(solved) Grouping doesn't work anymore when grouping attribute is undefined

Version 9.0 build 3254
A video and BSV is to be found here:

Steps to reproduce:

1. Click the INIT/RESET button. This creates one "garage" object called North. Three "car" objects that are related to this garage. Three "type" objects that are related to the car BO but no specific car. This is used for grouping inside the garage form.
2. Look at the queries at the visual perspective. The garage and the cars have been successfully created.
3. Click "EDIT" on the garage object called North to enter the form.
4. The cars are supposed to be visible inside the grid grouped by "type", but only one car is visible as long as they don't have a type.
5. Edit a "car" object and pick any type from the dropdown. There will now be 2 cars visible in the "garage" form.

Conclusion: When the "type" shortcut is used for grouping, and the type is undefined/null, only one object will be displayed in the grid. This is not the same behaviour as previous versions of AwareIM.

This was fixed in V9 Build 3257 and I can confirm that it works now.
