Hi Tobias Another point to bear in mind: the entire widget tree (and hence DOM tree) may need to be destroyed and recreated at any time as part of a refresh cycle.
> To me, this is not about states, it is about but temporarily manipulating a representation, a simple action that does not require storing whatever changes to the output were made. Meaning, I do not need to remember the last triggered start (or end) position for the video. Instead, I just need that button / link to trigger a redraw of the associated iframe to have that player / video set to the desired parameters. This information does not need to be stored as a state and can be happily discarded, can it not? In other words, we are entirely working with the DOM at this moment, are we not? Embedding a YouTube video as an iframe is already problematic. Try playing a video on tiddlywiki.com and then change the language setting while the video is playing. The video will reset back to the beginning. That's because the video player has state (whether it is playing or not) that is not restored after a refresh. The fix would be for a YouTube widget to store in tiddlers the position within the video, and whether it is playing or not. Then the widget could restore the video to (almost) the correct point. If the widget also responded to changes in those tiddlers then we'd have a very flexible basis for controlling and manipulating videos. Best wishes Jeremy.
