The exception is corrupting the json formatted response so when
Query.php returns there is a (likely suppressed) javascript error that
prevents Fusion from processing the selection and hence other widgets
from responding to it to load the selection.
Mike, we should be able to reproduce this with some of Jason's data.
Cheers
Paul
