'undefined' is null or not an object


I got this error when testing the OpenDialogButton in IE7 when I try to close the dialog using the IE7 tab close button.
The sample in also produces the same error in IE7, open a "poorly" designed dialog box, then close the tab/window via its close button.

I found the source of the error in the MetaBuilders_DialogWindow_DoDialogPostBack function in the DialogWindowBaseScript.js file. It was not checking if the result was undefined. See below.

broken code:
if ( result == null) {
result = info.DefaultValue;

fixed code:
if ( result == null || result == undefined) {
result = info.DefaultValue;

I also attached an updated DialogWindowBaseScript.js if you want to get the source and rebuild the project with this change.

Thanks ewsachse! That fixed the DialogWindow and DialogInputBox in one fell swoop!
