ListGrid advancedFieldPicker is unable to add fields where detail='true'

[bbruyn]

I sort of fell into the new advancedFieldPicker by accident, as did this guy. Nice feature, and we'd like to use it, but:

Fields having 'detail' attributes set to true are shown in the 'Available Fields' panel, can be selected and added to the 'Current Fields' panel, but the 'Save' action has no effect. The field is not added, nor is it in the 'Current Fields' list on subsequent attempts.

No output in the Developer Console.

Tested with 3.1.d20120807.

This has been fixed in the latest development stream. It should be in the next build (SC 8.3d/SGWT 3.1d).
