I have a datatable that shows different sets of data basing on the state of ajax components. For each row of this table an operation can be done, by clicking button. That moves to another page. Now I want to go back from that page to the one with table, but it should be filled with the data they were before. To do this I need to restore state of ajaxed componets, like dropdowns. How can it be done in the simplest way?
