Shift +单击多个行选择

Question

我正在研究icefaces 3.x. 问题是当我第一次使用shift +点击选择任何行时，我得到错误。 ice：rowselector标签的value属性给出了错误，此标记放在第一列

中

<ice:rowSelector 
     value="#{instantInvoiceDetails.highlighted}"  
     enhancedMultiple="true"    
     selectionListener="#{instantInvoice.selectListener}"   
     toggleOnInput="false"    
     preStyleOnSelection="true">
</ice:rowSelector>

当我第一次使用shift +点击选择任何行

时，错误如下

以下是InstantInvoiceDetails.java的代码片段

 private boolean highlighted=false;

        public boolean isHighlighted() {
        return highlighted;
    }

    public void setHighlighted(boolean highlighted) {

        this.highlighted = highlighted;
     }

InstantInvoice.java的代码片段

    public void selectListener(RowSelectorEvent event) {

            if (sumOfHighRows == null || sumOfHighRows.equals("")) {
                setSumOfHighRows("0");
            }
            //System.out.println(" Enhanced multiple ?"+row.isEnhancedMultiple());
            commentstatus=true;
            System.out.println("size is "+getHighlightedInvoices().size());
            setSumOfHighRows("0");
            getHighlightedInvoices().clear();

            int sumOfH = Integer.parseInt(getSumOfHighRows());
            System.out.println("--1-sumOfH--"+sumOfH);
            for (InstantInvoiceDetails nwIid : invoices) {
