Hi,
I have a page that contains a header div containing some anchors
defined in the html page. My GWT code finds the header with
RootPanel.get(String) and adds it to a DockLayoutPanel. I have tried
to attach click handlers to the links in the header like this:
header = RootPanel.get("header");
NodeList<com.google.gwt.dom.client.Element> aes =
header.getElement
().getElementsByTagName("a");
com.google.gwt.dom.client.Element item = aes.getItem(0);
Anchor anchor = Anchor.wrap(item);
anchor.addClickHandler(new ClickHandler()
{
public void onClick(ClickEvent event)
{
Window.alert("hi");
}
});
but get this exception
java.lang.AssertionError: A widget that has an existing parent widget
may not be added to the detach list
at com.google.gwt.user.client.ui.RootPanel.detachOnWindowClose
(RootPanel.java:136)
at com.google.gwt.user.client.ui.Anchor.wrap(Anchor.java:59)
Can anyone suggest how I should be approaching this situation?
Thanks,
John
