Thanks for message.
It seems that there is an inconsistency in Doctrine2 specification because in XML this is a valid specification:
<embedded name="address" class="Address" use-column-prefix="false" />
but in annotation this is a correct form:
/** @Embedded(class = "Address", columnPrefix = false) */
We have to find a way how to allow to define single property for two different names. In the meanwhile feel free to manually update Doctrine2.cfg.xml file located in installation directory and update "use-column-prefix" definition to "column-prefix".
