Originally created by @roelfsche on GitHub (Oct 28, 2020).

I use a legacy data model, which has a compound primary key, made of a string and a datetime column.
If I try to fetch data as objects, I get an exception

In UnitOfWork.php line 2625:
[ErrorException]
Catchable Fatal Error: Object of class DateTime could not be converted to string

The reason is:
$idHash = implode(' ', $id);

and $id = [ 'date' => DateTime, 'myOtherString' => ....]

May be, the "flattenIdentifier" method should recognize DateTime-Fields and cast them to strings?
Thank you.
