Help! Checkbox on Table not working

Question

Help! I can't use a checkbox on a table to select rows.
I don't know what I'm doing wrong, I exactly followed very tutorial there is and all won't work. First I tried the one described by the Tutorial Divas, but couldn't get it to work.
I followed all the steps: add a HashSet to SessionBean1, then add a selected property of typ boolean and than set the selected property of the checkbox to the property in the SessionBean1 (selected). I changed the isSelected and setSelected methods, so they work with the HashSet.
But when I select some checkboxes in the table, the HashSet is still empty... When debugging I saw, that the SetSelected method is never called (althougt isSelected is called). Why is that? I couldn't find detailed information on the matter. I looked at the Table_Component_example, but there a bit different approche is used, with a TablePhaseListener.
I also read the part in Winston's blog, but that didn't really add anything and I tried the example described in the JSC Field Guide.
Finally some code:
public boolean isSelectedObservationPoint() {
        TableRowDataProvider rowData = (TableRowDataProvider) getBean("currentRow");
        if(rowData == null) return false;
            RowKey rowKey= rowData.getTableRow();
            if(selectedObservationPoints.contains(rowKey)) return true;
            else return false;
public void setSelectedObservationPoint(boolean selectedObservationPoint) {
        TableRowDataProvider rowData = (TableRowDataProvider) getBean("currentRow");
        RowKey rowKey= rowData.getTableRow();
        if(selectedObservationPoint){
            this.selectedObservationPoints.add(rowKey);
        else {
            this.selectedObservationPoints.remove(rowKey);
    }So the only thing is, that I changed the iterating over the Hashset to contains call (why wasn't that used in the first place?) But that can't really be the problem, as I doesn't do anything... SetSelected is never called (at least not when debugging).
Is there something I missed? Could this be a problem, that the table itself a rather complicated grid-layout?
Thanks

The JSP:

                                        </ui:tableColumn>
                                    </ui:tableRowGroup>
                                </ui:table>As far as I can see it is pretty much the same. Did I over look something?
