Error in HtmlReportService when building ReportPlugin for ContentCreator

Hello,

FirstSpirit 5.1.605.IE 9/Chrome 34.

I have been building a ReportPlugin, which lists Pages according to various criteria. The basic plugin is working in SiteArchitect, and the report appears in ContentCreator. But when I mouse over the Report item, or click on it, an error is thrown.

In the web browser console the error is:

On the server, the logs show:

[–] 11:46:54 DEBUG 01.08.2016 11:46:54.707 (fs.webedit.server.report.HtmlReportManager) [...] 01.08.2016 11:46:54 DEBUG 01.08.2016 11:46:54.707 (de.espirit.firstspirit.webedit.server.report.HtmlReportManager): Created report-proxy, handle=715816598, type=PluginReportType{_type=uk.gov.scotland.afrc.firstspirit.contentreports.PageContentReportPlugin,renderer:false}, sessionID=3601705410209406750, user=d416936

Then:

I can't find any reference to HtmlReportManager or HtmlReportService in the FirstSpirit documentation, so I don't know what I've done wrong or forgotten to do.

My ReportItem looks like this code. The logging message "Navigating to..." never appears in the logs:

public class AFRCReportItem extends ReportType implements ReportItem<IDProvider>, JavaClientExecutableReportItem<IDProvider>,

                    WebeditExecutableReportItem<IDProvider> {

...

public void execute(ReportContext<IDProvider> reportContext) {

                    final IDProvider idProvider = reportContext.getObject();

                    reportContext.logDebug("++++ Navigating to " + idProvider.getUid() + ", class: " + idProvider.getClass().getName());

                    if (!reportContext.is(BaseContext.Env.WEBEDIT)) {

                              reportContext.requireSpecialist(OperationAgent.TYPE).getOperation(DisplayElementOperation.TYPE).perform(idProvider);

                    } else {

                                   PageRef pageRef = null;

                                   for (final ReferenceEntry inboundReference : idProvider.getIncomingReferences()) {

                                                  if (inboundReference.getType() == ReferenceEntry.SITE_STORE_REFERENCE) {

                                                            final IDProvider referenceElement = inboundReference.getReferencedElement();

                                                            if (referenceElement instanceof PageRef && idProvider.equals(((PageRef) referenceElement).getPage())) {

                                                                      pageRef = (PageRef) referenceElement;

                                                       }

                                        }

                              }

                              if (pageRef != null) {

                                             final OperationAgent operationAgent = reportContext.requestSpecialist(OperationAgent.TYPE);

                                             final DisplayElementOperation displayElementOperation = operationAgent.getOperation(DisplayElementOperation.TYPE);

                                             if (displayElementOperation != null) {

                                                       displayElementOperation.setLanguage(reportContext.getObject().getProject().getMasterLanguage());

                                                       reportContext.logDebug("++++ Navigating to " + pageRef.getUid() + "");

                                                       displayElementOperation.perform(pageRef);

                                             }

                              }

                    }

          }

The report only lists Pages, and when the user clicks on the page the ContentCreator should navigate to that page, as it does in SiteArchitect.

Many thanks,

Liam Davison
