Form Wizard Pro Exception: Failed to load viewstate.

Hi Joe,

Upgraded to the latest MP and FWP. Seeing an exception following form submit:

2013-09-23 11:39:38,962 ERROR - en-US - useragent Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0; Touch)
System.Web.HttpException (0x80004005): Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Re: Form Wizard Pro Exception:

Hi,

That kind of error can only happen if something changed between the time the page originally loaded and when postback occurs. ie that error could be caused by loading the page in one browser window and then in another browser window changing the skin of the page. Now when the page posts back still using the old skin it would cause this error.

Other than that I know of no way to produce that error except by script bots that cause viewstate errors on purpose.

There is no known bug in the current version of Form Wizard Pro that I'm aware of, you have not provided any steps that produce the problem for me. It does not throw any errors on our demo site.

Best,

Joe

Re: Form Wizard Pro Exception: Failed to load viewstate.

Nothing unique about the steps ... with IE 10 opened the page containing the form, entered fields and submitted. Never switched browsers or skins. The form is a two column form with associated CSS and option to flatten pages as groups. For now back on the previous version but later will try loading the form on the demo site.

Re: Form Wizard Pro Exception:

I just tried Form Wizard on the demo site with IE 10 and no errors. I even made sure the form had a choose from a list question since that is the only thing that changed, I added one to the Form Wizard Survey demo and it works fine.

Re: Form Wizard Pro Exception:

Hi Joe,

I just reproduced the exception on the demo site.

Look for the FW Test page under More.

Re: Form Wizard Pro Exception:

Hi,

I was able to reproduce the problem using your form definition. I've just uploaded a patched version of Form Wizard Pro 2.6.1.2 that should fix this problem. Can you download it again and confirm the fix? The only file in the package that changed since the initial release of 2.6.1.2 is the sts.FormWizard.Web.UI.dll

Thanks,

Joe

Re: Form Wizard Pro Exception: Failed to load viewstate.

Hi Joe,

Sorry spoke too soon ... the exception is resolved however the behavior of the choose from a list type has changed such that the first item in the list is always selected rather than displaying "Please select...". This causes unanswered questions to appear in notifications.

Dropping back to the previous version restores the usual behavior.

Re: Form Wizard Pro Exception:

Hi Bill,

Sorry I missed that, this one is now also patched in the Form Wizard Pro 2.6.1.2 download. Again the only changed file in the package is sts.FormWizard.Web.UI.dll

Thanks,

Joe
