Moscone South Room 309, a really big (300 cap.) room with a stage and a giant screen. There were about 40 people attending my session and it went fairly well. I wasn't too nervous and I ended the presentation in 50 minutes, including some Q&A. After the session some people came up in front to ask some extra information and I also got some positive feedback from Francis and Raj. Most questions where related to Can I have to code? So here we go: For the explanation of the Drag & Drop feature I showed you can also take a look at Rutgers blog. That part of the application is also available apex.oracle.com. If you use Firefox and Firebug it's easy to see the javascript that does all the work. If you want to have it in a single file, please leave a comment using your e-mail address or send me an e-mail directly (look at LinkedIn or my complete profile). I promise I will upload the generic LOV solution to apex.oracle.com next week - I'll write a post about is as well.
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 ...

I saw this demo before, but it's still slicker than grease! :-)
