Entity Converter - "value is not valid"
Just a question, whether this is a bug or not. The documentation (look for s:convertEntity) says
If you want to use more than one entity manager with the entity converter, you can create a copy of the entity converter for each entity manager in components.xml
You should then use <f:converter converterId="myEntityConverter" /> instead of <s:convertEntity/>.
I have two entity managers, but I only want to use one with the entity converter. So I used the standard notation.
The problem: whenever I selected an item in my selectOneMenu I received a validator message value is not valid
. It took a long time to figure out the reason for the problem.
Could perhaps the documentation be updated, to be a little bit more precise? The main issue for me is that it works for forms where I use EntityHomes, but does not work for another form (shown below)
There are two things that may deviate from the standard in the application and this other form:
- I use hibernate sessions. The second hibernate session is only used in a special case (unrelated to the form where it does not work).
- The form in question uses two s:selectItems inside a h:selectOneMenu
components.xml:
<persistence:managed-persistence-context name="entityManager"
auto-create="true"
persistence-unit-jndi-name="java:/amonEntityManagerFactory" />
<factory name="hibernateSession" scope="STATELESS" auto-create="true"
value="#{entityManager.delegate}" />
<persistence:managed-persistence-context name="queryEntityManager"
auto-create="true"
persistence-unit-jndi-name="java:/amonEntityManagerFactory" />
<factory name="querySession" scope="STATELESS" auto-create="true"
value="#{queryEntityManager.delegate}" />EntityHome-based form (works with s:convertEntity)
