Hi Markus,
To me it looks like you're getting bitten by the "applyRestrictingQualifierOnInsert" feature:
## Specifies that you want restricting qualifiers "applied" to your newly
## inserted objects. For instance, if you have an entity that is part of
## single table inheritance and your restricting qualifier only uses
## EOAndQualifiers and EOKeyValueQualifiers, ERX can interpret the qualifier
## and make your EO's automatically match the restricting qualifier. This
## allows you to skip the awakeFromInsertion step where you have to remember
## to make your EO match the restricting qualifier you chose in your model.
# er.extensions.ERXEnterpriseObject.applyRestrictingQualifierOnInsert=true
The makeQualifierTrue method in ERXEOControlUtilities is not able to handle your case (and apparently shouldn't). Overriding applyRestrictingQualifierOnInsert() in ElectronicDocument and returning false should do the trick…

Using ERXGenericRecord ultimately results in the following crash (dump below). Action was creating a new ElectronicDocument in a D2W app.
