Hi All,
Is there a reason why the ERXBatchingDisplayGroup wouldn't increment the
_rowCount variable when you call insertObjectAtIndex?
If you have a BDG that has a rowCount() that is an exact multiple (including 0)
of the numberOfObjectsPerBatch() and you insert a new object, the rowCount()
doesn't change and therefore neither will the batchCount(). Since the
batchCount() didn't increase, any objects that would have been displayed in the
last (new) batch are not displayed, and won't be until you refetch, even if you
sort.
Overriding insertObjectAtIndex in ERXBatchingDisplayGroup like this:
@Override
public void insertObjectAtIndex(Object createObject, int newIndex) {
super.insertObjectAtIndex(createObject,
newIndex);
setRowCount(_rowCount + 1);
}
and then modifying setRowCount to also call updateBatchCount()
public void setRowCount(int rowCount) {
_rowCount = rowCount;
updateBatchCount();
}
will fix the problem I'm having, but I don't know if I'm missing some other
problem that this will cause.
If this is the correct change to make, then we should also override
deleteObjectAtIndex as that will change the rowCount as well.
@Override
public boolean deleteObjectAtIndex(int anIndex) {
boolean objectDeleted = super.deleteObjectAtIndex(anIndex);
if (objectDeleted) {
setRowCount(_rowCount - 1);
}
return objectDeleted;
}
Does anyone have any input?
If not, I'm going to create a Jira ticket to patch ERXBatchingDisplayGroup.
Dave
