How to open page in new tab/window?

Question

I need to perform something like app.showPage(app.pages.%PAGENAME%)but open the page in new tab.

Is it even possible in appmaker?

I am not opening an external link, I need to open the page of the app in a new tab.

Answer 1

Client property app.buildUrl().__gwt_instance.a; contains app's URL.

Not sure if a good practice, however it fulfilled my needs
