Tss... who uses IE7? ;-)

Thank's for the correction though...

how does it react to dropping the convertEntity and using

<s:selectItems value="#{roleList.resultList}" var=role label="#{role.name}" itemValue="#{role.id}" />  

BTW, shouldn't it be value="#{...}". Or do the quotes matter?

54% of the known world and 5.4% of the nerds. I must confess that I do, mostly since that is what our customers mostly have standardized on and I don't feel like running two browsers all the time.

I haven't bothered to file a JIRA that e.g the tag box renders weird on IE8 beta :-).

I've had problems with selectManyCheckBox and s:selectItems. Are you getting an error messages that says something like Cannot coerce to type?

If so change your mapping to EAGER. The original forum post was this one

Hope this helps.

You can't back a JSF <h:selectXXX /> with a Set - it must be a List or an array.

Even with a List you may still get intermittent coerceToType errors unless you set your mapping to EAGER. Ironically this reoccurred in my application yesterday after not seeing it for about 5 months.

Note that the coerceToType error is now fixed with the latest JSF libs (1.2_08) : JIRA

Stan wrote up some quick instructions on upgrading your version of JSF to 1.2.08 - http://wiki.jboss.org/wiki/Wiki.jsp?page=UpgradeToMojarra1_2_08

There are some little differences in how JSF 1.2_08 renders the page. For instance it seems a bit tighter on passing through 'illegal' (or just immoral?) attributes.

For instance border in h:graphicImage. It used to pass it through even though it's not actually a 'proper' attribute. Now it doesn't. No big deal but worth being aware of.

I found a nice way to convert sets to lists using sets in jsf

might seem familiar to pete :)

Hi,

I post my own question here, because it seems to me that it's the same kind of problem. I'm using Seam 2.0.0 within JBoss 4.2.2. I'm trying to set values for a many2many relationship using selectManyCheckbox component, and keep having a conversion error when doing so (via a JSF message).

As a side note, I'm using a managed Hibernate session, and cannot / do not want to switch to an EJB entity manager.

Here is the component declaration (xhtml):

<h:selectManyCheckbox id="roles" value="{user.roles}">

     <s:selectItems value="{roleList}" var="role" label="#{role.rolename}" />

</h:selectManyCheckbox>

Here is the backing bean (having DbEntity implementing equals() and hashcode(), of course):

@Entity

@Name("user")

@Scope(SESSION)

public class User extends DbEntity

{

    private Set<Role> _roles;


    (...)


  /**

   * @hibernate.many-to-many

   *       column="ROLE_FK"

   *       class="Role"

   * @hibernate.key

   *           column="UTILISATEUR_FK"

   *           not-null="true"

   * @hibernate.set

   *           cascade="save-update"

   *           access="property"

   *           table="ROLE_UTILISATEUR"

   *           lazy="false"

   */

    public Set<Role> getRoles() {

         return _roles;

    }

     

  /**

    */

    protected void setRoles(Set<Role> roles) {

         _roles = roles;

    }

     

}

At rendering time, all is ok : my checkboxes appear with adequate values selected. But when I try to save the user (having modified anything or not), I've got the following message: Conversion Error setting value '...' for '{user.roles}'

I've tried the following:

1. using s:convertEntity with my hibernate session, but the EntityConverter is not initialized, because it has no session attribute (as I understood it, it is designed to work with EJB entity manager only)

2. define my own converter implementing javax.faces.convert.Converter for the Role entity. The getAsString method was called ok, but getAsObject was never called. I think I configured it ok in selectManyCheckbox, but maybe I made some mistake.

Nothing seems to work. Could anybody help me or give me some advice on this subject ?

Thanks
Thom'
