Time formatet string in thtmlb dropdownlistbox after enter key or tab key

Question

Dear Collegues,
In our BSP-Application we use the thtmlb:dropdownlistbox. It's configured as you can see below in the code cutout:
DATA: wa_result type ZZPRBRS_PRSRG.
                  %>
                  <td>
                  <thtmlb:dropdownListBox id        = "DD_PREISREGEL"
                                          selection = "<%= DD_PREISREGEL %>"
                                          editable  = "TRUE" >
                    <%
  loop at APPLICATION->PRREG_TAB into wa_result.
                    %>
                    <thtmlb:ddlbItem key   = "<%= wa_result-PRSRG %>"
                                     value = "<%= wa_result-PRSRG %>" />
                    <%
  endloop.
  clear wa_result.
                    %>
                  </thtmlb:dropdownListBox>
As you can see the ddlb is set as editable.
So far so good.
But when we edit the entry in the box and leave the box with ENTER KEY or TAB KEY the controlle change the format of the entry to a kind of time format. Excamlpe:
We choose the entry GSVIES2 (one of the list entries) and we edit it to GSVIES22 the controll change it to 22:00. Longer entries will be changed to an entry like xx:xx:xx.
The wa_result-PRSRG for the entries is an char(12).
I found no notes about this issue.
Does anybody know this behave?
How can we avoid that changing after editing?
Kind regards
Thomas

Hi Thomas,
I was wondering, if you really want to have an editable DropDownlistbox, did they advise anything?
And, what do you think; should I go ahead and extent the THTMLB library with a ZDropDownlistbox which doesn't use the 'timepicker' javascript?
references to my questions:
BSP extensions: THTMLB
dropdownlistbox classes: CL_THTMLB_DROPDOWNLISTBOX, CLG_THTMLB_DROPDOWNLISTBOX
In the class: CL_THTMLB_DROPDOWNLISTBOX method IF_BSP_ELEMENT~DO_AT_END calls this JavaScript
*     Building a unique variable name (simply based on a new tag ID):
      lv_guid_str = me->generate_tag_id( ).
      CONCATENATE  'v_' lv_guid_str
             INTO  js_unlisted_timepicker_key.              "#EC NOTEXT
*     Building the script retrieving the KEY and saving it into that variable:
      CONCATENATE  `var ` js_unlisted_timepicker_key
                   ` = thtmlbConvertTimeToKey("`
                   js_new_selected_value
                   `"); `
             INTO  lv_script.
Kind regards,
Sander
