I somehow managed to persist an List to the datastore [declaring other ArrayList and then using it on setter, it somehow did not want to just store my list when passed to a setter]. But it does not work that way for removing items from the list.
I need a runnable block to run it in the transaction, what part should I put there and what action order should I have? Anyway, why does GAE use such an old DataNucleus version? It's rather weird...
