Executed when the listGrid receives a 'doubleClick' event on an enabled, non-separator record. The default
implementation does nothing -- override to perform some action when any record or field is double clicked.
A record
event handler can be specified either as a function to execute, or as a string of script to evaluate. If the handler is
defined as a string of script, all the parameters below will be available as variables for use in the script.
To do
something specific if a particular field is double clicked, add a recordDoubleClick method or string of script to that
field (same parameters) when you're setting up the list.
Notes: - This will not be called if the click
is below the last item of the list.
- This method is called from the default implementation of
ListGrid.rowDoubleClick(), so if that method is overridden
this method may not be fired.
