Hi all,
I'm re-posting this question. Hopefully more clear than before.
I've been struggling much with a problem for so long and fail to get
it to work. I don't know where I go wrong but below is my code.
I've got 2 tableviews populated by this file, data.plist, with
bindings. When I push a button it loads the data in the tableviews.
Selecting a row from the first tableview loads the second and
immediately updates the webview with the corresponding html-file. And
that annoys me.
There's something about notification, tableSelectionChanged, and
NSTableViewSelectionDidChangeSelection. But I'm unsure how it works.
I've been reading up on the tableview class reference, but still...
I'd like so very much ...
a) ... to load the data in the tableviews one tableview at a time
or
b) ... update the webview when a row is selected in the second
tableview, i.e. the final tableview.
I appreciate any help that can be provided. /Philip :-)

// Ensures that the first tableview does not scroll out
of view
[tableView1 scrollRowToVisible:[tableView1
selectedRow]];
}
-(void) tableSelectionChanged:(NSNotification*)aNote {
NSTableView* tableThatJustChanged = [aNote object];
if ( tableView1 == tableThatJustChanged ) {
// Get the selection of the publicationsController
} else if ( tableView2 == tableThatJustChanged ) {
// middle
}
}
