Sven Rottstock commented on TRINIDAD-993:
-----------------------------------------
It seems to be a bug in SimpleSelectOneRenderer.
A work-around for this issue is to set the submitted value to an empty String.
Here is a short example:
<tr:selectOneListbox id="myOptions" label="Items:" value="#{bean.item}"
autoSubmit="true">
<!-- entries goes here... -->
</tr:selectOneListbox>
<tr:commandButton text="Delete Selected Item"
actionListener="#{bean.deleteItem}"/>
public class Bean
{
public void deleteItem(ActionEvent event)
{
// your delete stuff goes here
deleteSelectedItem();
// now the work-around
UIXSelectOne uiComp = (UIXSelectOne)FacesContext.getCurrentInstance()
.getViewRoot().findComponent("myOptions");
RequestContext().getCurrentInstance().addPartialTarget(uiComp);
uiComp.setSubmittedValue("");
}
}
> <tr:selectOneListbox> and <tr:selectOneChoice> throw on empty map

> Environment: jsf-1.2_07-b03-FCS
> Reporter: Paul van Rossem

> When the last item in a selectOneListbox is removed the renderer throws. But
> an empty list should be allowed.
> Also the exception message makes no sense (submittedValue's index "0" should
> be between "0" and "-1", see below).
> The same holds for selectOneChoice.
