• in my application I was still using the Object[][] way to populate the table pages. So on the server side I have a method
  

  Object[][] getXxxData(SearchFilter filter);

  
  On the client side, I used the following method:
  

    @Override
    protected Object[][] execLoadTableData(SearchFilter filter) throws ProcessingException {
      return SERVICES.getService(IXxxxService.class).getXxxData(filter);
    }

  
  Apparently execLoadTableData() no longer exists, so I replaced this with the following code:
  

    @Override
    protected void execLoadData(SearchFilter filter) {
  	  Object[][] xxxData = BEANS.get(IXxxService.class).getXxxData(filter);
  	  getTable().replaceRowsByMatrix(xxxData);
    }

  
  This seems to work in as far as the server code is called and data is returned, but it is never shown in the table. Instead there is an error dump in the ui-html-dev console listing a ton of JSON errors that don't help me (sadly I forgot to copy paste them from my home computer where I managed to get Neon working, I'll append them to this post tonight). However, when clicking on the table headers (which are visible) the values are offered for filtering, so it seems that they ended up on the client at least partially...
  Is this not the recommended way to populate table pages any more? I know that TableFormData was introduced a while back, but I never got around to converting my applications (both privately and at work).
  
• my tables have context menus that make liberaly use of execPrepareAction() (yes, I know it has been deprecated since Mars) and execAboutToShow() (which I believe was the recommended alternative in Mars). Neither of those methods seem to available anymore. How do I conditionally enabled/disable context menus on tables in Neon?
  
• the ScoutInfoForm seems to have problems calculating its correct size. Showing it, not all lines are shown and there is no initial scrollbar. Only after resizing that window is the scroll bar added. Is this a known Neon-Bug?
  
• in my application I had added support for Jasper Reports following the how to on the Scout Wiki. There are some code parts that seem to be bundle based that I am uncertain on how to migrate:
  In ReportService.createReport() there is
  

        URL url = new URL("platform:/plugin/ch.bee.mediathek.reports/reports/" + reportName + ".jrxml");
        InputStream inputStream = url.openConnection().getInputStream();

  
  How does that need to be migrated?
  Then on the client side there was
  

            byte[] report = BEANS.get(IReportingService.class).createReport(ids, "DvdList", getConfiguredText());
            BEANS.get(IFileService.class).openPdfFile(report);

  
  which in turn calls the file service which implemented openPdfFile() as follows:
  

    public void openPdfFile(byte[] contents) throws ProcessingException {
      if (contents.length > 0) {
        // get a path to save the file
        File tmpPath = Activator.getDefault().getStateLocation().toFile();
        File tmpFile;
        try {
          String extension = ".pdf";
          String name = "report-";
          // get e unique temporary name
          tmpFile = File.createTempFile(name, extension, tmpPath);
          FileOutputStream fo = new FileOutputStream(tmpFile);
          fo.write(contents);
          fo.close();
          // let the vm handle the deletion of the temp file
          tmpFile.deleteOnExit();
          // use the ShellService to open the associated program
          BEANS.get(IShellService.class).shellOpen(tmpFile.getAbsolutePath());
        }
        catch (IOException e) {
          throw new ProcessingException("Can't create or write to tmp File.", e);
        }
      }
      else {
        throw new ProcessingException("Can't open report file.");
      }
    }

  
  What is the suggested way to create this temporary file in the correct location and does the ShellService still exist and work to display the resulting PDF file?
  Also, I have extended the createReportMethod() to provide the file path to clien/resource/icons so they could be used in the report. In order to do that I wrote the following method:
  

    private String getIconPath() {
      String clientBundleName = Activator.getDefault().getBundle().getSymbolicName().replace(".server", ".client");
      return BundleUtility.getBundlePath(clientBundleName, "/resources/icons");
    }

  
  How do I migrate this to provide the new icon path?
  
• all my tabel pages have a corresponding SearchForm. In the search form there was an interface method startSearch() which apparently no longer exists on the interface. I just removed the @Override annotation but do not see the search form on the gui (or only on one table pages and even there only partially). What is the recommended way of associating search forms to table pages in Neon?
  

I did not process each of your points yet.

execLoadTableData() => execLoadData() was announced with mars:
https://wiki.eclipse.org/Scout/NewAndNoteworthy/5.0#Deprecate_execLoadTableData.28.29_in_table_pages

My advice at this point is:
Before you start, you should have a Mars application with as less as possible warnings.

In Mars I did not have any warnings when using execLoadTableData().

My html-ui-dev console shows the following error and the web gui shows the error attached below.

all my tabel pages have a corresponding SearchForm. In the search form there was an interface method startSearch() which apparently no longer exists on the interface. I just removed the @Override annotation but do not see the search form on the gui (or only on one table pages and even there only partially). What is the recommended way of associating search forms to table pages in Neon?
