Problems with Designelements in mailfiles using SCT

Hi !I still a have a issue with the using of SCT and changing design elements in the template for the SCT Mailfiles.

Every time when there is small change in the Template for the mailfiles I will get problems with the signatures of the designelements which will result in ECL Security Alerts and the users are blocked in working.

Here is my enviroment:

Normal mailtemplate based on StdR6 Mail (6.5.3) → Maintemplate

Created a copy from the maintemplate and activated the SCT option (this template will now inherit the design from the maintemplate)

Converted all mailfiles with the SCT template → lo convert, lo design, lo compact

Everything fine ! Clustered enviroment (almost 2 mailserver), 30 servers totally.

When I change now a form or folder (for example inbox) and refresh the design

(maintemplate → sct template → mailfiles) I will get Execution Security Alerts when creating a new schedule or new todo (if changed), because document has been corrupted or modified since signed! (data) (will be shown in the status bar).

What is wrong ? Or what must I do to prevent this problem ?

The only solution is then to convert the mailfiles with a template without these corrupt elements.

Only design task will not fix the problem. A convert with the same template or a copy of the template also not.

Thanks
