I have to add a null value to a EList of Double. Unfortunately, this does not seem to be possible.
Is there a way to achieve this without adding/inventing a dummy Type that marks the value as null?

Erdal,

please post some example code and the error message/exception, if there
is one. We can only tell if there is a solution or if this is a bug, if
we get enough information.

Cheers,
Stefan

Stefan,

Yes, it's often hard to know details unless they're provided.

The issue might be as simple as using EDoubleObject rather than EDouble
as the EDataType of the EAttribute; the former allows null but the
latter does not...
