I want to try out xText, so started with a really simple grammar:
Entity :
"entity" name=ID;

But I still get a warning message:
...//my.dsl/src-gen//org/example/dsl/parser/mydsl.g:128: warning:lexical
nondeterminism between alts 2 and 3 of block upon
...//my.dsl/src-gen//org/example/dsl/parser/mydsl.g:128: k==1:'\r'
...//my.dsl/src-gen//org/example/dsl/parser/mydsl.g:128: k==2:'\n'
...//my.dsl/src-gen//org/example/dsl/parser/mydsl.g:128:
k==3:'\u0003'..'\ufffe'
...//my.dsl/src-gen//org/example/dsl/parser/mydsl.g:128:
k==4:'\u0003'..'\ufffe'
...//my.dsl/src-gen//org/example/dsl/parser/mydsl.g:128:
k==5:<end-of-token>,'\u0003'..'\ufffe'
...//my.dsl/src-gen//org/example/dsl/parser/mydsl.g:128:
k==6:<end-of-token>,'\u0003'..'\ufffe'

How can something so simple be nondeterministic?

Second question: Assuming this warning isn't enough to cause editor
generation to fail, how do I run the generated editor. The tutorial
says something about Eclipse knowing to use the editor for any file with
the right extension (.dsl), but that doesn't seem to work on the example
I'm trying. Am I missing some configuration step?

Thanks for any help.
