User comments: Start today's build on a fresh userdir.  Install the CDC toolkit.  Create a new CDC Application from
template.  The following exception is thrown, even though the file in the stack trace exists and is opened in the editor.

Perhaps some race condition in Data Loaders, i.e. recognized first by Java DL then as form?

Comment 6 _ tboudreau 2009-02-25 17:54:06 UTC 
Anybody looking into this?  This looks like some sort of race condition - the FileObject *is* and the DataObject for it
is returned from the new project wizard, but then the code that tries to open it sees an invalid DataObject for it.  But
the file does exist.

Looking at the code path from a DataObject's constructor in DataObjectPool and DataObjectPool.Item, I wonder if this
(from DataObjectPool.Item) could be the culprit - this is the code that is deciding the DataObject is invalid:
       public boolean isValid () {
            if (getPOOL().map.get (primaryFile) == this) {
                return primaryFile.isValid();
            } else {
                return false;
            }
        }


Possibilities:  Two threads simultaneously register the same DataObject (i.e. enter the constructor for a DO for the
same FileObject at the same time - it is probably possible without an exception if the timing is right).  Whichever one
gets there first could causes the if-test to fail for the other to fail.

My point here is that the primary file is valid, so the problem is probably in the registration code (which has caused
problems in the distant past, since it runs in the superclass constructor, and registers the DO before the subclass
constructor has completed).  In other words, there is already another DataObjectPool.Item registered for this FileObject.
