(Also see: http://www.silverstripe.org/general-questions/show/15576; same problem)
I have an ArticleHolder/ArticleContent DataObject which contains certain data. Also I have an InvoicePersonal, InvoiceHolder and InvoiceContent class, which respectively contain personal details, packages and package content. Last two both refer to the Article Dataobjects.
The relation between them are all one_to_many, so one InvoiceHolder contains many ArticleHolders, one InvoiceHolder contains many InvoiceContents which on turn contains one ArticleContent per row.
Now I can add all InvoiceHolder stuff, but than I get an popup where I can edit the InvoiceContent of an InvoiceHolder. This unfortunatelly does not show an Add-button.
I think I have to define a complex table field myself, based on the URL posted above, I only do not know exactly where or how. ny help for this will be appreceated.
Thanks in advance,
