Upgrade to Apex 4.2 - apex.widget.tabular' is null or not an object

After upgrading to Apex 4.2 the following error occurrs when loading a page that contains a Group Select List [Plug-in]:
*'apex.widget.tabular' is null or not an object*
The error message appears to be related to a Group Select List [Plug-in] item with the following assigned List of Values attributes(options):
Display Null Value: Yes
Null Display Value: -
Null Return Value: NULL
Note: The application requires a NULL option to be displayed in the list of values (display = '-', value = null). This works fine in Apex 4.1...
Removing the above values does eliminate the error message. However entering any value into the Null Display Value and Null Return Value item attributes causes the error message to reappear.
Is this a known Group Select List [Plug-in] issue/bug? Any ideas on how to work around this issue would be greatly appreciated.
Thx

Hi,
http://apex.oracle.com/plugins contains an updated version of the Group Selectlist plug-in (v1.1) which should fix your problem. Just import it into your application and you should be done.

Apex 4.1 IR: $.datepicker._curInst' is null or not an object

Funniest thing after upgrade from 4.0 to 4.1 - Getting page error on IR when trying to create filters:

And the problem solution:
Check your IR columns. The problem occurs when column without heading exists. I had one column with &npsp; heading. I renamed that column and now IR works fine.

I am unable to reproduce the issue from my side, since it is JavaScript issue, i would suggest to clear the browser cache, history, Temporary internet files and then try again.

APEX 4.0.2 Error on Master Detail Pages - 'length' is null or not an object

Greetings,
We just upgraded to APEX 4.0.2.00.07 this past weekend. Now a JavaScript error occurs when Master Detail pages are opened in IE 8. The error is - 'length' is null or not an object. I do not have a page item named length on any of these pages.
The error does not occur in Chrome or Firefox, but the Add button on the detail portion of the page simply doesn't work.
The page works when creating the master portion of the page. After the master row is created the region to add detail rows appears and the error occurs. So, the error appears to be with that part of the page.
We use an Inactive Date column to soft delete rows in the detail portion of the page, so the detail regions have a date column, just in case this column is the problem.
Does anyone have an idea what the problem might be?
Thanks, Tony

I too had this same problem and determined that the problem was due to a missing underscore character between the literal "report" and the report Id in the report template.
I guess some themes include this underscore and some don't.
I had to debug the apex_4.0.js to determine this - not easy as it's not nicely formatted.
It only seems to stop Pagination working in an Updatable Tabular Form Report.
Edit the Report Template. Go to the "Before Rows" region and edit the Before Rows text box. Locate where it defines the report id and insert an underscore between report#REGION_ID#
Previous
<div id="report#REGION_ID#">
Fixed
<div id="report_#REGION_ID#">

About upgrade from previous version of Apex to a higher version-XE

Hi,
We are using Apex based on database 10g Xe, but we found that it is not easy to upgrade to a newer version of apex, becuase we have to install the full version at every realease of a new apex.
We cannot access Metalink to find the patchsets for upgrade, will you make it easier for upgrading the xe, like, put a upgrade file in the full realease?
Or enable downloading the upgrade patchset out of Metalink?
Is that possible?
Peter

Hi John & Arie,
Thanks for your kind answers, at currently we are not considered an upgrade, becuase our database is so small, and so little end users for my apex app, I am only running a very small, not much feature apex app, and only with cocurrent users 2, total users 5. We used the app almost one year, and if I expdp the schema I am using for work, it is only 4.5MB.
It is totally my personal stuff, I found it is very effiecient, becasue otherwise I have to do the samething with MS Excel, my small app, though humble, but much better than Excel.
I may consider an upgrade if I made a success step with Bill of Material and the warehouse management, in the future, currenlty I still don't have to gut/skill to do so, I am struggling with PL/SQL now, the basic stuff.
So, I think any upgrade will be too expensive for us, and I even dreamed the printing with BI, but that is just too expensive for my humble app.
yeah, though without access of Metalink, we can still find some very good workarounds, thanks to the apex/Oracle team, and guys/girls like you that offer kind of free services at this forum.
I just did the upgrade with the full installation, I drop everything and reloaded them after upgrading.
Took me around 1.5 hours to do so.
Cheers,
Peter

Upgrade htmldb 2.0 to apex 3.0

I have the database where originally was installed htmldb 1.6 and after successfully upgrade to 2.0. After I was trying upgrade to 2.2.1, the upgrade was successfully, but all application were messed up, ever uninstall didn't help. I did import htmldb schemas from export dump file, before started installation of Apex 2...2.1.
This time I did export/import htmldb schemas and my schemas to another test database, Run installation Apex 3.0. It has a lot of errors in the table FLOWS_030000.WWV_FLOW_UPGRADE_PROGRESS, It is actually 577 records in this table. I was testing applications, they looks okay.
Do you think I should go and install Apex 3.0 in my main database?
Can I experience later some problems?
Thanks MB

Mary,
It is difficult for me to understand the whole situation from your description. Let us go one statement at a time:
I have the database where originally was installed htmldb 1.6 and after successfully upgrade to 2.0.
So this statement, or situation, is not related to the current situation, is that right? All was well with your 2.0 instance?
After I was trying upgrade to 2.2.1, the upgrade was successfully, but all application were messed up, ever uninstall didn't help.
I have no idea what you mean.
I did import htmldb schemas from export dump file, before started installation of Apex 2...2.1.
I don't understand. You imported which schemas that you got from where? And why?
This time I did export/import htmldb schemas and my schemas to another test database, Run installation Apex 3.0.
Export/import of the Application Express schemas is not like installing the product. SYS grants will be missing.
It has a lot of errors in the table FLOWS_030000.WWV_FLOW_UPGRADE_PROGRESS, It is actually 577 records in this table. I was testing applications, they looks okay.
Do you think I should go and install Apex 3.0 in my main database?
Can I experience later some problems?
You need to refine the process until there are no errors.

