Symptoms

When adding or editing a multimedia macro to a page, the attachments list is empty. This happens when the page title contains a colon ":" character. Other non-alphanumeric characters do not seem to have the same problem.

Steps to Duplicate

1. Create a page containing a ":" in the title
2. Attach a multimedia file to that page
3. Try to insert a multimedia macro on that page

Workaround

There are two workarounds:

1. Remove any colons from the title. This will cause the files to appear in the list.
2. Drag and drop the file from a local folder to the editor window. This will bypass having to select the file name from the list.
