Hello,
We are using an async dataprovider in our celltable, and we have had
some problemt gettting the sorting to work.
In the OnRangeChanged method, we implement sorting this way:
if (sortList.get(0).getColumn().equals(costManagementNameColumn)) {
Collections.sort(effectConfigurationCache, new
Comparator<EffectConfiguration>() {
public int compare(EffectConfiguration o1, EffectConfiguration
o2) {
if (o1 == o2) {
return 0;
}
// Compare the cost management name columns.
int diff = -1;
if (o1 != null) {
diff = (o2 != null) ?
o1.getCostManagementName().compareTo(o2.getCostManagementName()) : 1;
}
return sortList.get(0).isAscending() ? diff : -diff;
}
});
} else if (sortList.get(0).getColumn().equals(orgUnitNameColumn)) {
Collections.sort(effectConfigurationCache, new
Comparator<EffectConfiguration>() {
public int compare(EffectConfiguration o1, EffectConfiguration
o2) {
.....
.....
}
});
} else if (sortList.get(0).getColumn().equals(effectTypeNameColumn)) {
Collections.sort(effectConfigurationCache, new
Comparator<EffectConfiguration>() {
public int compare(EffectConfiguration o1, EffectConfiguration
o2) {
......
.....
}
});
} else if (sortList.get(0).getColumn().equals(maximumThresholdColumn))
{
Collections.sort(effectConfigurationCache, new
Comparator<EffectConfiguration>() {
public int compare(EffectConfiguration o1, EffectConfiguration
o2) {
......
.....
}
});
}
This seems to be quite cumbersome !
Can this be done more elegantly?
Previously we used the ListDataProvider, and here sorting is
implemented directly on the ListHandler by setting a comparator for
each column, wich we think is a elegant way to do it!
