It would be great if you could post to the community what are these "little modifications" you've mentioned. 
Cheers, CM.
Cheers, CM.
sure, no problems. was just waiting to see if it interests someone at all… 
in the class UISearchCustomProperties in method generateControl(FacesContext, PropertyDefinition, String, String) i changed the component type in the else clause (~ line 402) i changed the component type from UISelectOne to UISelectMany. this only causes the app to crash when trying to go to advanced search screen since the ValueBinding for UISelectMany expects a list on any rendering attempt, while alfresco returns null on first rendering attempt. that required changing the field customProperties in class AdvancedSearchBean from HashMap to MyHashMap, a simple modified map which extends HashMap and returns an empty list instead of null when a request for the ValueBinding arrives.
now, i had to change the method search in the same bean in order to reflect the change. ~ line 876
in MyHashMap it's important to return LinkedList since JSF returns ArrayList and that is needed to differentiate between multiple selection types and other types which do not have ValueBinding. (getting LinkedList is equivalent to getting null as you can see in MyHashMap.)
finally, i had to add to SearchContext the method addListValueQuery and the appropriate field - Map<QName, ArrayList<String>> queryListValues
as similiar to queryAttributes for example.
the appropriate change in method buildQuery(int) is the addition of:
that's it. any further questions will be welcomed.
