OnCustomActionExecuteAction display message box

[John_Sommervill]

Which implementations are able to display message boxes?  I have a custom action that executes on a Unity Form, and found an edge case where I need to notify the user to take an action outside of OnBase.  I attempted using the MessageBox with the OnCustomActionExecuteAction script, but received this error:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application. 

Any ideas on how I can deliver this message to the user from this Unity Form?

Thanks!

Custom Action scripts run on the server. The best workaround I found id to display a message on the form.

This is correct, and likely the best workaround.
