Conversion Error setting value '[1, 2, 3]' for 'null Converter'

843844Aug 14 2008 — edited Jan 18 2010
Any input into this conversion error for an arraylist?

" "recipientIdList": " Conversion Error setting value '[1, 2, 3]' for 'null Converter'. " "recipientIdList": " Conversion Error setting value '[1, 2, 3]' for 'null Converter'.

<h:inputHidden id="recipientIdList" value="#{emailBean.recipientIdList.value}" />
private ArrayList recipientIdList;
recipientIdList is an arraylist of Long objects.
