Alternative to Alternating Row Colors in an Interactive Report

Almost a year ago I blogged about a solution how to create those nice striping in an Interactive Report. That solution is based on using the onLoad method of an image that you use in the IR for linking to a Form. The downside of that solution is that it doesn't 'support' sorting and filtering. After applying a sort of a filter the coloring is all gone. Also - in some browsers - the order in which the rows (or images) are loaded is not the same order as you see on the screen, resulting in a more or less randomized striping...

But recently I found out about the l_LastFunction attribute of a report. That function is called after all worksheet (report) AJAX calls. So if we define a function that does the striping for just the odd rows in the worksheet after all calls - like sorting, filtering - are done, the striping just keeps working!


The code uses jQuery and is just this:
$(function(){
  function altColor(){
   $(".apexir_WORKSHEET_DATA tr:odd").addClass("Odd");
    setTimeout(
      gReport.l_LastFunction = function(){altColor();}
     ,1000);
  }
  gReport = new apex.worksheet.ws("");
  altColor();
});
It works in Firefox, Safari and Chrome, not sure about IE though...
And of course there is a demo...

Hi Roel,

This will overwrite the gReport.l_LastFunction right? Is this function empty? Maybe appending would be safer?

I tested in IE 7 and the alternate rows did not show up.

Refresh selected row(s) in an Interactive Grid

In my previous post I blogged about pushing changed rows from the dabatase into an Interactive Grid. The use case I'll cover right here is probably more common - and therefore more useful!

Until we had the IG, we showed the data in a report (Interactive or Classic). Changes to the data where made by popping up a form page, making changes, saving and refreshing the report upon closing the dialog. Or by clicking an icon / button / link in your report that makes some changes to the data (like changing a status) and ... refresh the report.  That all works fine, but the downsides are: The whole dataset is returned from the server to the client - again and again. And if your pagination size is large, that does lead to more and more network traffic, more interpretation by the browser and more waiting time for the end user.The "current record" might be out of focus after the refresh, especially by larger pagination sizes, as the first rows will be shown. Or (even worse) while you…

Dockerize your APEX development environment

Nowadays Docker is everywhere. It is one of the main components of Continuous Integration / Continuous Development environments. That alone indicates Docker has to be seen more as a Software Delivery Platform than as a replacement of a virtual machine.

However ...

If you are running an Oracle database using Docker on your local machine to develop some APEX application, you will probably not move that container is a whole to test and production environments. Because in that case you would not only deliver a new APEX application to the production environment - which is a good thing - but also overwrite the data in production with the data from your development environment. And that won't make your users very excited.
So in this set up you will be using Docker as a replacement of a Virtual Machine and not as a Delivery Platform.
And that's exactly the way Martin is using it as he described in this recent blog post. It is an ideal way to get up and running with an Oracle database …

apex_application.g_f0x array processing in Oracle 12

If you created your own "updatable reports" or your custom version of tabular forms in Oracle Application Express, you'll end up with a query that looks similar to this one:
then you disable the "Escape special characters" property and the result is an updatable multirecord form.
That was easy, right? But now we need to process the changes in the Ename column when the form is submitted, but only if the checkbox is checked. All the columns are submitted as separated arrays, named apex_application.g_f0x - where the "x" is the value of the "p_idx" parameter you specified in the apex_item calls. So we have apex_application.g_f01, g_f02 and g_f03. But then you discover APEX has the oddity that the "checkbox" array only contains values for the checked rows. Thus if you just check "Jones", the length of g_f02 is 1 and it contains only the empno of Jones - while the other two arrays will contain all (14) rows. So for processing y…
