DataTable: selected item remains current, even after building a new data source

[HolgerSuhr]

I use a data table for showing selected items. The table is reused for multiple selections.

When another selection is started, the data collection (ArrayList) is rebuilt and the item holding
the current selected row is set to null.

The data table shows a selected row if the rowKey of any previous selection can be found in this list.

It is not sufficient to set the variable holding the selection to null.
I have to set this variable to a dummy value to clear the selected row in my new data table.

Environment:

• PF Version: 10.0.0
• Mojarra 2.3.14

Expected behavior
With building a new data source and clearing the current-row-item, there should not be shown a selected row.

Example XHTML

  <h:form>
    <p:dataTable value="#{test.data}" var="item" rowKey="#{item.id}" selectionMode="single" selection="#{test.current}">
      <p:ajax event="rowSelect" partialSubmit="true" process="@this" update="@form" />
      <p:column>#{item.id}</p:column>
      <p:column>#{test.current == null ? 'null' : test.current.id}</p:column>
      <p:column>#{item.text}</p:column>
    </p:dataTable>
    <p:commandButton value="Update" ajax="true" process="@this" update="@form"/>
    <p:commandButton value="New" ajax="true" process="@this" update="@form" actionListener="#{test.clear()}"/>
    <p:commandButton value="Clear" ajax="true" process="@this" update="@form" actionListener="#{test.setDummy()}"/>
  </h:form>

Example Bean

@Named
@ViewScoped
public class Test implements Serializable {
  private static final String src = "Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut";

  private List<TestObj> data = null;
  private TestObj current = null;
  private final Random rand = new Random();

  public void clear() {
    data = null;
  }
  public List<TestObj> getData() {
    return data == null ? newData() : data;
  }
  public TestObj getCurrent() {
    return current;
  }
  public void setCurrent(TestObj o) {
    current = o; 
  }
  private List<TestObj> newData() {
    current = null;
    data = new ArrayList<>();
    for(int i=0; i<10 ; i++) {
      int off = rand.nextInt(src.length()-20);
      data.add(new TestObj(i, src.substring(off, off+20)));
    }
    return data;  
  }
  public void setDummy() {
    current = new TestObj(-1, "dummy");
  }
  public class TestObj {
    private final int id;
    private final String text;
    public TestObj(int n, String t) { id=n; text = t; }
    public int getId() { return id; }
    public String getText() { return text; }
  }
}
