Re: Exception-undefined is not a function(While adding anchor to htmlpanel)

There might have been an error injecting the JSNI into the page.
I'd strongly suggest you try Super Dev Mode (this will be the default in GWT 2.7; I'd suggest you try 2.7.0-SNAPSHOT, JARs are available from https://oss.sonatype.org/content/repositories/google-snapshots/com/google/gwt/ , the very latest JARs built last night have superDevMode turned on by default when you launch the DevMode).

Hi,
I am getting exception while adding the Anchor to HTMLPanel,Below is the code


private HTMLPanel panel;
private HorizontalPanel hPanel=new HorizontalPanel();;

Anchor anchor=new Anchor();
anchor.setVisible(true);
anchor.getElement().setPropertyString("id", "hintButton");

public void createPanel(String title){
if(panel!=null){
hPanel.remove(panel);
}
panel=new HTMLPanel(title);
panel.add(anchor);   //exception while adding anchor to HTMLPanel second time
hPanel.add(panel);
}
the above code is working fine ,its creating the htmlpanel with anchor and executing fine for firstTime.When i am calling the Method createPanel for second Time its giving the below exception.
