I tried to setup a hibernate filter, enabled in components.xml, with a parameter.
I have tested 3 scenarii :

1. in hibernate filter, the parameter has type long, in the EL value in components.xml I inject a value of type Long : EL value result is always empty


2. in hibernate filter def, long parameter, and String as EL result value : exception wrong type for parameter


3. string as hibernte filter parameter and String as EL result value : OK !

So I have 2 questions :

• Is it a Seam or Hibernate problem ?


• Is it a EL bug ?

My components.xml code :

<persistence:filter name="hasRights" enabled="#{identity.loggedIn}">
  <persistence:name>hasRights</persistence:name>
  <persistence:parameters>
    <key>companyId</key>
    <value>#{companyId}</value>
  </persistence:parameters>
</persistence:filter>
<persistence:managed-persistence-context name="restrictedEntityManager"
  auto-create="true"
  persistence-unit-jndi-name="java:/appEntityManagerFactory">
  <persistence:filters>
    <value>#{hasRights}</value>
  </persistence:filters>
</persistence:managed-persistence-context>

The definition of the filter :

@FilterDefs(value={
  @FilterDef(name="hasRights", parameters={@ParamDef(type="string", name="companyId")})
})

The Filter :

@Filters(value={
    @Filter(
      name="hasRights", 
      condition="(company_id = :companyId)"
    )
  })
