SymbianError -1, KErrNotFound

[JOM]

Huh,

What could be wrong here, I just don't understand. Code (the very same file) works ok in S60 3.1 emulator with PyS60 1.4.5, but crashes in N82 (S60 3.1) running PyS60 1.4.5 PythonShell:

if DEBUG: print "111111"
#appuifw.app.body = appuifw.Listbox(entries)

# SymbianError -1, 'KErrNotFound'
# File "e:\\python\\flagicon48.py", line 237, in ?
# appuifw.app.body = appuifw.Listbox(entries)

# Unable to find the specified object

try:
    print appuifw
    print appuifw.app
    print appuifw.app.body
    global appuifw
    appuifw.app.body = appuifw.Listbox(entries)
except:
    import sys
    import traceback
    import appuifw
    cla, exc, trbk = sys.exc_info()
    excName = cla.__name__
    try:
        excArgs = exc.__dict__["args"]
    except KeyError:
        excArgs = "<no args>"
    excTb = traceback.format_tb(trbk, 5)
    errorString = repr(excName) + '-' + repr(excArgs) + '-' + repr(excTb) + '\n'
    print errorString

if DEBUG: print "222222"

Emulator trace:

As you can see, no problems whatsoever! But here's N82 trace:

111111

222222

So the line appuifw.app.body = appuifw.Listbox(entries) caused an Exception when running in N82! I just can't figure out what could be wrong... As far as I can tell appuifw does exist, entries (already made as global variable) exists, even appuifw.app.body should exist. What on earth is "not found" ?!?!? What else is there that could be missing? And why only in real device? Everything else works ok... Yep, just tested 10 other scripts, no problems!

Well, I'm writing this hoping that a) someone might be able to suggest ANYTHING and b) usually I figure out the problem/solution, when describing it to someone else.

Feeling lucky,

--jouni going to simplify the code even more rautalanka level

Huh2,

The magic works everytime, problem solved! Got fooled by trace output, which seemed to be ok. Turned out "entries" contained corrupted data, which just happened to look like real thing...

This weekend I'll release new sample code, which shows how to populate listbox with your own icons from your own MBM file. Yep, pretty boring. Not worth releasing at all. However the MBM contains 244 free-to-use and ready-to-use country flags, resolution 48x48 bits. Best of all, not drawn by me

Ok, there are some issues. Got to add link to icons' original website, flags share same mask which naturally doesn't fit all etc. Still pretty nice, I would say.

Cheers,

--jouni going to remove several hundreds of debug code and hoping everything would still work

Hm..I once was fooled by an empty element in the list. It irritates when such petty things cause delay.
