Page protection violation Error

Hi guys,
I have two tabs in a tabset and when I try to click second tab from first tab it gives below exception.
"Page protection violation: This may be caused by manual alteration of protected page items. "
As the exception said I change an item value on page1 from page2 by using link-> f?p=10:1:690313625705501::::P1_SELECTED_OBJ:OBJ_VALUE (P1_SELECTED_OBJ is the item on page 1)
How can I fix this problem , do you have any idea? I found some topics related with same error but they are related with upgrade of Apex.
Apex Version : 4.1.1.00.23
Thanks.

This might be because you are changing the protected items value using JavaScript.
You can edit the apex item > set the protected to No

Page protection violation

Hi ,
I have a classic report whose source is being framed dynamically. Since the number of records are more, it takes more time to render the report. I'am getting page protection violation error when I press any button while the report is rendering. Please help me to have a mask on the page until the report renders completely.
Regards,
sasi

Hi Hari,
Thanks for your reply.I have already tried that plugin.It works fine but mask is going off as soon the page loads.It doesn't stays untill the report renders completly. Its not identifying the report is being rendered or not.
Thanks,

First, please don't post questions/issues and start with "Very Urgent". If you have an "urgent" issue I recommend you contact Oracle Support. Second, if your issue is so urgent, I further recommend that you read this (url below) before going any further.

Finally, I am going to guess and say that you are having problems with Oracle Apex version 4.2. If I am correct, I will tell you that this forum space is for Oracle Forms. APEX questions should be posted here (below). However, if you plan to post the same issue there, please consider reading the blog I mentioned above and follow its recommendations before posting anywhere else.

Hi Mike,
This error may be because of of some hidden item you have created and made it protected.
Now while navigating you are updating that hidden item.
Kindly check hidden items on your pages.

Page protection violation: This may be caused by submitting a page...

Hi all,
We are migrating from ApEx 3.2 to 4.2, and from 10 to 11g.
I am now getting this message when I click on a Flot pie graph on my page (runs some javascript: DoSubmit("PIE_CLICK"); ).
What does it mean? I have already looked at Page protection violation on APEX 4.1.1.00.23
Page protection violation: This may be caused by submitting a page that had not yet finished loading or by manual alteration of protected page items. For further assistance, please contact the application administrator.

I have now managed to fix this problem which occurred again on another page.
Luckily, this page was a "copy" of another page which still worked, so all I had to do was compare the two pages. I discovered the difference was that they were using subtly different page templates.
I realised it was the old #FORM_OPEN#, #FORM_CLOSE# problem, and I changed the two #FORM_X# locations in the faulty template to be "tighter" around the #REGION_X#s. I had previously put the FORMs around all my #REGION_#s, even non-input ones, but maybe I had an unmatching div or something, and it couldn't find the FORM_CLOSE.
So now it works!
Sorry, I can't put up the faulty template, because I can't remember where the FORMs were when it was broken (and I'm a bit of an amateur at page templates, so they look really bad)!

Session State Protection Violation error

I am developing my first Apex application. I have this page which has been running fine until I made some changes. The error I get is the following:
-----Error message:
Session state protection violation. This may be caused by manual alteration of a URL containing a checksum or by using a link with an incorrect or missing checksum. If you are unsure what caused this error, please contact the application administrator for assistance.
--End of error message.
This happens Whenever the page is submitted for process, e.g. when I select from a "LOV with Submit" item or when I click the "Save Changes" button. It is fine if the button redirects to another page. Using Debug, I saw that the error occurs right after "Fetch page attributes" and before "Fetch session state from database".
About the changes I made before this error first surfaced: nothing to do with session state protection and nothing I can think of that is related to session state protection. In fact, I did not specify any session state protection at any level at this stage. That is, all pages and items are unrestricted. I did add a javascript to the page which is invoked onChange of an item to update another item. I made the same changes (except for the Javascript) to another similar page which is still running fine.
I tried logging out of Apex (I am using OracleXE) and getting back on, the error still persists. I even shut down and restart the Apex database to no avail.
Can anyone point me to where it might be the cause of this problem? Thank your help and/or suggestions in advance.

