Good Blog Bad Blog

Sat, 2014-12-06 03:29
Just checked if the http://www.odtug.com/apex is available again and it is. It seems the people there are filtering blogs because I don't see my blog post from yesterday appearing there and I don't understand why. Is that just because I said that the old blog listing was much better? Or this is just another technical problem they have? Am I going to be removed from that blog listing forever if I continue saying things which they may not like?

You shouldn't think this happens only to you

Fri, 2014-12-05 03:17
Since several hours I am getting this while trying to access all blogs at http://www.odtug.com/apex. It seems that this list has a lots of problems listing all the relevant APEX blogs. The previous version from Dimitri was so much better and user friendly.

Value Placeholder

Tue, 2014-11-11 05:46
Did you know that you can use Value Placeholder in your page items to display hints for the users? This is a quite neat feature you can implement without using different plugins for displaying hints. It will also work with the APEX ampersand substitution strings like

&P1_ITEM.

Here is how it looks like. Be carefull with this. It will work only for the browsers supporting HTML5.

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:

https://community.oracle.com/thread/2444115?start=0&tstart=0

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

wwv_flow.accept

message.



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
