Xpages Binding to edit control in a repeat

问题

I'm a problem understanding how to do dynamic binding to a edit control. The backend from has fields fItem01 fItem02... fPD01 fPD02.. fRQR01 fRQR02.. I can get the values for all the fields but having been able to defined the binding for edit control.

I've read all the posting on this subject but haven't figure out what I'm doing wrong. Also tried using a custom control with a property for the binding but that didn't work either.

Thanks for any help on this Bob

As you know which fields you want to put into the repeat control you can calculate the fieldNames in inner repeat block completely with

javascript:["fItem"+rowItem,"fPD"+rowItem,"fRQR"+rowItem]

and then use them in edit control's value EL #{document1[fieldName]}.

<xp:repeat
    id="repeat2"
    var="rowItem"
    indexVar="indexVar">
    <xp:this.value><![CDATA[#{javascript:["01", "02", "03"]}]]></xp:this.value>
    <xp:tr>
        <xp:repeat
            id="repeat3"
            var="fieldName">
            <xp:this.value><![CDATA[#{javascript:["fItem"+rowItem,"fPD"+rowItem,"fRQR"+rowItem]}]]></xp:this.value>
            <xp:td>
                <xp:inputText
                    id="inputText2"
                    value="#{document1[fieldName]}">
                </xp:inputText>
            </xp:td>
        </xp:repeat>
    </xp:tr>
</xp:repeat>
