SaveAsDialog, Filter, and FileTypes oddity

I noticed the other day that Answers wasn’t behaving properly when you changed the state of the Hide Extension checkbox. I ended up playing with it a lot this morning and discovered the issue, but I’m a little surprised.

It turned out that using the FileTypes object to set the Filter on the SaveAsDialog did nothing. At all.
I defined a file type in code and set the filter to that filetype object and suddenly things began working as they were supposed to.

This is using entirely classic framework code.
Has anyone else seen this behavior?

There is indeed a bug apparently in Xojo where the filter in GetOpenFolderItem does nothing.

It used to be fixed in RS, though

I just tested that case and verified that is in fact fixed. I also tested adding a file type to the project with the extension set to “pdf” and that also worked correctly.
