When using setError, setErrorByName or setRebuild methods, wether it be in validateForm or submitForm, it breaks my form by giving me a Allowed memory size of XXX bytes exhausted error when I submit the form.
Problem is, I don't see anything in the logs except thousands of "404" errors, as if I've something that trigger an infinite loop.
In the example, I have both setErrorByName and setRebuild, but it happens even with only one of them.
Can you think of anything that can trigger this error ?
