problem in populating Maps
hi,
I am trying to populate a LinkedHashMap located in a DTO from a
<s:textfield.. /> When i turn on the debug mode i seed the following error
on the console:
ERROR (com.opensymphony.xwork2.interceptor.ParametersInterceptor:199) -
Developer Notification (set struts.devMode to false to disable this
message):
Error setting expression 'currentEvent.excludeRulesValues['dd']' with value
'[Ljava.lang.String;@1f09665'
424209 [http-8080-Processor24] ERROR
com.opensymphony.xwork2.interceptor.ParametersInterceptor - Developer
Notification (set struts.devMode to false to disable this message):
I am using the following syntax in the jsp:
< td >
Ignore people who have been given >= <s:textfield
name="current.rules['dd']" />
offers previously from EDS< /td >
The action class is having current defined as a Dto with getters and
setters, and rules is the LinkedHashMap defined in the DTO with getters and
setters. The constructor of the Action class instantiates the 'current'
variable and constructor of Dto instantiates the 'rules' variable of DTO.
and in the textbox generated i entered dd as the input text.
Any ideas why this is not working???
regards,
ravi

And how do we might fix this thing..?
I can understand that a <s:select /> can return several String values,
but a <s:textfield /> ...?!
And even if the HTML/HTTP or what-so-ever standard involved allows
that multiple values are returned for the same parameter (what seems
to be commonly argued in this situation), why setting the value for a
single String field in an Action do not lead to this exception?!

That's unlikely; the error is this:
>> Error setting expression 'currentEvent.excludeRulesValues['dd']' with
>> value '[Ljava.lang.String;@1f09665'
which looks more like it's trying to set a single String with a String[].

Why not? I don't have any issues using those characters as map values or
displaying (or submitting) them in <s:textfield...>s.

1)
its possible the link does'nt have that returned object mapped
you may want to consider doing a quick test of the object beforehand with
linkObject.containsValue(ReturnedObject)
http://java.sun.com/javase/6/docs/api/java/util/LinkedHashMap.html#containsV
alue(java.lang.Object)
2)
it is quite possible you have *may* a stale TO
http://java.sun.com/blueprints/corej2eepatterns/Patterns/TransferObject.html
have you considered using a factory with Timestamps/Versions to either
quiesce the old TOs or somehow update old contents with new?
3)s:textfield
Whichever value is being returned from the LinkedMap's value has to not have
these embedded chars
