Hi!
Since migrated my application to JSF 2 I'm no able to persist an empty to
null converted value in the database. The values passed in
managedBean.setModel(model) are empty strings for example again. I'm looking
for a reason of this behaviour for a few days now and would be happy, if
anybody can help me. Here are some snippets of my code:
<h:form id="editAlbum">
...
<h:inputText id="year"
value="#{albumDetailBean.album.year}"></h:inputText>
<h:commandButton action="#{albumDetailBean.save}"
value="#{msg.buttonSave}"></h:commandButton>
</h:form>
@Entity
public class Album {
...
@Column
Integer year;
...
}
@ManagedBean
@SessionScoped
public class AlbumDetailBean {
@ManagedProperty(value="#{albumService}")
private AlbumService albumService;
private Album album;
public static AlbumDetailBean getInstance() {
FacesContext fc = FacesContext.getCurrentInstance();
return (AlbumDetailBean) fc.getApplication().evaluateExpressionGet(fc,
"#{albumDetailBean}", AlbumDetailBean.class);
}
public String save() {
// At this point, album.year is Integer(0) instead of null...!
if (album.getId() == null)
albumService.insert(album);
else
albumService.update(album);
return "success";
}
public Album getAlbum() {
return album;
}
public void setAlbum(Album album) {
this.album = album;
}
}
I've tried to implement an empty string to null converter and git the same
behaviour. I've even tried the new
javax.faces.INTERPRET_EMPTY_STRING_SUBMITTED_VALUES_AS_NULL property.
Without success. :-(
