Power App combobox people picker returns blank

In one of the app we have used few Combo Box, all of the Combo Box returns some value when writing "ComboBox.Selected.Value" except in some cases where Combo Box is used as the people picker where when writing "ComboBox.Selected.DisplayName" returns blank always.

What I am trying to do in the app is:
All the people in the org have some tasks to do, the app is used to add/edit/delete the task for a particular person. Whenever there is person assigned to a task by selecting the name of the person from the people picker, then he/she should be allowed to select the Workdays from another Combo Box's and enter time into text label.

 

If no user assigned to a task, this means the people picker combo box will be blank. If the combo box is blank, then show the Text label "NA" in case of Workdays and Time.

 

Because the people picker combo box always shows blank when writing "ComboBox.Selected.DisplayName". The condition for making other controls visible/hide is not consistent.

Hi @kp19 .

What is the Items and DefaultSelectedItems (in Text please) of the Combo Box and the Update of the Data Card. Also is it (and the field) single or multiple value ?

Hi @WarrenBelz,

Thanks a lot for taking time to helping me.
Please find the required details below.

Items: Filter(Office365Users.SearchUserV2({searchTerm:Trim(Self.SearchText),isSearchTermRequired:false}).value,AccountEnabled=true)


DefaultSelectedItems: {Value:Parent.Default}


Update: ComboBox.Selected.DisplayName

Select Multiple is set to false for combobox.

Hi @kp19 ,

When you use the Office365Users structure to get the selection, the schema is different, so with Items of

Filter(
   Office365Users.SearchUserV2(
      {
         searchTerm: Trim(Self.SearchText),
         isSearchTermRequired: false
      }
   ).value,
   AccountEnabled
)

you need DefaultSelectedItems of (using your field name)

{
   Claims: "i:0#.f|membership|" & Lower(ThisItem.PersonField.Email),
   Department: "",
   DisplayName: ThisItem.PersonField.DisplayName,
   Mail: ThisItem.PersonField.Email,
   JobTitle: "",
   Picture: ""
}

and Data Card Update of (using Combo Box name)

{
   Claims: "i:0#.f|membership|" & Lower(ComboBox.Selected.Mail),
   Department: "",
   DisplayName: ComboBox.Selected.DisplayName,
   Email: ComboBox.Selected.Mail,
   JobTitle: "",
   Picture: ""
}

Also ensure that the Display field (select combo box then Edit from the right panel) is DisplayName.

Hi @WarrenBelz ,

I did all the steps you mentioned. 
In the Update property of Data Card, I have used the code that you provided. I am getting error that says "expected Text value" in the formula bar.

@kp19 ,

Check that the Combo box is single selection. The code is correct for that.

Hi @WarrenBelz ,

The SelectMultiple property of ComboBox is set to false.

The column data type is "Single line of text".

 

DefaultSelectedItems property of ComboBox is:

{
   Claims: "i:0#.f|membership|" & Lower(ThisItem.Preparer),
   Department: "",
   DisplayName: ThisItem.Preparer,
   Mail: ThisItem.Preparer,
   JobTitle: "",
   Picture: ""
}

I am not getting option to select Mail or DisplayName after writing ThisItem.Preparer.

 

Please do let me know if I have to change the data type of the column in SharePoint to Person type.

@kp19 ,

Why are you using  People Picker to write back to a Single Line of Text column - I (naturally) assumed that it was a Person field. So we are back to basics here - which field (Name or Email) do you want to save to the text field (you cannot save them both)
