I will look into the nested snippets. For expediency, I folded all the snippets that interact with my template into one file, so I can concentrate on the business logic.
For my Todo app enhancement, I need to pass the id of my selected Tag (which I have confirmed is correctly gathered from the page request) in to the TD.list method, so that the filtered Todos (those bearing the required Tag) will be found and rendered. My problem is that if I try to pass an additional argument (tagId: Long), the TD.list method is not happy and will not even render the template. I have tried both paired (html: NodeSeq, tagId: Long) as well as curried style (html: NodeSeq)(tagId: Long), but neither works. There must be a simple way to accomplish such a common task!
