since yesterday I get this fatal error: java.lang.RuntimeException: Object should first be initialized (B4XView).
when trying to access E1.TextArea1.Text, even after E1 is declared in Class_Globals and initialized under B4XPage_Created.
How can I fin out WHICH B4XView is missing or not initialized?

Thanks for advice, john m.

Thank you for Checking your code carefully.
That's exactly what I've been doing for the last two days, checking if everything is properly declared and initialized and setting various breakpoints.
And I still get this error when trying to access E1.TextArea1.text:
B4X: 
E1.TextArea1.Text
Error occurred on line: 387
java.lang.RuntimeException: Object should first be initialized (B4XView).

Baffeled by the word AbsObjectWrapper I may have to check the location of Java as in previous versions in other Subdirectories this never happened.

Best,

Sorry if that sounded rude, I didn't mean it that way. What I'm trying to tell you, is we can't know what's happening without seeing the code. The only thing we can see is that editText, in some point is not initialized, but we don't know why without seeing the code.

For new(er) members: How to post a question/issue

1. Please post the code AND the error message from the logs as TEXT within CODE TAGS. 2. Don't post images 3. Describe what the problem is (full sentences, not 3 words, not "my car doesn't work - guess what it is") 4. Use the search function FIRST (assume you're not the first person having that...

José: In the meantime I messed things up royally myself.
Klaus: The linenumber is in the B4J code.

Will restarted from an earlier autobackup that worked.

I was only trying to find out if there was an easy way to pinpoint the exact reason and location for the error instead of rudimentary statement like Object should first be initialized (B4XView) as this is not the first time this happens, particularly when creating copies for test purposes.

Nevertheless, thanks for all your help.

Maybe this is so obvious... (again) but compare the old version with the new one...

I found the solution in one of Klaus's booklets. I've already used it in another situation, but could get it to work if the target is in the B4XMainPage.
With the textarea in page2 I was not able to modify it from page3.
BUT I built a workaround and can now continue.
Thank you, john m.
