[incquery-dev] eclipsecon example

[Tamas Szabo <tamas.szabo@xxxxxxxxx>]

Hi all

I have some notes regarding the current version of the example:
- the Writer's name derived feature is not working with the eval expression
- Xcore's original derived feature for the same expression works and 
also automatically updates the value both in the tree editor and in the 
property sheet
- I do not really understand the keep cache logic behind the Single and 
MultiValueQueryBasedFeature classes.

Regards,
Tamas
