[Pharo-users] How to find the cursor position relative to its text for TextMorph or RubTextFieldArea

At first I thought that TextMorph>>cursor would return me the position of the cursor relative to its text so if I have a text like "hello" and cursor (that blinking thing) was at "o" it would return 6 but no, whatever position I try it returns always 1 . With rubric I found no way to do this either. Anyone has a clue, or to I need some kind of pharo dark magic ? Is this a bug , a feature or something in between ?
