Cannot read property 'length'

[arcisd]

I obtain a problem using the "datepicker"component:

Cannot read property 'length' of undefined.

Any idea?

I also have got this error. It fire in function 'parse' because there is no checking for 'this.val'. When you use null in 'value' prop it return this error. There should be some test at the start of the function. For example something like this:
if( !str && !this.val) return new Date();
