Gallery for Repeating Section with a Managed Metadata field not working properly

[jeysicca]

Hi,

I have a 2 lists that are used in one powerapps form. One of the lists has a content type that I created with a managed metadata. I created an example below:

Groups List
Members List (with a content type and a managed metadata field)

I created a form that I connected the two. In a group, there can be 1 or more members. So this is my form:

we have the groups section where the details are saved to the Groups list and the members section where the details are saved in the Members list. The members section is a gallery where you can add multiple members. When clicking the Add Member button, it is supposed to add one duplicate section for the student information. However, when I clicked it, it adds more than 1 duplicate just like this:

The formula for Add Member button is

 

The LineDegree is the initialization of the Degree field because it is a Managed Metadata. While the Degree combo box has this formula to save it in the collection:

Thanks for your help.

Hi @jeysicca ,

Could you please share a bit more about your issue?

Do you mean that it would create more than one duplicate section rather than one duplicate section within your Gallery when you click the "Add Member" button?

Based on the issue that you mentioned, I have made a test on my side, and don't have the issue that you mentioned. The screenshot as below:

Set the OnSelect property of the "Add Member" button to following:

Collect(
        MembersCollection,
        {
            LineTitle: "",
            LineYear: {
                Value: ""
            },
            LineDegree: {
                '@odata.type':"",
                TermGuid: "",
                WssId:"",
                Label: "",
                Path:"",
                Value: ""
            }
        }
)

Please check the following GIF screenshot for more details:

Please check if you used another formula to add record into your MembersCollection. Also please check if you have typed your Collect() formula in other place of your app except the "Add Member" button.

In addition, please also consider take a try to add a Index column within your MembersCollection to act as Row Index. Please consider modify the Collect formula within the "Add Member" button as below:

Collect(
        MembersCollection,
        {
            Index: CountRows(MembersColelction) + 1,
            LineTitle: "",
            LineYear: {
                Value: ""
            },
            LineDegree: {
                '@odata.type':"",
                TermGuid: "",
                WssId:"",
                Label: "",
                Path:"",
                Value: ""
            }
        }
)

Set the OnVisible property of the current screen to following:

Clear(MembersCollection);
Collect(
        MembersCollection, 
        {
           Index: CountRows(MembersColelction) + 1, 
           LineTitle: "", 
           LineYear: { Value: "" }, 
           LineDegree: { '@odata.type':"", TermGuid: "", WssId:"", Label: "", Path:"", Value: "" } 
       } 
)

Then please use UpdateIf() function to update records in your MembersCollection instead of Patch function. Modify your formula as below:

UpdateIf(
        MembersCollection,
        Index = ThisItem.Index,
        {
            LineDegree: {
                '@odata.type':"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedTaxonomy",
                TermGuid: DegreeComboBox.Selected.TermGuid,
                WssId: DegreeComboBox.Selected.WssId,
                Label: DegreeComboBox.Selected.Label,
                Path: DegreeComboBox.Selected.Path,
                Value: DegreeComboBox.Selected.Value
            }
        }
)

Please take a try with above solution, then check if the issue is solved.

If the issue still exists, please consider re-create a new app, then take a try with above solution I provided, then check if the issue is solved.

Best regards,
