Scroll grouped listview, crash RRS feed

  • Question

  • Hi All,

    I have a grouped listview, if there are much items, it will crash while scroll it many times.

     the error thrown from function getClassName, I find that the "e" is null, so e.className failed.

    functiongetClassName(e){

    varname = e.className || "";

    .....

    Get the call stack as below, anyone can help this? Thanks.

  • I changed our design, but it appears to have been caused when I updated a listviews indexOfFirstVisible attribute. My guess is it wasn't rendered by the time I was trying to scroll to that position.  Good Luck.
