Comment 7 for bug 479302

Jay, Anup, please excuse this late answer.

The patch you propose is good in that there is no more error in the client's stdout.
However there is a little problem remaining.

Please take the example module at lp:~numerigraphe/openobject-addons/bug479302, and reproduce the steps in comment #2 but don't save the record.
You'll notice that when you validate the popup and there are 6 empty lines, the client will remove 3 of them, and leaves the 3 others. In the main list view the column "elements" will show "(3)", and if double-click the row, the popup will show 3 empty lines.
If you then validate the popup again, 2 empty rows are removes but 1 still remains.

If you save the record however, all the empty lines are removed which is fine.

Could you please look into this mater ?
Thanks in advance,
Lionel.
