PrimeFaces 10: sortBy not working in p:dataTable

I migrated from PrimeFaces 6.1 to 10.0.0 and now sortBy of every p:dataTable I have in my project doesn't work.

An example of my p:dataTable:

<p:dataTable widgetVar="truckListTable" id="truckListTable" var="truck" value="#{truckList.trucks}"
    sortBy="#{truck.code}" sortMode="single" filteredValue="#{truckList.filteredTrucks}" paginator="true"
    paginatorPosition="top" rows="20" paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}">
    ...
    <p:column sortBy="#{truck.plate}" filterBy="#{truck.plate}" filterMatchMode="contains">
        <h:outputText value="#{truck.plate}" />
    </p:column>
    ...
</p:dataTable>

I defined truck variable as follow in my bean truckList:

private List<Map> trucks;

public List<Map> getTrucks() {
    return trucks;
}

public void setTrucks(List<Map> trucks) {
    this.trucks = trucks;
}

My problem is when I click the column header, the table rows are not sorted.

filterBy works fine, but sortBy no. Where am I doing wrong?

To me issue was solved by wrapping dataTable in the form tag:

    <h:form id="applicationsForm">
        <p:dataTable id="applicationsTable" var="applicationValue" value="#{applicationsListBean.applications}" sortMode="single" >

Had the same issue, which cost me several hours.

Stumbled across this thread: https://github.com/primefaces/primefaces/issues/7232#issuecomment-822529549

Changing javax.faces.STATE_SAVING_METHOD to server fixed the issue.

Try adding/replacing in your web.xml

  <context-param>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>server</param-value>
  </context-param>

Documentation states that sortBy expects a single or a collection of SortMeta. This is also mentioned in the from 8 to 10 migration guide.

So, either provide a SortMeta from your bean or simply add sortOrder to the p:column of the "code".

SortMeta can be created like:

SortMeta.builder().field("code").order(SortOrder.ASCENDING).build();
