Sure. Here is what happens in the method targeted by the button. From
the tableview ( = sender) it gets the first column, from that it gets
the array controller behind the column, from that it gets the
selection and finally it gets the string I am after. All of this is in
a core data app, and I am not using a data source per se. 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.
//get 1st column in sender:
NSTableColumn *tableColumn = [[sender tableColumns] objectAtIndex:0];
// get bound-to array controller
NSArrayController *arrayController = [[tableColumn
infoForBinding:@"value"] valueForKey:@"NSObservedObject"];
// get selected object's URL:
NSString *selectedPersonPage = [[arrayController selection]
valueForKey:@"URLFragment"];
NSLog(@"selectedPersonPage: %@", selectedPersonPage);
Thanks again,
Rainer

Hello all,
I have a table view with a column that holds a button cell. When
the user clicks the button I need to open a web browser with an URL
that is stored in the object represented by the table view's row.
All of this is in a Core Data app.
When the button is clicked in a row that is already selected
everything works as expected.
When the user clicks a button in a row that is currently not
selected, then I get the URL for the row that's in the process of
being de-selected, because the method targeted by the button runs
before the selection has changed to the new row.
What can I do about this?
Can we see the code in the method targeted by the button? It is good
to show some code when asking for help.
Although it might not be necessary--I suspect you are using -
selectedRow instead of -clickedRow to get the row the user clicked.
Try -clickedRow.
