Hi @marinam,
What you can do is use code behind instead of the Behavior to show/hide sections.
When the page loads, you can show/hide the appropriate sections. And when the user submits, you can call a custom submitbutton event to show all desired sections. This way, whenever the system tries to generate the FORM_ARCHIVE file, you’ll see all sections that were hidden until the submit button got clicked.
You can use something like this to hide/show sections:
SECTION_ID.Visible = true;
Hope this helps.
Eddy.
