Because of the ´@extend´, the following rules has been created:
.o_form_view .o_survey_question_view_form .o_form_renderer .o_survey_question_validation_parameters
.o_survey_question_view_form .o_form_renderer .o_form_view .o_survey_question_validation_parameters
.o_form_view .o_survey_question_view_form .o_form_renderer .o_field_widget.o_survey_question_validation_parameters > *
.o_survey_question_view_form .o_form_renderer .o_form_view .o_field_widget.o_survey_question_validation_parameters > *
As you can see, no one match the selector where it should be applied;
.o_survey_question_view_form .o_form_renderer .o_survey_question_validation_parameters
This makes this ´@extend´ useless.
Steps to reproduce:
- Go to Survey
- Questions & Answers -> Questions
- In the form view, select "Date"
- Go to the "Options" notebook
- Check "Validate entry"
