I tried catching exceptions and none were thrown.  My implementation is
pretty simple, as in this example, which adds a listener to a dialog
containing a choice menu.  If "voxel" is selected, the numeric field is
greyed out (setEnabled(false)) by the dialogItemChanged method.

http://github.com/mdoube/BoneJ/blob/master/src/org/doube/bonej/VolumeFraction.java

If I include the DialogListener, options are not recorded.  Commenting
out gd.addDialogListener restores option recordability (tested on IJ
1.43u and 1.44a8).

Could this be a difference between ItemListeners (which I haven't yet
used) and DialogListeners (which I currently use)?
