Re: [Rails-devel] Tracking Down Errors

The 'rails' stack trace lines in question were: at rails.game.MapHex.addHome(MapHex.java:963) at rails.game.MapManager.finishConfiguration(MapManager.java:153) at rails.game.Game.setup(Game.java:188) at rails.ui.swing.GameSetupWindow.startNewGame(GameSetupWindow.java:481) at rails.ui.swing.GameSetupWindow.actionPerformed(GameSetupWindow.java:237) and usually the error is pointed to by the first of such lines. I have committed a fix that adds a check of the home city number against the number of cities in the current hex/tile. An error now throws a ConfigurationException, which will be catched and cause a popup to display an appropriate message. It might be a good idea to scan all 'finishConfiguration()' methods for such inconsistent XML values, and perhaps the 'configureFromXML()' methods may also need a sharper look. This fix may serve as an example. Volunteers?
