I'm trying to transition a site from DTML to ZPT. I have some ZClasses that I would like to use "as is" until I get a chance to rewrite them. When I try to display an object in a Page Template, it fails (the Zlcass instance is called "bubbles" and is a folderish object with a few properties and contains a Photo Here is what I try to make it work: <span tal:replace="structure container/bubbles"/> Result is the page is rendered with nothing where the object should be. If I view the source of the rendered page I see <highlight at bubbles> where the object (a highlight named bubbles) should be. Then I tried: <span tal:replace="structure container/bubbles/index_html"/> Result is: Error Type: NameError Error Value: global name 'caption' is not defined "Caption" is a property of the object. index_html is a DTML method Am I trying to do the impossible, or am I missing something?
