Off-by-one error in input length for TextTParameter<n> #242

Closed EricDuminil closed 2 years ago

Currently,

the input HTML for TextTParameter<n> is allowed to have n characters. If n characters are typed, the parameter isn't saved, because the total length will be n+1 with the terminating NULL character.

If n-1 characters or less are typed, the parameter is saved correctly.
