OpenGraph: custom properties not showing in post

Question

I've create a Custom Object/Action/Aggregations for my app.

https://graph.facebook.com/10151038251679973

All is working fine but now I wanted to add custom properties for my object.

I've successfully added two properties: when and facility.

The problem is that when I share the object (i.e. posting the link on my wall) the custom properties does not show up.

Any idea? I have to do some additional configurations?

Custom properties are not showed for just posted object, but you can display 'em with your actions. You should specify something like {match.when} in the "Caption" field in Action Settings (Configure story attachment section):

Once action referencing match object (and caption as described above) published you will see something like this:

BTW, Some notes regarding warnings you see in debug tool related to Date format:
Currently where is no way to get rid of that message other that provide numeric timestamp instead of ISO 8601 date (none of samples or formats described for DateTime in Simple Types are working without a warning) . The good news that date is updated correctly even if warning displayed, so you may ignore such warning as long as timestamp displayed in Object Properties of Debug Tool output is correct and represent your actual date. There is couple of bugs exists for that issue: #159315504193810 and #302542186507947
