[away3d] Away 4 ResourceManager parsing embedded model error

[MADCATX]

Hello, I'm trying to load embedded model files, but  without success.
Following code produces error:

[Embed(source="model.3ds", mimeType="application/octet-stream")]
private var modelObj:Class;

public function LoadModel() :void
{
        ResourceManager.instance.parseData(new modelObj(), "model", true,
Max3DSParser);
}

Error Thrown:

Error #1034: Type Coercion failed: cannot convert
ResourceLoadSession@1f82c151 to away3d.loading.IResource.
Fault, ResourceManager.as:179

The following code works alright:

public function LoadModel() :void
{
        ResourceManager.instance.getResource("model.3ds", true);
}

Most models in .obj format seems to be parsed properly when using
embedded model, but some models still throws error. 3ds files always
throw error when are being parsed from embedded file.
