Portal does not retain HTTP request parameters

We are trying to do some basic pagination functionality using JSP tags. The problem that we are having is the JSP tag places request parameters in the URL that it creates. The tag then expects that these parameters will be available in the request when the page is rendered after the link is clicked. This JSP tag works great with normal pageflows but with the Portals concept of nested pageflows this no longer works.
The problem is that these request parameters are not available in the request but only in the scoped request. How can the JSP tag in the JSP page get these parameters out of the request object?
I can see the parameters in the ScopedRequest but not in the normal request. This is a major issue since the JSP tag has no knowledge (nor should it have to) of the concept of a Scoped request. The pageflow can access the parameters in the scoped request but there is no way to set parameters in a request.
Is there a patch that places the parameters in the real request? Is there a work around for this?
Thanks,
Chris

A couple options -
1. Try using the OuterRequest
2. You can prefix the portletinstance to the request parameters to get them from the main request object
3. Try using the BEA grid for pagination OOTB.
Hope this helps :)

this returns an error code 11: The signature of the request does not match the request parameters.

Any hint will be greatly appreciated.
UPDATE: I already checked the HMAC encoding using a third party service and it returned the same as my app

I figured this out (God bless Pair Programming):
I was signing incorrectly:
On the newApplicationCreationInfo:
My Shared Secret is : gBksYDAqcuAUXK+zyvfFW9F0sy8nchwnplJ6K7aKmAM=
But BEFORE hashing the "<content>...</content>" i need to decode my secret that is:
hmacsig = calculateHMAC256(content, sharedSecret.decodeBase64())

Error: Path to object does not exist at Request

Hi experts,
i have a scenario asynchronous/syncrhonous: file to rfc and get back response rfc to other file. I have 3 communication channel: 1 sender file, 1 receiver file, 1 receiver RFC. The communication channel sender file show the follow error:
Attempt to process file failed with com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Path to object does not exist at Request, the whole lookup name is localejbs/AF_Modules/Request/ResponseBean.
I do not understand how modules(AF_Modules/Request/ResponseBean) in adapter works, the documents that I have found I am not much has clarified, could someone please explain and tell me something's error?
very thanks,

Hi,
Check the receiver agreement, you might have configured the file receiver communication channel name instead of the RFC receiver communication channel name.
Also check the module parameters in the sender file CC

Common Services portal does not appear on the LMS 3.0 homepage

Hi,
I am encountering a problem on Ciscoworks LMS 3.0 wherein the Common Services portal does not appear on the homepage. This was after I tried to upgrade CW to LMS 3.2 but does not seem to work so I revert back to LMS 3.0. I even did a restore of the backup database but still no Common Services on the homepage.
How do i resolve this?
Appreaciate your help. Thanks in advance!

If you're not seeing the Common Services application portlet on the Functional Portal View, then you need to open a TAC service request to get the steps to manually re-register all of the installed applications from the command line.

Scroll bar does not retain its position after or before pack

Hi
My Scroll bar does not retain its position after pack in my application.
But i need to retain its state.
My code snippet is :
System.out.println("VAlue--->" + getHXValue());
scrollPane.getHorizontalScrollBar().setValue(getHXValue());
pack();
My VAlue printed is 100.
But my positon of scroll bar is at 0 th location.
Can any one help me.....

Swing related questions should be posted in the Swing forum.
My code snippet is :Snippets don't help.
If you need further help then you need to create a "Short, Self Contained, Compilable and Executable, Example Program (SSCCE)",
see http://homepage1.nifty.com/algafield/sscce.html,
that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting.

Does not retain sort state

App Store does not retain sort state when returning from viewing an individual app to the full list of apps. If the full list spans more than one page, the page you were on is also not retained.
I have no idea if this is a bug, a feature (or lack thereof), or an oddity on my computer. Since I can't find any other way to request a feature or post feedback to Apple, I'm putting this here.
If by some chance this is an issue with my computer only or I'm missing some preference somewhere (ha!) I'd appreciate any help provided by the community.
-s

Yes, it is indeed VERY frustrating that the App Stores don't return you to where you left off browsing if you stop to click on an app to read more about it. Once you're done reading about an app that interests you, you're dumped right back at the beginning. So, just to get back where you were, you may have to plow through ten pages of apps. I get so fed up with being whisked back to page 1 all the time that I just give up and leave the App Store in disgust. I hate wasting my time paging backnthrough all the apps I've alread covered. ALSO, when looking over GENIUS recommendations on the App Store, why is it that even when I click on NOT INTERESTED for a given app, the app just stays there? It's like my clicking NOT INTERESTED has no effect whatsover. What's the problem with the App Store?

IMPORT Target Portal does not match the Source Portal version

Hi,
Executing the import via the command line gives me the following error: Error: Target Portal does not match the Source Portal version
Cannot proceed with Import
Checking the output of the script tells me that the portal source has version 9.0.2.6 and the target 9.0.4.0.
Does this mean that there is no backwards compatibilty?
How should I continue from here?
Best Regards

Portal Export/Import utilities are designed only to work between Portals which are at the same version level.
For more information, please see this section in the Portal Export/Import FAQ for 9.0.2.6:
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/OTN_CONTENT/MAINPAGE/DEPLOY_PERFORM/9023_EXPORT_IMPORT_FAQ_0308.HTM#question_5
OracleAS Portal allows you to upgrade your existing content to the latest release of Portal.
What you need to do in your particular case is to upgrade your existing portal installation from 9.0.2.6 to 9.0.4 before using Portal Export/Import between your two portal instances.

