> Project: MyFaces
> Type: Bug
> Versions: 1.0.9 beta
> Environment: Windows XP SP2
> Reporter: Whitney Hunter
> Priority: Critical
> Attachments: _SharedRendererUtils.java, _SharedRendererUtils.java
> 
> I believe that this is a new bug in 1.0.9. It seems to not exist in 1.0.8.
> When I have jsp code like this:
> <f:view>
> <h:form>
> <h:panelGrid columns="1">
> <h:selectManyListbox>
> <f:selectItem itemLabel="one" itemValue="one" />
> <f:selectItem itemLabel="two" itemValue="two" />
> <f:selectItem itemLabel="three" itemValue="three" />
> <f:converter converterId="converter" />
> </h:selectManyListbox>
> <h:commandButton value="submit"
> actionListener="#{controller.submit}" />
> </h:panelGrid>
> </h:form>
> </f:view>
> I get a NullPointerException when I submit the form without selecting anything in \
> the list box (no problem when a selection is made). Here is the stack trace:
