Hello (again),
In my particle-based game, I want it to be able to make an XML file using proXML with data from two (there may be more later) arrays. I'm using SpringGUI for the GUI, with this code:

void handleEvent(String[] parameters)
{
(lots of other stuff)
 if(parameters[1] == "save_filename_textarea" && parameters[2] == "returnPressed")
 {
   filename = parameters[3];    
   xmlEvent(new XMLElement("game"));
 }
}

I get an InvocationTargetException (no line numbers or the "at ..." lines that errors usually have) when  trying to save it, which seems to be caused by the xmlEvent() line. I don't know what an InvocationTargetException is, since the only type of programming I've done before is PHP...
