3. Selection gives wrong key to backing bean
sorry but it works for me If I'm just adding dataScroller to our 3.3.3.Final demo:
public class ExtendedTableBean {
private String sortMode = "single";
private String selectionMode = "multi";
private Object tableState;
private Selection selection = new SimpleSelection();
private List<Capital> capitals = new ArrayList<Capital>();
private ExtendedTableDataModel<Capital> dataModel;
private List<Capital> selectedCapitals = new ArrayList<Capital>();
public String getSortMode() {
return sortMode;
}
public void setSortMode(String sortMode) {
this.sortMode = sortMode;
}
public String getSelectionMode() {
return selectionMode;
}
public void setSelectionMode(String selectionMode) {
this.selectionMode = selectionMode;
}
public ExtendedTableBean() {
}
public void takeSelection() {
selectedCapitals.clear();
Iterator<Object> iterator = getSelection().getKeys();
while (iterator.hasNext()) {
Object key = iterator.next();
getCapitalsDataModel().setRowKey(key);
selectedCapitals.add(getCapitalsDataModel().getRowData());
}
}
public ExtendedTableDataModel<Capital> getCapitalsDataModel() {
if (dataModel == null) {
dataModel = new ExtendedTableDataModel<Capital>(new DataProvider<Capital>() {
private static final long serialVersionUID = 5054087821033164847L;
public Capital getItemByKey(Object key) {
for (Capital c : capitals) {
if (key.equals(getKey(c))) {
return c;
}
}
return null;
}
public List<Capital> getItemsByRange(int firstRow, int endRow) {
return capitals.subList(firstRow, endRow);
}
public Object getKey(Capital item) {
return item.getName();
}
public int getRowCount() {
return capitals.size();
}
});
}
return dataModel;
}

4. Selection gives wrong key to backing bean
The only difference I see is that your data scroller is in the footer of the table, while mine uses the "for" attribute. Not sure if that would make a difference.
Anyway, since posting, I have gone a different route. I am manually setting the selected row by passing the key of the selected row to a javascript function that sets it on the backing bean. I am then waiting for this operation to complete before allowing the user to take action that would require the selection to be set on the backing bean.
