angularjs ng-show with promise expression

Question

I\'m using ng-show with an expression that resolves to a promise that resolves to a boolean. When I do this I get the 10 digest iterations overflow.

Answer 1

If you check out the sources here you 'll see that the promise is resolved in nextTick, so the $scope only changes the next time angular makes a $digest cycle. But your function returns a new promise on every $digest cycle, never actually getting the resolved value of the previous promise.

It's an old problem discussed here also.

You can overcome this issue by keeping a "persistent" reference to your promise outside the function as I did here.
