There are many ways to show validation error, some of them is about using some kind of tooltip. When using qtip we get issues, it's likely not used and tested often ->!/api/Ext.layout.component.field.Field-property-qtip

  1. When the tooltip disappear the focus on the field is lost, so if a user is typing some of his keystrokes may be truncated.
  2. If validation start to pass, the tooltip showing an error may still show for another 4 seconds! It should disappear right away.
