    Exclamation Crash after update ul list items with navigation keys

    Hi

    I use the left and right keys to update a list items inside a UL list.
    I have the setNavigationEnabled = false.

    When the actual list have more items (li) than the next list and the selected item in the actual list is (n+1) or more (n= number of items in the next list) the WRT runtime crash whe I change the list using the left and right keys.

    left and right keys allow navigation changing selected item and I use the same keys for update the content.

    Example

    First list 4 items
    Second list 2 items

    The first list is displayed
    <ul>
    <li>item 1</li>
    <li>item 2</li>
    <li>item 3</li>
    <li>item 4</li>
    </ul>

    and the item 4 is highlighted

    press the right key, that trigger 2 things:

    -the WRT behavior that change the highlighted item from 4 to 3.
    -and the event that I trigger: update the list content, so now the list displayed is:

    <ul>
    <li>item 1</li>
    <li>item 2</li>
    </ul>

    Now, the list have 2 items, but the WRT try to select the third, since the third don´t exists, the WRT crash.

    any way to avoid that? (keeping the left and rigth keys) using non navigation keys don´t show this behavior.

    Re: Crash after update ul list items with navigation keys

    Hi pablopoo,

    I noticed some crashes in similar situations, where DOM elements are added or modified just after user actions. On which devices/firmware did you notice this behavior?
