I had forgotten to put my datable (and so my commandbutton) in an form, so it was just the button that was not active ... arghh ! thank you for your answer though Actually I have tried something else that does not work : I would like to call functions returning strings at the loading of the page so that I can have dynamic content. For example I would have : Hello #{createAccount.testing('Test1')} !! how are you today ? do you know by any chance a way for doing that ?
