setState

void setState(Question.State state)
              throws UnauthorizedException

Sets the resolution state of this question. Rules for who is allowed to set the state of the question are as follows:

• Only the question creator is allowed to set the question state to Question.State.open. Typically, this would happen when the state has been set to Question.State.possibly_resolved or Question.State.assumed_resolved but the user wants to indicate that the question is still not resolved.
• Anybody can set the resolution state to Question.State.possibly_resolved as long the state was previously Question.State.open and there is at least one message posted in the thread after the question creation date. Otherwise, only a user with moderator or higher permission can set the state to Question.State.possibly_resolved.
• Only a user with moderator or higher permission can set the state to Question.State.assumed_resolved as long as the state was not previously Question.State.resolved.
• Only the user that created the question can change the state to Question.State.resolved.

When to set the state is left open in order to accomodate a variety of workflows and business rules. However, the typical rules are as follows:

• Set the state to Question.State.possibly_resolved when a new message is posted in the thread if the current state is Question.State.open.
• Set the state to Question.State.assumed_resolved when a support agent posts an answer to the question that they believe is correct. Or, when the user has abandoned the question and a moderator decides that the question is answered.
• Allow the question creator to set the state to Question.State.resolved when a helpful answer is added to the question. Encourage the question creator to set the state to Question.State.resolved when a correct answer is set. Allow the user to set the state to Question.State.resolved at any time; for example, if they solved the problem themselves or independently of the forums.
