Eclipse Plugin: Content Assist

The Content Assist is showing a strange behavior. If you type the code bellow
(in a Scala project or in an Scala Class in a Java Project):

object Test01 extends Application {
val ls = List(1, 2, 3)

ls.for|
}

and (at the "cursor" | position) type Ctrl-Space, the code completion
writes:

ls.format(text, xs) (I was looking for
"foreach")

but if you type "ls.fo" and type Ctrl-Space, the code completion window
shows up with the correct options (including the desired "foreach"). If you
then type "r", the options are correctly reduced, but if at this point you
type Ctrl-Space to circle through other templates like SWT or JPA, the
default Scala template does not show the correct options anymore, listing
only "format".

Is this a bug? Should be reported?
