Folks,
Just following up on what turned to be my own blunder. Using
ListDataProvider doesn't work when the CellTable is created using pageSize
= 0.
super(0, resources, keyProvider);
It still works when using setRowCount(); setRowData();.
So I fixed it for the time being by setting a meaningfully large pageSize.
Here is the question: would it make sense to add a bit more to the Javadoc
for pageSize. Or maybe checking for 0 and throwing IllegalArgumentException?
