TSShapeConstructor not working for .cached.DTS

guys,
I have this problem: I have setup my model to use DAE and its animations work flawlessly.
But when I decided to change everything to use the cached DTS file instead of DAE animations stopped working.

For clarification these are the objects datablock and its *.cs file with the ShapeConstructor with DAE (that works) :

datablock StaticShapeData(MyShape)
{
   category = "MyShape";
   shapeFile = "art/shapes/myShape/myShape.DAE";
};

//in the myShape.cs:
//--- OBJECT WRITE BEGIN ---
function myShapeDAE::onLoad(%this)
{
   %this.addSequence("AnimationClip", "root", 0, 25);
   %this.setSequenceCyclic("root", "1");
}

singleton TSShapeConstructor(myShapeDAE)
{
   baseShape = "art/shapes/myShape/myShape.DAE";
   upAxis = "DEFAULT";
   unit = "-1";
   lodType = "DetectDTS";
   singleDetailSize = "2";
   ignoreNodeScale = "0";
   adjustCenter = "0";
   adjustFloor = "0";
   forceUpdateMaterials = "0";
   canSaveDynamicFields = "1";
};
//--- OBJECT WRITE END ---

And these are the changed files to use the cached DTS file:

datablock StaticShapeData(MyShape)
{
   category = "MyShape";
   shapeFile = "art/shapes/myShape/myShape.cached.dts";
};

//in the myShape.cs:
//--- OBJECT WRITE BEGIN ---
function myShapeDAE::onLoad(%this)
{
   %this.addSequence("AnimationClip", "root", 0, 25);
   %this.setSequenceCyclic("root", "1");
}

singleton TSShapeConstructor(myShapeDAE)
{
   baseShape = "art/shapes/myShape/myShape.cached.dts";
   upAxis = "DEFAULT";
   unit = "-1";
   lodType = "DetectDTS";
   singleDetailSize = "2";
   ignoreNodeScale = "0";
   adjustCenter = "0";
   adjustFloor = "0";
   forceUpdateMaterials = "0";
   canSaveDynamicFields = "1";
};
//--- OBJECT WRITE END ---
