[Zope3-dev] Correction to rotterdam/xmltree.js

[Dave Harris]

Working with the latest CVS code, I continually get javascript runtime 
errors
whenever I select Manage Process or any of the buttons on the Manage Process 
page.
The error is simply: Object required. And points to

            items = xmlDomElem.childNodes;

in function getCollectionChildNodes(xmlDomElem)

I traced the code back into rotterdam/xmltree.js (there just has to be a 
better way to
do that)

The following change (rightly or wrongly) eliminates the runtime errors:

-       var items = xmlDomElem.childNodes;
-       var numitems = items.length;
        var currentItem;

        var currentItem;
+       var items;
+       var numitems;
+       if (xmlDomElem) {
+           items = xmlDomElem.childNodes;
+           numitems = items.length;
+       }
