xform and ViewState Error
Are you perhaps using a load balanced solution where your users get sent to different servers on postback (and the server don't have matching machine keys)?

Another tips would be to check the actual xform xml definition and see that it hasn't changed from when you published it to when you view it.

The site usually runs in an load balanced environment, but lately only one node has been running, and we still get the same problem. The xform property doesn't have to be used, butt still the same error is thrown

This typicaly occurs if you have an editpanel plugin that adds controls in page load. For more info see:

(Seems only to be related to EPiServer CMS 5).

Hi,
We have an issue in our production environment regarding publish and edit of pages with a page type that contains a xform property. If we create a new page, saves it(save and publish for example), everything looks fine. But if we then hit edit again,the page fails with a viewstate error. If we then reload the edit UI again, we can edit and publsh and save and do whatever without ever getting this error again. IF the xform property is removed from the page type it works just fine. The strange thing is that this does not happen with the same source code in our development, test and stageing environment. Does anybody have a clue about what couses this?
