[Moose-dev] a small question in Glamour

Hello all, I construct a small browser in Glamour: | finder | finder := GLMFinder new. finder show: [:a | a tree title: 'Tree'; filterOn: [:text :each | text first = each]]. finder openOn: ($a to: $z). Now, I can enter a text and it allows me to filter the elements of the input list according to the input text. My question: Once I enter the query and my list get filtered, is there any way that I can return to my complete, unfiltered list? Hitting the return on empty search field does not execute the filter block. Is there a proper way to achieve the task of "un-filtering" or should I create some hack to allow the user to see the list of unfiltered elements? tx, Usman
