Paging in a rowset

Question

I have a database driven search page,which searchs
rowsets by a variable from a textField.
I have in the tableLayout paging enabled with for
rows.
If a search a new rowset and iI get 6 rows, in the starting page I have 4 rows, thats ok. But .If a click now the next button the page shows always the first
four rows.Why ?
Thanks

Hi Peter,
First make sure you have a message list component to show any validation/converter error msgs...
Assuming that is not the problem, I'm thinking you might not want to re-execute the model every time the page is rendered (including "callbacks" like when you click the 'next' button). See how this is done in the App Model (using properties stored in the essentially).
So see the app model for how it handles this - but essentially it store something in the session which indicates each time you first navigate to the the page.
Then wrap is all ithe data table model methods in your constructor in an if statement so that if the session property is set (indicating the constructor was called during navigation) you call the data table model methods... otherwise you assume it's a callback and the dataTableModel is already setup so you skip it..
hope that makes sense... if not please see the appmodel :)
