Struts2 submit form doesn't navigate to new view - struts2

Question

I'm using Struts2 (version 2.5.14.1) with the Spring and Tiles plug-ins.
This is my (relevant) struts.xml configuration:
<package name="enrollment" namespace="/enrollment" extends="struts-bean-validation">
<result-types>
<result-type name="tiles" class="org.apache.struts2.views.tiles.TilesResult" />
</result-types>
<action name="start" class="io.shido.struts.action.enrollment.StartAction">
<result name="success" type="tiles">enrollment.start.tiles</result>
</action>
<action name="personal-info" class="io.shido.struts.action.enrollment.PersonalInfoAction">
<result name="input" type="tiles">enrollment.personal-info.tiles</result>
<result name="success" type="tiles">enrollment.billing-info.tiles</result>
</action>
<action name="billing-info" class="io.shido.struts.action.enrollment.BillingInfoAction">
<result name="input" type="tiles">enrollment.billing-info.tiles</result>
<result name="success" type="tiles">enrollment.finish.tiles</result>
</action>
<action name="finish" class="io.shido.struts.action.enrollment.FinishAction">
<result name="success" type="tiles">enrollment.finish.tiles</result>
</action>
</package>
...the JSP file that holds one of the forms:
<%# taglib prefix="s" uri="/struts-tags" %>
<link rel="stylesheet" href="<s:url value='/resources/styles/enrollment.styles.css' />">
<s:form cssClass="form-input-info" action="personal-info" method="post">
<legend><s:text name="legend.text" /></legend>
<hr>
<s:textfield cssClass="form-control" key="textfield.first-name" name="personalInfo.firstName" />
<s:textfield cssClass="form-control" key="textfield.last-name" name="personalInfo.lastName" />
<s:textfield cssClass="form-control" key="textfield.email" name="personalInfo.email" />
<s:textfield cssClass="form-control" key="textfield.phone-number" name="personalInfo.phoneNumber" />
<s:textfield cssClass="form-control" key="textfield.age" name="personalInfo.age" />
<s:submit class="btn btn-primary btn-lg btn-block" key="submit.continue" />
</s:form>
...and finally the (super simple) Action class:
package io.shido.struts.action.enrollment;
// imports
public final class PersonalInfoAction extends ActionSupport {
private static final long serialVersionUID = 3560814234131884357L;
private final Logger logger = LogManager.getLogger(this.getClass());
private PersonalInfoHandler handler;
#Valid
private PersonalInfo personalInfo;
#Override
public String execute() {
// If personalInfo is not null is guaranteed to be valid due to Bean Validation contraints
if (null != personalInfo) {
logger.debug("Processing personal info...");
handler.save(personalInfo);
return Action.SUCCESS;
}
logger.info("Collecting personal info...");
return Action.INPUT;
}
public PersonalInfoHandler getHandler() { return handler; }
public void setHandler(final PersonalInfoHandler handler) { this.handler = handler; }
public PersonalInfo getPersonalInfo() { return personalInfo; }
public void setPersonalInfo(final PersonalInfo personalInfo) {
this.personalInfo = personalInfo;
this.personalInfo.normalize();
}
}
The issue is, whenever I submit that form, I'm expecting the Bean Validation to kick out and check all the annotated fields (check, this is happening) and when everything is fine, send the flow to /WEB-INF/content/enrollment/billing-info.jsp (defined in Tiles by enrollment.billing-info.tiles)...but all I see is (almost) the "billing info" form with the wrong labels. See the below picture:
The URL should have changed, as well as the labels. To put the cherry on top, if I click the Continue button again, the form is displayed then correctly.
Any clues?

Answer 1

I have no direct answer but you could try to use a redirect action instead of using the tiles several times.
So you could try this here:
<action name="personal-info" class="io.shido.struts.action.enrollment.PersonalInfoAction">
<result name="input" type="tiles">enrollment.personal-info.tiles</result>
<result name="success" type="redirectAction">
<param name="actionName">billing-info</param>
</result>
</action>
And if you need to transfer some kind of id to show the data you can use additional params in the struts.xml like this:
<!-- rest as above -->
<result>
<param name="param1">${value1}</param>
</result>
The param1 must have valid getter/setter-methods in both actions to transfer the information.
