title: How to save the changes made in the NSTableView back to the source array used for the populating this table?
body: <p>I have view based <code>NSTableView</code> with two columns. Instead of default <code>NSTextField</code>s I have inserted <code>NSTextView</code>s. For populating the table I am using the array of tuples of two strings. After I change the text in the <code>NSTextView</code>s I want to save back all changes from all rows and columns to the source array by clicking the button. I need to know each row and <code>NSTextView</code>s to get the strings for the array. How to do this ? First problem is that I cannot even make the tags for particular <code>NSTextView</code>s, they are inactive in Attributes Inspector  (for <code>NSTextField</code>s tags are active). </p>
