error :

**

"exceptionmessage": "multiple actions found match request:

**

the first route have registered restful style route, doesn't include {action} segment.

as routes evaluated in same order registered, whenever send post request, controller name taken url, , then, action selector action name starts post. in case there 2 actions fulfill condition: postsavebook , postsavemobile.

if first registered route "controllerandaction" one, action taken url , action selector correctly choose desired action.

if want use restful style, you'd have use attribute routing break ambiguity.
