对一个 Primefaces 表进行排序，该表填充了来自集合的数据

Question

I'm having trouble getting the sorting to work in my PrimeFaces data table.

This is my.xhtml file:

<p:dataTable id="audiobooksTable" var="audiobook" value="#{audiobookListController.audiobooks}">
    <f:facet name="header">
        Audiobooks
    </f:facet>
    
    <p:column headerText="Audiobookname" sortBy="#{audiobook.title}" >
        <h:outputText value="#{audiobook.title}" />
    </p:column>

The arrows for sorting show up but clicking them has no effect.

audiobook.title has the datatype String . There are also other columns that I want to sort by (with data types int and double ) but those also don't work.

The AudiobookListController returns Collection<AudioBook> .

Any help would be greatly appreciated.

If you are using Primefaces 10 , try downgrading to Primefaces 8 , there is an issue with sortBy.
