#729 Drag Copy grid example bug

[Anonymous]

Originally created by: had...@digitech.cz

In showcase, there is Drag Copy grid example, with this code:

ListGridField countryCodeField2 = new ListGridField("countryCode", "Flag", 50); 
        countryCodeField.setAlign(Alignment.CENTER); 
        countryCodeField.setType(ListGridFieldType.IMAGE); 
        countryCodeField.setImageURLPrefix("flags/16/"); 
        countryCodeField.setImageURLSuffix(".png"); 
        ListGridField nameField2 = new ListGridField("countryName", "Country"); 

These countryCodeField should be renamed to countryCodeField2, because countryCodeField was initialized already, few lines above.
