JPA Metadata issue/ Weird Column error or bug in openjpa ...?

Hi All,
I am getting the following exception when using openjpa in my project.
The line of code that throws the error is also mentioned
The latter error shows a column mismatch error which i am not sure is correct since the db i am using is Oracle 10g and the datatypes for the column are varchar2.
         BcsPort bcsPort=em.find(BcsPort .class, port);   //Error after this call.

Any inputs on this highly appraciated

That link seems to deal with a bug relating to a one to many mapping. I don't see anywhere in your post that you are dealing with the same thing.
Actually i am using Many to One mapping as you can see from the code excerpt
BcsPort
@ManyToOne(optional=false, cascade=CascadeType.ALL, fetch=FetchType.EAGER)
@JoinColumn(name="ne",referencedColumnName="ne")
private BcsNe bcsNe;Why i posted the link was that it seems to throw the same weird column exception that i got and more googling revelead that it was indeed some issue between the way the oracle varchar2 field is being handled by openjpa.
so just needed to confirm if this was a widely faced issue and a possible fix to the same
Is there a particular reason why you are using openjpaActually it's been added recenlty to the system as before it was using normal JDBC Code...
In stead of the persistence provider shipped with your JEE container anyway?Do you mean that i should use the Oracle Weblogic 10.3 persistence provider...?
kindly suggest...

4.2.1 Does Not Fix" Crash-on-screen saver" bug or metadata issues

ATV2 crashes as soon as it goes to screen saver. 4.2.1 does not fix this. WTC?
You have to set screen saver to "Never" to prevent crashing.
No one checks these things?

Repository Configuration Metadata issue for OBIEE11g

Hi,
I am having an issue while using RCU to created BI schema.
On database connection details wizard, after giving all details, on checking prerequisites, on Initializing repository configuration metadata, it gives an error:
The version 11.2.0.1.0 of the database that you are using is not a supported version or
The specified user may not have sufficient privileges to perform this operation. User should have sysdba or dba privileges.
But I successfully reached at Map Tablespaces step on previous attempt.
Only thing I change before re-running the RCU is, delete unwanted tablespaces.
On db connection details I am using user SYS and role SYSDBA.
Please, can anyone suggest to solve this.

Some where you might have to rename the PREFIX from DEV to DEV1 or some thing else.

Metadata Issue?

I submitted my book Friday morning. Checking yestderday, I see this.
"Metadata Issue. There is an issue with the metadata. Contact us after you have verified and redelivered the metadata."
Trouble is, I can't see anything wrong with the metadata. The blanks are all filled in. Has anyone else seen this? I did a search here and it seems to indicate that Apple won't be able to tell me what the problem is. Any hints or pointers would be greatly appreciated.

It would be easy to verify for iTunes Producer whether the title in the metadata matches the title in the book. Sadly, it doesn't do that.
"Metadata Issue. There is an issue with the metadata. Contact us after you have verified and redelivered the metadata."
Singularly useful error message. The author gets to play the guessing game. Why not just say "The title in the metadata doesn't match the title of the book"?
I have the same problem with many of my submitted ebooks.
All I can suggest is to diligently go through each field of metadata, checking that it meets the requirements set up in the publisher guide and that the metadata is consistent with the book you submitted.

List metadata navigation and columns filters not working.

Hi
I'm having an issue with SP 2013 whereby if I apply a filter through metadata navigation subsequent columns filters don't get applied.
Here I've applied a filter through the navigation and it applies the filter successfully to the documents in the library
If I now apply a column filter by content type and select the value Promotion Calendar, I get the following
It appears the filter is selected and I can indeed see the filter applied via the dropdown but it doesn't apply the filter to the list view. I've confirmed this also on another environment using different columns for the metadata navigation.
The environments are patched to Dec 2013 CU.
Thanks

Hi
Matt Williams3 ,
The scenario is be default that Managed Metadata navigation tree in document libraries does not allow further filtering on other columns.
For a workaround, you can use Key Filters instead.
For more information, you can refer to the blogs:

Endless "Stream Overlap" Error Loop Bug Crashes Encore

Endless "Stream Overlap" Error Loop Bug Crashes Encore.
This is the 4 th time I have reproduced the bug.
I burn a Disk image .. and upon completion the "Disk Info" resets to zero bytes under the Build Menu and when checking the Timelines Window the Dialog Box pops up with the "Stream Overlap" Error.
Has anyone else had this issue?
I have read other forum post .. and there is nothing relevant.
I had to rebuild the project twice from scratch.
I'm waiting for my Master Collection 5.5 .. maybe it is fixed in it.

