After building a custom web template (in code). I assign the custom web template in Power Pages Management Studio (PPMS) to a page template (that uses the custom web template) and then build a new page based on the page template from the web template. I find I cannot edit the new page (based on custom templates) in the design studio. Now I think it might have something to do with the liquid code {% editable %}. Any ideas as to allow the PP design studio work with custsom templates/pages?
