My action resembles: .... public class ApproveItemsAction extends ActionSupport { private Integer[] approved; private Integer[] itemsPresent; ... public void setApproved(Integer[] approved){ this.approved = approved; } public void setItemsPresent(Integer[] itemsPresent){ this.itemsPresent = itemsPresent; } } When some number of checkboxes are selected, then I get an array containing the ID values of the checked objects. This is correct. When NO checkboxes are selected, I get: No result defined for action bpf.labs.action.ApproveItemsAction and result input Which is not expected. My action never hits the execute method in this scenario. It never even hits 'setApproved' (it does if there are values checked. It does not if there are none). I expect setApproved be called with an empty array or just null. Either is acceptable -- Null being what I expect I'd PROBABLY see and an empty array being what I'd be HAPPY to see. Instead this situation just seems to confuse struts and 'input' is returned at what looks like the time the parameter interceptor is probably trying to handle the checkboxes. Is there a way to handle this? Having no checkboxes selected needs to be an acceptable form submission state for this action. My itemsPresent array must be null or an empty array.
Forwarding to 'input' usually means a validation error occurred. Do you have any validation configured for this action?
