How to get request attribute value at *.ftl?

[Chen Xi]

Hi：
    May I know how to retrieve value from the request.

    I have retrieve the value at one java class. like
    List projects = (List) result.get("projects");  // It is not null
    request.setAttribute("projects", projects);

    However, at the *.ftl file, i try to use
    <#if projects?has_content>
                   <#list projects as Project>
                       <tr>
                          <td>${Project.project_id}</td>
                          <td>${Project.name}</td>
                       </tr>
                    </#list>
    </#if>

    there is no result to display. Seems projects is empty, is it any
important steps i missed?

Hi,

  In your ftl, you will need to fetch the attribute set in the request as
follows:

    <#assign projects = requestAttributes.projects?if_exists >

    <#if projects?has_content>
       <#list projects as Project>
          <tr>
        <td>${Project.project_id}</td>
             <td>${Project.name}</td>
          </tr>
       </#list>
    </#if>



Thanks,
