View Full Version : [FNR] TabPanel.update(Widget, TabItemConfig) removes styling

14 Nov 2011, 4:09 AM
In order to change the caption for tabs after they have been added, I tried to use TabPanel.update as described here: http://dev.sencha.com/deploy/gxt-3.0.0-dp5/javadoc/gxt/com/sencha/gxt/widget/core/client/TabItemConfig.html

The update itself is working, but the Styling/HTML of the tab header gets fully lost. You can test this issue, with the following code:

public class MyModule implements EntryPoint {
public void onModuleLoad() {

BorderLayoutContainer container = new BorderLayoutContainer();

final TabPanel tabs = new TabPanel();

final ContentPanel cp1 = new ContentPanel();
cp1.setHeadingHtml("Tab 1 Headline");
final TabItemConfig tabItem1Config = new TabItemConfig("Tab 1");
tabs.add(cp1, tabItem1Config);

ContentPanel cp2 = new ContentPanel();
cp2.setHeadingHtml("Tab 2 Headline");
TabItemConfig tabItem2Config = new TabItemConfig("Tab 2");
tabs.add(cp2, tabItem2Config);

Button b = new Button("Update the caption for Tab 1");
b.addClickHandler(new ClickHandler () {
public void onClick(ClickEvent event) {
tabItem1Config.setHTML("New Tab 1");
tabs.update(cp1, tabItem1Config);

BorderLayoutData layoutData = new BorderLayoutData(100);
container.setCenterWidget(tabs, layoutData);
container.setNorthWidget(b, layoutData);

Any reaction? Did anybody from the GXT dev team try to reproduce this error with the test case I provided?

I am facing the same issue with 3.0.6. What should I do now ?
