Thread: Initial value for HtmlEditor contains an unwanted character

  1. #1

    Default Initial value for HtmlEditor contains an unwanted character

    Initial value for HtmlEditor contains an unwanted character named 'ZERO WIDTH SPACE'.
    Sample code tested on FireFox and Chrome
    import com.extjs.gxt.ui.client.event.ComponentEvent;
    import com.extjs.gxt.ui.client.event.SelectionListener;
    import com.extjs.gxt.ui.client.widget.Info;
    import com.extjs.gxt.ui.client.widget.TabItem;
    import com.extjs.gxt.ui.client.widget.TabPanel;
    import com.extjs.gxt.ui.client.widget.Viewport;
    import com.extjs.gxt.ui.client.widget.button.Button;
    import com.extjs.gxt.ui.client.widget.form.HtmlEditor;
    import com.extjs.gxt.ui.client.widget.layout.FitLayout;
    public class TestHtmlEditor implements EntryPoint {
    	public void onModuleLoad() {
    		Viewport viewport = new Viewport();
    		viewport.setLayout(new FitLayout());
    	private TabPanel createGUI() {
    		TabPanel tabPanel = new TabPanel();
    		return tabPanel;
    	private TabItem createPage() {
    		TabItem page = new TabItem();
    		page.setText("Page with HTML Editor");
    		final HtmlEditor editor = new HtmlEditor();
    		Button btn = new Button("Get value");
    		btn.addSelectionListener(new SelectionListener() {
    			public void componentSelected(ComponentEvent ce) {
    				String text = editor.getValue();
    				char c = text.charAt(text.length()-1);
    				int i = (int)c;
    				if(i == 8203) {
    					Info.display("Bug ?", "Last char in text contains ZERO WIDTH SPACE");
    		return page;

    This is not a bug. This was needed so that htmleditor shows the cursor when you initially click into it.

    In the meantime this got fixed within GWT directly

    This was only fixed in GWT 2.0.X we cannot remove it yet.

    If you use GWT 2.0.X you can add


    to your code.
