Problems Starting Richfaces Screens.
Okay, I'm having a few really weird problems. I'm getting some very unusual behaviro out of my screens and I'm really not sure what's going on.
I'm a bit new to Richfaces and no doubt my problems are caused by me. However, I would really appreciate a pair (or two) of expert eyes to give me some suggestions on what I did wrong. Or general suggestions on how to improve my code.
First, I'm using Richfaces 4.3.0.Final on JBoss 7.1.1 AS.
When I first load the screen, I get the following error message:
| Load Error Message From JBoss 7.1.1 |

HOWEVER, the screen does load and seems to be formatted correctly.
So, I enter in my order number and hit the "lookup" button.
The first time I press the Lookup button nothing happens. HOWEVER, the second time I press the Lookup button everything works fine. In fact, from this point forward the screen works great.
I am totally confused...
Below is my main index.xhtml. I'm sure I'm doing something simple that I can't see. I would really appicate a quick glance by the experts!
