Get a node using the same category (taxonomy term) the current node is using I have two types of nodes: News and Page. 
Every News node can be assigned to a category (taxonomy term), which is used also from the Page nodes.

I would like to get in a view all the News nodes that have the same category the current node has.

How can I achieve this?
Add CONTEXTUAL FILTER (Earlier arguments) on CONTEXTUAL FILTERS section on views click add, select "Content: Has taxonomy term ID" and in "WHEN THE FILTER VALUE IS NOT IN THE URL" choose Provide default value. Choose "Taxonomy ID from URL" check "Load default filter from node page, that's good for related taxonomy blocks". It will create a related taxonomy.
