HTTP Error 411 "Length Required" when I try to call a service via POST

hi all,

 

i've got service want call within flex, , used data/services tab setup new service call.  it's called "commitchanges" , it's supposed cause server commit changes submitted, incrementally, during session.  can think of being "save" command.  takes no arguments.

 

in keeping suggested use of post operations causes changes data on server, setup request use post.  however, when try call service following error:

 

response received:

 

length required

---

http error 411. request must chunked or have content  length.

 

if change request type works, i'd working post.
