cl_wd_runtime_services=>attach_file_to_response

[PankajVPatil]

Hi,

I am using cl_wd_runtime_services=>attach_file_to_response method to download a tab delimited text file. Whenever a call to the method occurs, it runs into 'NULL' object reference error and points to the first statement within the method i.e. wdr_task=>client_window->client->attach_file_to_response.

The code snippet is as follows:

data: itstring TYPE string,
      itxstring TYPE xstring.
itstring = 'test run'.

  CALL FUNCTION 'SCMS_STRING_TO_XSTRING'
    EXPORTING
     text           = itstring
   IMPORTING
     BUFFER         = itxstring.

CALL METHOD cl_wd_runtime_services=>attach_file_to_response
  EXPORTING
    i_filename      = 'C:\temp\FILE01.txt'
    i_content       = itxstring
    i_mime_type     = 'text/xml'.

What do I do to rectify the code and get the file downloaded?

Best Regards,

Pankaj

I think you need topass MIME type correctly in CAPS.

Hi Nabheet,

I changed case of MIME type and get the same error. I guess the problem is with the reference semantics of data objects.

Thanks,

Hello,

Any idea on why the "NULL object reference" run time error should occur.

Open to all possible suggestions.

Best Regards,

Pankaj.
