Unable to Serialize ReportClientDocument using "StateServer" session mode
Hello,
In my ASP.NET application, I am using "StateServer" session state mode for maintaining session variables. The problem however is that this mode requires all the objects inside the session variables to be serialized and for some reason ReportClientDocument doesn't seem to be serializable.
Here is the code that's not working:
ceSession = Session.Item("ceSession")
ceEnterpriseService = ceSession.GetService("", "InfoStore")
ceInfoStore = New InfoStore(ceEnterpriseService)
rptAppFactory = ceInfoStore.EnterpriseSession.Interface.Service("", "RASReportFactory")
rptClientDoc = rptAppFactory.OpenDocument(rptId, CdReportClientDocumentOpenOptionsEnum.cdReportClientDocumentOpenAsReadOnly)
Session.Add(rptClientDoc)
At the end of the request it throws an exception
"Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode."
[SerializationException: Type 'CrystalDecisions.ReportAppServer.ClientDoc.ReportClientDocumentClass' in Assembly 'CrystalDecisions.ReportAppServer.ClientDoc, Version=12.0.1100.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' is not marked as serializable.]
Is anybody having any idea on how to successfully store ReportClientDocument in the session variable by using "StateServer" session state mode?
Thanks
There is a sample that demonstrates serializing the ReportClientDocument [here|https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/d0a4791b-9d3b-2c10-94a5-86088b6224d4]

Unable to serialize XMLElement using SOAP?
I'm using oracle AS 10.1.3.0 release. I'm trying to set up a webservice that will accept an Element (which I've done in prior releases no problem). When I attempt to call the webservice I get the following error:
Caused by: java.lang.IllegalStateException: ComplianceImpl.printTags: Failed result = [SOAPException: faultCode=SOAP-ENV:Client; msg=No Serializer found to serialize a 'oracle.xml.parser.v2.XMLElement' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.; targetException=java.lang.IllegalArgumentException: No Serializer found to serialize a 'oracle.xml.parser.v2.XMLElement' using encoding style 'http://schemas.xmlsoap.org/soap/encoding/'.]
Now I'm unsure what I'm doing wrong unless Element support has been deprecated as we move towards JaxRPC. Here is my interface call and wsdl:
public Element printTags(Element elem) throws Exception;

A rundown of what I've tried:
Adjusting energy settings to try to prevent sleep
Pluging the USB keyboard and wacom tablet directly into the laptop (as opposed to a usb hub)
My laptop's power cable is connected
My display (a Vizio TV) is recognized in the System Preferences panel
I'd been using this TV for about a year with my older Macbook Pro (OS 10.5.8), though using a different wireless keyboard and mouse
***Update: The issue seems to lie with the keyboard and wacom tablet. I am trying to use a wireless Case Logic keyboard (with dongal) and wired wacom tablet to wake the Macbook Pro in clamshell mode. To experiment, I tried using my Logitech wireless keyboard & mouse set (also dongal) that I had been using before and it wakes the computer without any problems! However, I really need to be able to use my wacom tablet. If I switch to the tablet after waking the computer using the Logitech keyboard & mouse it works, but once the computer sleeps it won't work anymore. I could keep switching back and forth I suppose, but it's sort of a pain. There has to be an easier way! Any ideas why the wired wacom tablet is unable to wake the computer in clamshell mode?
Thanks!So your keyboard or mouse won't wake the Mac when you close the lid correct? Try resetting the SMC and pram
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys. -
Using Delayed Locking Mode along with Serializable Isolation Mode - problem
hi all,
I have a form that includes 2 blocks (master-detail) and I've set locking mode to delayed cause I don't want records to be locked while user is changing them but only when a COMMIT is issued.. Along with that I set Isolation Mode to Serializable as online help dictates.
Problem is that since I've done this, record seems to be saved correctly but it actually does not when i issue a COMMIT (tried it with commit_form and do_key('commit_form') and with post and then commit). I get no error message and transaction seems to be completed but nothing happens on the db.
What I've noticed is that when I issue a COMMIT with delayed locking mode on, the ON-LOCK trigger does not fire at all while it should (cause that's what delayed locking mode is supposed to do lock the record only while commiting). Does it have anything to do with my problem?
please send any ideas you might have on this
thanks in advance,
teoWhy you use Isolation Mode = Serializable?
Forms help says:
"Use delayed locking if the form's Isolation Mode property has the value Serializable."
not
"Set Isolation Mode to Serializable if Locking Mode property has the value Delayed".

