Hi,

 

I have a datawindow which selects data from two different tabels(using a join) with a one to one relationship.

When i create a datastore with this datawindow, and I use the RetrieveAsync/RetrieveByPageAsync methode, I get the values of both tables in my datawindow.

In this case the "City" and "CntryCode" are properties from the second table.

But when i use the RetrieveByKeyAsync methode, only the data of the first table is given. The proprties of the second table are null.

Is there something extra i should add ?

Swagger.xml is being used by another process

Hi Aaron,

I couldn't find anything in the documentation that might describe this behavior so it's possible that it is a bug.
Please create a simple test case that reproduces this issue and submit it through our support portal

Regards,
Francisco

Hi Aaron,

Please notice that the RetrieveByKey method uses the [Key] attributes applied to the model to generate a new SQL Select to query data from the table.

You need to use the Retrieve method to execute your original SQL Select to query data from multiple tables.

Regards, Logan
