One-to-Many Relationships for Canvas apps - Not working

My app is no longer able to traverse related entities to retrieve field values.

If the data model is:

  • Account has many Contacts

The objective is to retrieve the account name for all Contacts. 


I would create a gallery with the items property equal to Contacts and create a text field within the gallery which has the following query for the text property:


The above query was working and was part of the release in One-to-Many Relationships for Canvas apps (  


This is currently working in the published app, but in while in build mode, the values are null.


I need to release a new version of the app, but cannot because of this issue.


Other things to note:

1.) I am working with custom entities created in Dynamics 365.

2.) I am able to query for ThisItem.Contact, but can no longer retrieve any values from the Contact table.


Please Advise,

Hi @srizvi ,

Do you mean that you can not search value in Contact entity when the app is in edit mode?

I've made a similar test but not met the same problem like your description.

My lookup field could display value in edit mode.

Firstly, you need to connect this app with Account entity and Contact entity.

Then, using the same step like your description.


So your formula should have no error. 

Here's my PowerApps version: 3.19111.28

I suggest you clear your browser's cache , update it to the latest version and try again.

If the problem still exists, I suggest you ask for help here:
