1) how can I set Cursor to 0 possition without using Caret or Focus wrapped into invokeLater() (confortly can be solved by using @camickr <a href="http://tips4java.wordpress.com/2010/02/21/formatted-text-field-tips/" rel="nofollow noreferrer">Formatted Text Field Tips</a>), is there somebody who knows another way

sometimes (by raising Focus by TAB from keyboard), reset doesn't works and on focusLost (empty field) Formatter returns/reincarnated chars or String back (last know before setText("")
,
Note: know code or following code
, about how to reset Formatter from OTN, but their terrible search rulles ...., only code (question or answer by Jeanette???)
