OK I can reproduce now :) Well two things: you are doing it wrong ;) but you found a bug :D (or actually, multiple) the 'importFromMse' in the contextual menu imports the model from mse into the currently selected model. In this case, you are importing Merlin into the existing Merlin model, which duplicates everything. Perhaps the name of this action is not explicit enough? Anyway, the bug is elsewhere: - when computing FamixMethod>>numberOfLinesOfCode in Smalltalk, the name of the method is given to the calculator, which retrieves the compiledmethod given the name in the method dictionary - problem is that the method dictionary expects a symbol as a key - now a 'fresh' model from the Smalltalk importer does set a symbol for a FamixMethod name - but the MSE importer sets a string instead, hence the error when you try to compute number of lines of code on mse-imported famix method But why is there no error when I or Doru creates a moose model from the drop-down menu? - because the newly created model is not set as #isSmalltalk (because moosemodel attributes are not saved in the mse file, argh) - then numberOfLinesOfCode does not try to retrieve the compiledmethod and instead try to rely on sourceanchor -> and in the end it returns 0 (hence the white classes Doru noticed).
