Izpack：验证器不起作用？
我的“UserInputSpec.xml”文件中有一个字段描述。
<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="${selected.source}"/>
</validator>
</field>
这是我的 Validator 类：
package com.j32bit.installer.validator;
import java.util.Map;
import com.izforge.izpack.panels.ProcessingClient;
import com.izforge.izpack.panels.Validator;
public class SelectSourceValidator implements Validator{
@Override
public boolean validate(ProcessingClient client) {
Map<String, String> params = client.getValidatorParams();
if( params.get("selected.source").equals("imkb")
|| params.get("selected.source").equals("db"))
return true;
return false;
}
}
“Installer.xml”中的变量减速度也如下：
<variables>
<variable name="selected.source" value="" />
</variables>
单选按钮未选中。虽然按钮仍未选择，但如果我单击“下一步”按钮，安装程序会继续下一页，并且验证不起作用。
请帮忙！ 提前致谢。
I have a field description in my "UserInputSpec.xml" file.
<field type="radio" variable="selected.source" >
<description align="left" txt="Please select TBPAPIIntegrator data source:" id="combo.text" />
<spec>
<choice txt="IMKB Server" id="combo.item.imkb" value="imkb"/>
<choice txt="Exernal Database" id="combo.item.database" value="db"/>
</spec>
<validator class="com.j32bit.installer.validator.SelectSourceValidator" txt="Please select one source!" >
<param name="selected.source" value="${selected.source}"/>
</validator>
</field>
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;
}
}
Also variable deceleration as below in "Installer.xml":
<variables>
<variable name="selected.source" value="" />
</variables>
Radio buttons comes unselected. While buttons still unselected if I click "next" button installer continuous the next page and validation does not work.
Please help!
Thanks in advance.

似乎在
我还从 UserInputPanelSpec.xml 中的字段声明中删除了验证器，并将其移至 Installer.xml 中的面板声明中。
Installer.xml：
UserInputPanelSpec.xml：
现在可以正常工作了。
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:
UserInputPanelSpec.xml:
Now it is working with no problem.
对于字段，如果您在规范中包含验证器元素会有所帮助：
For field, it can help if you include validator element inside the spec one:
