Codename One - NetworManager & Connection request - post/get can't be modified

Question

I get an error every time when the request is called. When I comment the line with request.setPost(false), I get some response from the server. Please explain why this error is appearing.

Exception in thread "Thread-6" java.lang.IllegalStateException: Request method (post/get) can't be modified one arguments

Answer 1

setPost must be invoked before adding any arguments. Just invoke it before all the addArgument calls. The actual error is:

"Request method (post/get) can't be modified once arguments have been assigned to the request"

In the current version there is a misspelling where it says one instead of once.
