With Brazos UI v3.14 or later, when running a coach from a Process Center environment you might receive the error "Resource Bundle Group with name BrazosResources is not attached." This is due to an IBM BPM product bug. This bug was exposed in Brazos UI v3.14 and later due to the Internationalization and Localization features that were delivered in that release.
The best way to resolve this issue is to install the appropriate fix from IBM.
