Calling a custom tcode using abap class from workflow

Question

Hi Experts,
I have a requirement of calling a custom tcode from my workflow.
For this i have created a class zcl_test ( has if_workflow ) .
I created a method ztest which will call the tcode.
CALL TRANSACTION 'ZTX'.  ( My tcode just has 1 input field, for testing purpose )
Then i created a task in whichi hv used this abap class and method.
But the tcode does not run when i execute the workflow.
Please help.
Thank You,

use the sample code to get the data from the task container into the ABAP class
DATA :
         w_ref        TYPE  REF TO      if_swf_run_wim_internal,
         w_ref_cnt  TYPE  REF TO      if_wapi_workitem_context,
          w_wi_ref   TYPE  REF TO      if_swf_ifs_parameter_container.
TRY.
    CALL METHOD cl_swf_run_wim_factory=>find_by_wiid
      EXPORTING
        im_wiid     = w_wiid
      RECEIVING
        re_instance = w_ref.
  CATCH cx_swf_run_wim_enq_failed .
  CATCH cx_swf_run_wim_read_failed .
  CATCH cx_swf_run_wim .
ENDTRY.
CALL METHOD w_ref->get_workitem_context
  RECEIVING
    re_ctx = w_ref_cnt.
CALL METHOD w_ref_cnt->get_wi_container
  RECEIVING
    re_container = w_wi_ref.
and the w_wi_ref is having a method GET use that method to get the values of the task container into the ABAP class.
