Re: columnSortHandler on a Dynamic CellTable

In https://groups.google.com/forum/?start=&hl=en#!topic/google-web-toolkit/7CFHEhWUjQA[1-25-false]

I don't know what is "verbColumn" in my exemple.

In http://stackoverflow.com/questions/16146094/gwt-columnsorthandler-setcomparator-for-all-columns-in-a-loop-make-the-sorting

I try to do the same thing, but I don't know how can this example can works because k is not "final"!

My try:

ListHandler<List<String>> columnSortHandler = new 
ListHandler<List<String>>(rows);

for (int column = 0; column < arrListFilters.size(); column++) {
IndexedColumn IColumn= new IndexedColumn(column);
IColumn.setSortable(true);
table.addColumn(IColumn, arrListFilters.get(column));

columnSortHandler.setComparator(IColumn, new Comparator<List<String>>() {
public int compare(List<String> o1, List<String> o2) {
          if (o1 == o2) {
            return 0;
          }
          // Compare the column.
          if (o1 != null) {
            return (o2 != null) ? o1.get(column).compareTo(o2.get(column)) : 1;
          }
          return -1;
    }

I have an error, "column" is not final..."Cannot refer to a non-final variable column inside an inner class defined in a different method"

Thanks for your answer.

I didn't know what to do, so I test with the 0th entry. I know that it is not the solution. 

In your answer, columnIndex is my "i" I guess? I can't get it, it must be "final". 

I try to do that, but it doesn't work too:

i=0;
while(i<table.getColumnCount()){
final Column<List<String>, ?> column= table.getColumn(i);
columnSortHandler.setComparator(column,new Comparator<List<String>>() {
public int compare(List<String> o1,List<String> o2) {
if (o1 == o2) {
return 0;
}
if (o1 != null) {
return (o2 != null) ? o1.get(table.getColumnIndex(column)).compareTo(o2.get(table.getColumnIndex(column))) : 1;
}
return -1;

}
});
i=i+1;
}

Why do you always compare the 0th entry? Shouldn't it match the column the comparator is responsible for, e.g. o1.get(columnIndex).compareTo(o2.get(columnIndex))?
