JSF Design Time View Not working correctly for ADF/JSF components

Question

My project is not using any external tag libraries. It is based purely on ADF core/html and JSF core/html components. The design time view does not show the appropriate presentation, everything is shown as nexted frame containers (I suppose how you would show a component that does not have a visual representation).
If I create a new project and copy my jsp (jsf) pages over they show perfectly. I did this activity and all was going well in the new project and then I lost the design time view again. I cannot tell you what I did to cause the issue, maybe it was a modification to the web.xml as has been suggested in some other threads. Can anyone tell me what I should be looking for that causes this problem, what corrective actions I might take to eliminate the issues

Answer 1

Ok I have isolated this issue. In my phase listener I had this line of code:
private static final Logger _logger =  Logger.getLogger(EigRequest.class.getPackage().getName());
and I changed it to
private static final Logger _logger =
Logger.getLogger(EigRequest.class.getName());
and design mode started to work. I guess either of the above works for me although I do not understand why the line works when you run the application but not in design mode.
Moral to the story is if something fails in any one of these types of decorators you will drop into a raw view mode. The question I have is if errors are occuring how do I figure out where they may be. There is no indication that anything is wrong with the exception that you lose most of the design mode functionality.
This was not a compile issue, this was not a runtime issue. It took me quite a few hours of writing a test program to validate that it was not just writing a phase-listener issue; then launching, editing, relaunching the application to find the problem. I will say that a good portion of the code came from a Eclipse project. If you add the offending lines of code while using JDeveloper you do not loose design mode immediately. You only see the problem the next time you start JDeveloper which complicates finding the problem.
