[jboss-user] [JBoss Seam] - NullPointer for SeamSelectItems config

[dave.rogers]

I'm getting the error:

java.lang.NullPointerException
  | 	at org.jboss.seam.selectitems.ui.UISeamSelectItems.isCache(UISeamSelectItems.java:64)
  | 	at org.jboss.seam.selectitems.ui.UISeamSelectItems.evaluateCacheKey(UISeamSelectItems.java:277)
  | 	at org.jboss.seam.selectitems.ui.UISeamSelectItems.isCacheEnabled(UISeamSelectItems.java:273)
  | 	at org.jboss.seam.selectitems.ui.UISeamSelectItems.getValue(UISeamSelectItems.java:193)
  | 	at org.apache.myfaces.trinidadinternal.renderkit.uix.SelectItemSupport.addSelectItems(SelectItemSupport.java:270)
  | 	at org.apache.myfaces.trinidadinternal.renderkit.uix.SelectItemSupport.getSelectItems(SelectItemSupport.java:90)
  | 	at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.SimpleSelectOneRenderer.encodeAllAsElement(SimpleSelectOneRenderer.java:255)
  | 	at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.FormElementRenderer.encode

When using the select items tag as follows:

<tr:selectOneChoice id="catalogue" value="#{itemManager.item.catalogue}">
  | 				  		<si:selectItems value="#{catalogues}" var="catalogue" label="#{catalogue.name}"/>
  | 						</tr:selectOneChoice> 

It was working fine just before, so it's probably something small.
