    Exclamation JList Update and Clear... Up for a challenge? Lol (Help)

    [Java]annoying - Pastebin.com

    -

    I have no idea.. whats wrong with it.. It loads all records from text file into the jList1... with the ListModel.. but then when it comes to updating problems appeared.. the first one: when it adds to the ArrayList.. it goes to the first line? have no idea why even though I pass it an index - and the jList won't update or clear at all.

    Can someone please see what the hell is wrong with this code I just did? lol
