I don’t know your needs, it might be that LazyList as it is is good enough for you.

Thank you for your reply,
I will send a search request to another module, with the parameters (filterContent, firstTransactionNumber, transactionsNumberPerPage) then it will contact the Database persistance and return the range of transactions that i want to show to the user, all these transactions will be inserted into a table.

Because i don’t have the Database interface, i should get the list of informations by another package.
So there is no SQL Query.
