Data for the problem of dynamic regions was interrupted

Hello. I use JDev 11.2.2 and stack complete ADF.



This is when I try to load a new stream of work of a dynamic region. Let me give a step by step test case:



1 - using HR, model of generation: create objects (entities, objects View) for the employees and departments tables and an Application Module.

2. - in VC, add a page facelets with layout of two columns, first for a tree for the switching of regions and a dynamic region in the second column.

3 - create a page fragment that includes a generated table view in data controls and another fragment of page view of departments.

4 - create two workflow bounded, for fragment employees and another for the fragment of departments.

5 - drag and drop workflow bounded to create a dynamic region in the second column of the home page. Of course by selecting backingBean for new bean (default value is increased demand).

6 - in the model, create a static filled List View object with two attributes: a workflow id and a description

7 - in VC, generate a tree in the first column of the home page

8. - write a component of the tree selection listener to read the id of the current workflow and set this ID value of workflow dynamic region at the appropriate bean.

9 - set triggers of partials in a dynamic region in the homepage to listen for events from the tree.



10 - run and try to load a new workflow clicking in the tree. An alert is triggered with this message:


* "The content of this page could not load as expected because data transmission has been interrupted. Please try again or contact your system administrator. » *



And the newspaper is displayed as a result of lines:


* < FaceletViewHandlingStrategy > < handleRenderException > error rendered View [index.jsf] *.

If the taskflow taskflow id that has not worked is established in bean area Dynamics initial taskflow for the region, it works, but the other taskflow fails...



Any suggestions?

Hello

+ "Make sure selection backingBean to new bean (default value is increased demand)". "+"

That's your problem. Set the viewScope bean to avoid dynamic region to switch back to the default workflow after each request

  • Please HELP * problem with dynamic regions ADF...

    Hello

    I have 2 separate workflow in my application. 'Search-user-flow' & 'create-user-flow. I got to view these feeds in my main application (home) as a dynamic region with 2 dynamic links.

    My page main split into two panels where I suppose to display dynamic links on the left side and the workflow right. Want to display the default search feeds loading the home page, and when I click on the link for the user to create, create flow must be exposed to the right side. Please help me how to do the same. I was halfway through the path, but not totally.

    Here's what I've done so far.

    Step 1) creation research-user-flow (this stream were only page fragments not pages)
    Step 2) created create-user-flow (this stream were only page fragments not pages)
    Step 3) slide / move the search-user-flow in right panel of the main page as dynamic and created new "searchFlow" managed bean and the same card.
    -(After this stage, the main research stream fragment appears in my main page)
    -(Managed bean created taskID entry and the method)

    Step 4) slide / move the create-user-flow to the left side panel as dynamic link.
    Step 5) slide / move in the research-user-flow for left side panel as dynamic link.

    During the loading of my main page, I could see 2 dynamic links in the Panel left side and 1 flow to the right side panel. Now when I click on the Create User link, it's pass the stream and display the stream of the 2nd on the right. So far so good. Now, if I hit any link here after an error. Please help me how to solve this problem and make the works of dynamic region. It is really urgent and fight with past 4 days...

    Thank you

  • Write delay failed unable to save all the data for the file $Mft

    Have a frustrating problem.  Help is greatly appreciated.  Learned the hard way and lost a dwg important issue which was unrecoverable.  Bought a new drive external hard seagate.  Could not back up the entire system with software pre-installed.  Download acronis true image home 2011.  Tried to backup system.  Receive error when trying to backup messages; 'Delay to failure of Scripture; Reading of the sector; Windows was unable to save all the data for the file $Mft. The data has been lost.  Have tried many fixes.  Unable to disable write caching method (grayed out / unclickable).  Played regedit 'EnableOplocks' is not listed to select.  Attempted to run microsoft 'fix it' and got the blue screen of death.  Short hair out of my head.  Suggestions appreciated.

    I don't know where Microsoft 'Technical support engineers' get their information.

    Write caching without a doubt "does apply to external hard drives", but it is usually disabled to prevent to sort the problem you are experiencing.

    I've seen several positions reporting to the same question that you do.  All of these positions were with SATA drives.  Is your Seagate eSATA drive?

    The disc is recognized as an external drive in Device Manager?  In Device Manager, go to the drive properties dialog box and click the policies tab.  An external drive should have two options: "Optimize for quick removal" and "Optimize for performance".  An internal hard drive shows the options as gray (with 'performance' selected), but there should also be a checkbox "Enable disk write cache" under the second option.

    What shows in your policies tab?

    If I understand correctly, "writeback" or "write behind" is implemented by disc material or its pilot.  If the option is not available on the drive properties > policies tab, I would suggest to contact Seagate support.

  • Anyone know a fix for the problem of gel (Xoom)

    Hey everybody. Does anyone know a fix for the problem of gel in the Xoom? Once from time to time, it hangs for a few minutes, and then "goes back to work. It gets really annoying.

    Hey everybody. Does anyone know a fix for the problem of gel in the Xoom? Once from time to time, it hangs for a few minutes, and then "goes back to work. It gets really annoying.


    Greeting debuisson,

    Welcome to the Support Forums!

    Are you using the browser (Google) stock on a very regular or frequent basis? If Yes, brief gel is a known problem due to a memory leak in the stock browser that Google has not yet difficult (there are under all versions of Android OS to date). Basically, the continuous browser to consume your memory over time, based on the sites you visit and the length of time, it is active, which makes the system pause/freeze periodically. There are two ways to deal with this, either install a third-party browser (such as FireFox, Dolphin, Opera, Chrome, etc.) or if you really prefer the stock browser, restart your Xoom every two days (to clear/free memory and cache).

    Apart from the browser, a third party application of thugs can cause this as well (especially if there are conflicts). The rule of this point, try to use a surveillance (as SystemPanel) application to monitor what is active in memory when you encounter the gel. Close active applications one by one until your gel goes and then locate the updated versions.

    Please let me know what you find.

    The work is probably assigned a group of windows, probably MAINTENANCE_WINDOW_GROUP. The task will run in this window. Try these queries.

    select schedule_name
    from dba_scheduler_jobs
    where job_name = 'AUTO_SPACE_ADVISOR_JOB';
    
    select next_start_date
    from dba_scheduler_window_groups
    where window_group_name = 'MAINTENANCE_WINDOW_GROUP';  -- or the value returned by the first query if different
    

    Since it is a work of Oracle supplied, I recommend you contact Oracle support. The trace file contains other useful information?
