Found some interesting code comments today:

try {
params.put("bed", propertyInfo.getAttributes().getBedrooms().toString());
} catch (Exception eignore) {
/* who cares */
}
try {
params.put("bath", propertyInfo.getAttributes().getBathrooms().toString());
} catch (Exception eignore) {
/* not me */
}
try {
params.put("price", propertyInfo.getPostingInfo().getForSalePrice().toString());
} catch (Exception eignore) {
/* really it's fine if these don't get set*/
}
