Hi, I try to reproduce your test case (udig 1.1.1 / gnu linux), I comment my 
experience below:

this editor show "No feature selected" in the Property column. I try to 
different way to select features but I get the same feedback in the default 
feature editor.

1 - Because I cannot use the default feature editor, I create a new layer with 
"the_geom attribute"
2 - Select CQL in table view
3 - wrote DWITHIN( the_geom, POINT(6126665, 1836603), 50, km)
4- enter
Result: any feature selected

I try other spatial relation without success.

I did some additional tests
My layer has the following structure FID, the_geom (multilinestring), name  

test 1: FID like '%lin%'  result: nothing is selected
test 2: name like '%tres%' result: the featues are selected, so OK

Well, I think the cql query goes well if you select some field from the combo 
box. But in this combobox you cannot select FID and the_geom. 

cheers
