The current content of the RemoteField bean is nothing more than an Id and a Name.
But the result of a call to the service 'getCustomFields' (retrieving all Custom fields) should contain more info than just the id and the name.
Especially with CustomField which type is Cascading Select and has Custom Field Options it is important to have at least the Custom Field options, because such a Custom Field filled in an issue will return ID's as its CustomFieldValues and I cannot relate these ID's to the selected options.

So adding String type and String[ ][ ] options to the bean and String get/setType and String[ ][ ] get/setOptions methods should be done.
