Error BME-99003 faces-config diagram

Hi there Neelixx... I can help you!!! :P
Hey, in your file system still existing your faces-config.oxd_faces, is in the WEB-INF folder, but in the JDeveloper is called only faces-config, and that is different to your faces-config.xml,
That problem had his start when you delete the jsp files who was pointing the navigation case in the diagram (faces-config.oxd_faces)....then....the thing that you have to do....is.....replace that faces-config.oxd_faces with a previous version and start from there.....you will cant save your faces-config.oxd_faces but...you have to go to the source of your old faces-config.oxd_faces and copy the source code (in compare files, or history of your faces-config.oxd_faces you will can find the source code)....you can copy that to a txt file, then...close your JDeveloper, and, via Windows Explorer you have to find the your faces-config.oxd_faces in your proyect and replace it from there......to do that you have to open your faces-config.oxd_faces of your proyect with a notepad and delete all, then you have to copy your old source code of your faces-config.oxd_faces into that file....save....open your JDeveloper and be happy....
PD:Take care to not add new navigation cases in your faces-config.xml until you can fix your faces-config.oxd_faces or that will not works again.....
if that not works i will try to help you, because, im not in my work now, and here i dont have JDeveloper, then if i remember good that can solve your problem, but if not, tomorrow morning i will can be sure.
And dont worry if this dont works....because that problem have a solution...i works unders version control and always happen that kind of things with our faces-config.oxd_faces and i always can rsolve it....
Take Care, good luck and bye!
