ND9中带有组合框的xpages数字转换器 [英] xpages number converter with combobox in ND9

问题描述

在Domino 9服务器上xpages的组合框中，无法将数字转换与numberConvert一起使用.这曾经在8.5服务器上工作.

I'm having trouble using number conversion with numberConvert in a combo box in xpages on a Domino 9 server. This used to work on the 8.5 server.

提交值时，我得到:验证错误:值无效

When I submit the values I get: Validation Error: Value is not valid

我还尝试使用"new javax.faces.model.SelectItem"填充值，但这没有任何区别.

I also tried to populate the values with "new javax.faces.model.SelectItem" but that didn't make any difference.

有人知道如何在ND9的组合框中使用数字吗?

Does anyone know how to use numbers in combo boxes in ND9?

以下是来源(在此示例中，我删除了所有不必要的内容):

Here is the source (I removed everything unneccesary for this example):

<xp:comboBox id="combo" value="#{viewScope.testfield}">
    <xp:this.converter>
        <xp:convertNumber type="number"></xp:convertNumber>
    </xp:this.converter>
    <xp:selectItem itemLabel="9" id="selectItem1" itemValue="9">
    </xp:selectItem>
    <xp:selectItems>
        <xp:this.value><![CDATA[#{javascript:var arr=new Array("0","1","2"); return arr;}]]></xp:this.value>
    </xp:selectItems>
</xp:comboBox>

<xp:message id="message1" for="combo"></xp:message>

<xp:button value="Label" id="button1">
    <xp:eventHandler event="onclick" submit="true"
        refreshMode="complete">
        <xp:this.action>
            <xp:save></xp:save>
        </xp:this.action>
    </xp:eventHandler>
</xp:button>

推荐答案

如果要在ComboBox中选择数字，则必须将comboBox的可能值定义为数字数组，而不是字符串.

If you want to select numbers in a ComboBox you have to define comboBox's possible values as an array of numbers, not strings.

<xp:this.beforePageLoad><![CDATA[#{javascript:viewScope.testfield = 1}]]></xp:this.beforePageLoad>

<xp:comboBox id="combo" value="#{testfield}">
    <xp:selectItem itemLabel="0" itemValue="${javascript:0}"></xp:selectItem>
    <xp:selectItem itemLabel="1" itemValue="${javascript:1}"></xp:selectItem>
    <xp:selectItem itemLabel="2" itemValue="${javascript:2}"></xp:selectItem>
</xp:comboBox>

如果值是作用域变量，则此示例可以完美地无需使用转换器.

This example works perfect without using a converter if the value is a scope variable.

如果条目数量灵活，可以同时使用Adibabu Kancharla的答案中所示的两种方式.

If you have a flexible number of entries you can use both ways shown in Adibabu Kancharla's answer.

数字转换器对于绑定到文档的数字字段是必需的.以下示例适用于 ND853 和 ND9.我必须添加 integerOnly ="true" :

The number converter is necessary for binding to a document's number field. The following example works for me in ND853 and ND9. I had to add integerOnly="true" though:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">
    <xp:this.data>
        <xp:dominoDocument var="document1" formName="NumberTest"
            action="editDocument"
            documentId="477FF8697EE50EDBC1257B710073DDE3">
        </xp:dominoDocument>
    </xp:this.data>
    <xp:comboBox id="combo" value="#{document1.Number}">
        <xp:selectItem itemLabel="0" itemValue="${javascript:0}"></xp:selectItem>
        <xp:selectItem itemLabel="1" itemValue="${javascript:1}"></xp:selectItem>
        <xp:selectItem itemLabel="2" itemValue="${javascript:2}"></xp:selectItem>
        <xp:this.converter>
            <xp:convertNumber type="number" integerOnly="true"></xp:convertNumber>
        </xp:this.converter>
    </xp:comboBox>
    <xp:message id="message1" for="combo"></xp:message>

    <xp:button value="Label" id="button1">
        <xp:eventHandler event="onclick" submit="true"
            refreshMode="complete">
            <xp:this.action>
                <xp:save></xp:save>
            </xp:this.action>
        </xp:eventHandler>
    </xp:button>
</xp:view>
