Bug in xLoadtree, Sascha Hofmann, February 13, 2002

Subject: Bug in xLoadtree From: Sascha Hofmann Date: February 13, 2002

Hi,

When removing the last "WebFXTreeItem" from a "WebFXTree" a javascript error occurs. The plus- and minus-icons thar are set on removal are only available for the "WebFXTreeItems" and not for a "WebFXTree".

I've channged the code to allow manipulation of plus- and minus-icons only if the parentNode has a parentNode. In other words if it is not the root.

<code>

WebFXTreeItem.prototype.remove = function() {

...

  if ( this.parentNode.parentNode )
  { iconSrc = document.getElementById(prevSibling.id + '-plus').src;
   iconSrc = iconSrc.replace('minus', '').replace('plus', '');
   document.getElementById(prevSibling.id + '-plus').src = iconSrc;
  }

...

</code>
