Thread: How to run a "Add"-method from a method?

Hi all,


I've a Java code (GWT):

package com.practicum.client.out;
 
import java.util.ArrayList;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.google.gwt.user.client.ui.Widget; 
import com.google.gwt.visualization.client.DataTable;
import com.google.gwt.visualization.client.AbstractDataTable.ColumnType;
import com.google.gwt.visualization.client.visualizations.corechart.AxisOptions;
import com.google.gwt.visualization.client.visualizations.corechart.ColumnChart;
import com.google.gwt.visualization.client.visualizations.corechart.CoreChart;
import com.google.gwt.visualization.client.visualizations.corechart.Options;
import com.practicum.client.Product;
import com.practicum.client.rpc.ProductService;
import com.practicum.client.rpc.ProductServiceAsync;
 
 
public class DataOutColumnChart {
	private DataTable data = DataTable.create();
	private Options options = CoreChart.createOptions();
	private final ProductServiceAsync productService = GWT.create(ProductService.class);
 
	public DataOutColumnChart(Runnable runnable) {
	}
 
	public Widget createColumnChartView() {
		/* create a datatable */
		data.addColumn(ColumnType.STRING, "Price");
		data.addColumn(ColumnType.NUMBER, "EUR");
		addData("A for Apple", 123); // THIS WORKS
		addData("B for Boy", 123); // THIS WORKS
 
		/* create column chart */
		options.setWidth(400);
		options.setHeight(300);
		options.setBackgroundColor("#e8e8e9");
		AxisOptions vAxisOptions = AxisOptions.create();
	    vAxisOptions.setMinValue(0);
	    options.setVAxisOptions(vAxisOptions);
 
		return new ColumnChart(data, options);
	}
 
 
	public void getWinkels() {
		productService.getWinkels(new AsyncCallback<ArrayList<Product>>() {
			public void onFailure(Throwable caught) {
			}
 
			public void onSuccess(ArrayList<Product> result) {
				for (Product p : result) {
					addData("C for Candy", 123); // THIS DONT WORK?
					System.out.println(p.getWinkel()); // THIS WORKS
				}
			}
		});
	}
 
 
	public void addData(String winkel, int prijs) {
		int rownr = data.addRow();
		data.setValue(rownr, 0, winkel);
		data.setValue(rownr, 1, prijs);
	}
 
}

Can someone explain me why line 30 and 31 works,
but line 51 not works? Simply nothing happens on line 52...

I've tried anything...

Thanks in advance!
