Scrolling behavior on text pane

Hello,

how do I achieve that a JScrollPane which has a JTextPane as viewport,
will scroll automatically along with the added text at the bottom? The
latest text entries shall be readable at all times!

TIA
Karsten

setCaretPosition to the end of the text.

myPane.setCaretPosition(myPane.getText.length());

OK I found it. However the solution here was to use

setCaretPosition(getDocument().getLength());

instead.

setCaretPosition(getText().length()); //IllegalArgumentException (bad
position)

Don't know why though...

My theory is that because I'm using a styled document and the caret
likely won't care about text pane styles/contents that there's some
offsetting involved... *shrug*
