Context variable not updating OnChange

Posted on by Community Power Pla... Microsoft Employee

I'm running into an issue where the Date/Time that I'm generating `ITime` is correctly displayed in Label1.Text when the screen shows up (OnVisible), but when changing dropdowns, from say 8:00pm to 4:00pm, ITime doesn't update until the 2nd time it's changed, back to 3:00pm, ITime = 4:00pm (previous change).

Screen1.OnVisible = UpdateContext({
 IDate: DatePicker1.SelectedDate,
 IHour: HourPicker1.Selected.Value,
 IMinute: MinutePicker1.Selected.Value,
 IAMPM: AMPMPicker1.Selected.Value,
 ITime: IDate & " " & IHour & ":" & IMinute & " " & IAMPM
})

Label1.Text = ITime

ITime = 4/25/2018 8:00 PM

HourPicker1.OnChange = UpdateContext({
 IHour:HourPicker1.Selected.Value,
 ITime: IDate & " " & IHour & ":" & IMinute & " " & IncidentDateAMPM.Selected.Value
})

Label1.Text doesn't change until DatePicker1 is changed a 2nd time.

ITime = 4/25/2018 8:00 PM (OnVisible)
ITime = 4/25/2018 8:00 PM (HourPicker1 changed to 4:00 PM)
ITime = 4/25/2018 4:00 PM (HourPicker1 changed to 3:00 PM)

ITime = 4/25/2018 3:00 PM (HourPicker1 changed to 9:00 PM)

It's acting like it's a step behind updating ITime?

I think that is the way how it works.

OnChange property would trigger the event when users trying to change the Dropdown Value, and please note it, the formula runs before the value changes was done, not after it.

So when the commands executing, the

HourPicker1.Selected.Value

Keeps the previous value.

If you would like to keep the current value, then please just use the

DatePicker1.SelectedDate&" "&HourPicker1.Selected.Value&": "& MinutePicker1.Selected.Value & " "&AMPMPicker1.Selected.Value

Michael

Thank you Michael!

The issue was actually that ITime can't be generated in the same UpdateContext() formula. I just did a new UpdateContext() on the next line and it worked as expected.
