Thumbnails for WebResources
I've got a question about thumbnails. When creating a FeedItemUrlExtractor, you can pass a thumbnailUrl to the ContentURLContainer returned by extractUrl.
When creating a WebResourceUrlExtractor, you can do the same. However, with the WebResourceUrlExtractor, you can also add a thumbnail to the WebResourceContainer returned by extractItems method. It seems that the WebResourceUrlExtractor ignores the thumbnails specified in the ContentURLContainer, and returns the "global" thumbnail for all items, as returned in the WebResourceContainer.
I'm not sure if this is by design, or if this is a bug. It's also possible, of course, that I'm doing something wrong. The plugin which has this issue is the Uitzending Gemist plugin, posted here.
