This thing is like a monster because:
You can't reason with it, understand it, or stop it from obstructing your submissions.
It doesn't tell you what it thinks is wrong, instead it will say something like 323.9 cannot be used as a numeric value.
I don't know where it is getting this value and why it is comparing it with a numeric type.
It covers my vision of the entire form I was submitting and gives me no option to return. When this monster gets upset it just stomps on everything.
I have validation turned off to try to prevent this thing from causing problems.
Yet it still remains.