Scott - I should have posted this question sooner! I wasted a whole day trying to figure this out. Thanks a lot, Scott. By the way, where can I find any documented known bugs in Apex?

Runtime error: Protection Violation

Hello,
I am having an issue running reports in Labware LIMS. Labware is using crystal runtime XI to generate its reports. Basically what is happening is I can run a few reports (anywhere from 2-7) then I will get an error that states:
runtime error: Protection Violation
It also writes to error.log which i will post an excerpt from that file as well.
The only way to continue running reports is to close out of Labware and start over.
My operating system is Windows Vista SP2 and we are using Labware 5
Please help!!!
Thanks,
Cody

You will have to contact Labware and ask them. As it is, we don't even know what CR SDK they are using...

Problem since upgrade to 2.0 "Error: Session state protection violation"

I've upgraded to 2.0. Everything fine except one particular page when I submit it I get "Error: Session state protection violation". I have read up about session state protection, and it is turned off in my application. There are no items, pages or URLs that have any session state protection. There is nothing particularly different about this screen when compared to other screens that work. What can be causing this?
Steve

Steve - Thanks for putting that test case out there. This is an odd bug. It happens when you apply the read-only attribute to a "Display as Text (does not save state)" item. Normally, these items are not HTML input items on the page (you see only the value rendered). However, because of a bug, applying the read-only attribute causes an INPUT item to be created. This leads to the problem that you saw -- when an item that should never be POSTed because it is: a) an application item, b) a page item that has the Session State Protection attribute "Restricted - May not be set from browser", or c) a page item of display type "Display as Text (does not save state)", is POSTed, the Session State Protection violation is detected and reported. These checks are performed whether the Session State Protection feature is enabled for the application or not. The reason for that is that checking for cases(a) and (c) is always legitimate and checking for case (b) is always necessary because the Restricted attribute for page items of qualifying display types is always in effect.
So the workaround in your case is not to use the read-only attribute for the display-only items. They are read-only anyway.
Thanks again for pointing this out.

Page Protect in RTF Template

I have a RTF template in which I have the following defined:
header text
start:body
body text 1
for each g_group
text table
end g_group
body text 2 **** Page protect this
end body
footer text
I would like to do something like a page protect on the "body text 2" part
because if the group is longer than 10 rows the "body text 2" goes over
onto the second page and looks strange when it is split in two parts.
Has anybody done this?
I tried using the normal word paragraph formatting but as soon as I put in
a break I get the following error:
org.xml.sax.SAXException: element xdofo:start is not supported yet.
Thanks
Ellen

This functionality is only supported for table cells. So you can wrap your body text in a table with a single row/column and no borders. Then you select the table and then select Table -> Table Properties from the menu bar. Select the row tab and uncheck the checkbox:
[ ] Allow row to break across page
That should do the trick. Let me know, if it works for you.

Access Violation error with Diadem 2011

I've started using Diadem 2011, and have run into an Access Violation error when loading some of my existing reports. I've created a simple example which shows what's happening:
I've created a simple Bar plot:
If I change the left hand bar to be "Filled" instead of "Right Diagonal", Diadem throws up an access violation error. I've attached the TDM and TDR files used to create the graph. The error in the log file is:
139 Error while executing "" command
     Error type: ACCESS VIOLATION
     Error address: 0004F5E5
     Module nameIAdem.exe
Diadem: 11.0.3f4563 TDM
USI: 1.9.0f4551
DataFinder: 3.0.0f4556
(By the way, it would be great to be able to copy those version details directly from the About page!)
Attachments:
Data.zip ‏7 KB

I've tried this as administrator, and have exactly the same issues, so it doesn't appear to be a permissions problem. I've uninstalled and reinstalled DIAdem and everything's the same.
Here's another ZIP file with hopefully all of the required files. I've created the data files from scrathc several times, and see the same problem. One other thing I've just noticed is that it only occurs when filling the bars with the color Black, not blue or red or anything else.

