-------------------------------------
I think we might have already fixed this in the 2.1 series, can someone verify
whether this is already fixed.
> JavaScript errors due to hyphens in action names
> ------------------------------------------------
>
> Key: WW-2750
> URL: https://issues.apache.org/struts/browse/WW-2750
> Project: Struts 2
> Issue Type: Improvement
> Affects Versions: 2.0.11.2
> Reporter: Miguel Diaz
> Priority: Minor
> Fix For: Future
>
>
> Action names may include some characters (such as hyphens) that cannot be
> part of a JavaScript variable name.
> In form related tags, the action name is used as a part of the generated HTML
> tag name and/or id.
> This causes invalid JavaScript when a HTML tag name/id is used as part of a
> JavaScript variable, such as in <s:doubleselect> generated JavaScript (an, I
> think, also in JavaScript validation code, but I'm not sure).
> A simple fix would be replacing all prohibited characters with underscores in
> the generated HTML tags names and ids.
