Showing layered navigation filter in two block locations - will only render if in one XML block
I have the XML below in my layout. Notice that both category.products and product_list have the block type amshopby/catalog_layer_view_top. The reason for this is that under certain conditions category.products will render this block and in all other circumstances product_list will render the block. If I remove one of the references to this block so that it is only in my XML once, the block renders its content. When it is in the XML twice, a method within the template (canShowBlock) becomes false and the content does render.
