I'm just getting into the omeka code, so sorry if this is an obvious question. I'm trying to tweak the item metadata display, so I copied application/views/scripts/functions.php to my theme directory and made some changes to custom_show_item_metadata(). But this seems to have no effect.
When I temporarily made the same changes to the original (in the application directory), they work just fine, but undoing those changes and adding them instead to the theme's copy of functions.php doesn't do anything. What are the general rules for overriding base application scripts with new files in the theme directory?
