FileMaker 12 brings new features to container fields. In this webinar we presented several new features and showed how we could use them to design better applications.
Most important among the new tools are:
Externally stored container data: Reduce the size of your databases and stream data to users for faster performance.
Validation For Container Fields: Prevent users from uploading files that are to big or of the wrong type.
Inspector Options: New options to controlling streaming and content viewing for container fields..
Insert File Script Step: The improved insert script step allows us to more tightly control how a user inserts data into container fields.
Plug-in Updating: The new container fields work in conjunction with the new script step to install plugins right from your solution.
