Recently there has been discussion in the FileMaker community regarding a known problem with live development (i.e., modifying database schema while other users are connected to the system). The problem is that under certain circumstances, the “New Record” command and script step will fail.
The aim of this article is to identify some specific circumstances under which New Record will fail, and also identify some specific circumstances under which it will *not* fail, and is based on a series of tests conducted using FMS 13v1 and a couple clients running FMP Advanced 13v3.
Disclaimer: These are preliminary findings and do not claim to be exhaustive or conclusive. If you are doing live development, you should test for yourself and draw your own conclusions.
Methodology: A system with two tables, Sales and Employees, was used. For all tests, the developer opened Manage Database and then did something (or in the case of the first test, nothing), but then did not click OK — instead the Manage Database dialog was left open. In no case was the “OK” button clicked.
