[jboss-user] [JBoss Seam] - Re: EntityHome for nested entity CRUD?

[kingcu]

Converter is not needed for id, since it's a Long. Now I can pass the id from the page to Home and use getEntityManager().find() to load the parent business entity and wire it up with the child. But we are kind of falling back to the old style, I was hoping that there be a way to inject the parent or its home into the child's Home. It looks to me that Seam's bijection is not general or flexible enough to cover this specific situation.

And now, I am getting into a new problem: the parent's Home object does not get cleaned up when creating the child, so the edit page for creating the child still shows values from the parent and thus the wrong set of buttons. Here is how my page looks like:

<ui:define name="body">
  |     
  |     <h:messages globalOnly="true" styleClass="message" id="globalMessages"/>
  | 
  |     <h:form id="business" styleClass="edit">
  |     
  |         <rich:panel>
  |             <f:facet name="header">Edit Business</f:facet>
  | 
  |             <s:decorate id="nameDecoration" template="layout/edit.xhtml">
  |                 <ui:define name="label">name</ui:define>
  |                 <h:inputTextarea id="name"
  |                                cols="80"
  |                                rows="3"
  |                               value="#{businessHome.instance.name}"/>
  |             </s:decorate>
  | 
  |             <s:decorate id="descriptionDecoration" template="layout/edit.xhtml">
  |                 <ui:define name="label">description</ui:define>
  |                 <h:inputTextarea id="description"
  |                                cols="80"
  |                                rows="3"
  |                               value="#{businessHome.instance.description}"/>
  |             </s:decorate>
  |         
  |             <div style="clear:both">
