PrimeFaces dynamic columns sorting is not working

[jhula]

Hello, I have a problem with sorting of the dynamic columns after upgrade to PF10. In PF8 it was working. I'm sorting over the string array, but the sort buttons are not displayed in the datatable.

Code: Select all

<p:dataTable id="table" var="item" widgetVar="table"
	value="#{bean.items}" rows="50"
	paginator="true" pageLinks="4"
	paginatorTemplate="{RowsPerPageInputText} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {CurrentPageReport} {Exporters}"
	rowsPerPageTemplate="50" paginatorPosition="bottom" sortMode="single">

	<p:columns value="#{bean.columns}" var="column"
		columnIndexVar="colIndex" headerText="#{column.header}" sortBy="#{item.values[column.index]}">
		<h:outputText value="#{item.values[column.index]}" rendered="#{!column.dateValue}" />
		<h:outputText value="#{item.changeDate.time}" rendered="#{column.dateValue}"/>
	</p:columns>
</p:dataTable>

Items displayed in the data table

Code: Select all

public class Items {
	protected String[] values;
	protected List<DataVO> extraData;
	protected Calendar date;
	// GETTERS
}

Columns model

Code: Select all

public class ColumnModel {
	protected String header;
	protected String property;
	protected int index;
	protected boolean dateValue;
	// GETTERS
}
