defininf of Current Document throws a js error for new user

[GoogleCodeExporter]

1. log in  as absolutely new user 
2. notice javascript errors. 

The reason: new user has no any document records in database so new document 
should be created for him. The form where doc name should be entered is shown 
to user. Сreation of doc happens when user clicks save button. But before this 
initWorkspace() method finishes its work by setting active doc, which is null  
at this point.

so we need to write some logic to make all this work one after another but not 
simultaneously
