How to add SelectionListener to ADF table Programatically?

Question

Hi,
Iam creating ADF table programatically and trying to setSelectionListener(MethodExpression) to it. i am unable to pass parameter MethodExpression properly.
What i am trying to do is, need to get the values on row selection of table.
How to pass that method name in setRowSelection(MethodExpression) programatically.?
and Any one got sample code of performing row selection event programatically, i mean accessing the selected row in java class i.e., creation of table and adding listeners to it programatically.....
Thanks
Thoom

Thoom,
from the Docs:
public final void setRowSelection(java.lang.String rowSelection)so setRowSelection method take a string parameter, and when you look at the property inspector for 'RowSelection' in jdev (which setRowSelection is the peer) you see the possible values:
single, multiple, multipleNoSelectAll and none or their constant field values ROW_SELECTION_SINGLE, ROW_SELECTION_MULTIPLE, ROW_SELECTION_MULTIPLE_NO_SELECT_ALL, ROW_SELECTION_NONE. You use this property to let the framework know if you want row selection at all, single or multiple rows.
As you want to get the selected rows of a table you have to distinguish between singe and multiple selection, as they are handled in a different way. The default for single selection is to use the 'makeCurrent' selection listener from the bindings
#{bindings.YOUR_TREE_BINDING.collectionModel.makeCurrent}To Set this in code you need to generate an MethodExpression out of it
MethodExpression ex = JSFUtils.resloveMethod("#{bindings.EmployeesView1.collectionModel.makeCurrent}", Object.class, new Class[]
                            { SelectionEvent.class });
table.setSelectionListener(ex);
    public static MethodExpression resloveMethod(String expression, Class returnType,
                                                 Class[] argTypes)
        FacesContext facesContext = cesContext.getCurrentInstance();
        Application app = facesContext.getApplication();
        ExpressionFactory elFactory = app.getExpressionFactory();
        ELContext elContext = facesContext.getELContext();
        MethodExpression methodExpression =
            elFactory.createMethodExpression(elContext, expression, returnType, argTypes);
        return methodExpression;
    }Timo
