root.children is null or not an object

System

I haven't figured out the pattern exactly, but sometimes when I create a new DCR or open an existing one I get the error root.children is null or not an object. The DCTs have a lot of FormAPI, but it doesn't look like it's custom code accessing this variable - it looks like an anonymous function (source not visible) calls refreshTree() which calls refreshNodes (in datacapture_nav_tree.html), which accesses root.children. I think there may be some issue with callServer - my CGI is trying to repopulate drop-downs, etc. while Interwoven is trying to refresh the page and there is some kind of conflict. I have found a way to avoid callServer in most cases but in this case I can't. Is there a fix for this? The problem is that once JavaScript crashes on this bug, the resf of my FormAPI does not execute. Other times when I open the DCT I get no error and the form works fine, so I am assuming it's the good ol' async callServer interacting with what is otherwise assumed to be a synchronous environment.
