Hi Werner,
Yes, you are right. But I still cannot get the values in my backing
bean.
Jsp code:
<t:commandLink value="Add Reminders" styleClass="linkClass"
action="#{reminderController.showAddReminderScreen}"
actionListener="#{breadCrumbNavigatorBean.updateBreadCrumb}"
rendered="#{!physicianHomeController.showRemindersMoreLink}">
<t:updateActionListener
property="#{breadCrumbNavigatorBean.participant.displayText}"
value="#{msg['nav.msg.remiders']}"/>
</t:commandLink>
BreadCrumbNavigator.java (managed bean named as per config file is
breadCrumbNavitatorBean)
private BreadCrumbParticipant participant = null;
public BreadCrumbParticipant getParticipant() {
if (null == participant) {
participant = new BreadCrumbParticipant();
}
return participant;
}
And there are setter method as well.
Now when I access participant in the action listener method
-updateBreadCrumb, then the participant itself is not null but the
displayText property set using t:updateActionListener is null.
Any ideas what is going wrong here?
Regards,
Madhav
