How do you remove the root node? Please try the code below.

Code:

var roots = $('#tt').tree('getRoots');
for(var i=0; i<roots.length; i++){
	$('#tt').tree('remove',roots[i].target);
}

I tried, but the bug wasn't solved. I think, maybe when I removed all roots of tree, then the tree is empty , so occur the bug '0.target is null or...' , is it right? If I'm right, how can I do ? I'v paste my codes to General Discussion, you can write a 'remove' function to try.
