Part of a conversation between Andrea Burattin and Boudewijn van Dongen in which Andrea asked:
I have the AuthoredType PLGProcessCollection that extends Vector<PLGProcess>. When I use it, the action tab matches also the second parameter of Declare miner, that is just a Vector.
This not strange behavior at all. You cannot use types with generics (i.e. <?>) as input for plugins. The reason for this is a limitation in Java that generics are only available at build time, not at runtime. ProM is simply unable to verify if the right generics are set, as this information is removed in class files.
