Apex Commandbutton does not fire actionmethod every time

Question

I have an apex page which relies heavily on rerendering certain parts of the page. The issue is that when I click on a commandbutton, normally it calls its action method, and rerenders a part of the page, however, it only works about half the time. On the other occasions the action method does not fire. (Something still happens, because it creates a debug log)

The confusing thing about it is that it happens seemingly randomly (e.g. It works, I reload the page, then it doesn't work, while nothing changed)

Unfortunately I don't have permission to post the code, but any idea would be appreciated.

Answer 1

It was caused by an actionsupport tag inside of a commandbutton which I think should be fine, but it wasn't. I deleted the actionsupport, edited the button itself to contain the rerender and action attributes, and now it works.
