Hi,

I'm new to blackberry development, and also to Java, so fun here... lol

Anyway, im trying to make a basic data entry page for now, i've not got as far as posting/saving the data yet, as i cant even get it to display on the simulator screen due to the following error(s)

--
'Uncaught exception thrown' displays as the JDE window Title, a load of:
'source code is not available'

Are repetivly displayed line after line in a 'NoSuchFile.Java' window within the JDE...

Also in the debug window, this message is shown:
'CodeStore.DependencyList.buildModuleDependencyLis t() took 10 - [16]'

And eventually, if i step though enough 'source code is not available' errors, then the following error is displayed on the simulators screen:

Uncaught Exception: java.lang.NullPointerException

Please see my code below, perhaps there is something very obvious wrong with it...??

At first glance I don't see where you assign values to clientNameText or ageValue (BTW your comment style in your declaration section makes it very difficult to read, for me anyway) before you add() them to the screen. This could be the cause of the NullPointerException.

The reason the JDE/Debugger behave the way you describe is that the exception is thrown in the MainScreen (or some super class) for which you don't have debugging data. Since the exception is not caught in your app, the only other option for the JDE is to let the Java environment catch it by terminating your app, which wouldn't help you debug.

When you see that happen, somewhere in the JDE there should be a method call history. In the list of Calling Methods should be one of yours. If you select it the source screen will show you the file/line being executed when the exception was thrown.

I think thaht hrbuckley is right.

Sometimes I have this kind of error and it allways when I try to add something null to the screen.

Check each variable you have

Ivanov · 07-16-2008, 02:58 AM

The Exception should be thrown at

add(clientNameText);

as you are adding null to the screen as goulmass and hrbuckley mentioned.
you have first to create instances of all your fields you want to add to the screen before adding them

Hi,

Thanks everyone, double checked everything as suggested and seemed to get it working...

Main problem is i have no idea about java or the JDE atm, so it's very much a learning experience, lol.

Thanks for all your help though, now i just need to figure out how to get everything else to work that i want it to do, lol, but I need to walk before i can run right, ha ha :D

Anyhow, this is the updated code which now works, and thanks again.
