I am having a problem trying to submit my JSP. It causes an Exception
javax.servlet.ServletException: BeanUtils.populate org.apache.struts.util.RequestUtils.populate(RequestUtils.java:469) org.apache.struts.chain.commands.servlet.PopulateActionForm.populate(PopulateActionForm.java:50) java.lang.IllegalArgumentException: No bean specified org.apache.commons.beanutils.PropertyUtilsBean.getPropertyDescriptor(PropertyUtilsBean.java:751)
My JSP looks like this:
And here is my form. My form has a Data Bean Attribute
My field StripMap references a POJO class.
Basically I'm trying to display a table with checkbox in it and during the first time that my JSP load, everything went fine and it displays what I have expected. The problem is when I am submitting the form, it causes the exception.
My Mainform is in request scope. I have read the Struts FAQ regarding changing my object into STRING but I dont know how will I implement such. Is it not advisable to use Bean Object into ActionForm and should I just place all my StripMap property directly into the actionform?
Thanks for the help..

Thanks for the help as always. I miss that instantiation part..
I'm just wondering, while trying to solve my problem, I browse into the Search of previous struts post and found some good advise regarding this exception.
One of which is to place my actionform into session scope instead of the request scope. I have tried it and it worked fine. But I am not into session scope and would prefer request scope.
Does it mean when I place my actionform into session scope, Struts takes care of all the instantiation of every databean in my form? Thanks again..

No, it doesn't. The same rules apply. The only difference is that once you instantiate a property of a session-scoped bean, it stays instantiated as long as the user remains signed on. With a request-scoped bean, the properties have to be re-instantiated with every new request.
