Seam-gen generated entity and @Embeddable class problem

[jlemoine]

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

Is name null in country for a new instance?

Ooops...

Works really better when the Country class initializes the name...
like:

// private Name name;
private Name name = new Name();

Since there were no explicit "null pointer exception", I didn't look that direction.

Anyway, sorry for spamming this forum with my crap questions, and:

Thanks!
