Izpack：验证程序不起作用？ [英] Izpack: Validator doesn't work?

问题描述

我的 UserInputSpec.xml文件中有一个字段描述。

I have a field description in my "UserInputSpec.xml" file.

<field type="radio" variable="selected.source" >
        <description align="left" txt="Please select TBPAPIIntegrator data source:" id="combo.text" />
        <spec>
            <choice txt="IMKB Server"      id="combo.item.imkb"     value="imkb"/>
            <choice txt="Exernal Database" id="combo.item.database" value="db"/>
        </spec>
        <validator class="com.j32bit.installer.validator.SelectSourceValidator" txt="Please select one source!" >
            <param name="selected.source" value="${selected.source}"/>
        </validator>
    </field>

这是我的Validator类：

and this my Validator class:

package com.j32bit.installer.validator;

import java.util.Map;
import com.izforge.izpack.panels.ProcessingClient;
import com.izforge.izpack.panels.Validator;

public class SelectSourceValidator implements Validator{

    @Override
    public boolean validate(ProcessingClient client) {

        Map<String, String> params = client.getValidatorParams();

        if( params.get("selected.source").equals("imkb")
                ||  params.get("selected.source").equals("db"))
            return true;

        return false;
    }
}

变量减速度也如下 Installer.xml中所示：

Also variable deceleration as below in "Installer.xml":

<variables>
    <variable name="selected.source" value="" />
</variables>

单选按钮未选中。如果我单击下一步按钮安装程序后仍未选择按钮，则继续下一页，并且验证不起作用。

Radio buttons comes unselected. While buttons still unselected if I click "next" button installer continuous the next page and validation does not work.

请帮助！
预先感谢。

Please help! Thanks in advance.

推荐答案

似乎在< dynamicvariables>中声明了一个变量。 < / dynamicvariables> 或< variables>< / variables> 根本不起作用。相反，您可以仅将变量名称写入字段，并且可以在安装程序中的任何位置使用和引用该变量名称。




我还从UserInputPanelSpec.xml中的字段声明中删除了验证器，并将其移到Installer.xml中的面板声明中。

It seems like declaring a variable in <dynamicvariables></dynamicvariables> or in <variables></variables> does not work at all. Instead you can just write a variable name to a field and it can be used and referenced in anywhere in installer.

I also removed validator from field declaration in UserInputPanelSpec.xml and moved it to panel declaration in Installer.xml.

Installer.xml：

Installer.xml:

<panels>
    <panel classname="UserInputPanel" id="select.source" >
        <validator classname="com.j32bit.installer.validator.SourceValidator"/>
    </panel>
</panels>

UserInputPanelSpec.xml：

UserInputPanelSpec.xml:

<!-- SELECT SOURCE PANEL  -->
<panel id="select.source">
    <field type="radio" variable="selected.source" >
        <description align="left" txt="Please select TBPAPIIntegrator data source:" id="radio.text" />
            <spec>
                <choice txt="IMKB" id="radio.item.imkb" value="imkb" />
                <choice txt="Exernal Database" id="radio.item.db" value="db" />
            </spec>
    </field>
</panel>

现在它可以正常工作了。

Now it is working with no problem.
