Hello,
I got a problem with type conversion errors.
I have several custom type converters which throw a
TypeConversionException in case the conversion fails. However, the
conversionError interceptor does not add any field errors to the action
in that case; furthermore, it seems that struts rather tries to set the
un-converted String, leading to an error message from the parameters
interceptor:
SEVERE: ParametersInterceptor - [setParameters]: Unexpected Exception
caught setting 'xxx.ipAddress' on 'class
xxx.NidsCustomerApplicationAction: Error setting expression
'xxx.ipAddress' with value '[Ljava.lang.String;@6dafa36'
(There is no setIpAddress(String) method, which is correct; I think this
should never happen in the first place)
When there is no TypeConversionException, everything works fine (=> the
type converter is called and works).
I have verified (using a debugger) that the ConversionErrorInterceptor
gets called. It calls invocationContext.getConversionErrors(), but that
method returns an empty map. However, after the TypeConversionException
is thrown, an error message is added to the context in
XworkConverter.handleConversionException(...). It must get lost
somewhere on the way to the ConversionErrorInterceptor (?).
So my questions:
- Why does struts or xwork try to set the non-converted value as string
after conversion fails?
- Where are my error messages?
- What am I doing wrong?
Maybe there is an incompatibility among the libraries I use?
Environment:
struts 2.0.12
xwork 2.0.6
ognl 2.6.11
(tomcat 6.0.16, java 1.6.0_10 ...)
interceptor stack:
staticParams
prepare
chain
checkbox
params
conversionError
validation
workflow
(This list is reduced to the possibly relevant interceptors; there are
several custom interceptors before and after these in my stack, but I
think they should not interfere with this problem)
I would appreciate any help on with issue - thanks in advance!
Regards,
Daniel
