Set property to empty - SAP CRM WebUI

Question

I am new to SAP, and am encountering an issue I am not sure how to resolve.

I am setting a property to '' (empty), but it is not being displayed as such.

There is existing logic that sets specific fields to 'Display Only' when a checkbox is checked. I am working to extend this to clear any data that is within those fields. Due to how the original logic was implemented, this change is being handled in the "Get_..." method (may be moved to an event handler once I get it working).

Currently, the logic sets the property to be empty (I have confirmed this with debug); however, the webpage keeps the original value. A shortened outline of the code is below (all try catches, etc. removed to keep it short and simple):

DATA: current     TYPE REF TO if_bol_bo_property_access.
DATA: dref        TYPE REF TO data.

current = collection_wrapper->get_current( ).
dref = current->get_property( 'FIRSTNAME' ).


* If condition
DATA: copy          TYPE REF TO data.

FIELD-SYMBOLS:
      <nval> TYPE ANY,
      <oval> TYPE ANY.

ASSIGN dref->* TO <oval>.
CREATE DATA copy LIKE <oval>.

CLEAR value.

TRY.
    CALL METHOD if_bsp_model_util~convert_from_string
    EXPORTING
         data_ref       = copy
         value          = value
         attribute_path = attribute_path.
    CATCH cx_sy_conversion_error.
        RAISE EXCEPTION TYPE cx_bsp_conv_failed
        EXPORTING
              name = 'FIRSTNAME'.
ENDTRY.

current->set_property_as_string(
          iv_attr_name = 'FIRSTNAME' 
          iv_value     = value ).

value = current->get_property_text( 'FIRSTNAME' ). "Check empty ''

Most of this was pulled from the 'Set_...' method. Any help would be appreciated.

This issue is due to the CRM browser autosaving before the case is complete. This causes the values to be rendered as though they are cached.

Note 2104051 resolves this.
