strange problem with ajax4jsf and s:selectItems
Hi,
i'm getting a exception on my page and i have no clue why. the overall architecture is a little bit hard to explain so i'll try to do it in short and if you need more details please tell me.
I have have a few input fields within a a4j:region tag. if the value of a field changes all data is submitted to the bean and if the validation succeeds an object is created and added to a list. the list is in return outjected as datamodel and the table displaying the list is rerendered and the region of the input fields.
<a4j:region>
<h:panelGrid id="allocateArea" columns="2" columnClasses="label,input">
<h:outputLabel for="utilisationType" value="#{messages.utilisationType}:"/>
<h:panelGroup>
<h:selectOneMenu
converter="#{objectmanager.modeOfUtilisationConverter}"
id="utilisationType"
value="#{tcmanager.modeOfUtilisation}">
<f:selectItem itemLabel="" itemValue="#{objectmanager.nullModeOfUtilisation}" />
<s:selectItems value="#{tcmanager.modesOfUtilisation}"/>
<a4j:support event="onchange" reRender="addArea" limitToList="true" ajaxSingle="true"/>
</h:selectOneMenu>
</h:panelGroup>
<h:outputLabel for="allocatedAreas_numOfAreas" value="#{messages.amount}:"/>
<h:panelGroup>
<h:inputText
id="allocatedAreas_numOfAreas"
value="#{tcmanager.numOfAreas}">
<a4j:support event="onkeyup" requestDelay="50" reRender="addArea,errorPanel_allocatedAreas" limitToList="true"/>
</h:inputText>
... more input fields
</a4g:region>so, whenever something changes all data is submitted. from time to time i get an exception when i add table items:
