ListGrid.fetchData() fires 2 Fetches

[alan.hayes]

Hi,

I have a ListGrid which is bound to a remote datasource.
It has:
datapagesize = 10.

The properties sent to the server (via the fetchData method) are:
startRow = 0
endRow = 10

The properties returned to the grid are:
startRow = 0
endrow = 2
totalRows = 2

The problem is the fetch is fired 2 times instead of just once. I suspect it's because of these settings, however I can't see where/how.

However I am sure my properties are correct and it is still happening. I've checked everything else and can't figure out why the fetch is firing twice. My grid code follows:

setWidth100();
setHeight100();
setMargin(0);
setShowRecordComponents(true);
setShowRecordComponentsByCell(true);
setDataSource(ds); //a typical DataSource
setDataPageSize(10);
setFields(fields...);
fetchData();

Thanks,
Alan

I think I fixed this.

The endRow I was using was the total number of records returned. I subtracted one from it and it seems to have fixed it.

So for a grid with 5 rows, the correct values to set would be:

startRow = 0
endRow = 4
totalRows = 5

Is that correct?
