[jboss-user] [JBoss Seam] - Design question with facelets

[UTDrew]

Hi,

I have a question about the proper way to design a project.  I have an entity that the user can create, search for, and edit.  

Creating the entity goes through a multi-page wizard.  This is managed via a stateful  session bean (WizardBean) with a conversation context and a jbpdl pageflow.  

Editing the entity is on a single page.  This is also managed via a stateful session bean (EditorBean).

In both of these beans I have the same variable name (ex: entity) with an @Out annotation.

Following the DRY principal, I have created a base class which contains the validation code and some other common ajax UI functions.  I'm using facelets to re-use the UI for each of these.  Because two different session/backing beans use these pages I created an alias variable and in the appropriate pages I use a c:set to set the variable's value before the ui:include tag.  Since both backing beans export the same variable name I have not created a similar variable for the bean that is being edited/created.

My question is whether this is a good design pattern or not.  I'm not sure if I should just be using one stateful bean with functionality for both create and edit and I'm not sure if it's okay for 2 different SFSB's to export the same variable name in a conversation scope (for the record the editing and creating should always happen in different conversations).

Thanks,

Drew
