Using methods other thang getters and listeners

Hi to All, After working for a while with T4, I now decided to start migrating to T5. But since the begining of that project I'm missing one of the T4 features that I really appreciate. Which the possibility to invoke in the HTML (now TML), some of the java methods other than the getters and listeners. Particulary, let say I have in my java page a List from which I want to retrieve one element whose index I know. In T4 I'd invoke myList.getItem(index). I've tried ${myList.getItem(index)}, b ut didn't work. I'd appreciate if someone can tell me what I miss or the way to do what I want. Thanks for your reply.
