[opencms-dev] Script errors in with Firefox 3.5 / Opencms 7.0.5

What you describe sounds like some sort of race condition to me.

FF3.5 has changed the way how parsing interacts with javascript (called speculative parsing): HTML parsing does not block anymore, while Javascript files are loaded and then later, things like document.write(...) are patched into already parsed DOM tree.


But the script error that I get is "subnode is undefined":

  function getNodeIdByName(nodeName) { 
  ....
     for (i=0; i<childs.length; i++) {
         subnode = tree.nodes[childs[i]];
         var subname = result + subnode.name; 


Having subnode be undefined there is rather weird.
Both tree.nods and childs contain proper data. For entries in childs, there seems to be a corresponding entry in tree.nodes. And all entries in tree.nodes have a name property. So I really don't know what is wrong there. It all looks right

Sadly, the Javascript debugger of Firebug also seems to have a few issues in Firefox 3.5 right now, so some things behave a little strange (the source code location, where the degugger is at, is not shown properly, when stopping at a break point). 

But the opencms-Javascript seems to be fine and the data also seems to be right, too.

Weird indeed :(
