QUESTION
I have to admit, it the most strange bug that i saw in TypeScript-JavaScript (I got Model class in TypeScript and ReactJS Component in JS...) . I have a list of Promo Object, inside this one a property "_listCompte" which is a list of Compte Object.
The list of Promo is created by retrieving data from database, all works at this point
After that i got a forEach on listPromo and it works, but when i try to iterate with forEach on a listCompte it's looks like is empty.
ReactJS Component :
...ANSWER
Answered 2019-Nov-23 at 02:43This looks like an async issue. You are retrieving the compteRef
s asynchronously, but you are not waiting until they are retrieved before calling setState()
in componentDidMount
, and you are not calling setState()
after they are finally retrieved.
Please try this. This should properly wait until all async requests have finished before calling setState()

Install giferror
You can use giferror like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
