Hello,

Here is the problem I am stumbling with for a couple of days. I have a tree view (a one2many field) inside a form view for which the records are created/updated/deleted depending on a field that sits inside the form view. I am using a combination of @api.onchange and falgs (1,ID), (2,ID) to modifiy the tree view content. Everything's fine except one case : I cannot delete lines in the tree view that were created from {0,0, {...}) and if the main record is not saved. The reason is that the created record gets an ID when the whole thing is saved.

I did add the ID field of the one2many records in the treeview, for newly created (and not saved records), the ID is empty. Thus I do not see a way to delete them, the command that comes out of iterating over the list of ids is (2, False), ie delete a record for which there is no Id, this does not work.
What is the way (if any) to delete records created with (0,0,{...}) and not saved to database yet ?
