md-select deselects when the value is 0 (instead of selecting the item with value of zero)

[geelus]

Bug, feature request, or proposal:

Bug

What is the expected behavior?

Selecting the value 0

What is the current behavior?

Deselects everything

What are the steps to reproduce?

One your changes for version beta 6 is:
"select: allow option with undefined or null value to clear selection (#3141) (13524c1), closes #3110 #2634"
This causes the issue of deselecting if the value is 0. So it deselects the mdselect if it's null or undefined or zero.
Providing a Plunker (or similar) is the best way to get the team to see your issue.
Plunker template: https://goo.gl/DlHd6U

What is the use-case or motivation for changing an existing behavior?

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

beta 6

Is there anything else we should know?

This has been fixed in master and will be in the next release. See 2e3910c.

Perfect. Thanks

I checked the link and I guess it's a different issue. My problem is that when my ngModel is zero, instead of selecting the option zero, it deselects it all.

[crisbeto]

It should be the same issue. Can you reproduce it in a Plunkr? You can use this one which runs the latest build.

[geelus]

If you believe so, I trust you. I will when I get a chance.

We had a similar PR today and I wasn't able to reproduce it in this Plunkr. I'm not sure whether you have a different setup though.

Here is the plunker:

but I'm getting a strange error:
"Can't bind to 'ngModel' since it isn't a known property of 'md-select'"
how come???!!!

[crisbeto]

It's because the template doesn't include the FormsModule. Here's a fixed version and it also looks like selecting 0 works.

[geelus]

Thank you for fixing the issue. Is the plunker you sent the one in dev (fixed) or beta 6 (released)?

[crisbeto]

The Plunkr is using the latest master build.

[geelus]

Perfect! so it's fixed.

[jonsamwell]

Any idea when the next release is that will deliver this fix?

[geelus]

Good question. I would love to know too.
