this is my *.xhtml

| xmlns:t="http://myfaces.apache.org/tomahawk"
| ......................
| <ga:responseActions>
| <id:listUsers target="#{users}" />
| </ga:responseActions>
| <h:selectOneMenu required="true" value="#{var['collection1']}">
| <t:selectItems value="#{users}" var="user" itemLabel="#{user.name}"
itemValue="#{user.name}" />
| </h:selectOneMenu>
|

exceptions.
