Hallo Leute,

ich hab da ein kleines Newbie-Problem.

Sobald ich ein Discriminator-Element in das Mapping-File für meine abstrakte Superklasse "Vehicle" einfüge, schmiert die Anwendung ab. Nehme ich das Discriminator-Element wieder raus, läuft alles.

Ich kann keinen Tippfehler erkennen. Was mache ich falsch?

wenn ich mich auf die Schnelle nicht irre, muss der "disriminator" VOR dem Versionselement stehen.

Ich Seggel hatte ganz vergessen, dass es bei den DTD-Angaben (hier im StackTrace) ja auch auf die Reihenfolge ankommt.

Vielen Dank, curio. Das war's. :)

*kicher* bin ja nur froh, dass ich nicht der Einzige bin, dem das passiert ;)
