How to properly use two contextual filter for taxonomy this is my case:


I have a content type called "norm".
Each norm has two fields with taxonomy terms: "issuing institution" and "norm type".
Each taxonomy field has its own vocabulary.


I'm making a View that will:


Filter all the "norms" that are issued by "institution A" or "institution B".
Has two contextual filters. One for "insitution", second for "norm type".
If the first parameter is not given, just show a summary with the instituions (in this case, just two institutions). [This is working]
Then, if the second parameter is not given, just show a summary with the "norm type". I mean this will be a list of norm types that has been issued by institution %1 (first parameter).


But, the last is not working. It shows again the instituion.

How can I do this kind of thing?
This happens because the views checks the first parameter and the first parameter overrides the second parameter. In your case, if you rearrange parameters so that parameter 2 comes before parameter 1, you will see this time views working with parameter 2 and not with parameter 1.

You can fix this behavior by creating two separate pages in views and each page will override the behavior of the other by selecting For:"This page(override)" option.

In the first page add the two contextual filters(parameter 1 and parameter 2). While adding the contextual filters you have to select For:"This page(override)".

In the second page of the views, add the two contextual parameters, this time add parameter 2 before parameter 1. In this case also, while adding the parameters you have to select For:"This page(override)".

Good luck!
