[Pharo-users] Set programatically the selection for a fastTreeTable

Hi all, I'm trying to do what subject says. I tried something like that (in the example I'm trying to get Abort class selected) : | browser | browser := GLMTabulator new. browser row: #Example. browser transmit to: #Example; andShow: [ :a | a fastTreeTable column: 'Class Name' evaluated:[:clazz| clazz name]; children:[:clazz| clazz subclasses]; allExpanded; "this has no effect" strongSelection:Abort; "this has no effect" selection: Abort browser openOn: {Object} Could you please point me what I'm missing? TIA Arturo
