Well, here's what I do. 1) Have a private method (prepare??) in your action class which is responsible for populating all your Select boxes. This method is called from your main Action method.
2) Call the validate method from your Action class explictly, instead of setting "validate=true" in the struts-config file 3) After calling the validate, check the errors.size, if you have errors, just call the private method (prepare or whatever you call it and forward to your input page.
