I have created view which displays a list of nodes. I made a custom module with a function which calls db_query() to delete the specified node in the list. I made a Global:Custom Text field in the view which I made into a link to point to that function. The link works perfectly, the node is deleted from the database table, but now the view still lists a blank line (where that node used to be) which still has the Global:Custom Text field there. How can I get rid of this line completely?
