Determine if tab is opened?

[Tbaseflug]

What is the best way to check if a tab is open/added? I need to check if Tab2 has been already added to TabPanel1 - if so, leave it else (re)load it...

I found this way... hope it help.

if (TabPanel1.findById("Tab2") != null){
    //Then the Tab2 is opened in TabPanel1
}
