B4J Question [SOLVED] Maddening list bug

[JackKirk]

I've tried everything I can think of to fix this - last resort: post a question...

Here is the code:

Log(xxxx.Size)
Log(xxxx.IsInitialized)
        'For each ticket web request file...
        For wrk_ptr = 0 To xxxx.Size - 1                        '<<<<< this is line 631

wrk_ptr is an Int

Here is the log:

Waiting for debugger to connect...
Program started.
0
true
Error occurred on line: 631 (Main)
java.lang.RuntimeException: Object should first be initialized (List).

I have tried everything including cleaning the project, shutting down the PC etc but still it persists.

I know I'm doing something stupid but what...

I've check the example you've uploaded and I don't see any issue.

Erel, in the example I have provided at post #35, the error is reported as on line 34 but is actually on line 38

And is reported properly when the sleep statement is removed - in my real life case I had resumable subs in this "location".

I should add that I tried it with maps too - with the same problem.
