I've tried to investigate the source of the bug myself and found out that the
assign color field in the dialog of an calendar resource only gets highlighted
when the selection of a calendar has been changed because there is only a
connect between the Signal selectionChanged(QItemSelection,QItemSelection) of
the class QItemSelectionModel (lives in
mSelectionProxyModel->selectionModel()). This connection is created in the
setter function setCollectionSelectionProxyModel in
korganizer/akonadicollectionview.cpp. I tried to add another connect for the
signals "currentChanged" and "currentRowChanged" of the class
QItemSelectionModel but these Signals just don't get triggerd, when I change
the focus to a different calendar element. I checked it via cgdb...
I'm not so experienced in c++ and qt programming and really would like to
understand, why these signals are not called. Please help me :-) Here is the
code I added:

void AkonadiCollectionView::setCollectionSelectionProxyModel(
KCheckableProxyModel* m )                                                       
{                                                                               
  if ( mSelectionProxyModel == m )                                              
    return;                                                                     
  mSelectionProxyModel = m;                                                     
  if ( !mSelectionProxyModel )                                                  
    return;                                                                     
  mBaseModel->setSourceModel( mSelectionProxyModel );                           
  connect( mSelectionProxyModel->selectionModel(),
SIGNAL(selectionChanged(QItemSelection,QItemSelection)), this,
SLOT(selectionChanged()) );                                                     
  connect( mSelectionProxyModel->selectionModel(),
SIGNAL(currentRowChanged(QModelIndex,QModelIndex)), this,
SLOT(currentRowChanged()) );                                                    
  connect( mSelectionProxyModel->selectionModel(),
SIGNAL(currentChanged(QModelIndex,QModelIndex)), this, SLOT(selectionChanged())
);                                                                              
} 

void AkonadiCollectionView::selectionChanged()                                  
{                                                                               
  updateMenu();                                                                 
  updateView();                                                                 
}                                                                               

void AkonadiCollectionView::currentRowChanged()                                 
{                                                                               
  updateMenu();                                                                 
}                                                                               

void AkonadiCollectionView::currentChanged()                                    
{                                                                               
  updateMenu();
