Hi,
I need to do sorting on columns in a
datatable.
The table is bound to a list of beans.
The bean consists of some simple string variables
and some list variables.
I am implementing java.util.Comparator class to do
the sorting by using Collections.sort()
I am able to sort the simple columns but the
columns which display a list of data are not being sorted.
for example : column 1 shows list of names and
column 2 shows a list of tickets per name i.e it displays a list of
list.
Now, I am able to sort column 1 but not column
2.
Can anyone suggest to implement this?
My sorting code is like this :
GenericComparator gc = new GenericComparator(TrackingDisplayBean.class);gc.addCriteria(colValue); gc.setNullValueTop( false);gc.setDirection(orderBy); Collections.sort( this.display, gc);colValue is a variable defined in the bean "TrackingDisplayBean". If type of colValue is simple datatype like string or integer, its working fine. but when it is a list of say string, its not working. Any ideas? -Sunil |
