Hi there,

I've got a temp table called "TempShoppingList" that's being shown to the user in a new List page. I want to be able to perform an action on items that have been selected in that list. My current action looks like:

action(RaisePO)
            {
                Caption = 'Raise PO';
                Image = "Import";
                Promoted = true;
                PromotedCategory = Process;
                ApplicationArea = All;

                trigger OnAction();
                var
                    Line: Record "TempShoppingList"; // this is the page source table
                begin
                    CurrPage.SetSelectionFilter(Line);

                    if Line.FindSet() then
                        // codeunit.DoThing(Line)
                    else
                        Message('None selected');
                    exit;
                end;
            }

However, regardless of what is selected in the UI - the message stating 'None selected' always shows. I've managed to get the above working for normal out of the box tables, but not with tempoary tables. Is there anything I'm missing? Thanks in advance

Ah, that makes sense. Copying works great, thanks!

Because the temporary table on the page (rec) and the temporary table on the action (Line) are two different variables.

Try using copy first.

Line.Copy(Rec,true);

CurrPage.SetSelectionFilter(Line);

if Line.FindSet() then
