Hi,

Have you done this in the <i>wdDoModifyView()</i> method?

if (firstTime) {
      IWDTable table = (IWDTable) view.getElement("<table ID>");
      wdContext.currentContextElement().setCustomerTableSorter(
        new TableSorter(table, wdThis.wdGetSortCustomersAction(), null, new String[] { "CustomerTable_Name" }));
}

Because the TableSorter class calls the <i>init</i> method from its constructor and here's a section of the code from that method:

private void init(IWDTable table, IWDAction sortAction, Map comparators, String[] sortableColumns){
this.table = table;
if(sortableColumns == null){
sortableCols = null;
}else{
sortableCols = new HashMap();
for (int i = 0; i < sortableColumns.length; i++) {
sortableCols.put(sortableColumns<i>, sortableColumns<i>);
}
}

// sanity checks
if (sortAction == null)
throw new IllegalArgumentException("Sort action must be given");
if (table == null)
throw new IllegalArgumentException("Table must be given");
if (table.bindingOfDataSource() == null)
throw new IllegalArgumentException(
"Data source of table with id '" + table.getId() + "' must be bound");
//...

So in your case the table being passed is <i>null</i>. Also go through <a href="/people/bertram.ganz/blog/2006/03/07/enhanced-web-dynpro-java-tablesorter-for-sap-netweaver-04s blog.
