After some tedious trial and error testing, I have found that the reason my tooltips were totally missing is because the touchkit addon was being included in the widgetset for my non-touchkit app. With the benefit of hindsight, one might have thought to look in that direction at the start since touch screen apps have no mouse-over tooltips. My eclipse project still includes Touchkit and non-Touchkit code, but the widgetsets are now built separately for each entry point.
Vaadin 7.2.2 still shows improper styling of the tooltips, but that has been reported in other threads. The attached image shows what I get instead of the normal yellow rectangle. This is no doubt related to the error which shows up in the browser debug window: “Could not determine ApplicationConnection for Overlay. Overlay will be attached directly to the root panel”
We use an extensive theme/stylesheet which inherits from Reindeer.
Hope this report helps others.
