataProxy = new HttpProxy("xml.json");
final RecordDef recordDef = new RecordDef(new FieldDef[]{
new IntegerFieldDef("iwfs:OBJECTID", "iwfs:OBJECTID"),
new StringFieldDef("iwfs:TITLE", "iwfs:TITLE"),
//new IntegerFieldDef("area", "area"),
//new IntegerFieldDef("population", "population"),
});
JsonReader reader = new JsonReader(recordDef);
reader.setRoot("gml:featureMember.iwfs:DDMS_PROFILE");
//reader.setTotalProperty("iwfs:OBJECTID");

final Store store = new Store(dataProxy, reader, true);
store.load();

ColumnModel columnModel = new ColumnModel(new ColumnConfig[]{
new ColumnConfig("Object ID", "iwfs:OBJECTID", 100, true),
new ColumnConfig("Ttile", "iwfs:TITLE", 75, true),

});

GridPanel grid = new GridPanel();
grid.setStore(store);
grid.setColumnModel(columnModel);
grid.setWidth(600);
grid.setAutoHeight(true);
grid.setTitle("Json Grid");
grid.setFrame(true);
grid.stripeRows(true);
grid.setIconCls("grid-icon");
panel.add(grid);

RootPanel.get().add(panel); Right now I get no errors but there is nothing in the grid I have checked height and width and that seems to be okay any assitance would be greatly appreciated
Thanks in advance

In your code you are setting the root to point to object. This is not supported. You need the root to point to object array..

refer this :
http://gwt-ext.com/docs/gwtext2/com/gwtext/client/data/JsonReader.html#setRoot(java.lang.String)




Jason:
"gml:featureMember":{
"iwfs:DDMS_PROFILE":{
JsonReader reader = new JsonReader(recordDef);
reader.setRoot("gml:featureMember.iwfs:DDMS_PROFILE");
