I must admit some ignorance of core data apps, but maybe that won't matter much. From what you said, sender is the tableview, so that is the same thing I would expect in a non-core-data app that I have more experience with. You concern me with this statement of yours: > The problem seems to be the timing of it all, rather than how the method > works, because when the selection doesn't change in the button click, > everything is fine. It's not that everything is fine. It's that in your test case (where the selected row equals the clicked row), the thing that you are looking at (the selected row) just happens to be the same as what you want (the clicked row). So if you will accept that what you want is the clicked row, and you don't really care about the selected row(s), see what happens if you use [sender clickedRow] to get the clicked row, then from there to get your URL. Maybe -clickedColumn can help you too (your code has lost me a bit so I can't say for sure) Hopefully my ignorance of core data isn't wasting your time. If it wasn't a holiday weekend (or even week) here in the states, I'd probably lurk this one out._______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
