primefaces: DataTable: manual assigning selection attr does not set internal selection state in DataTable component

Describe the defect If I use a DataTable with “multiViewState=true”, I can not set the selection using a Command Component like it is described within the Primefaces documentation (see here).

If I set the selection like that, the value in the data model is updated but not populated to the DataTableState. So when “DataTable.restoreMultiViewState()” is called afterwards the old selection is set, highlighted and overrides also the value within the data model.

This does not happen if the selection is set by clicking the target row because then the “SelectionFeature.decode(FacesContext context, DataTable table)” is called which updates the DataTableState too.

Reproducer This can be reproduced by creating the case like it is in the linked showcase (see description) but you need to set the “multiViewState” attribute to “true”, the “selectionMode” to “single” and the “disabledSelection” to “false”. It can be reproduced with prime faces 10 and 11.

This would look like that:

<p:dataTable var="car" value="#{carBean.cars}" selectionMode="single" multiViewState="true" disabledSelection="false"> <p:column> <p:commandButton value="Select"> <f:setPropertyActionListener value="#{car}" target="#{carBean.selectedCar}" /> </p:commandButton> </p:column> ...columns </p:dataTable>

Environment:

• PF Version: 11.0.1
• PF Theme: Diamond
• JSF + version: MyFaces 2.3.8
• Affected browsers: ALL

Expected behavior My expected behavior would be like that, it does not matter if I select the row by button or by clicking on the target row itself.
