Tooltips in backend administration forms

The fx:formRow component supports CSS-based tooltips that can be used for a short description of a form input field. To set a tooltip, you have to set the input label using the "labelKey" attribute, where labelKey identifies a message key containing the actual label. To set a tooltip, simply create a message key by appending ".tooltip" to the labelKey and set the tooltip message.

For example, consider the following input row:

<fx:formRow labelKey="QueryEditor.label.briefcase.name">
     (...)
 </fx:formRow>

You create a label including tooltip using these message resources:

QueryEditor.label.briefcase.name=Name
QueryEditor.label.briefcase.name.tooltip=Enter the name of the briefcase you want to create.
