ParameterIntercepter throws unexpected Exception on parameter

["Kropp, Henning" <hk...@microlution.de>]

Hi List,

the ParameterIntercepter throws the following exception at my page:

ERROR [btpool0-1] ParametersInterceptor.setParameters(204) | 
ParametersInterceptor - [setParameters]: Unexpected Exception caught 
setting 'button.regi
ster' on 'class com.webapp.action.SignupAction: Error setting expression 
'button.register' with value '[Ljava.lang.String;@62e8c8'

Well, the parameter 'button.register' is a key value for <s:button /> . 
I don't understand why this Exception is thrown and have no clue how to 
track the issue down.
The SignUpAction uses besides a save() method an execute() method. The 
execute() method is primarly used to distinguish between get and post 
methodType.

Any given aspects will be appreciated.

thx

As discussed in another thread today, this message is only reported with 
devMode set to true.

If you don't want the parametersInterceptor to attempt to set that 
parameter, make sure it's not sent by the browser.  To do this, ensure 
that the generated form input/button has no name attribute set.
