Metadata from Text File importer requires use of file Browse button even though file can be entered manually - Finish button is enabled

I was writing a SWTBot test to create a view model's tables when I ran into this.

Knowing SWTBot can't handle the File Chooser, I was delighted to see I could enter the text file's path and name directly into the importer dialog. It wasn't until some time later that I realized merely typing in the name does nothing; you MUST enter the name using the File Chooser. (Once that's been done, it appears you can use the drop-down to re-select that file, but you need that first time entry.)

What's really bad/confusing is manually entering the file and target location enables the Finish button. Clicking it appears to work, but no tables were added to the model.
