Hi Martin. Let me re-word my question. I need all the data associated with a dataTable in my java code to do some stuff with it. If you somehow get hold of this dataTable object - it's not possible to get data out of it as all such methods are protected. BUT a dataScroller has a method - getUIData() - which gives the data on the "active" page. So if I associate a dummy scroller with our dataTable (also dummy - copy of original with rows=all data) (but hide it) having just 1 page, I have access to all data in dataTable (indirectly using dataScroller). This is the hack I was talking about.
Is it clearer? I wanna know if there is a better way to get all data associated with the table on java level? Why I wanna do this - or where am I headed - to get a custom scroller. Current data scroller gives a paginator in the following format: 1-100, 101-200, 201-300.. and so on. What I would like is value of a column (along which the table is sorted), for example: AAA-CAT, CAU-FAX, FBC-MPC... and so on. The advantage is that user sees immediately where the value lies in the paginator (and does not have to guess). To do this.. I need all the data in the dataTable on java level. Hope I was clearer????
