I work on a portal solution and one fonctionnality of this one is to be able to drag&drop components.
For a demo component, I wanted to create a component that embed the twitter widget API. So the final user just have to feel his widget ID for add new twitter component to his portal.
The twitter script generate an iframe, no problem with that. The iframe generated doesn’t have src attribut (don’t know why), and in HTML all the drag&drop solution that exist actually (HTML5, jquery ui, yahoo ui, …) reload the iframes that are drag&droped in a page. When the twitter widget is drag & droped it display a blank iframe because his iframe is reloaded and this one doesn’t have src.
I don’t see other solution than reload completly my component after this one was droped but it’s a greedy solution. Because it’s will impact all my portal behavior just for handle iframes that doesn’t have src attributs (and I see only the twitter widget for now).
If anybody have faced the same issue or have a feedback on a possibly better solution than mine is welcome.