APEX Listener with APEX 3.0 on 11gR2

Yes, I am crazy.
We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.
The APEX listener appears to be more than just a Java PL/SQL gateway.
Is there a minimum version of APEX the APEX Listener supports?
Interested in pointers!
Rob

Hi Rob,
Yes, I am crazy.Why would that be? ;)
We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.APEX 3.0 is supprted by EPG. See the [url http://docs.oracle.com/cd/B32472_01/doc/install.300/b32468/post_inst.htm#CHDBEJDA]APEX 3.0 Installation Guide for details.
APEX Listener is capable of hosting APEX 3.0 as well, though APEX 3.0 wasn't supported anymore when APEX Listener was initially released. The current APEX release at that time was 4.0, so this would be the first version to be known as really stable, whereas you won't get any support for older releases anymore. From personal experience I know that there are now issues with APEX 3.1 and APEX Listener, so it'll probably also work with 3.0.
Concerning your database release, the minimum for APEX Listener is 10.2.0.3, so you're definetly safe on that part, though I'd recommend to upgrade as regular support for 10.2 databases ended.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.This indicates that your APEX would actually be a 3.1 and you should update you images directory.
The APEX listener appears to be more than just a Java PL/SQL gateway.It is, but this has nothing to do with your 3.1 JS files, if this is why you stated this.
Is there a minimum version of APEX the APEX Listener supports?As mentioned above, 4.0 would be a safe approach, but 3.1 will definetly work, 3.0 probably will as well. I'd recommend you find out which APEX version is actually installed on your database before you consider any upgrade operations. Run the following query as privileged user:
SELECT comp_name, version, status
FROM dba_registry
WHERE comp_id = 'APEX';-Udo

Apex Listener and Apex .3.2.1

Does Apex Listener work with Apex 3.2.1? May be I missed it, I can't find any info in the document.

Short question, short answer: It does.
The documentation for the APEX Listener doesn't refer to any special APEX version. The fact that the APEX documents only name the APEX Listener from APEX 4.0 onwards is due to the APEX Listener not being available before that release.
We have it running with APEX instances from 3.1 onwards, but I assume you could use it even for older versions.

Can I use my APEX application without APEX?

Can I use my APEX application without APEX?
Kostya

Hi Kostya,
Any chance you can elaborate a bit more on what you are trying to do? By definition, you cannot run an APEX application, outside of APEX, but it is only HTML and Javascript at the end of the day, with some clever logic behind it. No reason why you couldn't create your own HTML pages that perform similar tasks.
Hope this helps,

(2) If different, will examples on OTN APEX Studio run in APEX 3.0 envrionment?
Thanks,

Upgraded to the latest version of FireFox After restarting I could not browse? Also how do I export bookmarks?

The browser acts as though it is connecting to the page, yet without giving any sort of error, it shows up as blank. Just pure blank with the address on the URL bar, and (I forget the name sorry) the little page icon that often appears next to the address is a blank page, the name of the website also does not load on the top bar.
I restarted my computer, but this didn't work either. Not even the "What's New" page of FF that automatically comes up after an update wouldn't load.
I have no idea WTF this is about but I have no way of browsing now. I'm on my PC since I have no other way of browsing on my laptop (I've gotten rid of IE)
I just don't know what happened because I didn't do ANYTHING ELSE! I downloaded the update, installed and then restarted FF.
If this is a general problem then I want to uninstall FF completely and revert back to the previous version- but I did this before on an old comp that didn't handle the upgrade too well, and I lost my bookmarks.
How can I save my bookmarks?
Thank you!
PS- I'm posting this from my PC, and the upgrade has also been done on this computer, however I'm not experiencing any problems here.
I also posted this question on Yahoo! Answers and someone said this:
This is currently happening to me too, and I eagerly emailed Mozilla and they replied saying,
''Thank you for the message you sent to our team. We are currently facing huge problems with our update managers and several issues have risen around the world about updating failures. We hope to get it fixed as soon as possible and we hope you understand that we are trying our best to get it back up and running''
So, I advice you to use Chrome or Opera while Firefox updates their problems.
Honestly I don't know what the hell to do. Like I said above, I removed InternetExplorer from my laptop and have no other browser.

See;
* http://kb.mozillazine.org/Backing_up_and_restoring_bookmarks_-_Firefox
* http://kb.mozillazine.org/Profile_backup
Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

After upgrading to OS 10.9.1 Aperature 3.2.3 does not work and I'm not able to download new version of Aperature.

After upgrading to OS 10.9.1 Aperature 3.2.3 does not work and I have not been able to download upgrade of Aperature?

Is Aperture installed in the "Application"s folder and simply named Aperture? If not, move it back to "Applications". Did you buy Aperture from the App Store or as a boxed Retail version?
Relaunch the App Store and sign in with your Apple ID (in the Store menu). Reload the "Purchased" page of the App Store. Do see Aperture on the Purchased tab or perhaps the "Accept" portion of the "Purchased" page? If in the "Accept" portion, accept it to your AppleID and install it. Else look again at the Update page.
For some forum members the update did only appear until after setting the primary system language to English and rebooting the Mac. This bug is supposed to have been fixed with the update to 10.9.1, but try it, if all else should fail.
