ADF Dynamic type of input elements

Question

Hi, I wonder if it is possible to create a form with dynamic input elements. In more details, imagine that I have a huge document repository. Documents are being inserted into that repository and they are separated by catalogs, profiles and properties. User must select catalog, then choose appropriate profile and then fill out all the properties of the document he is inserting. Some properties are dropdown menus, some date fields and others are plain text fields. My goal is to ease my GUI development with ADF, so can I somehow code oracle.adf.view.faces.model.CollectionModel to be used in ADF Table Component?
That is what I think:
In my jsf I will use some table:
<af:table var="p" value="#{myBean.requiredProperties}">
  <af:column>
    <af:outputText value="#{p.textLabel}"/>
  </af:column>
  <af:column>
    <????  value="#{p.inputElement}"/>
  </af:column>
</af:table>What may I use instead of ???? and how to code my method getInputElement() to return CoreInputText ,CoreSelectOneChoice or CoreSelectInputDate
Regards.

hi,
i had given one example it will help you
data: begin of itab_alv1 occurs 10,
          MAKTX like MAKT-MAKTX ,
          MATFI like MARA-MATFI ,
          MATNR like MARA-MATNR ,
          MFRPN like MARA-MFRPN ,
      END OF ITAB_ALV1.
type-pools: slis.
data: afield type slis_fieldcat_alv.
DATA: fieldcat type slis_t_fieldcat_alv.
clear afield.
afield-col_pos = 1 .
afield-fieldname = 'MAKTX'.
*afield-seltext = ''.
append afield to fieldcat.
afield-col_pos = 2 .
afield-fieldname = 'MATFI'.
*afield-seltext = ''.
append afield to fieldcat.
select * from mara.
   select * from makt where
         matnr = mara-matnr.
       itab_alv1-matnr = mara-matnr.
       itab_alv1-maktx = makt-maktx.
       append itab_alv1.
   endselect.
endselect.
CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
       IT_FIELDCAT = fieldcat
    Tables
       t_outtab = itab_alv1.
