I have an issue that shadow cannot pass thru refaction enabled object.

I have setup a very simple scene:

3 objects
1 solid lamber shader object on the bottom
1 transparent phong object with reflection and refraction turned on, transparency to 100%
1 object at the top with the same solid lamber shader

1 light casting shadow
mental ray with raytrace shadows on

I've made sure that it cast shadow on the render while I have the refraction check off. As soon as I check it on there has no shadow going casting on the bottom object.

I've tried many settings which still doesn't work.

Need urgent help plz
