Java: InfoTable addRow of ValueCollection puts empty

Hi Jakub,

Sorry, this is old thread, but i am seeing same scenario for Mashup.

It worked for executing service in Composer, i can see the rows with data, but when it goes to Mashup, when i am assigning this infotable to gird, grid showing empty rows (no data) ?

is there anything that changed ? i am trying this snippet with Thingworx-SDK 8.3

below is my code.

@ThingworxServiceDefinition(name="getSampleInfotable", category="", isAllowOverride=true, description="")
@ThingworxServiceResult(name="result", baseType="INFOTABLE", description="Sample Infotable Service")
public InfoTable getSampleInfotable() throws Exception{
DataShapeDefinition dsd = new DataShapeDefinition();

dsd.addFieldDefinition(new FieldDefinition("field1", "NUMBER"));
dsd.addFieldDefinition(new FieldDefinition("field2", "NUMBER"));
dsd.addFieldDefinition(new FieldDefinition("field3", "NUMBER"));

InfoTable it = new InfoTable(dsd);
ValueCollection row = new ValueCollection();

Random rnd = new Random();
for(int i = 0; i < 10; i++) {
row.SetNumberValue("field1", new NumberPrimitive(rnd.nextInt(100)));
row.SetNumberValue("field2", new NumberPrimitive(rnd.nextInt(100)));
row.SetNumberValue("field3", new NumberPrimitive(rnd.nextInt(100)));
it.addRow(row.clone());
}

return it;
/*
ValueCollection params = new ValueCollection();
params.SetInfoTableValue("ServiceITParameterName", prop); // my service had just one parameter of type InfoTable

client.invokeService(ThingworxEntityTypes.Things, "ThingName", "ServiceName", params, 1500);
*/
}
