BUG-Data Node viewer not working properly

[FlorianJacta]

Description This issue is hard to explain and replicate with other code, so I will provide a link to an application with a code. The application is about predicting sales. You can create a scenario. You have to give a CSV as input for the scenario; you can find a CSV here: data/holiday_low.csv.

I will list the issues I see:

• My holiday Data Node is not updated correctly, even in the develop version. Sometimes, I see that this is tabular data, but the content loads forever.
• My result Data Node after the completion of the scenario will not be updated even if, in the code, I correctly refresh the results.

How to reproduce

• Clone this repo and open the src folder.
• Run the app.
• Go to the Predictions page.
• Create a scenario.
• Upload the CSV file (found in data/holiday_low.csv)

Expected behavior Everything should be refreshed correctly even without explicitly refreshing it.

Runtime environment Please specify relevant indications.

• Taipy: develop

Acceptance Criteria

• [ ] Ensure new code is unit tested, and check code coverage is at least 90%
• [ ] Create related issue in taipy-doc for documentation and Release Notes if relevant

I created some code to replicate the first issue. The first Data Node viewer doesn't show the data. I wasn't able to replicate the "Invalid time value" and the problems on Data Node selection.

    return datetime, date, int_var, string_var

Is this still an issue @FlorianJacta ?

[FlorianJacta]

Works great! I cannot replicate the issue
