Hi guys,

I have tried to build a sample from Dave's blogpost (http://blogs.alfresco.com/wp/developer/2014/11/20/aikau-using-the-alfdocumentpreview/)
Just wanted to create a preview-dialog on a pdf-file, which should open when a button is clicked.



The AlfrescoDocumentPreview.js requires the "alfresco/preview/PdfJs"- module within the "setupPlugins" function. Then the constructor-function of PdfJs gets called. Everything is fine, but unfortunately it seems as if the code where the "Alfresco.WebPreview.prototype.Plugins.PdfJs.prototype" - Object/Mixin/Whatever is added never executes?
Cause later on i fall into the exception that the "onComponentsLoaded"-function is missing when the plugin tries to display.

I definitely missed something. Any ideas on this?

previewAction: function () {
           
           console.log("Within Preview try");
           
           var vs = win.getBox();
           
           var nodeRef = "workspace://SpacesStore/" + this.entry.id;
           
           this.payload = {
                    contentWidth: (vs.w*0.7) + "px",
                    contentHeight: (vs.h-64) + "px",
                    handleOverflow: false,
                    dialogTitle: "PreviewTitle",
                    additionalCssClasses: "no-padding",
                    widgetsContent: [
                       {
                          name: "alfresco/documentlibrary/AlfDocument",
                          nodeRef: nodeRef,
                          config: {
                             widgets: [
                                {
                                   name: "alfresco/preview/AlfDocumentPreview"
                                }
                             ]
                          }
                       }
                    ],
                    widgetsButtons: [
                       {
                          name: "alfresco/buttons/AlfButton",
                          config: {
                             label: "close",
                             publishTopic: "NO_OP"
                          }
                       }
                    ],
                    publishOnShow: [
                       {
                          publishTopic: "ALF_RETRIEVE_SINGLE_DOCUMENT_REQUEST",
                          publishPayload: {
                             nodeRef: nodeRef
                          }
                       }
                    ]
           };

Hi Christian… quick question - are you doing this within the Share application? E.g. as an extension to Share? The reason I ask is that we're currently doing some rather "interesting" prototype manipulate to get the PDFjs previewer working in Aikau which currently relies on it running within the context of the Share application. We're going to breaking this dependency in the future.

A bit more information on the context in which you're using this code would be useful to help debug the problem.

Thanks,
Dave
