I receive this error after executing a query and binding the result EntityQuery to the @Out parameter.  Not sure what I am doing wrong. Any insight would be appreciated. Thanks!


Class Code Snippet:
===================
@Out(required=false)
protected EntityQuery<AccountStock> openPositions;

viewOpenPositions Method:
=========================
openPositions = new EntityQuery<AccountStock>();
                        openPositions.setEjbql("select accountStock from AccountStock accountStock where accountStock.accountId = #{accountHome.getInstance().getAccountId()} and sellDate is NULL ");
                        openPositions.setOrderColumn("purchaseDate");
                        openPositions.setOrderDirection("ASC");
                        openPositions.getResultList();
