md-select converts numbers to strings

[daniel-nagy]

The md-select directive will convert a Number to a String. This may result in unexpected $watch events triggering. For example,

$scope.number = 10;

$scope.$watch('number', function (newValue, oldeValue) {
    // newValue = "10", oldValue = 10    
    if(newValue === oldeValue) {
        return;
    }
    ...
}

I suggest adding a type attribute to the md-select directive.

A proper support for 'ng-options' would probably solve this issue . There is an open ticket: #1837.

Btw. Another side effect of this unintended conversion is that it triggers the form dirty flag.

Yes even I've faced this issue. Took some time to figure it out 😄

I've faved the same issue. I get douplicated $watch triggers when ever the Selektion changes.

@daniel-nagy looking at your example - can you just use ng-value instead of value? Please notice that ng-change is not triggered at first load as expected (no change happened yet).

@ThomasBurleson initially created fix for this particular issue targeted for numbers with c9f2b9f but it was reverted with recommendation to use "ng-value" with b983c0d by @rschmukler

I believe unless "ng-value" is not an option for you guys, this issue can be closed?

@skosno I've been using ng-value without any issues. I believe this issue can be closed.
