Werner Punz commented on MYFACES-2745:
--------------------------------------
Ok as it seems, the integrated ecmascript parser of html unit is less lenient
than the browsers I was testing against (and I was testing against all browsers
since ie6)
it seems to me that the error message is issued somewhere in the inheritance
part of the _Runtime.js but since the error is referenced against the compiled
file I cannot fully tell.
I have to make a test setup against the uncompiled scripts to check where the
htmlunit ecmascript parser fails.
But bear in mind this is an error which occurs in HTMLUnit only and not in any
browser.

> Key: MYFACES-2745
> URL: https://issues.apache.org/jira/browse/MYFACES-2745
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Affects Versions: 2.0.1
> Reporter: Michael Concini
>
> The javascript changes from 5/25 have caused a regression when using htmlunit
> against even the simplest JSF page as long as it loads the jsf.js script.
> The exception occurs simply executing getPage() on the webClient.
> WebClient webClient = new WebClient();
> HtmlPage page =
> webClient.getPage("http://localhost:8080/JSF20AJAXTag/DisabledFalse.jsf";);
> It can be recreated by a page with nothing but this form in the body:
> <h:form id="form1" prependId="false">
> <h:outputText id="out1" value="This is broken"/>
> <h:outputScript name="jsf.js" library="javax.faces" target="head" />
> </h:form>
> Attached is the exception trace from a run this morning which includes
> Werner's changes from MYFACES-2742 this morning so we are up to date in our
> sandbox.
