BME-99003: An error occurred, so processing could not continue.

Question

Got the error message below when working with my faces-config.xml file.
I currently have several JSF navigation cases labeled as "!NLS Error" (No Quotes)
Steps to create the error...
1. Create an ADF Faces project with 10-15 pages and navigation rules between each page.
2. Outside of JDeveloper, redo your folder structure on how you store your pages.
3. Inside Jdeveloper, update the source of faces-config.xml to point to the new location of the files.
4. Click on the diagram tab.
On my screen, the diagram for both the old and new files was appearing. When trying to delete the diagram for the old files, I got the error message. I cannot save the file faces-config.oxd_faces.

Also, report the problem on the JDeveloper forum on otn.oracle.com, or contact Oracle support, giving the information from this message.

Answer 1

To fix this issue, I performed the following...
1. Copy the xml from the faces-config source tab.
2. Delete the faces-config.xml file within JDeveloper.
3. Create a new faces-config.xml file.
4. Paste xml from step one into the faces-config source tab.
Really not that bad of an issue, I only posted because the error message directed me to.
