Subject Problem with external javascript while parsing responce
Date Tue, 21 Oct 2003 17:16:46 GMT
Hello community!

I'm using jakarta-cactus-1.5-beta1 with httpunit-1.5.4 and experiencing 
the following problem while parsing HTML responce with external 
javascript:


There was 1 error:
1) 
testActionUserSyncPrefEdit(com.g2x.agility.web.UserSyncPrefActionHandlerTest)java.lang.NullPointerException

Responce HTML being parsed looks like:

<html>
<head>

<link rel="stylesheet" type="text/css" href="../jsp/css_dom.css">
<link rel="stylesheet" type="text/css" href="../jsp/css_dom_sync.css">

<style type="text/css">
        div.frm_subformSection {display: none}
</style>

<script language="JavaScript" src="../jsp/JSConstants.js"></script>
<script language="JavaScript" src="../jsp/js_lib.js"></script>
<script language="JavaScript" src="../jsp/validate.js"></script>
</head>

<body>

<form name="form0" action="../servlet/controller" method="post">
<!-- big form goes here -->
</form>

</body>
</html>



As you can see the exception occures in 
com.meterware.httpunit.ParsedHTML.getIncludedScript which tries to call 
method at WebWindow object which is not set (it is null).
Probably code in WebResponseObjectFactory.createHttpUnitWebResponse that 
calls WebResponce.newResponce
weach leads to creting WebResponce with WebClient _client field equal to 
null should be changed.

I had the same problem with jakarta-cactus-1.4.1 + httpunit-1.5.4

So the question is: is there any workaround for this?
Any help will be greately appreciated.

Aleksey.
