Obscure Multiple Window Issue

Note: Thank you to Colleen Hammersley for bringing this issue to my attention, and to Howard Schlossberg for proposing a clever and elegant work around that addresses the issue on the Windows platform. (We’ll also look at another fix that works cross-platform.)

Today we’re going to explore a windowing behavior change that was introduced in FileMaker 12. If your solutions display multiple on-screen windows, then you may at some point find yourself facing this issue.


The problem manifests in different ways on the Windows vs. Mac platforms; we’re going to start out by looking at what happens in FMP/Win via the Window Focus, v1 demo.

Wim Decorte’s FM 12 Trigger Reference

The other day I had a question about some nuance involving script triggers. The details of that particular question aren’t important, but I recalled that when script triggers were first introduced, Wim Decorte had produced a detailed, color-coded reference.

I wondered if he had updated it for FM 12, and it turns out that he has, and with his permission I am sharing it here. There are actually two files in today’s download (Wim Decorte FM 12 Trigger Reference): the four page PDF reference, and a FM 12 file demonstrating the firing order of the various triggers.

There is a wealth of information to be gleaned from these two files, and I encourage you to download them and check them out. And of course if you find any mistakes or have any trigger-related observations to share, I hope you’ll post a comment here.

Note: even if you are sticking with FM 10 or FM 11 for the time being, if you use script triggers, the PDF in today’s download contains much that you will find relevant (hence my categorization of this post as “Version: FM 10 or later”).
