For the edit case, the trick was to forward to an Action that created a form bean prepopulated with the values from the database object, and then forward to the page. Craig

Joe, Ted, Your proposed solutions worked well. Thanks.

If a hidden variable (I called it 'process') had been set, then the action would validate the input, then store the new info into the database.

Hogan, John wrote: Joe, Ted, Your proposed solutions worked well. Thanks. Here's a simple trick for returning a blank ActionForm for new data-entry. Define a generic Input action, that does nothing but return (new ActionForward(mapping.getInput())); Then whenever you need to get a blank ActionForm, of any type, just create a mapping to the generic Action, specifying a different input property: action path=/bid/Input type=org.wxxi.gavel.lib.Input name=bidForm scope=request validate=false input=/WEB-INF/jsp/bid/Form.jsp /action Or, action path=/donor/Input type=org.wxxi.gavel.lib.Input name=donorForm scope=request validate=false input=/WEB-INF/jsp/donor/Form.jsp /action This way you don't have to check for an add request for each form type. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 737-3463. -- http://www.husted.com/about/struts/

Re: ActionForm/Action with edit mode
If I understand the question, all you have to do is change the form's action to insert or update as the case may be. A good way to do this is to have a task parameter that you would pass to a single action designed to handle both cases. You can do this dymamically using (where key=0 means we're inserting a new record). logic:equal name=myForm property=key value=0 input type=hidden name=task value=insert /logic:equal logic:notEqual name=myForm property=key value=0 input type=hidden name=task value=update /logic:notEqual For an update, visit an Action first, select the record, populate the form, and forward to input.
