    Un Unknown Item is Declared as the Root of your MXML

      I've seen numerous posts about this online. this is a bug with Flex Builder. I've reinstalled several times. Sometimes it works, but sometimes it doesn't. I can't tell if it is a spacing issue or something else.

      Symptoms: Code highlighting and assist stops working and you can't use design mode.

      Solution: Bang your head up against the wall. Restart flex a few times. Delete everything from the file and paste it back in. Restart you computer. Eventually it will work. This can happen with an existing document 3 miles long or a brand new component you create. I've had this happen on two different PCs.

      Google search results on the problem.
