Problem description

Please, also check issue #361

Let's say you do not add a remote URL on the box and then you click again on the ADD button, upload a file and select a CSV. The message on the screen ("Failed to open the project....) never disappears and the user is not able to see the table on the left menu.

Steps to reproduce it

• Open the ODE.
• Click on ADD Remote file.
• Click on ADD (without entering a URL).
• Click on ADD, again.
• Select a CSV

Suggested solution

Apply solution suggested for issue #361 (do not display the message, force the user to enter an URL).
