Hi Erik,
In most cases, focusing in the first control is what's best for users, but there are indeed cases, like the one you describe, where this isn't desirable. In cases like this, I'd recommend you use the oxf.fr.detail.initial-focus.*.* to disable this feature. And note that this propery allows you to disable setting the focus just for just a specific form or group of form, and keep it for other forms.

Alex
