You could create a dynamic Forward, and append a query string. Just be
sure to create a new ActionForward for this.
Or, you can create the ActionForm for the okDialog yourself. Here's a
method you could put in a base Action, and use it to create ActionForm
beans for other ActionMappings.
/**
* Return an instance of the ActionForm associated with the specified
* path, if any; otherwise return <code>null</code>.
* May be used to create an ActionForm for InvokeAction.
*
* @param name path of the Action using the ActionForm bean
*/
public ActionForm createActionForm(String path) {
ActionMapping mapping = findMapping(path);
String name = mapping.getName();
ActionForm form = null;
ActionFormBean formBean = findFormBean(name);
if (formBean != null) {
String className = null;
className = formBean.getType();
try {
Class clazz = Class.forName(className);
form = (ActionForm) clazz.newInstance();
} catch (Throwable t) {
form = null;
}
}
return form;
}
So, you would pass it the path you are about to forward to, set the
properties on the bean, and send it along.
If you do it this way, just be sure that the reset method doesn't whack
the properties you preset.
