Namehash BLENDTREE in Substate

Hi.

I'm able to hash an animation state within a substate, but unable to do so with a blendtree in a substate. It is possible? Any tricks?.

The blendtree state is the idleState and should print Idling in the console but never does unlike the croucgState witch does work.

Here my code:

 public class Player_Movement : MonoBehaviour {
 
     public static Animator anim;
     private AnimatorStateInfo stateInfo; 

     int crouchState = Animator.StringToHash ("Crouching.Rifle_CrouchLoop");
     int idleState = Animator.StringToHash ("Standing.Idle_And_Rotate_Blend_Tree");
   
 
     // Use this for initialization
     void Start () {
         anim = GetComponent <Animator>();
     }
     
     void Update () {
 
             //miramos cual es el state dentro de la layer 0, la Base layer.
 
 
         if (Input.GetKeyDown (KeyCode.C) )
             anim.SetTrigger("IsCrouching");
 
         stateInfo = anim.GetCurrentAnimatorStateInfo (0);
         if (stateInfo.nameHash == crouchState)
             Debug.Log ("crouched");
 
         if ( stateInfo.nameHash == idleState )
             anim.SetTrigger("Idling");
     }
   
 }
