[No Demo Store] Notice: Undefined index: value in views_handler_filter

this is a normal issue as there are some vocabularies not built (Collection, Gender, etc...)
So probably we'll need (to define) 2 different products pages.
One default to be used for no demo content with less specific filters, fields and one which overwrites the default as it is now.

possible solutions (AFAICS):

1. different views based on installation selection: demo, no demo, demo with additional
2. rework the filter to use all the categories that finds about the nodes if there´s no vocabulary selected

Maybe we need to find a way to alter just those specific vocabularies ?

solution proposal: to build a new views filter "Content: Product Display Has taxonomy terms (from Multiple Vocabularies)"
- provides only vocabularies defined as term references in the Product Display content types
- if there's no vocabulary selected, use all these vocabularies.

could be built within Drupal Commerce Product Reference, so it could be used without Kickstart distribution.
In Kickstart could be used with no selected vocabulary.

Using a the a Views patch #1716826-14: Content: Has taxonomy terms from Multiple Vocabularies Filter
i create a new filter Product Display Has taxonomy terms (from Multiple Vocabularies)
this implements my previous defined solution proposal.
here is the commit : https://code.drupalcommerce.org/#/c/397/

actually this new filter should be used also for the Products page.

ReBuilt the Products page view.
commit rebased : https://code.drupalcommerce.org/#/c/397/

change the Views patch : #1716826-15: Content: Has taxonomy terms from Multiple Vocabularies Filter
commit rebased

questions:

1. should this filter be part of Drupal Commerce?
2, should we change the Issue title: Product Display Has taxonomy terms (from Multiple Vocabularies) Views filter?

commit rebased https://code.drupalcommerce.org/#/c/397/

all it seems ok

Merged. Fixes our errors.

Assigning to me and setting "needs work" so that I can look into the Views handler.

Looked into this. Opened #1827622: Implement a custom category filter for Backoffice, remove the views patch.

Closing this issue.
