Unity3D Third Person Controller and Animations - unity3d

Question

My problem is that a custom walk animation I have set in the third person controller of Unity3D is not shown.
The animation is imported from a FBX file with the model#walk.fbx structure. I know the animation works, because if I use it as the idle animation it shows. On the other hand, it also doesn't seem to be an issue with the controller script, as it works fine with the prototype character.
It seems that the animation being played is the one selected in the Animation component (which has 'Play Automatically' selected). Any attempts to change the animation from the third person controller work for the prototype character, but not for mine.
I don't have nor want run and jump animations. With the prototype character I set the walk animation on each of those with no adverse effects. The controller doesn't turn off animation this way, seeing that there are no log entries in the console from the third person controller script. The relevant line with the CrossFade call is getting called.
Any clues as to where I could look next? Is it more likely an issue with the controller, or with the animation? Something else completely?
Update: Below is the code of my controller. It works fine when I use the sample model of the construction worker that is provided with Unity. The lines with _animation.CrossFade are getting called at the expected times. Using Play or Blend instead doesn't help. There are no errors logged in the console.
For our custom animations however it doesn't work. I am now suspecting the issues lies with the model. Unfortunately I am not at liberty to share a sample of that model. I've asked the animator for further details on how he created the FBX export. Are there any specific settings he needs to use for the model to work in Unity? It remains odd though that the animations do work if I add them indepently to the scene.

Update 2: The settings used to create the animations are in these screenshots. Are they correct?

Answer 1

Not (yet :-) an answer but I need more space and images.
Since 3.5 Unity3d the way to handle imports based on animation#model.fbx notation has changed and some people reported trouble (s. for example BIG Unity 3.5.0f1 problem with Skinned Rig - Major FAIL). The problem arises when a 2nd root bone comes to play but I could solve this by dragging the animations to the model file prefab (most of my animations are contained in the model and the remaining 2 are no big pain).
Just to be really sure that I understood your answer in the comments section right, you have something like this:
That means:
Within the character model the animations array contains all animations
The number of bones and all names are exactly like in your prototype character
If you open an animation view, you can see a read-only list of all animations of the character selected in hierarchy view
Assuming this is fine some more suggestions:
I can't see any place in the code where you set WrapMode.Loop or animation speed. Are you sure it is configured as Loop in inspector and is not overwritten somewhere.
CrossFade with no parameters assumes 0.3 seconds
What happens after the cross fade call? Does the DefaulTake stops playing?
Can you drag the Walk animation as default
Do you use different animation layers?
What output do you get when you set up Debug.Log ("Walk: " + player.animation.IsPlaying ("Walk"));
[Update]
Let's look at the import settings. Do you have Split Animations
checked and are there maybe wrong values entered at Start and
End like 1-1?
Regarding Toggling of IsPlaying: Please create more output about the AnimationState properties. Most notable speed, length, enabled, weight, ... I have a suspicion that the animation is too short or played too fast.
A walk animation that is no bone animation sounds a bit strange. On the other hand console would cry out loud if bone names are not matching. So I assume there is no problem now.

Answer 2

That is strange, can you post the source&demo?
You can try to check:
Check if the animation names and properties are set correctly in the editor.
Create an object without the controller and make sure the animations were imported correctly.