The server does not support the requested critical extension (0x8007202c)

Hello guys,
The sympton is the same as the one in "The
server does not support the requested critical extension." Exception.
I got the error in calling IDirectorySearch::GetNextRow. As I observe, the error is trigger when retrieving the another page of records. The LDAP path to connect is "GC://<FQDN_of_GC>". The search filter is (&(|(objectClass=group)(objectClass=msExchDynamicDistributionList))(mailnickname=*)).
There are about 100 thousands of group objects in the forest. So the answer in that thread does not help.
Any thoughts?
Thanks.

Hi Michael,
Thanks for your remind of the server is Windows 2008 R2.
After deep research on this topic, there were a couple of possible causes. One was based on asking AD to do sorting on the results of the query. Our calls to AD do not do any sorting at all. The other I came to was a couple of pages that may help alleviate
the problem of groups in large AD environments. It has to deal with the temporary table size that Active Directory uses, with the tunable parameter MaxTempTableSize.
The articles as below are for your reference:
http://social.technet.microsoft.com/Forums/en-US/exchangesvradmin/thread/95bfb95f-4e43-4dd8-ac3a-0c89d2cf528e
http://support.microsoft.com/kb/315071
http://msdn.microsoft.com/en-us/library/ms677927(VS.85).aspx
Besides, if the above is not the cause of our issue, there may be something wrong in the C# code. Since I just an AD engineer and not familiar with the C# code, I suggest you should involve one C# code engineer to work with us about this issue. After doing
many research, please add the class of the object when searching. For example, “DirectorySearcher ds = new DirectorySearcher(de, filter,class)”. I’m not sure if it’s correct, just a suggestion.
Hope to hear good news from you soon. Happy X'MAS day!

Firefox 29.0.1 Does Not Retain Options Settings. Cookies Enabled.

On only one of my XP profiles, Firefox 29.0.1 does not retain the settings made under tools-options. I have deleted the cookies from Mozilla on the chance they may have been corrupted and have also cleared the web cache. The problem remains. Also, it is not clear in the new version how to have Firefox ask you each time before a cookie is accepted. Thanks for you help.

You can try to delete the cookies.sqlite and permissions.sqlite files in the Firefox profile folder.
You can use this button to go to the currently used Firefox profile folder:

MW64, cs6 bridge when I move or copy files the context menu does not retain recent folder destinations after I close the program

W64, cs6 bridge when I move or copy files the context menu does not retain recent folder destinations after I close the program. The context options that show are the ones from original install. The workspace I set up is also gone. I have every explorer box and cleaner checked to save recent. Had to disable nivedia desktop software because of weird display conflict. Have Dell pro support and they cannot fix. Any ideas to help me with this would be appreciated.

Self-solved! I work in column view in Finder so get there in a Finder window with folders and files appearing.
There really is no problem, just select an ITEM in the COLUMN before right-clicking!
The "old" context menu will appear. If you click in the white space in that column (or anywhere in a Finder window) and then place the cursor over a folder or file WITHOUT selecting it and right-click you will bring up the secondary context menu - Open, Copy, Duplicate, View Options and a greyed out Labels option. No "Move to Trash".

Copy and Paste on Safari 5.0.2 does not retain formatting

Hi there.
I'm on Safari 5.0.2. and when I copy and paste something (in this case, on a message board--vBulletin, but it doesn't work on anything else) it does not retain the original formatting (for example--bold, italics, underline, etc.) If I copy something from Safari and paste it into another program, TextEdit for example, the formatting remains and works fine.
This is extremely annoying. Anyone have any ideas?
*If you're on Safari, try copying* and *pasting this sentence in a reply* --it will remove all the formatting for some reason. It will work in TextEdit, however. It's not just this message board software either...try it somewhere else too.

Hi
copying formatted text & pasting in Safari does retain the formatting, so long as the place you're pasting it supports varying fonts/styles.
So copy/paste here, just shows as plain text.
c/p to blogger.com in the 'compose' tab - works fine
c/p to blogger in the 'html' tab - plain text
same with textedit: paste from safari to textedit +in a plain text document+ -you get plain text.

Is there a save option on iPhoto? Sometimes iPhoto does not retain the name on a face I've added to a photo.

Sometimes iPhoto does not retain the name on a face I've added to a photo. I have 'added a face' then flipped to the next picture then back to that picture and the label has disappeared.

No. It's supposed to be automatic. You might try repairing the library's database and then see if it still crops up now and then. If that doesn't help try rebuilding it the same way.
Launch iPhoto with the Option+Command keys held down and select the database repair option in the rebild window:
Then the rebuild option if necessary.

APP-FND-01702 An assignment does not exit for these parameters

Hi,
I am facing this below error in AP,AR,CM,GL Modules. If any one knows the solution plz revert back ASAP,
I encountered the error message when I created an invoice in AP module:
APP-FND-01702:An assignment does not exist for these parameters and one is mandatory.
Cause:The profile option Sequential Numbering is defined to have
sequential numbering always used. The current set of parameters does not have a sequence assigned.
Acction: Go to the Assign Sequqnces screen and assign a sequenct to the current set of parameters.
Regards,
senthil

Hi Senthil,
this is an issue with the configuration only, when the profile option is Always used system is referring to your Sequential numbering configuration, which seems to be not right / incomplete...Hence verify whether you have defined assignment for all the categories in the modules and re-test the same again ....
You can change the profile option value to Partially used, which will not throw an error, it would only give you a warning ..
