NullPointerException when handling javascript

[Alin Dosoniu <ad...@hotmail.com>]

Hi,

I'm trying to test the myfaces examples with httpunit.
I intalled the myfaces-examples.war in Tomcat and trying to access from httpunit the first page of the application.
Myfaces-examples has a tag (<x:panelNavigation>) that generates a code like this:

<tr><td class="navitem">
<span class="navitem">
    <a href="#" onclick="clear_linkDummyForm();document.forms['linkDummyForm'].elements['autoScroll'].value=getScrolling();document.forms['linkDummyForm'].elements['linkDummyForm:_link_hidden_'].value='menu:nav_1';document.forms['linkDummyForm'].submit();return false;" id="menu:nav_1" class="navitem">Home</a></span></td></tr>

HttpUnit is throwing an NullPointerException when trying to handle a javascript script ("clear_linkDummyForm") from first page.

I attach the error that I get from httpunit:
java.lang.NullPointerException

Can this problem be solved in httpunit?

Thanks,
