Subject Re: label error
Date Mon, 19 Mar 2007 20:44:00 GMT
I don't know about the Seam selectItems tag, but the tomahawk one
looks similar, except that you have to specify a label and a value.

   	<t:selectItems value="#{selectItemsBean.carList}" var="Car"
itemLabel="#{Car.type}" itemValue="#{Car.color}" />

I haven't looked at the source, but I'd guess that an NPE on the
following line is due to a null label value.    Maybe you need to
somehow specify the individual labels in your Seam selectItems tag.

javax.faces.model.SelectItem.<init>(SelectItem.java:70)
