Hi Ori,
sorry, I'm a real nerd ;-)
I had some textboxes with Unique-IDs. In the DOM I actually looked at the input-controls which do not have the CUID attribute. I now saw, that this attribute is applied to the DIV-tag which contains the actual controls (and which has a VWG_XXX ID).
There is only one problem, which is sitting right in front of my computer ;-)
Best regards & thanks for your help
Kristof
