[TYPO3-mvc] Repository does not always insert values

[Wim]

I think you're right, it's the ajax request that causes the problem.
After a period of inactivity of half an hour, I refreshed the screen. No problem.
After a same period of inactivity, I selected an option to activate the ajax request. And yes, the problem was there again.

I use the extension pt_extbase for handling the ajax request.

But now, how to solve this problem. Any idea?
