Subject REST question
Date Tue, 11 Feb 2014 05:40:20 GMT
Hi,

A strange situation happens when I load *struts2-rest-plugin-2.3.16.jar*
With out the REST plugin my action and jsp's works as always has worked.
But with the mere inclusion of the REST Plugin, some jsp's stops finding
variables, because the variable name changes.
Here is the snippet:

struts.xml

    <constant name="struts.objectFactory"
value="org.apache.struts2.spring.StrutsSpringObjectFactory" />
    <constant name="struts.objectFactory.spring.autoWire" value="name" />
    <package name="proyectox" extends="json-default" >
<!-- Si no le pones este stack, pues no funciona...-->
        <interceptors>
            <interceptor name="strutsSpring"
class="com.proyectox.ui.interceptor.HibernateOpenSessionInViewInterceptor"/>
            <interceptor name="viewuseragentselector"
class="com.proyectox.ui.interceptor.UserAgentResultInterceptor"/>
            <interceptor-stack name="strutsSpringPPPStack">
                <interceptor-ref name="strutsSpring"/>
                <interceptor-ref name="paramsPrepareParamsStack"/>
                <interceptor-ref name="viewuseragentselector"/>
            </interceptor-stack>
        </interceptors>
...
    </package>

    <package name="cfdi" extends="proyectox" namespace="/cfdi">
        <action name="header_*" class="com.fcm.cfdi.ui.HeaderAction">
            <result type="redirectAction">
                <param name="actionName">edit</param>
            </result>
<!--            <result >printHeader.jsp</result>-->
            <result name="input">headerEdit.jsp</result>
            <result name="error">/facturaerror.jsp</result>
            <interceptor-ref name="scope">
                <param name="session">contribuyente</param>
                <param name="autoCreateSession">true</param>
                <param name="key">contribuyenteActual</param>
            </interceptor-ref>
            <interceptor-ref name="scope">
                <param name="session">factura</param>
                <param name="autoCreateSession">false</param>
                <param name="key">cfdi</param>
            </interceptor-ref>
            <interceptor-ref name="strutsSpringPPPStack"/>
        </action>



HeaderAction.java:

public class HeaderAction extends ActionSupport implements Preparable {
    protected Contribuyente contribuyente;
    protected Long contribuyenteId;

    public void prepare() throws Exception {
    ...
    }


    public String input(){

        dirReceptorId = factura.getDomicilioReceptor().getId();
        dirEmisionId  = factura.getDomicilioEmision().getId();
        return INPUT;
    }
...
    public Contribuyente getContribuyente() {
        return contribuyente;
    }

    public void setContribuyente(Contribuyente contribuyente) {
        this.contribuyente = contribuyente;
    }
...
}

edit.jsp:
...
    <s:select label="Direccion Emision"
       name="dirEmisionId"
       list="*contribuyente*.domicilios"
       listKey="id"
       listValue="nombre"
       multiple="false"
       size="1"
       required="true"
       key="factura.direccionEmision.id"
    />
...

After loading *struts2-rest-plugin-2.3.16.jar* it starts giving the
following exception:
Caused by: org.hibernate.LazyInitializationException: failed to lazily
initialize a collection of role: *contribuyentes.domicilios*, no session or
session was closed
...

I know that's a Hibernate exception, but the jsp works fine without the
REST Plugin.
It's like the REST Plugin appends that extra "s" after the variable name in
the .jsp or the value stack changes or something like that.

The action is invoked without error in either case, and has into it's
fields the required values.


Does anyone has any pointer of what can be happening?

Thanks
