I've written a Blackberry appliation with the Blackberry JDE, running on a 9000 simulator. I tested it a week or so ago and loaded it on a Blackberry 9000 phone, and everything worked just fine. Sometime between then and now, though, something went wrong.
My code does the whole moving arrow "loading things from the internet" or whatever thing, but no screens pop up. My original screen, which is just a MainScreen with a RichTextField doesn't load at all. This screen, at least, has most likely not changed in the passing week, so if something broke, it would be in one of the later screens/lines of code that it shouldn't even be getting to yet!
Is it possible that my .jad or .cod file are corrupted somehow? I noticed that when I first put code on my machine, I just stuck in the .cod file that Eclipse provided me. Then, last week, the .cod file it gave me didn't work, because it was ACTUALLY a zip file with a two .cod files inside of it. Using the .cod file with the same name as the .cod file they were in succesfully loaded my app. I did the same this time, and I don't get invalid cod file errors or anything, but the app is still as broken.
Is there some direction I should be looking? Is the issue likely to be in my code, the cod file, the phone, or somewhere completely else?

Edit: I've narrowed it down to the problem only occuring if I attempt to load a particular screen. My problem is that this screen is nearly identical to another screen that IS working just fine on the actual device. Both screens are generated from the same method (which makes a webservice call and gets XML back and parses it to populate the fields of the screen). The only difference is that the screen that is breaking is going to a different URL. This URL DOES work (both from a browser and from the simulated device), so I"m at a loss. The application doesn't seem to crash, (it's still running in the background), it just doesn't attempt to display anymore.
Edit:
Okay, I'm seeing some tunneling errors immediately after I load my app, (but before I execute any of my networking code). When i do execute my networking code, it works just fine, unless it happens to be for my "Rental" section. I commented out all calls to that, and made my menu item for Rentals simply make a print statement. The code behaves identically (it freezes, or displays a white screen after selecting the button). All other menu items work (including those that call threads or network methods). And the rentals menu sucessfully executes in the simulator.
private MenuItem _rentals = new MenuItem("My Rentals", 110,
10) {
public void run() {
//if the last thing I did was a rental
//just show the screen
//else, reload rentals
System.out.println("Rentals was selected");
displayError("Rentals was pressed");
// if(rental){
// System.out.println("It's a rental!");
// popScreen(getActiveScreen());
// pushScreen(_offeringsScreen);
// }else{
// System.out.println("Getting Rentals from scratch");
// RentalsThread _rThread = new RentalsThread();
// _rThread.start();
// }
}};
I'm at a complete loss here: The device debugger doesn't seem to even register me selecting the menu item, and not a single line of code executes! It just freezes! I'll try putting back in my RentalsThread call in the start of my program (which was also freezing) just to see if I can tease apart the problem with the Rentals Thread (which makes the Rental Screen), and the problem with the Rentals menu item.