NOTE: There is a issue with Premiere Pro Dynamically Linking with After Effects with file corrupting I am experiencing as well.
Someone offered a solution to rename my files to just words. ( No numbers or other characters )
It still crashes .. and there is still file corruption ... but a "Linked Composition" can be found by "Edit Original" .. whereas it was not found before I changed the filename.
This is a beginning to find the source of the nested bugs.
I am wondering if this filesystem problem is core to the "Stream Overlap" problem noted here.
I have have not reached tech support on the Encore side of this problems as of yet.
This type of file system also has a terrible result for dated files:
On the Mac ( Standard Finder ) :
2011.1.1
2011.1.2
2011.1.9
2011.1.10
2011.1.11
is treated in Adobe Encore as well as other Adobe Suite Master Collection Apps ( On the Mac Platform ) as:
2011.1.1
2011.1.10
2011.1.11
2011.1.2
2011.1.9
This make NO logical sense at all .. and must be some old DOS filesystem?
Timecode
Datestamp
Numbered Outlines
Are all very important ways to organize files / video.
I am surprised that Adobe did not address this years ago.
I have had two Adobe users mention a file system problem that has been known.
Maybe it is the cause of my issues? ... Adobe is mixing two incompatible filesystems on a root level on the Mac platform only. ( Doesn't work with the Mac Finder? )

Firefox 14.0.1 has a spell checking error./ bug in the code

I just had all my machines update to 14.0.1 (WIN XP SP3)
I had a clean boot right before the update occurred.
This is the first time I had used this version on this machine.
When the program came up, I had no access to the spell checker at all. Nothing I did could change this (checking and un-checking the feature in the right click menu.
So, I selected the option of restarting the browser in "SAFE MODE" with no add-ons. There was no change at all (still no spell checking)
So, I went to this site, made an account, activated the count (this entire time FIREFOX had no spell checking) and I created a report.
I was most of the way done writing the report when suddenly the spell checking started to work. I made no changes to the settings, when suddenly I had spell checking working.
This means there is an intermittent error;p often the hardest to find from my 20+ years of programming experience (Senior IT contractor)..
So, have find finding this one. Intermittent bugs are the hardest to track, and tend to come from issues like scope issues, settings stored in files/registry, overly convoluted code (like a rush job that isn't fully understood & was just hammered on until it seemed to work). From my experience it often happens in the last steps of finishing a release - accidentally introducing a bug into what was a working section of code (unexpected ramification are a suspect) into a previously working program piece of a program.

Hi BarleySinger and thanks for reporting us this issue.
Yes. Intermitent bugs are really difficult to track and solve, so please try to do this things:
* Try to reset Firefox so all settings that may be creating this problems will be removed.
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
Did this fix your problems? Please report back to us!
* Try to perform a antivirus scan on your computer so you check you have no malware.
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try some of the following programs to scan for malware:
* [http://www.malwarebytes.org/mbam.php MalwareBytes' Anti-Malware]
* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
* [http://windows.microsoft.com/MSE Microsoft Security Essentials] (A good permanent anti-virus if you don't already have one)
Further information can be found in the [[Troubleshoot Firefox issues caused by malware]] article.
Did this fix your problems? Please report back to us!
* Send us troubleshooting information.
In order to be able to find the correct solution to your problem, we require some more non-personal information from you. Please do the following:
*Click the Firefox button at the top left, then click the ''Help'' menu and select ''Troubleshooting information'' from the submenu. If you don't have a Firefox button, click the Help menu at the top and select ''Troubleshooting information'' from the menu.
Now, a new tab containing your troubleshooting information should open.
*At the top of the page, you should see a button that says "Copy all to clipboard''. Click it.
*Now, go back to your forum post and click inside the reply box. Press Ctrl+V to paste all the information you copied into the forum post.
If you need further information about the Troubleshooting information page, please read the article [[Using the Troubleshooting Information page]].
Thanks in advance for your help!
* Check the issue is still reproducing intermitently, and it was not an isolated problem (Maybe Firefox was still preparing the spell checker).

