Wt

Hello!

I'm currently evaluating Wt; and I'm quite impressed by how easy and Qt-like it works. But I've now hit a wall and need some help. When I update the model underlying a TreeView, the old text of the WStandardItem does not get replaced but the new text is appended. The following is an example of what I do; when pressing the save button, I'd expect that the selected item's text is replaced with "5", but what I get instead is "15" or "25" respectively.

class TestApp : public WApplication {
public:
  TestApp( const WEnvironment& env ) :
    WApplication( env ) {

    WPushButton* button = new WPushButton( "save", root() );
    button->clicked().connect( SLOT( this, TestApp::save ) );

    model_ = new Wt::WStandardItemModel( root() );

    model_->appendRow( new WStandardItem( "1" ) );
    model_->appendRow( new WStandardItem( "2" ) );

    treeView_ = new WTreeView( root() );
    treeView_->setModel( model_ );
    treeView_->setSelectionMode( SingleSelection );
  }

  void save() {
    WModelIndex i = *treeView_->selectedIndexes().begin();
    model_->itemFromIndex( i )->setText( WString( "5" ) );
  }

  WTreeView *treeView_;
  WStandardItemModel *model_;
};

Thanks in advance for any help!
