JQREQUIRE{"autocomplete"}, no such plugin autocomplete

Hi,

Foswiki Version 1.1.2

JQueryPlugin version is 4.0

and there is an error when I use "JQREQUIRE{"autocomplete"}" .

It is said "Error: no such plugin autocomplete"

"JQREQUIRE{"autocomplete"}" is rendered by "TwistyPlugin"

How to resolve this problem?

Thank you.
