entity reference and exposed filter Hello I would like to ask about views and exposed reference filters. I have problem with displaying my custom view for exposed filter. Can you please help?

Its kind of complex so I will try to describe the structure. I made view which should be used as exposed filter and this view works fine, but cant push it to appear in other view as exposed filter.
All of my users have some cateogies as taxonomy terms. Also every content has this category so I want to show to user only the content which is in category assigned to specific user. There can be more than one category assigned to user. Content has also single value entity reference to manufacturer.
And now I need to have a page for every content type where and I want to display all content in users category with exposed filter of manufacturers. In this filter must not be all manufacturers but only which ,there is content created with this manufacturer and the content is assigned to same category as the user.

Little example for one content type:

  user1 - category: dj, profi video
  user2 - category: hifi
  user3 - category: dj, hifi


  content1 - manufacturer: m1; category: dj, hifi
  content2 - manufacturer: m2; category:dj
  content3 - manufacturer: m2; category: profi video
  content4 - manufacturer: m3; category: hifi

In this point the exposed filter for user1 should display: m1, m2. Or for user2: m3. Or for user3: m1, m2, m3.
You need to set up relationships between the three content types in your View. Essentially, you have to set up relationship user->category, then relationship category->manufacturer, at which point the manufacturer fields will become available in the exposed filters section. There is a great tutorial here how to do this.
