DateTime not working for dayValues attribute

When using the dayValues attribute in <ion-datetime> something like this:

 <ion-item>
       <ion-label>Date</ion-label>
       <ion-datetime monthValues="6,7,8" yearValues="2014,2015" dayValues="01,02,03,04,05,06" displayFormat="DD/MMM/YYYY" [(ngModel)]="myDate"></ion-datetime>
</ion-item>

i get the error as:

Cannot set property ‘disabled’ of undefined
at DateTime.validate (datetime.js:486)
at DateTime.open (datetime.js:350)

What could be the issue for this?

I am running into this as well. Does anyone perhaps have a fix or work-around for this issue already?

Cheers
