Parameters Interceptor Exception

[megha maria]

Hi all,
I am trying to submit a form so as to insert a new record .I have created the getters and setters file.Once the form validation is done, it doesnt execute furthur. I get the following error
get this error in console for each form parameters..any idea wat i am missing?

10:31:00,228 ERROR [http-8080-3] com.opensymphony.xwork2.interceptor.ParametersI
nterceptor - ParametersInterceptor - [setParameters]: Unexpected Exception caugh
t setting 'FormObj.en_address' on 'class com.abc.abcActio
n: Error setting expression 'FormObj.en_address' with value '[Ljava.lang.S
tring;@983670'

Can this be because I have not used Interceptors in my struts.xml?
