After 'refresh' it works out.
But why do I get this error?

Thanks,

Hi,

Please give us the following info:

ECF 4.x release/build number
Full Source Code or Front End Source Code only?
Windows Server - OS + SP level
SQL Server - Version + SP level

Are you on the latest code base?  Here is a link to our Release History -- http://www.mediachase.com/ecf/releasenotes.aspx

There was a fix in our latest ECF 4.1.2 that addresses products not saving properly due to serialization not being set properly.

As a potential workaround, please read this thread --
http://www.mediachase.com/Community/forums/1/9824/ShowThread.aspx

Try re-saving your product(s) to see if this resolves your issue. 

Hope this helps.
