Drag and drop vm file from outside project doesn't work

[GoogleCodeExporter]

Dragging and dropping a vm file from outside the project creates a screen with 
a blue line, and the 
text "ERROR" below it. Also, the status line contains '?' for column and line 
number.

even simpler, I guess (untested) replacing your VelocityDocumentProvider class 
with
the following code fragment would solve this issue:

public class VelocityDocumentProvider extends TextFileDocumentProvider
{
    @Override
    public void connect(Object element) throws CoreException {
        super.connect(element);
        IDocument document = getDocument(element);
        if (document != null) {
            if (document.getDocumentPartitioner() == null) {
                IDocumentPartitioner partitioner = new FastPartitioner(new
VelocityPartitionScanner(), VelocityPartitionScanner.TYPES);
                partitioner.connect(document);
                document.setDocumentPartitioner(partitioner);
            }
        }
    }
}
