Velocity Template for Webwork Action is missing Context

[Christian Werner]

Hi all,

I am currently trying to create a Jira Plugin and am struggling with context provision for a velocity template that is being used in a webwork module. 

I created a Web-Panel first, where it was possible to reference a ContextProvider class and everything worked fine.

Now, I want to build pretty much the same page, but instead of using a Web-Panel I want to use a Webwork module. The problem for me here is, that my velocity template is somehow missing context and in comparison to the Web-Panel I am not providing one (no context-provider). How can I make the context known to the velocity template?

I am kind of new in software development and thus the solution may be very simple, but for me unfortunately it is not. I would be very greatful, if anyone could explain to me (in a simple and understandable way) how I can solve my problem. Thanks in advane!

Here are the important code snippets.

Webwork:

<webwork1 key="project-panel-module" name="Project Panel Module" i18n-name-key="project-panel-module.name"> 
  <description key="project-panel-module.description">The Project Panel Module Plugin</description>  
  <actions> 
    <action name="com.atlassian.jira.testtron.webwork.ProjectPanelAction" alias="ProjectPanelAction">
        <view name="project-panel">/templates/project/project-panel.vm</view>
    </action>
  </actions> 
</webwork1>

ProjectPanelAction class:

@SupportedMethods({RequestMethod.GET})
public class ProjectPanelAction extends JiraWebActionSupport
{
    private static final Logger log = LoggerFactory.getLogger(ProjectPanelAction.class);

    @Override
    public String execute() throws Exception {

      return "project-panel";
    }

}

Context Provider class that worked for the Web-Panel:

@Named
public class JobPanelContextProvider implements ContextProvider {

   private final JobServiceAdapter jobServiceAdapter;

   @Inject
   public JobPanelContextProvider(JobServiceAdapter jobServiceAdapter) {
      this.jobServiceAdapter = jobServiceAdapter;
   }

   @Override
   public Map<String, Object> getContextMap(Map<String, Object> context) {
      final ResultDisplay jobDisplays = jobServiceAdapter.readFeatureJobListForHead();
      context.put("resultDisplay", jobDisplays);

      return context;
   }
}

Part of the Velocity Template. Basically none of the variables can be resolved:

<table id="delayedSortedTable" class="aui aui-table-sortable">
    <thead>
    <tr>
        <th>Issue</th>
        <th>Erfolgreich</th>
        <th>Fehlgeschlagen</th>
        <th>Total</th>
        <th class="aui-table-column-unsortable"></th>
    </tr>
    </thead>
    <tbody>
        #foreach( $job in $resultDisplay.jobs )
        <tr>
            <td><a href="$job.issueLink">$job.issueDisplayName</a></td>
            <td>
                <aui-badge>$job.successful</aui-badge>
            </td>
