Description Stephan Eberle CLA 2011-04-08 22:13:40 EDT 
= Problem description =
The purpose of ExtendedItemPropertyDescriptor#getValue() is to avoid that default values for unsettable attributes are displayed unless they have been explicitly set. Currently this is done for single and many-valued attributes. However, the default value display suppression is not necessary for many-valued attributes and causes NullPointerExceptions when attempting to edit such attributes in EMF.Edit based property sheets.

= Resolution approach =
Suppress default value display for unsettable single-valued attributes only.
