> Currently it's hard to hook in a myService.deleteMyObject(myObject) on a delete command without disturbing all the logic already in spring rich.
> The only way I see is by overriding deleteSelectedItems() with an almost exact implementation.
> It would be nice if it was like this in AbstractMasterForm:
>     /**
>      * Delete the detail item at the specified index.
>      * @param index Index of item to delete
>      */
>     protected void deleteSelectedItems() {
>         ListSelectionModel sm = getSelectionModel();
>         if( sm.isSelectionEmpty() ) {
>             return;
>         }
>         _detailForm.reset();
>         int min = sm.getMinSelectionIndex();
>         int max = sm.getMaxSelectionIndex();
>         // Loop backwards and delete each selected item in the interval
>         for( int index = max; index >= min; index-- ) {
>             if( sm.isSelectedIndex( index ) ) {
>                 deleteItem(getMasterEventList().getElementAt(index));
>                 getMasterEventList().remove( index );
>             }
>         }
>     }
>     /**
>      * Template method, hook for service calls.
>      * @param o the object to delete
>      */
>     protected void deleteItem(Object o) {
>     }
