Just a guess, try
<t:updateActionListener value="#{displaybean.alarmTableId}"
property="#{displaybean.selectedTable}" />
instead of :
<t:updateActionListener value="#{displaybean.getAlarmTableId}"
property="#{displaybean.selectedTable}" />
The value attribute is referencing the property, not the getter.

Hi,
I am trying to integrate my JSF pages with an existing JSP application. I
have edited a JSP and removed most of JSP stuff in it and added JSF. I
added
a commandButton as follows:
<h:commandButton value="Set table alarms" onclick="javascript:alert('hi')"
styleClass="tdButtonHolder">
<t:updateActionListener value="#{displaybean.getAlarmTableId}" property="#{
displaybean.selectedTable}" />
</h:commandButton>
However, when I click this button, I do get the alert and then the
exception
below.

Does anybody have any idea what is wrong?
I am using JBoss 4.0.3 SP1 with same libs in jsf-libs and WEB-INF/lib of my
application's war file.
Thanks,
Aneesha
