[jboss-user] [JBoss Seam] - seam-gen 'generate-entities' generates invalid code for tabl

Using seam-gen 'generate-entities' to generate a CRUD application from an existing PostgreSQL database does not generate working code. I have the follwing two tables in my database: Table t_user | CREATE TABLE t_user | ( | email character varying(255) NOT NULL, | firstname character varying(255), | lastname character varying(255), | loginname character varying(255), | "password" character varying(255), | joined timestamp without time zone, | CONSTRAINT t_user_pkey PRIMARY KEY (email) | ) | and a second table t_user_roles | CREATE TABLE t_user_roles | ( | t_user_email character varying(255) NOT NULL, | element integer, | CONSTRAINT fk8fc22a14c7001400 FOREIGN KEY (t_user_email) | REFERENCES t_user (email) MATCH SIMPLE | ON UPDATE NO ACTION ON DELETE NO ACTION | ) | element encodes which role a user is in. When I run seam generate-entities I get no errors or warnings | C:\seam-buch\seam\jboss-seam-2.0.0.GA>seam generate-entities | C:\seam-buch\jdk\jdk_1_5_0_12 | Buildfile:

The generated class TUserList defines a member tUser and a getter (getTUser). When I change the getter to gettUser. Please note the lowercase 't' in TUser. I get one step further. Now I get a similar error for class TUserRoleList. Making similar change fixes this problem too. Now the home screen of the application is rendered correctly. But selecting 'TUserRolesList' from the menu on the top of the page gives a similar error message as the the two before. Now property 'tUserEmail' cannot be found. See [img]http://www.seamguru.com/jbossforum/img/seamDBBug2.png[/img] See http://www.seamguru.com/jbossforum/img/seamDBBug2.png My questions are: Has anyone else seen this error? Why does the error message complain about 'tUserEmail' / 'tUser' as far as I can see 'tUser' / 'tUserEmail' is not used in the XHTML pages? Any response welcome!
