Correctly resizing rows on view-based NSTableView

A view-based NSTableView with rows that have dynamic heights doesn't resize its rows when the table view size is changed. This is a problem when the row height is derived from the table view's width (think text blocks that fills a column and wraps thus extending the row size).

I've been trying to get NSTableView to resize its rows whenever it changed size but have experienced little success:

• If I resize only the visible rows by querying enumerateAvailableRowViewsUsingBlock:, some of the non-visible rows doesn't get resized and thus were shown with the old height when the user scrolls and reveal these rows.
• If I resize all rows it becomes noticeably slow when there are a lot of rows (about 1 second delay after each window resize for 1000 rows in my 1.8Ghz i7 MacBook Air).

Anybody can help?

This is where I detect the table view size change - in the table view's delegate:

- (void)tableViewColumnDidResize:(NSNotification *)aNotification
{
    NSTableView* aTableView = aNotification.object;
    if (aTableView == self.messagesView) {
        // coalesce all column resize notifications into one -- calls messagesViewDidResize: below

        NSNotification* repostNotification = [NSNotification notificationWithName:BSMessageViewDidResizeNotification object:self];
        [[NSNotificationQueue defaultQueue] enqueueNotification:repostNotification postingStyle:NSPostWhenIdle];
    }
}

Whereas the following is the handler of the notification posted above, where the visible rows get resized:

-(void)messagesViewDidResize:(NSNotification *)notification
{
    NSTableView* messagesView = self.messagesView;

    NSMutableIndexSet* visibleIndexes = [NSMutableIndexSet new];
    [messagesView enumerateAvailableRowViewsUsingBlock:^(NSTableRowView *rowView, NSInteger row) {
