Access error in the workflow area TabContext

I'm working on an ADF application that acts essentially as an IDE.  There is a page main jspx with a tree in a left navigation pane, then publishers (fragments) are displayed in tabs in the central content pane.

One of my pages is a dashboard and it contains several areas of Panel who have things like "Recently opened", "Recently published", etc.  Each box is it is a clean area with it's own Fragment.  They usually contain a list of the command.  I use the feature "Recently opened" illustrate the problem I have.

When I opened a new editor, I add it to a list in the grain of support.  The fragment in the region recently opened uses a tag af:forEach to iterate over this list and show the links of the command.  When you click on it, the link to order access this tab (if it is open), or open a new tab with this editor (be it was closed because it was added to the list).  The problem is when I try to access the TabContext, I see two scenarios.

In scenario 1, show the links of the command, but I get a Null pointer by accessing the context tab.  After seeing this in the past, in scenario 2 I added a parameter to the workflow for tabContext and got a new error.

Error of scenario 2: < MISSING_REQUIRED_PARAMETER > < /WEB-INF/flows/recentlyOpenedFlow.xml#recentlyOpenedFlow > tabContext

Hi Scott,.

Looks like you're missing to set the task input stream parameter tabContext to the recentlyOpenedFlow on the page of main_dashboard binding.

When you open the main_dashboard page, click the links tab, click the recentlyOpenedFlow in the executables section, you will see the input parameters are listed.

You can set the value with the tabContext of calling traffic there. However I'm no expert on the boss of Shell of the user interface, so I don't know if the tabContext is serializable parameters need to be as far as I know.

Otherwise, the record output will let you know...

  • Do "request failed: ' error after the workflow run 'assign a state change.

    I try to start a workflow that sends an email once a machine is put into operation.  A simple task, I think.

    I have installation vRA and vRO and am able to supply machines form vRA before making further changes.

    In vRO, I ran the workflow of customization of the vCO 'Install', and the workflow "to assign a workflow of change of State of a master plan and its virtual machines.  After you run the last workflow, I get the error "'request failed: not found YUNoWork and perhaps even deleted before commissioning end." when you try to configure a machine to. "

    The workflow of messaging works on its own, and after the execution of the workflow «Assign a state change...» ", I see not updated the property of 'WFStubBuildingMachine' on the action plan.

    Any comments would be greatly appreciated!

    The issue was that endpoint vRO was not added to the vRA.  After you add endpoint and the taking of the inventory, the problem has been resolved.

    We recently patched to 11.1.2.1.600 for our planning solution and we get an error msg in the workflow.

    If the "hierarchy of planning unit" is configured as 'Free form', we get an error message if users open "Manage trusts", select "Details" of a planning unit and then '' change of status. '' The message error is "is there no valid action that can be performed on the selected planning units. If the "hierarchy of planning unit' is defined as 'Bottom up', it works fine.

  • Troubleshooting installation printer driver on the computer. error message: "the arguments are invalid.

    I recently purchased a Brother (MFC-J265W) all-in-one printer that has a wireless capability.  I finished configuring wireless from the machine, however when I tried to install the printer drivers by using the CD-ROM, the installation failed because an error message indicates that "arguments are invalid".  I contacted brother customer service and they said it's a matter of Microsoft.

    A few details:

    I use Microsoft XP Home edition 32 bit SP2. It came installed on my laptop (Acer).

    I've uninstalled and reinstalled the driver several times, but I get the error message.

    I tried to download and install the latest driver from the Brother Web site, but I still get the error message.

    Specifications (in the manual and on the Windows website), the printer IS compatible with Windows XP.

    I would like to know how to solve this problem and also to understand what means the error message.

    Thank you

    When a hardware vendor says "It's a problem of Microsoft", without providing further details, you can be sure that you talk with a person of lazy tech support who wants to end the call and does not know how to solve your problem.

    I suggest that you completely uninstall some pieces of the printer driver and the associated software are already installed using the directions here: Article 1.  Then, disconnect your computer from the Internet, run your antivirus application disable (disable realtime protection) and install the printer as if you planned it or connected to the computer via the USB port, but do not connect the USB cable until you are prompted to do so.

    If you successfully installed printer as a USB printer, converting the wireless connection should be reasonably simple :-).

    If the above procedure doesn't help, especially if you get the same error, return brother support and request that escalating the issue until you find someone who can help you.

  • Can not open Illustrator CC 2015, read/write permissions error, but the permissions are set correctly.

    I can not open Illustrator because of this error.

    "To work properly, Adobe Illustrator requires permissions of folder preferences be"read-write..." »

    Link support on the error message suggests to change permissions to a file location that does not exist. All permissions are set to read-write, and no changes have been made since the upgrade to 2015.  Uninstalling and reinstalling did not work.  Very frustrating to pay for a product that I can't use.

    I solved the problem by resetting the permissions of my entire disk (apply to items included...). I still can't explain why it was necessary after the upgrade to 2015 from 2014 CC CC.

  • Windows Explorer error 0x8007007A: "the data area passed to a system call is too small" and will not accept simple word doc to a new file

    I have seen questions about this error in Re (with no response) Task Manager, but it popped up just for me just trying to move a document to a new file (file) in Windows Explorer.  I'm not a techie.  I use a new Windows 7 laptop, networked with a desktop computer running XP - live files on the XP, so I guess it's an XP issue.  The file tree is quite long. I tried to delete and recreate the folder.  No luck.   New - I got a few word documents in a folder, I created a folder under the original, tried to move word documents & PDF files in the folder and suddenly get this error.  I created thousands of new records - never saw this before.

    The previous times I've seen that error (regarding printer installation issues or Scheduler tasks), if seemed to be linked to a care/firewall Windows. Just to smile, have you tried to disable any software firewall/security (temporarily) and see if that makes a difference.

    BTW, it's a new show (as a few update/install can be causing it) or always happened?

I changed the NETBIOS name of the virtual from Windows machine to comply with the new standards of the convention of naming on our network, and now I have the following problem when you try to access the page of material status on my hosts. It works fine if I connect directly to the host, but no longer works via vCenter... Someone knows how to fix this? It must have something to do with the change of name, because it worked fine before the change.

    You can check the /etc/vco/app-server/security/ddns-update.key file ownership/permissions?

    You can do this for example. running the following command in a terminal Linux

    ll /etc/vco/app-server/security/

    If the owner/group is set to root (maybe put the root when you copied the file), then could you change owner/group to vco with the following command, and then try to run the workflow?

    chown vco:vco /etc/vco/app-server/security/ddns-update.key
