Hi, I'm a total newbie with Seam/Hibernate, and I encounter a problem as I play with my first Seam-gen generated Entity. (1.1.0CR1 + adequate jbossAS) I would like to create a Country entity, that has an ISO code, an Int'l spelling name and a local name. Just like "JP, Japan, ??". Since I plan to have a lot of stuff with this kind of Int'l / local names, I've tuned the Country class like this : @Entity(country) | public class Country ... { | ... | // private String name; | private Name name; | ... | | public Name getName(){ | return this.name; | } | public void setName(Name name){ | this.name = name; | } | } This seems OK regarding Hibernate's ref. manual. Then, I wrote the following Name class : @Embeddable | public class Name{ | private String local; | private String intl; | | // getters and setters | ... | } I've also adapted the default countryList.xhtml and country.xhtml accordingly. So far so good. Now I seam-explode my project and start jbossAS. I access the default countryList page (empty), click "Create", type in the data, and save. The page redraws and shows beside the 2 names (translated from the French error messages) : "intl" : error while updating the data "local" : error while updating the data So, I manually create a row in the DB (MySQL), and go back to the country list. It displays the new row. Good. So why can JSF/SEAM/Hibernate access the country.name.local data in countryList.xhtml, but fails to update countryHome.instance.name.local in country.xhtml ? BTW, there's just no error message in jboss's console. I have tried without the Name class, and works perfectly. But I'd prefer the @Embeddable class solution. Any idea ? Thanks for your help. It would be cool I get it to work before I go on exploring entity associations... Regards, Jean View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990440#...
