In context of
RF-13532, the attribute @resetValues was also added to components:
Seems like it was not an intention, because in the comment it is said:
I've added @resetValues to a4j:ajax and also to components extending BasicActionComponent (commandButton/Link, poll and jsFunction).
Similar unwanted list of influenced components was produced in
RF-11176 (and was fixed), when a new attribute was added to similar components:
Added onerror to AjaxProps, the attribute is now available to commandLink/Button, jsFunction and poll.
So this one looks like the same case.
