Hum it works for me in the latest Pharo (40152). Perhaps it is related to the last but one build that crashed because Smalltalkhub was not responding. Please retry in the last Pharo image. 2014-08-04 14:45 GMT+02:00 Esteban Lorenzano <estebanlm@gmail.com>:

it does not appear in the inspector options, when inspecting an Array or an OrderedCollection. any clue?
