>Thing is I've been trying to do a webapp with pharo and seaside and I've been using scritaculous updater and ajax to display several components in the same page without reloading it all. To put some context on the subject, it's a form to send commands to a subsystem on a satellite simulator. You choose a subsystem from a drop down menu, then the other drop down menu updates it's contents with the commands understandable by that specific subsystem. Up until here, everything's peachy. Thing is some commands require parameters and for that I thought why not make several (several = number of parameters the command takes) text input boxes appear when the user selects the command? So I tried that, but it doesn't seem to be working.
