sdk - CRM2011/JScript: SetStateRequest (changing statuscode) - other fields' changes didn't save -

i have form statuscode has changed when button used. altogether status other fields has changed (from empty), filling information form has been accepted , current date.

the button action code below:

if (comment != null){  setvalue ("senddate",new date());  setvalue ("decision",100000000); //option set  xrm.page.data.entity.save();  sdk.rest.setstaterequest("entityname", xrm.page.data.entity.getid(), 0, nextstatus, ribbonbuttonsuccsesscallback, genericerrorcallback); } 

the problem after using button can see, "senddate" , "decision" filled, right after performing sdk.rest.setstaterequest part go blank/null. must have changes on fields saved , visible.

i tried using setvalue on "statuscode", didn't work well.
