Hi Colin,

This is likely a bug in the 2.0 version.  We will look into it.  Thanks for reporting it,

In VisTrails 1.7 when the user moved one of these ports down to change the value the default value was displayed in the input box.  In 2.0 the data entry box is blank and the user doesn't know what the default value was/is.  Is there a new or better means of specifying a default so it's visible to a user?
