Render button ok but fields displayed as read-only(solved)

Question

Dear JHeadstart,
I'm trying to solve the next situation.
I'm Using a form with 'Same Page?' checked.
I'm rendering an add-button: when a row is not found I display the add button and when a row is found, the add button is not displayed.
This works well with the EL expression: #{bindings.<viewobject>InputDate.inputValue eq null} in the 'Insert allowed EL expression'. For if now row is found this field is null.
But when I press the add button I only get readonly fields where I'm hoping for inputfields to fill so I can insert a new row in the table.
In the jspx file I find, the EL expression I used, back for every field in the form.
The form is based on a VO based on 2 entity objects. One is always updateble (here I want to have the inputfields) and one is read-only.
I've also tried the EL: #{!((bindings.<viewobject>Iterator.currentRowIndexInRange!=-1 and bindings.<viewobject>Iterator.findMode!='true'))} which is used to render the value="#{nls['NO_ROWS_FOUND']}" in de jspx file.
but with the same results.
So what can I do to make those fields insertable?
Help will be appreciated!
regards,
Marcel.
After some more googling I found:

Section 7.9.3 got me on track.
In my create() the InputDate field was filled (sic).
When I used another field in the EL, it worked.

Finally I think I have found the problem.
In the View where I am printing the ADOBEFORM, it is needed this code under the method WDDOMODIFYVIEW.
method WDDOMODIFYVIEW .
  DATA: LV_INTERACTIVE_FORM   TYPE REF TO CL_WD_INTERACTIVE_FORM,
             LV_METHOD_HANDLER     TYPE REF TO IF_WD_IACTIVE_FORM_METHOD_HNDL.
  LV_INTERACTIVE_FORM ?= VIEW->GET_ELEMENT( 'INT_FORM' ). "   adobeform object in view
  IF LV_INTERACTIVE_FORM IS NOT INITIAL.
      LV_METHOD_HANDLER ?= LV_INTERACTIVE_FORM->_METHOD_HANDLER.
      LV_METHOD_HANDLER->SET_LEGACY_EDITING_ENABLED( ABAP_TRUE ).
      LV_METHOD_HANDLER->SET_HIDE_NAVIGATION_PANEL( ABAP_TRUE ).
      LV_METHOD_HANDLER->SET_DISABLE_PRINT_BUTTON( ABAP_TRUE ).
      WD_THIS->M_METHOD_HANDLER ?= LV_INTERACTIVE_FORM->_METHOD_HANDLER.
      WD_THIS->M_METHOD_HANDLER->SET_HIDE_TOOLBARS( ABAP_TRUE ).
    ENDIF.
endmethod.
