how can i access the getters and setters in of a DynaValidatorForm from within an action method?
when i had a own form class i could do the following in a action method: productForm = (MyOwnForm)form; productForm.setComboArrayList(comboArrayListWithBeans); with a dynamic form i cannot cast anymore or do i have to cast to a DynaValidatorForm? is it actually possible to do a cast or do i have to implement a ValidatorForm instead of using a DynaValidatorForm? thank you Pille wrote: > > Christopher Schultz wrote: >> Philippe, >> >> Pille wrote: >>> but after submitting the form with wrong input and returning >>> to the jsp-page i get the following exception: >>> javax.servlet.jsp.JspException: Cannot find bean under name countries at >>> org.apache.struts.taglib.html.OptionsTag.getIterator(OptionsTag.java:374) >>> after submitting the form with wrong parameters and returning to the >>> page the beans are gone. is there any possibility to set the beans with >>> request.setAttribute() again? >> You are encountering a common problem with a simple solution.
