Advanced search and dropdown fields

[tportier]

If you make an advanced search on a field that propose a dropdown (databasejoin, dropdown, checkbox, radio) and select more than one choice with an "Or" on the same field, if you launch search and you navigate throw the pagination or change number of result per page, only the last element of the search is kept.
For exemple if I'm looking for records on a municipality "Or" on an other municipality, I'm loosing the first search item if I navigate throw the pagination.
