Couldn't find method Follow

Hi

I followed the SimplestLanguage tutorial... and its failng in the last step...

Couldn't find method "templateMappingRule_SourceQuery_ AllTextConcepts" in SimplestLanguage.generator.baseLanguage.template.main.Queries or in its supers.

I send in attach 2 screenshots, one of MPS where you can see the error and the declaration of "AllTextConcepts" and the other of IntelliJ with the Queries (wich compiles fine) class opened.

This must be a basic error (since none else complains about it), but can't seem to find where did went wrong, any clue?...
