ParameterNameAware issue

[Markus Demetz]

Hi,

I am trying to upgrade my application from 2.3.15.2 to 2.3.16.3.
Some of my actions implement the ParameterNameAware interface to check 
if a parameter will be accepted.
I have parameters of the form like user.username (e.g. loginform) 
which will be passed to the acceptableParameterName(String) function of 
the LoginAction class.
The LoginAction has a User Object with a setUsername method. I didn't 
want to use the model-driven approach.


When upgrading to struts 2.3.16.3 the acceptableParameterName function 
is getting called multiple times with different combinations: 
user.username, user and username.

Is it wrong to use dots in parameter names?
Any suggestions?

Best regards,
Markus Demetz

  Don't know why. I suspect you have a class name conflict somewhere
 in your
  environment.

   I am attaching the struts.xml file. This is the struts.xml file
 that came
   with the tutorial example. I have not
   edited it at all.
  
   I realize the stack track indicates the program failed in the
 struts.xml
   file, but I assume that
   for most people running the example, this example works. I suspect
 that
   the this code makes assumptions
   about the environment and that my environment does not meet all of the
   assumptions. I have no idea where
   to look for the root cause at this point.

   The backtrace already told you. There's a classcast exception in your
   struts.xml file.
   You need to at least add your struts.xml file.

   Hi,
  
   I'm trying to learn about struts and I have been trying to run the
   tutorials. The example, 'basic struts', runs ok in my
   environment. But when I run 'hello_world', I get a stack trace,
 which I
   will attach to this email.
  
   I'm running on Crunchbang linux, a Debian deriviative, and I'm using
   tomcat6 as my server, with Struts 2.3.16.3.
  
   I was having trouble getting the example to run on my machine. I
 finally
   got it to run successfully once. Every run
   after that has given me a stacktrace. I figured that I might have
 messed
   up the code in my work space, so I removed
   everything, re-installed the hello_world directory and then
 rebuilt using
   'mvn clean package', which ran
   successfully. I tried installing the war file both manually and
 using the
   tomcat manager and got the same results
   in either case.
  
   I am searching the internet for a similar stacktrace, but have
 not found
   it yet. Has anyone on the mailing list
   seen a similar problem before?
  
   Regards,
   Jim Anderson
