Reason: Partial fix only
The original js alert box which said "error" does not appear. Using Firefox 3.5.5 each of the widgets now appear to work correctly. (they didn't work originally). However, when using Internet Explorer 8 (on win vista), each of the widgets still display an error alert box on load, but the message is different...
"Object doesn't support this property or method"
How to reproduce...
(1) Navigate to http://localhost:8080/wookie
(2) Click "instantiate a widget"
(3) Use the default form data, click submit
(4) Copy/paste the url found between the <url></url> tags into another browser window
(5) Js error message appears
(Note: in firefox 3.5.5 the error does not appear at all)
This happens for chat, forum, vote, natter & weather. (Note: After the message appears, the widgets appear to work okay in IE, except the weather widget)
A clue might be in the local dwr adapter "wookie-wrapper.js" line 56 char 13 - as the weather widget falls over completely, pointing to this section of code. My guess is that IE is being fussy about some syntax here.
Not sure if we should treat this as a new issue or not, but the fix is only partial, so I have rejected it.
