[Pharo-users] Another question about Spec

Hey, I use drag and drop between two lists in a project and I read this tutorial [1] to learn how to do it. My question is: Is there a way to have another object than a String as passengers in #acceptDropBlock: (I get passengers the same way as in the tutorial i.e sending #passenger to transfer object) like the objects really in the list? Because if I use #displayBlock: it became difficult to be sure I retrieve the object I dropped in the source list... Thanks in advance, Julien [1]: http://spec.st/docs/drag_n_drop/
