Open a new instance of GWT app

Question

I'm developing a GWT web App . Righ now I have one default EntryPoint: AppWeb.

The page works perfectly if I run it in the web browser:

http://localhost/AppWeb.

If I open a new tab, and write the same URL, the App works just fine as two instances.

Now, I just want that a simple button in my app open a new windows of the same app and same entry point, just like a new instance. But is not working. I'm using this:

Window.open("AppWeb?guiId=xxx", "_blank", "");

The problem is that the new tab is openen, but is not calling the onModuleLoad of the AppWeb entry point.

What happens in that new Window? Does it load the host page? — Andrei Volgin
I have a static object Application that draws all the stuff. It's like isn't creating a new one.. and instead use the same instance. — Mariano L

I think you could do it using an anchor http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/Anchor.html

Set the anchor target with

myAnchor.setTarget("_blank");

in your code and in the ui

<g:Anchor ui:field='my anchor' href='' text='click here to duplicate'/>

Note the empty href='' (because it would be appended to your current url).

I tried it and it calls onModuleLoad() when the entry point is called on the new tab.
