1. Re: s:convertEntity Setup with selectManyCheckbox
nimo22 Jun 30, 2008 1:19 PM (in response to nimo22)I use also a Seam managed transaction..
Before I tried to use this:
<h:selectManyCheckbox value="#{entityBean.choices}"> <s:selectItems value="#{selectableList}" var="s" label="#{s.description}" itemValue="#{s.id}"/> </h:selectManyCheckbox>
but I refer to an entityBean and its property 'choices' is declared as follows
private Set<Choices> choices = new HashSet<Choices>();
So u see its a relationship to the EntityBean 'Choices'. So when I use the converEntity it should be cast to selectItems and give the selected Items as a Set..but this does not work. Why? How can I solve that?

2. Re: s:convertEntity Setup with selectManyCheckbox
nimo22 Jun 30, 2008 1:31 PM (in response to nimo22)Have forgot to say that:
When I use s:selectItems with s:convertEntity:
<s:selectItems value="#{selectableList}" var="s" label="#{s.description}" itemValue="#{s.id}"/> <s:convertEntity/>
then the Error:
Not an entity class: java.lang.Integer
occurs.
The itemValue
s.id
is indeed a java.lang.Integer in my entityBean which I obtain from the list selectableList:@Factory("selectableList") public List <SelectItem> getSelectableList() { return entityManager.createQuery("from EntityBean s").getResultList(); }

4. Re: s:convertEntity Setup with selectManyCheckbox
nimo22 Jun 30, 2008 3:12 PM (in response to nimo22)I want to use s:convertEntity and my setup is right. I set it up in components.xml:
<component name="org.jboss.seam.ui.EntityConverter"> <property name="entityManager">#{entityManager}</property> </component>
and injected it with entityManager.
But I get the following problem:
