Can someone help me? Don't want to release an App with a patch that I don't understand?
Thanks to those who can help me

It is not obvious as to where your problem lies...Perhaps provide a simplified example aia project?

Hello TIMAI2
Thank you for your answer. TestShowChooseDialog.aia is the simplified sample project. It also creates a log file (Debug.txt). Can you try my App and help me understand where I'm wrong?
Best regards

You need to upload or link your example project...

6

You need to enable the disabled block,which you mentioned in you post, else it will keep updating the same key for the dictionary
lexical_variable_get (5)

and that will result into duplication of results.

Now you can see there is no duplication of records.

Sorry I did not understand. The example is in the first message.

Sorry, I did not see that :wink:

Hi rnareshu,
thanks for your help. Even if I did not understand your explanation, you tell me that it is necessary and correct to clean "OrderLavoro" because the new values ​​are not overwritten, but append. Is that so?

To debug your app sometimes, users might request you to provide a project. Gianmario, open your project, on the top bar, select Project > Export selected project (aia) to my computer, then upload the downloaded AIA file here.

The OP' uploaded test aia in the beggining of #post1

I did all possible debug with very reduced number of blocks but sorry I couldn't locate the issue, more probally it seems to be dictionary issue {not sure} or may be some memory or refrence issue, don't know.

Even with these number of blocks when I click on following block it is updating the existing added items in dictionary.

Thanks rnareshu,
also for me it is a memory allocation problem.
We await the opinion of an expert.