Log Message:
Fix for error reporting bug. The bug was caused by a warning being
reported during one compilation and then an error being reported in
a following compilation. Due to the warning, the Source's logger
was disconnected instead of being nulled out during the first
compilation. Then in the second compilation, we weren't reassigning
the logger, so the disconnected logger was being left in place. As
a result, it was throwing off expected error counts and caused an
assert to fire.
QE notes: There is probably an easier way to reproduce the assertion
          that George hit without having to create multiple projects
          and without having to manually copy SWC's around. I didn't
          realize this until I had a fix, though. One key aspect that
          George didn't note and might not have realized, is that the
          variable needs to cause a warning, so leaving off a
          namespace works, but making it public, private, etc doesn't.

Issue with SRDemo error handling

Hi All,
Glad the forums are back up and running. In debugging some error-handling issues in our own application, I found an issue in the error handling code of SRDemo. I thought I'd post the issue here, as many of us (myself included) use some SRDemo code as the basis for our own applications.
The issue can be found in the oracle.srdemo.view.frameworkExt.SRDemoPageLifecycle class, specifically in the translateExceptionToFacesErrors method. I'll show the code that has the issue first, and explain the issue afterwards:
        if (numAttr > 0) {
            Iterator i = attributeErrors.keySet().iterator();
            while (i.hasNext()) {
                String attrNameKey = (String)i.next();
                 * Only add the error to show to the user if it was related
                 * to a field they can see on the screen. We accomplish this
                 * by checking whether there is a control binding in the current
                 * binding container by the same name as the attribute with
                 * the related exception that was reported.
                ControlBinding cb =
                    ADFUtils.findControlBinding(bc, attrNameKey);
                if (cb != null) {
                    String msg = (String)attributeErrors.get(attrNameKey);
                    if (cb instanceof JUCtrlAttrsBinding) {
                        attrNameKey = ((JUCtrlAttrsBinding)cb).getLabel();
                    JSFUtils.addFacesErrorMessage(attrNameKey, msg);
            }Now, this bit of code attempts to be "smart" and only show error messages relating to attributes if those attributes are in fact displayed on the screen. It does so by using a utility method to find a control binding for the attribute name. There are two issues with this code, one obvious, and one that is a bit more subtle.
The obvious issue: if there is a binding in the page definition, it doesn't necessarily mean that the attribute is shown on the screen. It's a good approximation, but not exact.
The other issue is more subtle, and led to errors being "eaten," or not shown, in our application. The issue comes if you are using an af:table to display and update your data. In that case, the findControlBinding will not find anything for that attribute, since the attribute is contained within a table binding.
Just posting this as a word to the wary.
Best,
john

somehow, this message got in the wrong thread....
Hi Frank,
Yes, I simply scripted it out this way to contrast the behaviour if the first attribute was read-only vs not read-only. I found the issue on a page in our app that was simply drag-and-drop the VO from the data control on the page.
It's quite annoying, because our particular use case that hit this error is a "save" button on the page. If the commit operation doesn't return any errors (and it doesn't in this use case!), we add a JSF message saying "save successful" - then the attribute errors are further added later in the page lifecycle, so we get 3 messages: "Save successful" and "Fix this error" and "Tried to set read-only attribute" - quite confusing to the end-user when the only message they should see is "fix this error."
At any rate, the fix is to simply re-order the attributes in the page definition - that doesn't affect the UI at all, other than to fix this issue.
John
it was supposed to be something like:
Hi Frank,
Thanks for the reply. I was simply posting this here so that people who use the SRDemo application techniques as a basis for developing the same functionality in their own apps (like me) can be aware of the issue, and avoid lots of head-scratching to figure out "what happened to the error message?"

