grid.addData question

Smart GWT Technical Q&A

Hi,

I have a grid based on a DataSource that calls Rest WS. When I add a record in the grid the insert into database is done. The rest WS return this XML

<id>32422</id>

This is the id (oracle sequence) generated by the server.

I override the transformeResponse in DS

protected void transformResponse(DSResponse response, DSRequest request, Object data) {

	switch (request.getOperationType()) {
	case ADD:
		String id = XMLTools.selectString(data, "/id");
		response.setAttribute("id", id);
		break;
	}
	super.transformResponse(response, request, data);   
}

I add records in the grid with a callback in this way

rec.setAttribute(“name”,“English”);
rolsUsuariGrid.addData(rec, new DSCallback(){
public void execute(DSResponse response, Object rawData, DSRequest
request) {
String id = response.getAttribute(“id”); //id returned by the server
???
}
});

I don’t know how I can assign the id returned by the server to the record just added.

Thanks!
