Hi antonhh,
I'm new to Power Pages, and I'm having the same issue. in my case I'm using Dynamics365fo Virtual Entity. Viewing/Editing data works fine for newly created DV tables, but I'm not able to get related row info. for a given record in a list from D365fo entity.
I've also tried to use Id parameter as well as primary key field, but no results are shown. I guess we're missing something here but I haven't been able to found it yet...
Here is the automatic guid unique identifier from the entity:
Here is the unique identifier from the table
This is the list setup:
List setup showing parameter 'Id'
Edit form setup (the same setup applies to View form but ReadOnly mode):
Edit form parameter 'Id'
When I'm opening a form (Edit/View) using a new page, it seems that the 'Id' parameter is being sent correctly, since I can see the parameter Id in the page url, but no data is shown in the forms:
Edit forms url showing the 'Id' parameter
https:\\portalexample.xxx.com/Audit-View-details/?id=0000554b-0000-0000-0000-005001000000
In addition, If I look for the the given 'Id' in the entity data I'm able to find the associated record.
Let's see if someone can help us...