With 3.6.12, Help menu item "For Internet Explorer Users" results in a "Page Not Found" error. Is this a known bug? Is it being addressed?

Clicking the 3.6.12 Help menu item "For Internet Explorers" item results in a "Page Not Found" error.
The URL of the resultant page is https://support.mozilla.com/en-US/kb/Windows%20start%20page?as=u
Is this a known bug, if so, is it being addressed? If so, someone needs to work faster.
If it is not a known bug, someone needs to get right on it - you want people to switch to Firefox and then there is this bug -- not a good way to impress Internet Explorer users.

Hi Claudio Roca,
I have encountered the same problem. Do you found the solution for this issue? I will much appreciated if you willing to share your solution and email to [email protected] Thank you so much.

Issue with INSERT INTO, throws primary key violation error even if the target table is empty

Hi,
I am running a simple
INSERT INTO Table 1 (column 1, column 2, ....., column n)
SELECT column 1, column 2, ....., column n FROM Table 2
Table 1 and Table 2 have same definition(schema).
Table 1 is empty and Table 2 has all the data. Column 1 is primary key and there is NO identity column.
This statement still throws Primary key violation error. Am clueless about this?
How can this happen when the target table is totally empty?
Chintu

Nope thats not true
Either you're not inserting to the right table or in the background some other trigger code is getting fired which is inserting into some table which causes a PK violation.

Session state protection violation

I turned on the session state protection on my application, the setting for Application Item, Page Data Entry Item and page display-only item are "checksum-required, application level". I want the URL to be shared by user in different sessions (for example bookmark). when I open two browsers (IE, Firefox) and login as same user, I copied/pasted url from one browser to another and received "Session state protection violation: This may be caused by manual alteration of a URL containing a checksum or by using a link with an incorrect or missing checksum."
Did I misunderstand the intent usage of this feature? I also noticed that checksum generated by the system remains the same no matter what checksum level I set (application, user, session).
I am running APEX 3.1.0.00.32.

Cheng-Lu,
I didn't forget you, this was a very difficult problem to debug.
I think I have a workaround for you. I added a page process to your login page named "fix deep link item". This restores the value of FSP_AFTER_LOGIN_URL that gets passed to this login page and is supposed to be immediately saved in session state. Due to a bug, this value was getting truncated to "f" before it could be saved. The new page process looks at the current URL and uses the value there which is still intact and saves that value in session state. I tested it with your applications. Please let me know if this works. We'll make a proper fix in the 3.2 release.
So this was not a problem with session state protection but in the "f" procedure which parses argument names/argument values in f?p URLs. This gets tripped up when an argument value contains a pattern like &cs= which is first treated as an argument to the orignal "f" call and therefore is never seen as an argument value in the list of arguments.
I have some other observations about your applications. I see that they have code in the page sentry function attribute of the authentication scheme. The code you have in there is completely unnecessary and could actually make the application less secure. You should leave this attribute empty and let the default (built-in) page sentry do all the work.

Protocol Violation Error (ORA-17401)

Hi everyone,
I was problem while run cfm page, for 4 weeks ago, the ColdFusion stop in error Protocol Violation Error - ORA-17401.
I'm using JDBC Oracle connector version 1.6 with Oracle 11 g.
Where the error show, the server stop communication from Oracle and returns only restart the CF Service, other servers dont stop communication.
I have 4 servers with 4 processors Quad-Core, 32 GB RAM and 1 TB HD, with Windows 2008 and IIS 7.5.
The ColdFusion is update level 11.
Any answers?

It is seen when Oracle.getSystemProperties fail to bring in Data from Oracle Server. At that time every property is returned as null, so protocol violation occurs. It occurs and Oracle Can't close Connection as said by the first thread.
Solution is to avoid too many requests at same time but use some long queue mechanism and timings.
