Why is the rendering-definition of my Mask-Content-Element missing?

Question

I have created some CE types with ext:mask and if I insert a CE in the page in the FE this error appears:

Content Element type "mask_my_own_ce" has no rendering definition!

I have inserted the static template of mask, and just edited the generated fluid template

Answer 1

The Fluid Styled Content Static Template has to be included before Mask Static Template, otherwise no mask-elements are shown.
