TableSorter with WD in NW7.1

Question

Hello Community,
i'am testing with the table ui-component. now i want to realize sorting. for that i found here that one should use TableSorter.java as an utility-class for sorting.
doing so far works fine, but i have some additionals problems and maybee one of you could help me.
what is done so far:
with
  IWDTable table = (IWDTable) view.getElement("Table");
  wdContext.currentContextElement().setTableSorter(new TableSorter(table, wdThis.wdGetSortAction(),
                      null));     
  in the wdDoModifyView Method of my view controller i instantiate my TableSorter and bind it to a context-attribute.
and with:
wdContext.currentContextElement().getTableSorter().sort(wdEvent, wdContext.nodeReturn());
in my OnSort-Action  sorting takes place.
The problems:
1.)
doing above with the mentioned TableSorter-Class my table in unsorted at the beginning. the user has to click on a header to sort the data on that colum.
What i need is an initial sort, also showing the sort-icons correctly in the header
2.)
i have a detail view for the current-context-node. this is implemented by an additional view controller, which i connected via plugs and appropriate actions. When i return from a detail-view view-controller to the table-view-controller via plugOut, plugIn the data then is not correctly sorted.
Does anybody know how to achive this?
regards

Hello,
the method sortTable is not known in my TableSorter-Class, which is i discovered for nw04s in sdn. theres only one sort-method which expects an Event as addtional-parameter (as you can see in step 2 in my question).
my idea as a workaround was to call the sort-method after inistantiating the TableSorter-Class in wdModifyView. but i didn't know to create an event with the neccessary parameters for the event. but looking into the TableSort-Class and the Method sort i discovered that the method extracts the columnname and sortdirection as strings out of the event. so i created a copy of the Sort-Method in the TableSorter-Class with the same name but the parameters columname and sortdirection as string. Then it does the same then the original sort-method.
This works fine so far when calling this new method in wdModifyView after instantiating the TableSorter-Class. But unfortunatly, it does not show the sort-icons in the column header
Do you have any ideas how to show the icons from the first rendering of the view?
