Online Interactive Form - Blocks Web Page

Question

SAP BASIS LEVEL: 15
(ADS)  connection test: 800.20080218110307.448744
Adobe Reader 8.1.2
last sap note implemented: 1092088 (to enable pdf editing)
test: FP_TEST_IA_01 - works properly!
SCENARIO:
ABAP web dynpro with UIelement for interactive form display and editing.
1- 1st Web dynpro view with IForm element, (enable option = True) so user can edit the IForm.
2- Data node for Binding has 0-n cardinality (so in IForm a dynamic table will be generated)
3-  2nd Web Dynpro View, UI FileUpload for Iform Upload.
PROBLEMS:
1 - On Upload view, I tried the the Auto-Binding combining FileUpload and UI IForm element (as sap note)  but dosen't work. For now I solved the problem the old way, converted the xml from bin to string, parsed the XML and then did backward-data-binding.
2- On PDF display view, the pdf is displayed correctly and it's editable, but any other actions user tries to do on the web page don't work.
  2.1 I have a (navigate back) button on the web dynpro, but  once the pdf is displyed, no interaction with the web page is possible.
  2.2 Context binding between WD and IF, not working properly, seems to add empty elements in the data node. (if in WD context i have N elements - IN IF Data Herarchy I have N + M elements, M = empty elements)
NOTE: when enable option = FALSE, everything works ok, but Form is no more editable.
Help needed....

One more thing:
If I put the view that contains the Iform in a popup window, I get this error when I try to close the popup, or any action on the popup window:
Short text
    The ASSERT condition was violated.
What happened?
    In the running application program, the ASSERT statement recog
    situation that should not have occurred.
    The runtime error was triggered for one of these reasons:
    - For the checkpoint group specified with the ASSERT statement
      activation mode is set to "abort".
    - Via a system variant, the activation mode is globally set to
      for checkpoint groups in this system.
    - The activation mode is set to "abort" on program level.
    - The ASSERT statement is not assigned to any checkpoint group
