Hi,

thanks for your replies in advance. Here is my problem:

I have set the backtrace option of my AntLRDelegating fragment in the
GenerateMyDSL file of my grammar "MyDSL" according to the instructions,
given here:
http://wiki.eclipse.org/Xtext/FAQ#Why_do_I_get_warnings_like _.22warning.28200.29:_InternalFoo.g:42:3:_Decision_can_match _....22_when_running_the_generator.C2.A0.3F

When I now try and run the workflow, this is what it says to me:

ERROR eclipse.emf.mwe.core.WorkflowRunner - [ERROR]: No getter or adder
method for property 'options' in clazz
'org.eclipse.xtext.generator.AntlrDelegatingFragment' found. Forgot to
customize?(Element: bean options in
/home/oba/Desktop/workspaces/KIELER_KIT_Galileo/org.xtext.ex ample.textualsc/src/org/xtext/example/GenerateTSCL.mwe:33;
Reported by: -UNKNOWN-)

Aprreciate any help!

Thanks
mN

Hi Ilyas,

the FAQ contains a bug. You have to use the XtextAntlrGeneratorFragment
directly if you want to use backtracking. Please change the classname in
your workflow to
de.itemis.xtext.antlr.XtextAntlrGeneratorFragment.
Also note that you'll have to enable backtracking for the
XtextAntlrUIGeneratorFragment too.

I'll update the FAQ.

Regards,
Sebastian

Sorry I've been confused, you are not Ilyas, but mN ?
