copy row to create screen with entity having composition relation with another entity

Support
#1

Hi Team,

I have to implement the copy mechanism of entity which is having composition relationship with other entity. For example Invoice entity having Invoice lines.

I am able to go thru sample project (copy.zip) there it has mentioned to user openEdition() method.

when i tried the same way, I am losing the Invoice Lines in invoice object.

Please suggest me how can i save copied entity which contains the relationship.

Regards,
Nagendra.

Thanks for sending the test code.
Solution is simple: you should copy InvoiceLine instances as well:

public class InvoiceBrowse extends AbstractLookup {

    @Inject
    private GroupTable<Invoice> invoicesTable;
    @Inject
    private GroupDatasource<Invoice, UUID> invoicesDs;
    @Inject
    private Metadata metadata;

    public void onCopyBtnClick() {
        Invoice invoice = invoicesTable.getSingleSelected();
        if (invoice != null) {

            Invoice copyInvoice = metadata.create(Invoice.class);
            copyInvoice.setDate(invoice.getDate());
            copyInvoice.setDescription(invoice.getDescription());
            copyInvoice.setNumber(invoice.getNumber());

            copyInvoice.setInvoicelines(new HashSet<>());
            for (InvoiceLine invoiceLine : invoice.getInvoicelines()) {
                InvoiceLine copyLine = metadata.create(InvoiceLine.class);
                copyLine.setInvoice(copyInvoice);
                copyLine.setAmount(invoiceLine.getAmount());
                copyLine.setEmployee(invoiceLine.getEmployee());
                copyLine.setProjectName(invoiceLine.getProjectName());
                copyInvoice.getInvoicelines().add(copyLine);
            }
            openEditor(copyInvoice, WindowManager.OpenType.THIS_TAB).addCloseWithCommitListener(() -> invoicesDs.refresh());
        }
    }
}
