Sorting of null incorrect
-------------------------
Key: DISPL-206
URL: http://jira.codehaus.org/browse/DISPL-206
Project: DisplayTag
Type: Bug
Components: Paging/Sorting
Versions: 1.0
Reporter: dcheng
Shouldn't nulls be less than any object which isn't null? When sorting
columns, null values appear at the top when sorting in descending order.
See rowsorter(lines 160-167):
else if (object1 == null && object2 != null)
{
returnValue = 1;
}
else if (object1 != null && object2 == null)
{
returnValue = -1;
}
If possible, could the return values be flipped around or an attribute added to
display:column to let user choose whether nulls should be greatest or the least.
Thanks,
David
