An empty string "" should be an acceptable key name

[GoogleCodeExporter]

What new or enhanced feature are you proposing?
Currently, setting a key name to "" results in a serial key being assigned by 
dynatree, as if the key were null.  I would like to see "" treated as a valid 
string, therefore a valid key.

What goal would this enhancement help you achieve?
I was trying to use fully-qualified path names as my keys.  For convenience of 
string joining with a separator (e.g. "/"), I wanted to use an empty string "" 
for the key of my root.  So, if the root's child node was named "child1", its 
key would be: "" + /" + "child1", therefore "/child1".

I thought that this should also be fixed with issue 420
Did you try witj the lates code from the trunk?

This is the patch for 420:

    // if( !data.key ){
    if( data.key == null ){ // test for null OR undefined (issue 420)
        data.key = "_" + tree._nodeCount++;
    }else{
        data.key = "" + data.key;
    }
