Struts2 input values ​​are lost when interceptor is called

Question

I have a problem with Struts2

This is my action configuration, before playing the role of Dete in Action, the interceptor is a call, but after that the input values ​​are lost, there is no identifier to delete, if I delete the interceptor and then id delete exists, can someone help me solve this problem ?

<action name="roleDelete" method="roleDelete" class="com.webapp.role.action.RoleAction">
  <interceptor-ref name="validateUser"/>
  <result name="input" type="tiles">usertypePage</result>
  <result name="success" type="redirect">usertypeForm</result>
</action>

thank

It looks like you have defined a custom validateUser interceptor stack that does not include the required Struts 2 interceptor. By default, Struts 2 calls the following interceptors on each request if you do not define your own stack (as you did):

        <interceptor-stack name="defaultStack">
            <interceptor-ref name="exception"/>
            <interceptor-ref name="alias"/>
            <interceptor-ref name="servletConfig"/>
            <interceptor-ref name="i18n"/>
            <interceptor-ref name="prepare"/>
            <interceptor-ref name="chain"/>
            <interceptor-ref name="debugging"/>
            <interceptor-ref name="scopedModelDriven"/>
            <interceptor-ref name="modelDriven"/>
            <interceptor-ref name="fileUpload"/>
            <interceptor-ref name="checkbox"/>
            <interceptor-ref name="multiselect"/>
            <interceptor-ref name="staticParams"/>
            <interceptor-ref name="actionMappingParams"/>
            <interceptor-ref name="params">
              <param name="excludeParams">dojo\..*,^struts\..*</param>
            </interceptor-ref>
            <interceptor-ref name="conversionError"/>
            <interceptor-ref name="validation">
                <param name="excludeMethods">input,back,cancel,browse</param>
            </interceptor-ref>
            <interceptor-ref name="workflow">
                <param name="excludeMethods">input,back,cancel,browse</param>
            </interceptor-ref>
        </interceptor-stack>

     <interceptors>
        <interceptor name="vendorStoreInterceptor" class="br.org.myapp.actions.interceptors.VendorStoreInterceptor"></interceptor>

        <interceptor-stack name="defaultStack">
            <interceptor-ref name="exception"/>
            <interceptor-ref name="alias"/>
            <interceptor-ref name="servletConfig"/>

    </interceptors>

    <default-interceptor-ref name="mainStack"/>

. defaultStack ( "-" "vendorStoreInterceptor" "defaultStack" ).