Adobe reader issues windows 8 Error 1935.An error occurred during the installation of assembly compo

calling was on the phone for 20 minutes and no one answered. I was not able
to re install windows. Contacted Asus from another computer and they were
not able to help me reinstall windows They had asked me to ship my computer
back to them, due to them not being able to resolve the issue and help me
reinstall windows. I luckily had a backup on my external hard drive and was
able to reinstall windows 8. Spent over an hour and half trying to fix
that. Here I am still not able to install adobe reader. I was very unhappy
with what I was told to do and it gave me this issue.

Looks like the presentation column got Alias before your BMM changes, so in your case renaming logical column and deleting alias is not good to go.

Thanks, dzedward,
I posted a reply with quite some effort in it, but it is
dissapeared after pressing the reply button. what I as explaining
was that I use an attached sound and so streaming is not an issue.
Please look at the few lines of code I use in my demo (please use
the link above for the fla with the WAV):
audioClock=new Sound(createEmptyMovieClip("sound1",1));
audioClock.attachSound("theSync");
audioClock.setVolume(90);
stop();
//When playing a swf (in most cases) the audio clock is on
every 46.4399093 ms.
//A onSoundComplete function only starts ON a clock puls!
That explains "gaps"
//when people complain working with audio loops in Flash.
//The audio sample used in this test has a 200 ms duration.
It can't be shorter.
//So it is started 25 ms from the end. When the sample is at
the end, the flash player
//pauses for 46.4399093 minus 25 ms, and starts the audio
sample from the same point
//again ( that is at the next clock puls). That's fine for
hearing audio clock and
//this test:
audioClock.start(0.175,1);
audioClock.onSoundComplete = function() {
audioClock.start(0.175,1);

Not a group by column error message - cursor sharing

Hi,
Our database is Oracle 11g.
We faced problems about some sql's. These sql's were running in Oracle 10g.
Our sql statements are like the below query:
SELECT COLUMN_A,COLUMN_B,COLUMN_C,
TO_CHAR(OPERATION_DATE,'DD/MM/YYYYY'), CUSTOMER_NAME || '-' || CUSTOMER_SURNAME,
DECODE (IS_MANAGER, 0, ' Manager', 'Employee')
SUM(TOTAL), SUM(AMOUNT), AVG(SALARY),
FROM TABLES
GROUP BY COLUMN_A,COLUMN_B,COLUMN_C,
TO_CHAR(OPERATION_DATE,'DD/MM/YYYYY'), CUSTOMER_NAME || '-' || CUSTOMER_SURNAME,
DECODE (IS_MANAGER, 0, ' Manager', 'Employee')
ORDER BY COLUMN_A,COLUMN_B,COLUMN_C,
TO_CHAR(OPERATION_DATE,'DD/MM/YYYYY'), CUSTOMER_NAME || '-' || CUSTOMER_SURNAME,
DECODE (IS_MANAGER, 0, ' Manager', 'Employee')
When we remove order by or when we disabled cursor sharing, problem is fixed.
I think that sql looks correct. Why we are taking not a group by column error message?
How can we fix this problem without changing querys( we have other reports which gives same error message) or disabling cursor sharing?
Thank you, Bye

Dear,
SELECT   column_a
        ,column_b
        ,column_c

        ,customer_name || '-' || customer_surname
        ,DECODE (is_manager, 0, ' Manager', 'Employee')
        ,SUM (total)
        ,SUM (amount)
        ,AVG (salary)
    FROM TABLES
GROUP BY column_a,
         column_b,
         column_c,
         TO_CHAR (operation_date, 'DD/MM/YYYYY'),
         customer_name || '-' || customer_surname,
         DECODE (is_manager, 0, ' Manager', 'Employee')
ORDER BY column_a,
         column_b,
         column_c,
         TO_CHAR (operation_date, 'DD/MM/YYYYY'),
         customer_name || '-' || customer_surname,
         DECODE (is_manager, 0, ' Manager', 'Employee')Here you are grouping by
DECODE (is_manager, 0, ' Manager', 'Employee')What does represent the is_manager? it is a function ? it might be that you hit one of the group by restriction such as select are not allowed into the group by clause
