Strange behavior in Default.aspx

After some research and experimentation, I will answer my own question.

Along with upgrading the application to use the newest WebCombo version 6, I am upgrading to using .Net 4.5 and on IIS 7.5. After some research, I came across this article on asp.net. After reading through, I ended up having to use the second workaround which is:

If the problematic HTTP modules have to run for all requests (for static files, for extensionless URLs that resolve to the DefaultDocumentModule object, for managed requests, etc.), modify the affected .aspx pages by explicitly setting the Action property of the page’s System.Web.UI.HtmlControls.HtmlForm control to a non-empty string. For example, if the default document is Default.aspx, modify the page's code to explicitly set the HtmlForm control’s Action property to "Default.aspx".

Therefore, on my default page, I changed my form tag to include action="Default.aspx" and this appears to have solved the script error. The WebCombo now work whether or not Default.aspx is part of the URL request.

I am in the process of upgrading a fairly large application that uses WebCombo 2 to use WebCombo 6. I have a page in my application that contains a WebCombo. It is the Default.aspx page in a sub-folder of the application. I'm seeing a strange behavior. When I explicitly call the page, as in http://localhost/MyApp/MyFolder/Default.aspx, the WebCombo works fine. However, when I call the page by http://localhost/MyApp/MyFolder and allow IIS to use the default page of Default.aspx, I get a script error. If I break in the script debugger, the highlighted line is:

ve4a23.open("POST",v1d568,this.Asynchronous);

The value of ve4a23 is an object with methods: abort, getAllResponseHeaders, getResponseHeader, open, send, setRequestHeader. The value of vld568 is "" and this.Asynchronous is true.

I am running this in IE8 and have tried setting ISNet.WebUI.WebCombo.v6_0_7200.RenderingMode to "Quirks" and "XHTML" without success. When I run the same page in Chrome, I do not have this issue.

I have been unable to reproduce this in a simpler application.
