This problem can occur on any platform.
After following the instructions in the Best Practices Guide to use getInstanceID(), you see that
it works in the runtime environment. However, when you're in JDeveloper, the use of getInstanceID() throws an error which disables the Design tab. The Design tab and the Mapper Messages log tab both show errors.
In Design Tab:
Error: XSL Map generation failed. Please use the source editor to correct the problems and return
to the design editor.
Mapper Messages log Tab:
Line Number:(41):Invalid XPath expression (null)
