Now I tried with actionListener as well. But still I am getting the same
warning.
<h:selectManyListbox size="3" rendered="true" id="serviceTypes">
<f:selectItems value="#{hostInfoBean.serviceTypeItems}" />
<a4j:support event="onchange"
actionListener="#{hostInfoBean.changeServiceTypes}"
reRender="hostInfo:gateKeeperendPointReference" ajaxSingle="true"/>
</h:selectManyListbox>
WARNING: There are some unhandled FacesMessages, this means not every
FacesMessage had a chance to be rendered.
These unhandled FacesMessages are:
- hostInfo:serviceTypes: Validation Error: Value is not valid
I am using Myfaces 2.0. May be there is an issue or a missing step that we
need to configure before using a4j or valueChangeListener.
I googled this warning and I got the below source code for this warning.

But I didn't any other useful information.
