Get One-time Binding To Work For Ng-if

This question has been asked before, but I can't get that solution working, so I'm wondering if there's something different in my specifics. The code is really, really simple: <

Solution 1:

Well, In here you're checking one-time data binding vm.building.name value with undefined and since it is one-time data binding this condition will always be false.

modify your ng-if and make it more simpler

<h1 ng-if="::vm.building.name">update {{::vm.building.name}}</h1>

This will work!

Cheers!
