私は icefaces 3.x に取り組んでいます。問題は、Shift キーを押しながらクリックして初めて行を選択したときにエラーが発生することです。ice:rowselector タグの value 属性でエラーが発生しています。このタグは最初の列内に配置されています
<ice:rowSelector
value="#{instantInvoiceDetails.highlighted}"
enhancedMultiple="true"
selectionListener="#{instantInvoice.selectListener}"
toggleOnInput="false"
preStyleOnSelection="true">
</ice:rowSelector>
初めてシフト+クリックして行を選択すると、エラーは次のようになります
