> I am inserting a script 'X.js' dependent on a condition (c:if). The default
> case is to include it. If I change the underlying value within an action so
> that the condition evaluates to false, the script is still included. Also
> after any other following action.
> Using F5 in Firefox the page is now rendered without the script.
> The script 'X.js' was added to the view root and is never 'forgot' or
> removed. It is the same if the script is included in a composite component.
> In that case I even observed that the order of the scripts changes and the
> script 'X.js' is included before other basic scripts like jQuery on which
> 'X.js' depends.

> If I change 'HtmlOutputScriptHandler' to set the script transient, it works
