RE: ParametersInterceptor setting values using a String[]
Your right: looks like SiteMesh was sending the parameters through to
another action.
Thanks for the help.

Subject: Re: ParametersInterceptor setting values using a String[]
Hi Matthew,
The params interceptor is calling setId on ActionSupport (the default
action), not on your action that has the setId method, so an exception
is
being thrown as there's no matching setter whatsoever. You may have a
config error.
All params are treated as arrays because its valid in HTTP for the same
parameter to be specified multiple times in the same request.
The default type conversion will call setId(Integer id) using the first
element in the array if that's the first property to be matched.
The error is only logged when the exception occurs and this is
*infrequent* in normal use.
Hope that helps!
regards,
Jeromy Evans
This appears to have been mentioned a number of times in the Struts 2
and XWork forums but I cannot find a real answer:
Using Struts 2.0.11 I am experiencing the following problem.
I have an action with the method
setId(Integer id) { ... }
When this value is set via a HTTP request through the
ParametersInterceptor it succeeds when using both GET and POST.
However
when a GET is performed I get the following exception logged
SEVERE: ParametersInterceptor - [setParameters]: Unexpected Exception
caught setting 'id' on 'class com.opensymphony.xwork2.ActionSupport:
Error setting expression 'id' with value '[Ljava.lang.String;@1a1f635'
XWork appears to store the a single GET parameters as an array of
Strings and attempt to set the value using the String[] first, when
that
errors tries to convert it. The problem with this is it logs the first
failure as an ERROR.
Why is this happening and short of creating my own TypeConverter or
blocking it in the logger config, how can I stop this error being
logged
for GET requests?

RE: ParametersInterceptor setting values using a String[]
Thanks for the prompt response. Having had a look at the code in Xwork
that comes as part of Struts 2 (included below) it seems to log it
regardless of the devMode.
This is the same for 2.0.4 and 2.1.0.
I cannot believe this hasn't been spotted before now, so I assume I am
doing something wrong.
try {
stack.setValue(name, value);
} catch (RuntimeException e) {
if (devMode) {
String developerNotification =
LocalizedTextUtil.findText(ParametersInterceptor.class,
devmode.notification, ActionContext.getContext().getLocale(),
Developer Notification:\n{0}, new Object[]{
e.getMessage()
});
LOG.error(developerNotification);
if (action instanceof ValidationAware) {
((ValidationAware)
action).addActionMessage(developerNotification);
}
} else {
LOG.error(ParametersInterceptor - [setParameters]: Unexpected
Exception caught setting '+name+' on '+action.getClass()+: +
e.getMessage());
}
}
