Problem when customizing frontend product show.html

[hapax94]

Using solidus1.2, I tried to customize frontend product page with related_products.
I get the following error:
Showing /Users/hapax94/sld/testum2/app/views/spree/products/show.html.erb where line #1 raised:
undefined local variable or method `current_pricing_options' for #<#Class:0x007fba4da55ed8:0x007fba43477c78>

When I removed the first instrcution <% cache [I18n.locale, current_pricing_options, @Product] do %>, it works.
