APEX Connect 8th and 9th of June 2015 in Duesseldorf Germany

Tue, 2014-10-21 03:34
APEX Connect is the first big APEX event in Germany and will be taking place in Duesseldorf on 8th and 9th of June 2015. You can still apply for a presentation using this link. I will be there with a presentation on APEX Plugins. As far as I know a couple of international guests are expected to be there as well. This event will for sure be interesting and informative so you should think about participating. Düsseldorf is close to Belgium and Holland so I think that we will have quite a lot of visitors from those counties as well. It just comes to my mind that the presentation should be in English. So, you should make sure to book your ticket, hotel and travel in time.

XML Parsing Error: no element found Location: ...

Tue, 2014-09-16 00:07
I am just working on an application which is supposed to be exposed to public users. I created a simple ajax process there which gets a value of an application element and does something based on the value. While calling the on demand process I am getting this error while not authenticated:

XML Parsing Error: no element found Location: moz-nullprincipal:{6492ed13-2b81-4989-938c-7c19121f419a} Line Number 1, Column 1:

After searching for this error in combination with APEX I found my old thread from 2012 which basically wasn't answered:

After investigating what is happening there I noticed that the on demand process I created is set to "must not be public user" in the authorization section. Obviously APEX does that by default for the on demand processes. Running the ajax call would not find the "element" which is the actual process.

APEX - Default Branch on Submit

Wed, 2014-09-10 06:55
Yesterday I spent two hours on debugging one of my applications and searching for an answer. Of course, the problem was caused by myself. Here is what happened:

I copied a page and deleted the region including buttons and items using the Cascade to Delete Buttons option.

Then I created a form and had there a process on submit to upload files in my table. Everything was working fine except the fact that after the process the page would show up empty having the funny



Looking at the page I couldn't see anything what would point to the actual problem. The process was there and it was running and the branch was there. Only after a while I looked into the branching and saw there that it was conditional - firing when the deleted button was pressed.

Then it came to my mind that this wasn't the first time I had this problem. I think this is a bug and it has to do with the file browse item. I expected the page to redirect after submit since this feature is there since 4.0. However, it didn't. This issue seems to be fixed in 5.0.

And one more thing to add: It does make sense to create conditional branches but it doesn't make sense to create unconditional ones. The feature of creating unconditional branches to the actual page, where the branch resides, should be removed completely.

You can see it in "action" here

Set Focus on Added Row Tabular

Tue, 2014-08-05 09:19
This sounds quite simple:

"I would like to set focus on the new added row in my tabular form."

In the following example, you can se how to acomplish that.

Cascading Shuttle - Keep Selected Values

Tue, 2014-08-05 06:14
There are probably a several good ways to solve the following problem:

    1. you have a simple select list which cascades a shuttle element
    2. you select something and the shuttle is populated
    3. after that, you pick a value in the shuttle and move it to the rigt side
    4. then you change the select list again
    5. the values you selected in your shuttle are now lost

This example shows how this can be done. This question apears in the APEX Forum from time to time and I decided to provide one simple solution for it.

jQuery - loop through a Tabular Form

Thu, 2014-07-31 07:48
This question is one of the frequently asked questions - "How do I loop through a tabular form using a dynamic action?". This example shows how to loop through a tabular form and set the values for each row to what ever you want. Using apex_application.g_fxx array is not an option for onload processes or dynamic actions. It can only be used in an on submit process. Using jQuery in a simple loop it is possible to read / set any of the values in any column. Try it out.

OTN APEX Forum again

Thu, 2014-07-31 04:02
The OTN Forum is not available (again). This usefull but constantly changing forum now gives me the following message:

I am not sure why they are using jive for that. Maybe APEX would be a better solution.

OTN APEX Forum Link

Mon, 2014-07-21 00:33
Oracle again changed the layout of the forum. For me, the old link didn't work any more. In case you have problems finding it, here is the new link:

If you go to the forum and search for example for "APEX" or "Application Exp", you will see no results. Typing in "Application Ex" will find "Application Express".

Each of the found links will have a funny description saying:

"An error occurred processing your request. If this problem persists, please contact the webmaster or administrator of this site."

:) So, it seems there are now even more bugs than before.

Probably, the intention to change the forum wasn't bad. However, once you manage to open it you will see a lot of information you don't need (or at least not all of the time). The real content is somewhere underneath and needs scrolling like in Facebook (oh, how I hate that site). And the worst thing is that you can see only ten threads per page - if you want to see more then click and scroll again. For those interested in helping others this is making things much more complicated.

One positive thing though. :) My name suddenly appears in the top list of the participants in the forum. The list isn't reduced to the top five but it now shows the top six. Top six is obviously the new top five. ;)
