Whenever I try to create a link to a page that is in a namespace, the link does not get created.
I am doing this from the WYSIWYG editor (have disabled non WYSIWYG editing). When I go to create a link, it lets me type in part of the page name, and I get a list of pages to choose from. Pages that are in a namespace have a colon shown between the namespace and the page name, regardless of the actual separator. I select the page from this list, so there is no way I could be typing anything wrong.
I have tried this using different separator characters: the default ":_:", also ":" and "_", all with the same effect. If I go to "Source" mode right after inserting the link, there is an anchor with no href attribute. If I try to change an existing link, the href gets change properly, but I cannot click on it in the WYSIWYG editor or preview, and when I save and then go back and edit, the href has been removed.
Surely there must be some way to create a link to a page in a namespace. What am I doing wrong?
