Manage External Data Sources dialog in Yosemite doesn't show data sources initially

Issue report by William Porter

Product

FileMaker Pro

Version

13

Operating system version

OS X 10.10 (Yosemite)

Description of the issue

I have a two-file solution. Data file is hosted remotely; the front-end or UI file is stored locally on my Mac. When I open File > Manage > External Data Sources, the list of external data sources is initially blank, even though I am in fact connected to the remote data file and viewing its data. To see the data source in the list, I have to click on the View By menu. Then the data source will appear.

Steps to reproduce the problem

See description. Summary:

• Host external data source remotely, and UI file locally
• Go to File > Manage > External Data Source

Notice that it's blank.

Expected result

The external data source was defined long ago and is in fact being used. I expect it to be visible when I open this dialog.

Actual result

It ain't there.

Configuration information

Mac OS X v10.10 (Yosemite, latest public beta as of 9-24-14).
FileMaker Pro 13.0v3

Workaround

Fiddling with the View As menu in the manage data sources dialog will prompt the data source to be displayed.
