IllegalArgumentException: To cannot be null in DocFileManager.getRef -------------------------------------------------------------------- Key: HBX-1094 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1094 Project: Hibernate Tools Issue Type: Bug Components: hbm2doc Affects Versions: 3.2.4 Beta1 Environment: Windows, Java 1.6.0_10, Oracle 10.2, Hibernate 3.2.6 Reporter: Gérald Quintana Running Hbm2Doc on a bunch of JPA annotated Entities, I get and IllegalArgumentException: To cannot be null in DocFileManager.getRef (see stack trace below). Some HTML files (\hbm2doc\tables\default\MY_TABLE.html) gets created before Hbm2Doc ends with this exception. There might be something in one entity code making the table.ftl FreeMarker template fail. Improving error log could help (which table has a problem?).
