Too many triggers firing on a single layout can conflict. However, triggers should still be considered as a last resort. With diligence, Script Triggers can be managed properly so they function when and where intended. Script Triggers also don’t fire in all scenarios, such as during an event in a web driven solution, while Manage Database functionality occurs regardless of the client. Anywhere you want a Script Trigger to fire, it has to be purposely attached to that layout or an object on that layout. Manage Database features are schema level while triggers are layout level. I always use an Auto-Enter, Validation calculation or other feature before trying a Script Trigger. Triggers are not a substitute for good programming skills. The abuse of this power of Script Triggers is my concern. With the power of FileMaker scripting firing behind the scenes based on events, often in combination with the calculation engine, a whole new world of programming flexibility not possible with single purpose features alone is open. There is no doubt amazing features can be created using Script Triggers. The ability to define a script to execute based on a defined event fills so many gaps, their power can never be underestimated. Triggers augment existing features like auto-enter and validation as well as introduce completely new functionality not available through button driven scripting alone. Script Triggers are one of the most fascinating features in FileMaker. The Philosophy of FileMaker recommends PCI! Here are the folks I think need to be recognized for their effort in shaping the early FileMaker (in no particular order):
Hall of Fame I started working with FileMaker 25 years ago and a lot has changed. In the case of a locked file, global Container fields will act like regular fields and not allow modification.
However, Container global fields behaves differently than the rest because they does not store data in memory. The values you enter into the global fields will be set back to the default upon closing but that still allows you to control the environment in FileMaker through the use of global fields. While regular fields cannot be modified, global fields can. This occurs automatically when a FileMaker file is stored on a CD or other read-only media. Global Fields When you lock a FileMaker file manually, it prevents changes being made to the file. Email John Mark Osborne or call John Mark at (909) 393-4664 to find out more about this service.
