As part of the accessibility requirements of a list view it is essential that the table has a caption that describes the table, the sort order and any filters.

The first two of those are already done.

While investigating a method to do the filter part I saw that the two filters related to workflows (stage and condition) do not set the activeFilter

To test add this code to the top of the article list view

<?php $this->activeFilters = $this->get('ActiveFilters'); ?>
<?php print_r($this->activeFilters); ?>

Now when you select a filter it should be displayed by the code above.

It works perfectly for all the filters except for two filters related to workflows
