I use JBoss/Seam 1.0.0CR3. When I wrote a long EL name for accessing JavaBean's property. | javax.faces.FacesException: Value binding '#{chgWhereaboutsAction.groupSelectItems}'of UISelectItems | with component-path {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /chgWhereabouts.jsp] | [Class: javax.faces.component.html.HtmlForm,Id: _id0][Class: javax.faces.component.html.HtmlSelectOneMenu,Id: | groupId][Class: javax.faces.component.UISelectItems,Id: _id218]} does not reference an Object of type SelectItem, | SelectItem[], Collection or Map but of type : null | There was the error above. I changed JavaBean's @Name to chgWhereaboutsBB. It's a little bit shorter than before(chgWhereaboutsAction) And I run again and no error ocured. What happened ? Is there the limit of length for specifying componemt property ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964297#...
