LineDecorator.decorateLine(int) never call

I want to add extra information to annotated views of files, and to diffs using a Gutter Renderer Module.

It seems that the DiffLineDecorator works but not the LineDecorator: method LineDecorator.decorateLine(int i) is never call.

Details

I've created the GutterRenderer, the DiffLineDecorator and the LineDecorator.

• When I go on a diff page:
  • GutterRenderer.getAnnotationDecorators(DiffType diffType, String repository, String fromPath, String fromRev, String toPath, String toRev) is called, a single element list of DiffLineDecorator is returned
  • DiffLineDecorator.decorateLineXXX(...) is called
  • The gutter is visible with the html specified in decorateLineXXX methods.

• When I go on an annotated file:
  • getAnnotationDecorators(String repository, String path, String rev) is called, a single element list of LineDecorator is returned
  • LineDecorator.decorateLine(...) is never call
  • The gutter is not present on the file
