[jira] Created: (BEEHIVE-1141) Form bean implmenting Serializable can not populate its property attributes from HTTP GET request parameters

Form bean implmenting Serializable can not populate its property attributes from HTTP GET request parameters
------------------------------------------------------------------------------------------------------------

                 Key: BEEHIVE-1141
                 URL: http://issues.apache.org/jira/browse/BEEHIVE-1141
             Project: Beehive
          Issue Type: Bug
          Components: NetUI
    Affects Versions: 1.0.1
         Environment: WIndows XP SP2, Linux, w/ JDK 1.5
            Reporter: Yongqin Xu
         Assigned To: Carlin Rogers
             Fix For: v.next


a url link with request parameters like "someAction.do?param1=1&param2=3" invokes the action method "someAction" in
a controller class. The action method takes a form bean with property attributes "param1" and "param2". If the form bean extends
deprecated FormData, those bean attributes got populated correctly, otherwise, if the form bean just implements Serializable
interface as those created from weblogic workshop 9.2 IDE wizard, its attributes can not get populated at all.

[jira] Resolved: (BEEHIVE-1141) Form bean implmenting Serializable can not populate its property attributes from HTTP GET request parameters

Posted by "Carlin Rogers (JIRA)" <de...@beehive.apache.org>.

     [ http://issues.apache.org/jira/browse/BEEHIVE-1141?page=all ]

Carlin Rogers resolved BEEHIVE-1141.
------------------------------------

    Resolution: Fixed
      Assignee: Julie Zhuo  (was: Carlin Rogers)

Turns out that a page with a form that uses a POST will also have the behavior if the name of the field is not an expression. The NetUI tags usually create an expression from a data source (like actionForm.someParam). However, if a developer had a bean that just implemented Serializable, and had a page with a form that used did not have expressions for the name of the field, the bean would not be populated as desired. So this was broken with both GET and POST. Good catch!

The implementation for the NetUI process populate, defers to the commons BeanUtils for non-NetUI expression keys, which is what Struts uses. Before doing the populate,
a Serializable form beans gets wrapped in a NetUI AnyBeanActionForm object where as the FormData form bean is just passed through.

This issue is fixed with SVN revision 438250...
http://svn.apache.org/viewvc?rev=438250&view=rev

Modified ProcessPopulate to make sure it passes the original bean to the commons BeanUtils.populate() method, rather than the NetUI AnyBeanActionForm object. There's also a new test that uses form beans in both Get and POST requests.
