[Date Picker] Year selection is broken

[mgibeau]

Trying to select a year from the date picker throws an error, using version 0.13.
Uncaught TypeError: Cannot read property 'isSelectedDateDisabled' of undefined

Can be reproduced on:
http://material-ui.com/#/components/date-picker

On the other hand, it seems to work fine if you click the month after selecting the year.

This is a regression introduced by my latest PR to improve perf on the date picker.
This is the line responsible from the error https://github.com/callemall/material-ui/blob/master/src/date-picker/date-picker-dialog.jsx#L146. I don't understand what isSelectedDateDisabled is for. Same for _selectedDateDisabled that was introduced by f8bdaf3. @jkruder Any idea?

Broken for a month now?

[oliviertassinari]

Well, yes, it's still broken, we need better unit test for the datepicker.

+7 for this and fixing this and with a large # of values. Some of us are trying to get apps into production using this stuff

[oliviertassinari]

I agree, this should be a priority.

[oliviertassinari]

This should be fixed on the master branch, sorry for this long response time!

@oliviertassinari Any idea how long it will take to get this into 0.14.0? using 0.14.0-rc1 in order to get around some other broken things in x.13.x.

[oliviertassinari]

We should have kept a 0.13.x to release hot fixes, but we didn't.
I hope that we can release 0.14 before the end of the year. We are doing heavy changes with this up coming release.
