[jboss-user] [JBoss Seam] - h:selectManyCheckbox for ManyToMany relationship

Hello, Here is my entity model: | Module | |-- name | Permission | |-- Module | |-- name | Role | |-- Permissions | |-- name | When I want to provide a front-end to edit Role information I do something like this and everything works: | <h:form> | <h:inputText value="#{role.name}"/> | | <h:selectManyCheckbox value="#{role.permissions}"> | <s:selectItems value="#{permissions}" var="p" label="#{p.name}"/> | <s:convertEntity/> | </h:selectManyCheckbox> | | <h:commandLink action="#{roleHome.persist}" value="Save"/> | </h:form> | The problem here is that all check boxes for permissions are grouped together. If you look at the entity model you will see that each permission belongs to a module. So I wanted to show check boxes grouped by module name. I tried something like this but it didn't work: | <h:form> | <h:inputText value="#{role.name}"/> | | <h:dataTable value="#{modules.resultList}" var="m"> | <h:column> | #{m.name} | | <h:selectManyCheckbox value="#{role.permissions}"> | <s:selectItems value="#{m.permissions}" var="p" label="#{p.name}"/> | <s:convertEntity/> | </h:selectManyCheckbox> | </h:column> | </h:dataTable> | | <h:commandLink action="#{roleHome.persist}" value="Save"/> | </h:form> | The page looks exactly as I wanted it to. It's just the state of check boxes doesn't get persisted. I guess it's because "name" element of HTML check box also gets a portion of it from h:dataTable. Any suggestions?
