Tree refreshItem() not working

[mshaffer]

I am loading a tree hierarchy via an XML fetch to my server. When the user does something to alter the tree, I want to refresh the tree by calling:

tree.refreshItem(‘xxx’);

where ‘xxx’ is the id for the main root of the tree.

When I invoke this, I get a javascript exception on this line:
TypeError: str.indexOf is not a function

Note: I have tried with no parameters with the same result.
tree.refreshItem()

What am I doing wrong (besides choosing the wrong career )?

refreshItem works only in dynamic trees and uses script that is defined in the setXMLAutoLoading method as xml source. Here is the sample

Another approach to reload tree is:

tree.deleteChildItems(0);
tree.loadXML(url);

Thank you, the alternate approached worked
