Question

我希望在转换器发生故障时更改错误消息的占位符。

一般情况下，我使用IceFaces组件ice：selectInputDate和转换器f：convertTimeDate。

<ice:selectInputDate ...>
<f:convertDateTime pattern="..." timeZone="..."/>
</ice:selectInputDate>

当'convertTimeDate'失败时，会显示自定义错误消息，如

javax.faces.converter.DateTimeConverter.DATE=The value {0} in field {2} is wrong.
javax.faces.converter.DateTimeConverter.DATE_detail=The value {0} in field {2} is wrong.

有三个占位符，{0}，{1}，{2}：

DATE_ID

public static final java.lang.String DATE_ID

The message identifier of the FacesMessage to be created if the conversion to Date fails. The message format string for this message may optionally include the following placeholders:

    {0} replaced by the unconverted value.
    {1} replaced by an example value.
    {2} replaced by a String whose value is the label of the input component that produced this message.

问题是IceFaces将标签从“labelId”更改为“pageform：labelId”。是否可以为{2}使用自定义字符串或使用自定义字符串添加新的占位符{3}？
