Hello
Try moving the setCenter to after the selection and skip the repaint.
The setCenter will trigger a projectionChange event which should cause a
repaint.

> In this example, the found shape borders are hilighted by a thick yellow-gold line. But if I uncomment the call to setCenter, the map gets centered properly, but the shape does not get hilighted. MapBean::setCenter is just a convienence for Proj::setCenter, so I don't know why this would affect the abiloty to hilight the OMGraphic.
