Data grid by Xpath : Response JSON is empty

1

Not knowing why an application throws the message "Data grid by Xpath : Response JSON is empty" as a pop-up when retrieving an entity. Previosly this workend fine and I have no idea what causes this behaviour. In this part of the application I dont use REST or JSON so I think its something in the UI. Any suggestions on cause and fix?

I would suggest using 'from Database' as source if you're not setting any XPath constraints. That will probably help you fill up the grid again.

Apart from that: The requests being done from the client to the server (and the responses) are in JSON, hence the response message.

This problem has been opened as Issue with support. An other user experiences same problem, Possibly this has to do with handling of virtual attributes in 7.6.0. In my case it occurs with multiple entities..
