Create views fields from taxonomies for my module

Hello to all.

I would like to ask you a solution, and of course your help, for a problem that I have.

• I created one module where I create some forms for the users to complete. There are also fields with terms from taxonomies.
• I created a tables in the database called "cvprofile" which among others has the following fields "cvid, uid, ..."
• I created a second table which has the relationship between "cvprofile" and "term_data". There are three fields, "cvid, tid, vid". Here I store the terms the user selects in the forms.

• I also made one of the fields to work with views by using the following code (a part of the whole code, at least)

  $data['cvprofile_terms']['table']['group'] = t('CV Terms');
  $data['cvprofile_terms']['table']['join'] = array(
  'term_data' => array(
  'left_field' => 'tid',
  'field' => 'tid',
  ),
  );
  $data['cvprofile_terms']['tid'] = array(
  'title' => t('Terms'),
  'help' => t('The terms user selected.'),
  'filter' => array(
  'handler' => 'hs_taxonomy_views_handler_filter_term_node_tid',
  ),
  );

The "hs_taxonomy_views_handler_filter_term_node_tid" is a handler from the "Hierarchical Select" module. This works just great even if I want this field exposed. But the problems started when I tried to add the second taxonomy in the views. If I add a second code like the above, it overrides the first and the view does not work good.

Is there a solution on that? Is there any dosumentation or example code that I should read to find the solution?

Thank you all for your time...
