What I meant to say is that when capturing from Safari into DTP, DTP will not display any of the body text (the articles), only the black background that is normally behind them. It’s like the page is “empty”, except that you can still see the sidebars and the header. When I capture from DA into DTP, everything is just fine.
I’ve seen this phenomenon before, with dynamically-changing (“push” technology?) Web pages like Slashdot’s.
I’m more likely to see the full page including text if I capture the WebArchive from DEVONagent using the contextual menu option, compared with clicking the Archive bookmarklet button in Safari (perhaps a matter of timing during the capture?). But sometime the WebArchive captured from DEVONagent will also look incomplete.
If repeated WebArchive captures are made from the Slashdot page, the most recent capture may show only a black screen where the text should be. Strangely, once that has happened, the previously ‘good’ captures now display that black screen.
But the text data really was captured, as can be confirmed by selecting a different document, turning off AirPort, and once more selecting the Slashdot WebArchive. Now the text is displayed!
Is this a WebKit bug? An artifact (bug) of the WebArchive format? I don’t know, but I can replicate it on several sites, including Apple’s main page.
