I've been developing in eclipse with the flex builder plugin, and a few months ago we upgraded to the flex sdk 3.3. Since the upgrade when we set the sdk to 'Flex 3.3' in the IDE we lose the ability to use the design view. We get the following error:
"This Component is based on HBox, which is not a visual component. Switch to source mode to edit it."
This happens to all visiual components not just the HBox. I was wondering if anyone else has seen this error, and if there is a solution?
For now we just drop the sdk back down to 3 whenever we need to use the design view, but it would be nice if we didnt need to do this.
