Guys, I found an error (at least in my install) where after editing a comment I got an "underfined" error.
I traced down the error to client.js script, near line 280. It appear that at least for IE7, the responseText attribute gets undefined when removing a post, so I added a previous check for it before testing its value.
Here's the fix
if (JOSC_ajaxReady()) { // @willy - fixed on cases were responseText is undefined (perhaps a more deep fix avoids this...
if ((JOSC_http.responseText) && (JOSC_http.responseText != ''))
alert(JOSC_http.responseText);
else
JOSC_removePost(document.getElementById('post' + id));
}
Perhaps a better fix is possible or even it's just my particular installation.
Hope this helps, Willie.
