RichFaces rich:列和排序

问题描述

有谁知道如何正确地使用rich:columns标记动态启用在rich:dataTable上排序的列?

does anyone know how to properly enable sorting on a rich:dataTable with columns generated on the fly using rich:columns tag?

使用#{row [column]}这样的表达式设置sortBy对我不起作用.

Setting sortBy with an expression like #{row[column]} doesn't work for me.

我正在使用RichFaces 3.3.1GA.

I'm using RichFaces 3.3.1GA.

这里是例子:

<rich:dataTable id="table" value="#{localeHandler.locales}" var="row">
    <rich:columns value="#{localeHandler.columns}" var="column" sortBy="#{row[column]}" >
        <f:facet name="header">
            <h:outputText value="#{column}"/>
        </f:facet>
        <h:outputText value="#{row[column]}"/>
    </rich:columns>
</rich:dataTable>

而localeHandler.locales是一个ArrayList，而localeHandler.columns只是一个包含以下值的ArrayList:

whereas the localeHandler.locales is an ArrayList and localeHandler.columns is just an ArrayList containing the following values:

language, country, variant, displayName, displayLanguage, displayCountry, displayVariant

推荐答案

我发现此功能起作用的最后一个版本是3.3.0.CR1-自3.3.0.CR2起它就坏了.

I've found out that the last version where this feature worked was 3.3.0.CR1 - since 3.3.0.CR2 it's broken.
