Patch Collection makes Edit Form unavailable

[AdrianMitroiu]

Hi there,

I have created an app based on a SP List as a questionnaire.

Based on the user answers I marked the questionnaire as 'Completed' or 'Incompleted' using the "Patch" function to update a column in collection that is not in the SP List. 

Collect(
        QuestionnairesList,
        {
            Status: "",
            ...
         }
 );
If(_condition_, 
       Patch(
            QuestionnairesList,
            First(
                Filter(
                    QuestionnairesList,
                    Title = AddTitleInput.Text
                )
            ),
            {Status: "Incomplet"}
        ),
        Patch(
            QuestionnairesList,
            First(
                Filter(
                    QuestionnairesList,
                    Title = AddTitleInput.Text
                )
            ),
            {Status: "Complet"}
        )
)

My problem is that when I Edit the questionnaire the "Item" property of the form shows the Error: "Invalid formula. Expected a value compatible with 'DataSource'."

I should mention that:

• the Gallery Items is 'QuestionnairesList' collection
• the EditForm Item is 'Questionnaires.Selected' ( Questionnares is the name of the Gallery)
• the EditForm DataSource is 'QuestionnairesList'

Before I add the "Status" column in the collection, Edit form worked as it should.

What am I missing?

Hi @AdrianMitroiu,

The error message is caused by that when the field property in the Edit Form doesn’t match to the structure of the DataSource.

I assume that there’s a ID column in your collection

You can try to set Items property of EditForm to :

LookUp(QuestionnairesList,BrowseGallery1.Selected.ID=ID)

Thank you for your reply @v-sheyu-msft,

Your solution, as far as I have tried, works. 

Meanwhile I have created a second collection where I have stored the ID from the QuestionnairesList and the Status that it gets after my condition.

However i have to agree that your solution is clearer.

Thank you for your time.

Adrian.
