Hi Vaadin Team,
we are using a Custom Component Widget in a TabSheet. The Widget uses a native Javascript library to display
tree like data which is creates DOM elements dynamically. The Component is placed in a TabSheet Tab and once triggered the Tree is correctly displayed.
When changing to another Tab and back to the Tree`s Tab only the parent DOM element is restored! The childs, a HTML5 canvas and label container DIVs gone missing. We cannot figure out how Vaadin stores and reloads the Tab’s content. What happens with the content when a Tab is changed we did not find anything in your API.
The Tab just works fine with other contents, which also have many DOM childs. I hope you can help us with this issue, we can provide relevant Code if needed.
