Hi,
there is another DXL problem. My experiences from my previous post
forced me to make DXL-based design changes only from Note 7.0.x clients. I am not happy, because our clients rarely have Notes 7. However, it still seemed to be feasible, but another problem:
All design elements modified by the DXL appear to be unsigned. Well, the last modified column in the view is filled, but I get new security warning for -no signature-.
I also tried Document.Sign on the design element - did not help.
Did anybody see this before? So many problems with DXL 
Thanks a lot!
Adam
