The inputDate only works if no date was selected before

[CheckHelzio]

Hi!
First of all thanks for the wonderful work creating this component.

The inputDate works to open the datePicker on a specific date, but after I use the datePicker to select any other date, the inputDate does not work again.

What can I do if I want to open the datePicker always on the same date, even if I already select another one?

@CheckHelzio May I know what your use case is for this kind of purpose? I'd like to know a little bit more on what approach to best suit your use case. And I understand you want it to be able to reset to the given inputDate everytime the datepicker opens. Am I correct?

[CheckHelzio]

I am developing an application that is a calendar of the events that will be in my university.

I use the datePicker to navigate faster to a specific date. Also as a shortcut to return to today.

I use it also to generate reports of the events, selecting the initial and final date of the report.

@motss Yes, whenever the datepicker opens, I would like to reset the inputDate.
And also I have something like this.

<app-datepicker id="picker" date="{{testDate}}"></app-datepicker>

this.$.picker.inputDate = x;
# Then testDate was set as x?

testDate was set as date which I gave in inputDate? Is this the right flow?

@sp1rs reset inputDate or resete date?

[sp1rs]

@motss both inputDate and selectedDate.

@motss and why setting inputDate, changes data also ?

[motss]

@sp1rs inputDate will directly affect the selected date internally but that does not actually update the date which will output the selected date. Why? It's because app-datepicker usually use within a dialog and only clicking the OK button will trigger updating the value date whereas CANCEL button means you don't want to output the selected date. But for app-datepicker has another method called enforceDateChange which will update the app-datepicker (not app-datepicker-dialog).

@sp1rs The use case to me is quite rare. The only way to do is to introduce a flag for this kind of use case.

[motss]

@sp1rs @CheckHelzio cd8d97c should fix this with newly added flag alwaysResetSelectedDateOnDialogClose.

[motss]

The demo always updated with this rare use case. PTAL. 👍

Updated demo with alwaysReset flag

Thanks, @motss

@motss When is the fix going live?

[motss]

@sp1rs Since the Polymer 2.0 went stable, I'm still working on maybe this can be a hybrid element for the latest stable version alongside this patch. Of course, as always, help are definitely welcomed. Stay tuned~

[motss]

@sp1rs Please check out the latest release which has been upgraded into a hybrid Polymer Element! 🌮 🎉

@motss awesome, thanks a lot.
