[Moose-dev] trees in Glamour

Hello, I am constructing a tree presentation with Glamour. Parents are modules in my tree and children are a module's functions. Here is the code: modulesIn: composite ^ composite tree title: 'All Modules'; showOnly: 50; display: [ :each | each allModules]; tags: [ :each | {each numberOfFunctions asString} ]; format: [ :each | each mooseName]; selectionAct: [:each | each selection inspect ] on: $i entitled: 'Inspect'; icon: #mooseIcon; children: [:each | each functions ]. Now, when I click on a child, glamour wants to executes the children and tags block on a function in the above code. Now since my functions do not understand the messages functions/numberOfFunctions, there is an error. My question: for constructing a glamour tree, should parents and children both understand the same API or am I missing something here? thanx Usman
