ListShuttle and validation
Hello,
I know that this problem was already discussed, but solution from those topics doesn't work in my situation....
So... Could you help me by some tips or something same, if possible? I will be greatly pleased.
Well, I have form:
<h:form>
<h:outputText value="Select Location" />
<h:selectOneMenu value="#{myBean.mainLocation}"
valueChangeListener="#{myBean.changeMainLocation}"
>
<f:selectItems value="#{myBean.locationsList}" />
</h:selectOneMenu>
<h:panelGroup rendered="#{myBean.isMainLocationExists}">
<br>
<rich:separator align="left" />
<br>
<rich:listShuttle sourceValue="#{myBean.locationsForCascading}" id="ls"
targetValue="#{myBean.cascadedLocations}" var="items"
sourceListWidth="180" targetListWidth="180"
sourceCaptionLabel=" "
targetCaptionLabel="Locations that cascade <br>through #{myBean.mainLocation}"
fastOrderControlsVisible="false" orderControlsVisible="false"
converter="LocationDataConverter">
<rich:column>
<h:outputText value="#{items.location}" />
</rich:column>
</rich:listShuttle>
<br>
<h:panelGroup styleClass="leftalignclass">
<h:commandButton value="Save"
action="#{myBean.saveChanges}"
styleClass="leftalignclass">
</h:commandButton>
</h:panelGroup>
</h:panelGroup>
</h:form>
with bean:
<a4j:keepAlive beanName="myBean" />
(faces-config:)
<managed-bean>
<description>MyBean</description>

When page is loaded slowly and we have enough time to send multiple request choosing several lines in h:selectOneMenu, we can see this message:
"Component _js_MainMenuPortlet__dp_2__MSRSMgmtPortlet_:j_id_jsp_566537391_0:viewMyBean:j_id_jsp_626996794_1pc6:ls has invalid value expression location=Clients Location"
about value location=Clients Location" for rich:listShuttle
And I have no idea how to avoid this.
Could you give me any advices please?
thank you in advance anyway.
