I tested everything with a seperate .hbm.xml file ad it worked fine. Now I need to integrate my files in the build-system of the rest of the project, which works with xdoclet, and this Problem occured. I also found no merge-point in the templates which let me specify my id-tag in a plain merge-file. --------------------------------------------------------------------- JIRA INFORMATION: This message is automatically generated by JIRA.
