我正在使用 icefaces 3.x 问题是当我第一次使用 shift+click 选择任何行时出现错误。ice:rowselector 标签的 value 属性给了我错误，这个标签放在第一列

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

当我第一次使用 shift+click 选择任何行时，错误如下

javax.faces.el.PropertyNotFoundException: javax.el.PropertyNotFoundException: //D:/Error Correction/WorkSpace/InstantInvoicing/WebContent/InstantInvoicing.xhtml @169,279 value="#{instantInvoiceDetails.highlighted}": Target Unreachable, identifier 'instantInvoiceDetails' resolved to null

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) {
                if (nwIid.isHighlighted()) {
                    commentstatus=false;
                    sumOfH += Integer.parseInt(nwIid.getNetChrgAmt());
                    System.out.println("--2-sumOfH--"+sumOfH);
                    getHighlightedInvoices().add(nwIid);
                    System.out.println(getHighlightedInvoices().size());
                    if(getHighlightedInvoices().size()==0)
                    {
                        commentstatus=true;
                    }
                    setSumOfHighRows(Integer.toString(sumOfH));                
                }             

            }
        }

    }