Unable to filter a recordset using a session variable
I have a volunteer application page and when the volunteer presses <Submit> their info is saved in a MySQl db table and a session variable is created containing the primary key of their record in the table, control is then passed to a "success page". The success page can access the session variable (I proved this by displaying the session variable on the success page) so my next step was to create a recordset in the success page with a filter using the session variable to select the appropriate row in the table, allowing me to display to the volunteer the info they submitted.
I set up a test success page which displays the session variable and one field of the volunteer info. When I test this I see the session variable displayed but the corresponding volunteer info field from the recordset is not displayed.
The volunteer application page is here www.hollisterairshow.com/volunteerapp.php and the successpage is here www.hollisterairshow.com/thanksvol.php
The code that creates the session variable in the volunteer application page is shown below
$_SESSION['volunteer_id'] = mysql_insert_id();
The code to display the session variable in the success page is shown below
<?php echo $_SESSION['volunteer_id']; ?>
The code to display the volunteer info is shown below
<h1> Thank You <?php echo $row_rsVolunteerApp['firstname']; ?>!! </h1>
The recordset definition is shown below
The success page test result is shown below, as you can see the volunteer's first name is not displayed immediately after the "Thank you" message but the session variable holding the correct primary key (41) is shown correctly.
Does anyone have an idea of what I'm doing wrong?
Thanks
TonyWhere did you put session_start()? It needs to be before the variable is accessed. It's obviously before the line that displays the value in your page, but is it before the SQL query is generated?
Also, have you checked in phpMyAdmin to see whether volunteernumber 41 has any values in the database? -
i can't think of anything else to add. i've always been able to use full screen mode in firefox, it still works on vimeo and it still works on NEtflix..
What happens when you try to use full screen mode -- button is ineffective, video doesn't display, etc.?
By the way, Adobe has issued a couple of security updates recently, so you might want to update your Flash plugin. -
Unable to edit document using "Edit with Word" option
Hi All,
i am having an issue with Office web apps. i am using SharePoint 2013 and Office web apps 2013. all the configurations have been done successfully. but i have a different kind of issue.
i am able to open documents in browser
i am able to edit document using " edit with word/excel web" option
but i am unable to edit document using "edit with word/excel" option
i have Office 2010 installed on my local machine.
do we need to have MS office of 2013 version? or is there anything missing from configuration part.
Please help me.
Thank You,
Bhaskar.Hi,
According to your post, my understanding is that you could not use the "edit with word/excel" option.
I had tested the issue with the Office 2010, the option worked well.
You don’t need to install the Office 2013 to use this option.
What did you mean “but i am unable to edit document using "edit with word/excel" option
Did you mean the option gray out? Did the issue occur in other browsers?
You can use compatibility mode to check whether it works.
Open IE->Tools->Compatibility View Settings
You can also add the site into Trusted sites.
Open the IE->Internet Options->Security->Sites->add the site into the Websites, then check whether it works.
What's more, you can also use other browsers to check whether it works, such as Firefox, Chrome.
Thanks & Regards,
Jason

Note how the error is reported to be a column 74 on line 2, yet line 2 of the above block should only have 58 characters, so at a pure guess somehow there's extra whitespace on line 2, that is confusing the PL/SQL compiler, I suggest re-typing the PL/SQL handler manually and seeing if that cures the problem. -

