multi-restriction pattern throws UnsupportedOpEx

rule "same"
when
$m : ShGraphType( $x25No : x25No, $trans : trans )
GoType( x25No == $x25No || == ($x25No % 2000), trans Unable to render embedded object: File (= $trans ) #) not found.!!#
$e : ShType( x25No == $x25No )
$v : View( elemSet contains $m )
then

Field x25No is an int.

The marked pattern is not flagged in Eclipse, passes the compiler without an error, but crashes at runtime during fact insertion with:
