I get a nullpointerexception when i move the select box back to the item that
is "noSelectionLabel". When I select a valid entry inside the drop down, it
works OK. But when we go back to resetting it by selecting the
noSelectionLabel, it pops the following error.
Is this a bug?
| <h:selectOneMenu id="actionSelected1" value="#{voiceMenus.actionSelected1}"
>
| <a4j:support event="onchange"
actionListener="#{voiceMenus.onDropdown1Change}" reRender="drop0"
| limitToList="true" ignoreDupResponses="true" ajaxSingle="true"
/>
| <s:selectItems var="s_items0" value="#{voiceMenus.action}"
noSelectionLabel="[Select Step]" />
| </h:selectOneMenu>
|
| <a4j:outputPanel id="drop0" >
| <h:inputText value="#{voiceMenus.inputcustom1}"
rendered="#{voiceMenus.iscustom1}"/>
| </a4j:outputPanel>
stack trace is as follows
