spworkflowtaskproperties.extendedproperties aren’t populating fields task

i am attempting pass information assign combined within workflow the analogous assign form. before createtask activity, i emanate an spworkflowtaskproperties fill common info (title, assigned-to, etc). i also supplement elements extendedproperties property. however, those tradition properties never task.

i've attempted sourroundings ability pivotal to:

• the guid task' content
  type's fields;


• the middle name of
  one task' calm type's
  fields;


• an separate name (in the
  hopes removing info the
  task's properties instead its
  fields).

nothing works. task, once created, contains wholly built-in domain values i have set. zero values i definitely total extended properties arrangement up.

the (simplified) method activities follows:

• preparetask. custom
  activity contains the
  spworkflowtaskproperties


• createtask. assign properties organization preparetask activity.


• ontaskcreated. assign properties organization preparetask activity.


• while (task complete)
  
  
  
  
  • ontaskchanged
  
  

i am controlling wss 3.0 sp1 an aspx (not infopath) assign form.
