Dear Albartell,
I have also the same problem : I can not load the full data set into my table.
Do you found any solution to your problem ? I would be interested to have it !

Marc

Dear Andrew,

Re: DataScroller - current page?

Besides the fact you are using a way outdated version, there should be
no reason you can't just show part of the results, I do it all the
time in our application. You just have to build a custom DataModel
class. Just extend DataModel.
Tips:
public int getRowCount:
Return the total number of rows, not the number you have loaded
public Object getRowData:
Return from your local subset of results, the current data table row
index minus the "Start at". Where "start at" is the current data model
page (if on page 5 and showing 20 rows, start at would be 100)
public boolean isRowAvailable:
Return if the row index is >= the start at and the row index is less
than the current number of items loaded.
You can load the data when the "setRowIndex" is called by the renderer.
You may need to extend the data table to get the notification when the
"first" attribute is set if you don't upgrade to the current version
of 1.1.6 tomahawk. The reason is that the old HtmlDataScroller in the
setFirst method only set the UIData's local variable, the new code
actually uses the ValueBinding to set the first (and thus you can
update your DataModel's start at property)
