Some "small" APEX 4.0 EA3 features...

In the latest release of APEX 4.0 (available on tryapexnow) I noticed two nice new features. First of all, on the far right side of the Home page of the builder, there is a little region called "Available Updates". If you click on the little "i" in the upper right of that region, you'll navigate to another page where you can control if you want to check for those updates. Wonder what will happen if I set it to "No"...will it be switched of for just my workspace or for the whole APEX instance? To me it seems it should be an "Administration" kind of functionality - so instance wide. In the "Help" it says: "This attribute controls if Application Express should check if updates are available for Oracle Application Express and the Oracle Application Express Listener. Note: To perform this check Application Express transmits the version number of Application Express and other system components to Oracle Corporation." This seems like a nice functionality to get a sort of alert if there is a patch available. I don't know if you need a Metalink account to enable this feature.
The second one is a "Set Screen Reader Mode On" link at the bottom. If you click that a SET_SESSION_SCREEN_READER_ON is added to the URL of the Builder. I assume that this means that all HTML rendered can be read by a screen reader like JAWS to enhance the accessibility of APEX for visually impaired developers.
I inspected the HTML source of that page before and after that setting and it seems that nothing has changed. Maybe because all rendered HTML is already "screen reader ready"?
Next to these things there are a lot of new features in APEX 4.0. Check out the New Features Application to see a dozen of nice examples. Also check out the Learn More About Oracle Application Express application - which seems a Websheets application to me....

Showing a success message after closing a modal dialog

APEX 5 comes with Modal Dialogs out of the box. Very neat. Especially for adding and changing data. And to minimise the number of time a user has to click, it could be useful to add a "Close Dialog" process after the actual data processing. When the data processing fails, the Dialog stays on top showing the error. When data processing runs fine, the Dialog is closed ... without any confirmation. And this might be scary for a shaky user.

So how can we provide the user some feedback? On Page 4 of the Sample Dialog Application you can see one solution: up on a Dialog Closed Event on the parent page it does a redirect to refresh the parent page appending the success message of the "Close Dialog" process. This has two drawbacks. First, it probably refreshes more than necessary. And second, if you're using multiple layers of dialogs (dialogs that open other dialogs) the message appears in the "parent dialog".
As an alternative you could follow these steps: 1…

It's happening again ... running for the ODTUG Board of Directors 😉

For the third time in a row I'll be running for ODTUG's Board of Directors. But after ending as a runner up twice, I am sure I'm going to make it this time! But not without your help!

My campaign statement this year is:
I have been attending and presenting at Kscope conferences since 2007. This not only resulted in a vast amount of knowledge, but also - and even more important - a huge number of friends from all over the globe.  I want to see ODTUG grow and spread this community feeling even more! 
My experience as an attendee, presenter and content lead has provided the basic foundation to be a director. Next to that, my personality and (global) network will be beneficial to the whole board and organization. 
Since March I have served on the Board of Directors in a limited term for a Director who stepped down due to a career change. This has allowed me to have unique insight of all the things that are going on in and around the ODTUG organization. As the train was already ro…

Consuming a REST Web Service returning JSON in APEX

In APEX you can define a web service that returns XML as below - all declarative, just a few steps through a wizard.


Then generate a report on top of that web service - again just a few clicks through a wizard. The generated query looks like this:
select xtab."customerName"      , xtab."customerId"   from apex_collections c,            XMLTable('/Response/S_getCustomerListTableArray/S_getCustomerListArrayItem' passing xmltype001             COLUMNS "customerName" PATH 'customerName'                   , "customerId"   PATH 'customerId'           ) xtab  where c.collection_name = 'CUSTOMERLIST'
So the result of the web service is stored in an XMLTYPE column. And it's easy to spot where you're definitions for the Response XPath and Output Parameters are used.
But what if your web service returns JSON - as more and more web services will do so? If you switch the Output Format of the web service definition to JSON, th…
