<si:selectItems /> and selectMany

[fhh]

Hello!

I'm trying to use <si:selectItems /> together with <h:selectMany /> and it seems to be buggy.

@Name("Department")
@Scope(CONVERSATION)
public Class Department {

 private List<Employee> employees;

}

@Entity
public Class Employee {

 @Id
 private Integer id;
 private String name;

}

Now I want to do something like this:

<h:selectManyCheckbox value="#{department.employees}">

 <si:selectItems value="#{employee}" var="employee" label="#{employee.name}" cache="true" />

</h:selectManyCheckbox>

This does not work on the first try. I get a validation error - "Selected item cannot be loaded from persistence context." If I try again it works and the ArrayList is updated correctly. Is this a bug or I am doing something wrongly?

Regards

Felix

P.S.: All the "employees" have been persisted before and do have a valid id.

Please read the tips and troubleshooting section on the wiki. N.B. You would be better off using 1.1.6, s:selectItems and ec:entityConverter.

Hi Peter, Do you know which example in Seam 1.1.6 package demonstrates the use of s:selectItems and ec:entityConverter? Thank you.

The ui-example example demonstrates s:selectItems. As the entity converter is not currently in Seam, there isn't an example for it in Seam ;)
http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamEntityConverter - the dist for this contains an example directory - the directory is based upon the old SeamSelectItems example.

Thanks! I missed that.

I have already seen it but I can't switch at the moment as the project is in a testing phase. I will try it out during next development cycle.
