[jboss-user] [JBoss Seam] - Re: Foreign Keys and changing Seam Gen templates

[damianharvey]

I totally misunderstood what Hibernate was trying to do there. I get it now.

What I was really after was the <si:selectItems> and for those looking it's all detailed here: http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamSelectItemsNewDesign

The only problem I'm now facing is that the si:selectItems doesn't seem to want to play nice with the EntityHome that Seam Gen uses on all Create/Edit pages. This is covered in this thread: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4008752#4008752

Also for anyone interested I made a change to the edit.xhtml.ftl template to include si:selectItems for ManyToOne fields:

  | <#elseif c2h.isManyToOne(property)>
  | <#assign parentPojo = c2j.getPOJOClass(cfg.getClassMapping(property.value.referencedEntityName))>
  | <#assign parentPageName = parentPojo.shortName>
  | <#assign parentName = util.lower(parentPojo.shortName)>
  | 
  |                     <tr class="prop">
  |                         <td class="name">${property.name}</td>
  |                         <td class="value">
  |                             <s:decorate>
  | 				<h:selectOneMenu value="${'#'}{${homeName}.instance.${property.name}}">
  | 				    <si:selectItems value="${'#'}{${parentName}SelectList.resultList}" var="${parentName}" label="${'#'}{${parentName}.${parentPojo.identifierProperty.name}}"/>
  | 				</h:selectOneMenu>
  |                             </s:decorate>
  |                         </td>
  |                     </tr>
  | 
This goes between the last 2 </#if> which are before the first </#foreach>. I also deleted the association stuff after the actionButtons. 

You still have to configure the project to handle si:selectItems and configure the components.xml to have the relevant queries; eg:

  | <framework:entity-query name="countryCodeSelectList" ejbql="select c from CountryCode c" /> 
  | 

Hope this helps someone.

Cheers,

Damian.
