Hard time getting Browser tab selectors

I have a web application which opens a page in another tab. I am having a hard time attaching to the newly launched tab. Tried clicking on the tab, on the address bar, on the window title, within the new tab. But I keep getting errors at run time that the selectors are invalid
The tab title is Dashboard

All the selectors are starting with <wnd …> instead of < html…>

i only get <html…> selector when clicking on the IE window title but even that seems invalid.

Any better way to just attach to a browser tab ?

Ajit

Can you show us how selector looks like?
Have you tried use URL and activate browser?

You used attach window for the new opened window??

yes, used attach window and the selectors are going bonkers.

make sure when inside open browser or attach window, to use partial selectors…
