Thank you for your feedback Stephan.

I'll change asap the patch to take into account:
- ukdapi/type_reference/udkapi.idl (I had just changed 
offapi/type_reference/offapi.idl)
- commit message with [API CHANGE]

(and once the patch is accepted of course and only in this case :-), search
the release notes to update them)

For previous discussion about all this, see
http://nabble.documentfoundation.org/Multiselection-needs-work-td4153207.html#a4154535

To sum up:
GetFiles (from XFilePicker.idl) was implemented in several ways according
env (gtk, kde, aqua...) for multiple selection part
Some implementation truncate he selection to 1 file, others put the path for
first element and add the different filenames

GetSelectedFiles (from XFilePicker2.idl) is, a priori (it should be
checked), well implemented for every env, it returns only the n selected
files with their full path.

So the goal is to migrate from GetFiles  to GetSelectedFiles 

I made some changes (search "getFiles" in git history):
1) Describe and make GetFiles   deprecate
2) Began to change GetFiles for some envs to truncate to 1 file (so all the
implementations of GetFiles do the same)

It's only the beginning since, after these 2 points, every component using
"GetFiles" should be migrated to "GetSelectedFiles" (I'm not even sure that
these components could manage multiselection once they would retrieve a full
array of filenameswithpath)

Don't hesitate to put your remarks since there certainly must be some issues
I didn't think.

Julien
