compiler exception during deployment since 2.1.3, bapi + relation

Hi,

I just updated SUP to 2.1.3 and can't deploy my project anymore (worked with 2.1.0). I have two MBOs BusinessPartner and Opportunities. Both MBOs are in relation. The primary key of BusinessPartner, BP_NUMBER, is mapped as an One-To-Many relation to the load parameters of Opportunities (see picture).

This relation will cause an deployment error with the following exception (see MBO Relation Log.txt):

If I delete the relation, it will deploy. This relation did work in 2.1.0 though.

Any thoughts?

Thanks,

Christian