We noticed your app declares support for location in the UIBackgroundModes key in your Info.plist but does not include features that require persistent location.
It would be appropriate to add features that require persistent use of real-time location updates while the app is in the background or remove the "location" setting from the UIBackgroundModes key. If your application does not require persistent, real-time location updates, we recommend using the significant-change location service or the region monitoring location service.
For more information on these options, please see the "Starting the Significant-Change Location Service" and "Monitoring Shape-Based Regions" sections in the Location Awareness Programming Guide.
If you choose to add features that use the Location Background Mode, please include the following battery use disclaimer in your Application Description:
"Continued use of GPS running in the background can dramatically decrease battery life."
Additionally, at your earliest opportunity, please review the following question/s and provide as detailed information as you can in response. The more information you can provide upfront, the sooner we can complete your review.
We are unable to access the app in use in "http://www.wayding.com/waydingweb/article/12/139". Please provide us a valid demo video to show your app in use.
For discrete code-level questions, you may wish to consult with Apple Developer Technical Support. When the DTS engineer follows up with you, please be ready to provide:
- complete details of your rejection issue(s)
- screenshots
- steps to reproduce the issue(s)
- symbolicated crash logs - if your issue results in a crash log
If you have difficulty reproducing a reported issue, please try testing the workflow as described in <https://developer.apple.com/library/ios/qa/qa1764/>Technical Q&A QA1764: How to reproduce a crash or bug that only App Review or users are seeing.Unfortunately, these forums here are all user to user; you might try the developer forums or get in touch with the team that you are working with.

Unable to open jsp file in Design mode
Hi,
I am unable to open jsp files in design mode, I am using eclipse Version: 3.6.1.
Please help.
Regards,
Ale HasanHi Ale,
Thank you for the additional information. Unfortunately, there does not seem to be anything unusual about your project based on your description. I'm surprised you don't see any processes listed in the process view while waiting for the page to open. I thought you might see something related to a queue manager job to "Manage Resource Event Jobs".
Are there any messages in the error.log? You can open a view to the error log from the menu option, "Window -> Show View -> Error Log". I'm curious if there are any messages about a process timing out, unable to reset some object within a certain time, or any exceptions logged.
If you change to another workspace with just a single JSF web project containing a smaller number of JSP, do you experience the same behavior?
Can you also try using a more recent release of OEPE to see if that helps? The 11.1.1.6.1 release is about a year old.

Kind regards,

Xcelsius 2008 - Unable to preview changes made in design mode
Xcelsius 2008 - Unable to preview changes made in design mode
I have installed Xcelsius 2008 (RTM) and also Service Pack 1 / Fix Pack 1.1. Unfortunately, I can now not preview changes I made in design mode (but can see the change in design mode). In addition, if I save the changes made to the Excel spreadsheet (using this as the datasource) and then exit out of the application, then go back in, the changes have not been saved?!
I have also installed Fix Pack 1.3, but the same issues occurs.
This is causing us issues as we have developed a number of dashboards that can no longer be updated.
Please could someone advise?
Many thanks,
Neil.I would recommend decomposing large sets into more manageable sets. For instance, if you have data for a very large regional district, decompose the data into smaller sets for sub-districts.
As for a paper, I'm not sure, but the main determinant of performance is how many cells you bind to the component. For a typical component on a typical computer, I'd recommend no more than 9000 cells. On a weaker computer less, on a stronger computer more. -

Can we create multiple session in BDC using Call session?
Hi Experts,
Can we create multiple sessions in BDC using Call Session?
Scenario:
Program has to upload 1 million records,so can we programmatically create multiple sessions such that after every 50thousand records we create a different session.
For moment due to large number of records BDC DYNPRO and BDC Field are unable to hold the large number of records,due to which we get a Out of memory error.
Thanks in advance.
ShilpaHi
If ITAB is your table with the data to be transfered:
Open the first session:
CALL FUNCTION 'BDC_OPEN_GROUP'.........
IF SY-SUBRC = 0.
FL_OPEN = 'X'.
ENDIF.
LOOP AT ITAB.
IF FL_OPEN = SPACE.
Create new session
CALL FUNCTION 'BDC_OPEN_GROUP'.........
IF SY-SUBRC = 0.
FL_OPEN = 'X'.
ENDIF.
ENDIF.
Here elaborate your data and fill BDCDATA
Insert the transaction:
CALL FUNCTION 'BDC_INSERT'
IF SY-SUBRC = 0.
COUNT = COUNT + 1.
IF COUNT = COUNT_MAX.
COUNT = 0.
Close the session
IF FL_OPEN = 'X'.
CALL BDC_CLOSE_GROUP
IF SY-SUBRC = 0.
FL_OPEN = SPACE.
ENDIF.
ENDIF.
ENDIF.
ENDLOOP.

Unable to set safari in full-screen mode
Hi folks,
I just factory reset my 15-inch MBP running 10.9.3. After doing so, I notice that I am unable to set Safari in full-screen mode. Any ideas??Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.
