PowerApps - Existing Date picker component - Current month date is not selectable

 Issue faced in the existing app - "Date Picker v3.msapp" downloaded from other source:

  • I've a screen where the date picker is displayed and lets assume that the current month is May. After opening the screen, I'm trying to pick a date, lets say May 3rd. When I click on 3rd, the date is not selected. 
  • But, 
    • I navigate to Previous month (by clicking < icon) and selected some date in that previous month and come back to current month then selected the date, now the 3rd May is selected. Or
    • I navigate to Next month (by clicking > icon) and selected some date in that next month and come back to current month then selected the date, now the 3rd May is selected. 
Date picker - UI

Code before fix: 
  • Code written in OnSelect property - when the Date is selected from the date picker, this code will be executed. 
  • The issue: "_firstDayInView" variable is not set initially.
Title_MonthDay_1 control - OnSelect

Code after fix:
            If block is added before the existing code where set the "_firstDayInView" if it is blank. 

Title_MonthDay_1 control - OnSelect

            If you notice the Next / Previous icon - OnSelect property in the existing code, the same code "set the "_firstDayInView" if it is blank" is written.

Note : Other controls data should be cleared only when 1st control's value is changed manually by the user.     Code written in OnChange property of 1st control:      Code written in Default property of other 2 controls:     Code written in OnVisible property of "My screen":     Scenario:  From gallery screen, I've opened the record (let say R2), the OnChange event in 1st control is not triggered, so other controls data is not cleared as expected.  When trying to open the different record (lets say R4) for the second time, the OnChange event in 1st control is triggered and so other controls data is cleared. But in this scenario, the OnChange event code must not be executed...
