gwt CheckBoxCell within CellList

Im trying to create a scrollPanel that holds a list of checkbox item. My main problem is constructing a CellList with CheckboxCell. Here is a snippet of whats causing the compile time error. 

CheckboxCell testCheckBox = new CheckboxCell();

CellList<String> cellList = new CellList<String>(testCheckBox);

Error Message: The constructor CellList(CheckboxCell) is undefined.

If this is the wrong constructor, what is the correct way?

You can try something like that. You are going to need some extra native code to handle the "check" event. 

public class StyleCell extends AbstractCell<Style> {
@Override
public void render(Context context, Style row, SafeHtmlBuilder sb) {
    if (row == null) {
        return;
    }
    sb.appendHtmlConstant("<INPUT TYPE=CHECKBOX NAME='property'>" + row.getProperty() + "</INPUT>");
}

}

StyleCell styleCell = new StyleCell();
CellList<Style> styleList = new CellList<Style>(styleCell);

Try changing the type of CellList to Boolean.

CheckboxCell testCheckBox = new CheckboxCell();
CellList<Boolean> cellList = new CellList<Boolean>(testCheckBox);

update:

More examples on various cells (this is combined checkbox + picture, but you might want to replace picture with text):

http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellTree

It's little trickier, but this showcase contains also sources so might want to dive into them.

PS: Lazier solution is not to use Cell Widgets and make own (extends Composite) combo/label and place it in say FlexTable :)
