Struts 2 JCaptchaforStruts 2 issue

[Joe San]

Guys,

I'm using the Struts2 J Captcha plugin as it is available from this website http://code.google.com/p/jcaptcha4struts2/wiki/QuickStart

Everything works fine bu I'm not just able to retain my form values whenever I enter a wrong value for the captcha. The form values are reset. I'm really clueless as to where the captcha validation happens and what results when the validation fails. Does anyone have an idea on this?

Here is my action mappting:

        <action name="register" class="userAction" method="registerNewUser">
            <!-- Interceptor Stack -->
            <interceptor-ref name="registrationStack"/>
        
            <result name="success" type="tiles">registerSuccess</result>
            <result name="input">/register.jsp</result>
            <result name="error">/register.jsp</result>
		</action>

where register.jsp is the jsp page for the form input and a snippet of it would look like as below:

<s:form action="/user/register" id="registerUserForm">
<TABLE BORDER=0    >
 	<TR>		
 		<TD><s:textfield name="userDetails.firstName" id="firstName" label="First Name" required="true"/></TD>
 	</TR>
 
 	<TR>
 		<TD><s:textfield name="userDetails.lastName" id="lastName" label="Last Name"  required="true"/></TD>
 	</TR>
 	
 	<TR>
 		<TD><s:textfield name="userDetails.email" id="email" label="Email"  required="true"/></TD>
 	</TR>
 	
 	<TR>
 		<TD><s:textfield name="emailConfirm" id="emailConfirm" label="Confirm Email"  required="true"/></TD>
 	</TR>
 	
 	<TR>
 		<TD><s:textfield name="userDetails.mobile" id="contactNumber" label="Contact Number" /></TD>
 	</TR>	
 
 	<TR>
 		<TD><s:select label="Please select your occupation" 
 		              headerKey="-1" headerValue="--  Please Select  --"
 		              list="{'Student', 'Software Developer', 'Software Architect', 'IT Trainer', 'Other'}" 
 		              name="userDetails.occupation" id="occupation"/>
 		    <div class="hiddenElem">
 				<s:textfield name="otherOccupation" id="otherOccupation" style="display:none"/>
 			</div>
 		</TD>
 	</TR>
 
 
 <TR><TD>
 	
 	<div class="jCaptcha">
 		<!-- The JCaptcha Control -->
 		<jcaptcha:image label="If you are human, then enter the text in the text box below!" width="100"/>
 	</div>
 </TD></TR>
 </TABLE>	
	<div class="submitBtn"><s:submit value="Submit Registration"/></div>
</s:form>

Allright. Figured out the issue. It was because of the fact that the JCaptchaForStruts2 interceptor does not implement ModelDriven and Preparable interfaces. Found a decent workaround for this solution.
