Two not-to-miss APEX events in June !

June will be a busy month. Not only the famous ODTUG's Kaleidoscope conference will be held that month, but also two events in Europe!
The first one is on Tuesday, June 15 in Dublin. CampusIT organizes a free (!) one day APEX event, packed with good sessions from Dimitri Gielis from Sumneva, Hilary Farell and Barry McGillin from Oracle and Jan Navratil from CampusIT (and I'll do a session myself). You can register using this link.
Later that week, on Thursday, June 17, the first official OBUG APEX SIG event is planned. The location will be conveniently located for all attendees from Belgium, The Netherlands and Luxembourg, somewhere in or around Antwerp. Also this event is jam packed with sessions, all aimed at APEX 4.0. Patrick Wolf, Dimitri Gielis, Iloon Ellen and myself will do a session on one (or more) of the many APEX 4.0 new features. There are still two presentation slots open, so if you do have a good APEX 4.0 idea and want to present on this great event, send a mail with the title and abstract to Dimitri or myself and you might join the stage! Registration has just opened - free for OBUG members! -, so follow this link.
Hope to see you at one (or both?) of these events!

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…

APEX 5 New Static File Features

In APEX 4 you could upload files - like CSS files, JavaScript files, Images and whatever else you like - into the APEX Repository. When you navigate to Shared Components, there is a Files section that offers three different options:
CSS Files are always uploaded (and changed !) for the whole Workspace. For Images and Static Files (usually JavaScript) you could choose whether they should be available for the whole Workspace or for a specific Application only. And if you had a lot of files - e.g. a lot of images - then you had to go through the upload process one-by-one. But that's usually a one time only thing. If you make changes to the CSS and JavaScript files - and that's a continuous process in development - then you had to delete the existing file and upload the new one. Over and over again. And meanwhile fighting the cache of the webserver and your browser.  And another irritating issue: You couldn't use relative references in your CSS or JavaScript files as they just…

Using LDAP for Authentication and Authorization within APEX

One of my current customers would like to use their LDAP (Microsoft Active Directory) server for authentication and authorization of APEX applications. Of course we tried to set up a standard LDAP Authenication that's available within APEX. But we couldn't get that to work. Maybe it has to do with the fact that the client stored their Users within Groups within Groups within .... . Or maybe it doesn't do a full tree walk in the directory. Or maybe it is just because it is Microsoft - and not Oracle Internet Directory (OID). So we moved to a custom Authentication using the DBMS_LDAP functions (and some examples from the Pro Oracle Application Express book and Tim Hall - a.k.a. Oracle Base).

One of the issues we encountered that we wanted to use the user's login name, like "jdoe" and not his full name ("John Doe"). And the login name is stored in the "sAMAccountName" attribute. But authenticating using just "jdoe" didn't work. …
