Views Field Collection relationship

Hello at all,
as the title says I have some issues with views and field collection. I want to build a block to show some titles of nodes from a content type which have the same terms from items of field collection.
So I built a view, filtered the content type with status published and added the relation CONTENT:XY where XY is the field collection.
Then I added a contextual filter with the field collection item from field XYZ with delta:all. And I didn't get a result. Then I thought that because XYZ is a referenced taxonomy field in the field collection I have to go a step further.
So second step: After the first relation from above I added a second relation to this with field collection item from field ....
The contextual filter I submit was then term from field XYZ. The UID from views suggested to chose the field collection but there is no result again...

So what do I miss here? Anybody has the same experience?
Another question in general for views:
Earlier in views 2 you could see the SQL statement in views. Where is this feature gone?

THX in advance
