I'm setting up a site using Woven, and I've hit a strange problem. I've got a subclass of woven.widget.Widget called VolumeWidget, and that widget is used to display a list of links within a page. I've got another class called VolumeListWidget, the only purpose of which is to display a list of these VolumeWidgets. class VolumeListWidget(widgets.Widget): def setUp(self, request, node, data): for volume in data.get('volumes') or []: volume_model = VolumeModel(volume) volume_div = VolumeWidget(volume_model) volume_div.tagName = 'div' self.add(volume_div) VolumeListWidget's not working. Instead of displaying a <div> that contains all the stuff VolumeWidget is supposed to contain [as defined in VolumeWidget's setUp() function], it's displaying an empty <div/>. I'm not sure what I'm doing wrong, if anything, but it's too strange to tell. Example (along with some code) is available here: http://polynode.com:8889/content.rpy/testvolumelist To see a working example of VolumeWidget, go here: http://polynode.com:8889/content.rpy/testvolume I will appreciate any help anyone can lend me.
