Description of problem:

1.) Change the value in the Data Center Name field from "Default" to something else, then restore it back to "Default". The warning text "Note: You must change the cluster name after changing the database name" does not go away, and the Next button remains disabled, until I do the same to the Cluster Name field.

2.) If instead I first change the Cluster Name field, then undo the change, the Next button remains disabled but there is no corresponding warning text.

In both of these cases, I would expect the warning text to disappear and the Next button to be enabled again.

3.) If I change either the Data Center Name or Cluster Name from "Default" to "Default " (trailing space), there is no warning text, but the Next button is disabled. Warning text only appears once I add a non-space character, e.g., "Default 1":

"must contain only 'A-Z', 'a-z', '0-9', '_' or '-' characters"

If spaces aren't allowed, then the warning text should be triggered as soon as one is entered.

4.) If I click on 2C. Hypervisors, then back on 2D. Configuration (or Back then Next) after entering bad values in the Data Center Name or Cluster Name fields, then the warning text disappears, and I can edit the field with no further warning until I click elsewhere or tab off of the field.

5.) Since the field is called "Data Center Name", would it make more sense for the warning text to refer to it as such instead of as "database name"?
