Is the #{bidings} object accessible during  the ADF prepareRender phase ?

Hi everyone.
I am using JDeveloper 10.1.3.3 and my application uses ADF/BC-JSf.
I want to create a page with a button whose "disabled" property will depend on the value of a view object attribute of the same page.
So what I did is I used a backing bean with a managed property named bindings with value #{bindings} which in turn extends oracle.adf.controller.v2.lifecycle.PageController.
Then I overrode the perpareRender() function and tried to access the bindings object, which turns out to be null.
Can anybody please help me figure out how to set this up correctly ?
Thanks in advance
Thanassis

Thanassis,
What you might do is to add a transient Boolean-valued attribute to your view object; create a getter for it (public Boolean isXXX()). Then, just add the attribute to your binding (page def) and use disabled=#{bindings.XXX} in the page.
I don't think you need to be using a custom lifecycle.
Hope this is enough information to steer you in the right direction.

  • I am missing the add objects section from the fly out menu in Photoshop CS6. 3d workspace

    I am missing the "add objects" section from the fly out menu in Photoshop CS6. I am in the 3D workspace of Photoshop. "Scene" is highlighted and I have clicked on the little fly out menu in the upper right hand corner of that panel. The whole section that should contain, Add objects, delete objects, duplicate objects, all the way through reverse order is missing. The add lights section above and render section below it is there. I am not new to Photoshop, but I am new to the 3D section of Photoshops work space.
    I do know about creating a new layer in the layers tab and merging the objects together trick. But I kind of would like for the program to work correctly as I am sure that doing it that way will cause some sort of problems later in the work process.
    Below are the specs of my system.

    I am actually running windows 8. So I am not sure why it is saying windows NT. Anyway...
    Photoshop says that my software is up to date. I use Photoshop daily and everything else works just fine. I have looked through this forum and there is someone else who had the same issue as me but their question was not given a solution. So that is why I choose to post it again.
    Any help will be great. Thank you!
    Mark.

    I've made tests with four different 3rd party tools: OpenGL Extension Viewer, GPU Caps Viewer, Compute4Cash OpenCL Diagnostic Tool and Mudlord's Glide3x wrapper tester. All those tools report no problems with my video card driver and OpenGL/CL.
    I have contacted nVidia and based on reports from the tools and visual tests from GPU Caps Viewer nVidia support doesn't see a problem with my driver.
    I found sniffer_gpu.exe which according to Adobe Help pages is a kind of diagnostic tool and determines whether Photoshop uses the graphic card OpenCL or not. Here is the output:
    Device: 00000000002B1BE8 has video RAM(MB): 1023
    Vendor string:    NVIDIA Corporation
    Renderer string:  GeForce GTX 650/PCIe/SSE2
    Version string:   3.0.0
    OpenGL version as determined by Extensionator...
    OpenGL Version 3.0
    Has NPOT support: TRUE
    Has Framebuffer Object Extension support: TRUE
    OpenGL ok
    OpenCL ok, version=1.1 CUDA 4.2.1
    Return code: 3
    From Adobe GPU Sniffer tool, it looks OK.
    On the other hand, I have your word that there is no problem with Photoshop not recognizing OpenCL for my card and that nVidia driver has problems. Can you justify this somehow? Perhaps you could provide more details on technical level, or another utility to run and extract details, to at least identify the problem Photoshop has and hopefully solve it on either side.
    P.S. During tests there were two things which I noticed, but they are probably not related to the issue:
    1. One tool reports the lack of Windows registry key SOFTWARE/Microsoft/Windows (NT)/CurrentVersion/OpenGLDrivers. But according to your previous statement, Photoshop only uses OS calls, no registry and according to nVidia, this key is not used in Windows 7.
    2. During some tests GPU Caps Viewer reports that "OpenCL CPU not supported on the selected platform". This is not complaining about GPU, only about CPU. But Photoshop is complaining about GPU, so it shouldn't be relevant.

    I have continuously over the last 6 months struggled with syncing my iphone and ipod with itunes  The app continually crashes during the picture import.  AND by the way it takes 10-15 minutes before it even attempts to import photos.  The screen says importing photoes but doesnt try to optimize or anything for 10 minutes.  I have a 3gs with 16Gb so its not a cheap phone.  I have 10Gb free.  I have 6600 photoes.  This is very frustrating and undermines my confidence in your products.  My ipod is an ipod 4 with 16Gb also.  It does the exact same thing to it.  The last time, I had to import photoes a few at the time and with it taking 10-15 minutes each time for 6600 photos it is a long frustrating process.  But it will import every photo a few at a time.  The error message is just that itunes has stopped working.  no hint as to why. AND of course, my phone is out of use for the entire time.  You guys must not want to believe ur phones are a necessary tool...or maybe you dont want the consumer to believe it is.  I have tried to find solutions on your website as well as through other 3rd party communities.  Ultimately they were of no use.  I stumbled onto my solution by accident since Im a bit of a computer geek...a semi-geek.

    I have this issue too, I went into my Windows event viewer. (should have looked at this a year ago when this started)
    it said this

    basically whenever I try to sync my ipod touch 4G 64GB it crashes iTunes when it begins the pictures. if im lucky ill get 4-5 on there before it stops responding. its not my system or anything im running win7x64 8GB DDR3 ram (Corsair XMS3) AMD FX Eight core processor.
    It is silly that iTunes cannot add pictures to apple devices. it shatters whatever incline I may have to buy apple products. knda like the Airport Extreem router my dad bought the new firmware, caused my router to not function... why release firmware that breaks a product. -_- <-- off topic but still

    With Lion and later there is no such thing as a server version of the operating system, this is unlike the previous Mac OS X 10.6 aka. Snow Leopard which did have a specific server version of the operating system.
    So, in reality one only needs Lion, Mountain Lion and Mavericks versions. The server software is merely an application these days.

    Hello Fellow iBook Authors!
    Today I received the same error that you all have been discussing.  I tried selecting the DRM
    and this did not work for me, though I'm glad it did for some.  Here's what I did as a work-around. . .
    Since iBooks Author did not have a problem with Videos, I simply used one of my video programs, ScreenFlow to turn the audio into a video file m4v.  I added an image and extended the length or timing of the image to span the length of the audio file.  Then exported as an .mov.  I then opened QuickTime and opened the file and exported the file to iTunes. 
    You can use iMovie, Camtasia or any other progam that will allow you to export the audio as a movie file.  Does this make sense?  I hope this helps, at least in the short-term.

  • Fill the LOV with data during the execution

    Hi
    I am using Oracle 10g
    I want to ask please if there is a way to fill the LOV with data during the execution
    so can I change the query specified in LOV wizard during the execution and get a new record set according to the value in the text boxes
    thank you for help

    You can use the SET_LOV_PROPERTY built-in to change the record group of the LOV and to create a new record group you can use the CREATE_GROUP_FROM_QUERY built-in.
    it will be something like this.
    RG_ID := FIND_GROUP('<record group name>');
      IF NOT ID_NULL(RG_ID) THEN
           DELETE_GROUP(RG_ID);
      END IF ;
      RG_ID := CREATE_GROUP_FROM_QUERY('<record group name>', '<your SQL statement here>');
      POP_GROUP := POPULATE_GROUP('<record group name>');
      SET_LOV_PROPERTY('<LOV name>', GROUP_NAME, '<record group name>');Use the online help for more information about these built-ins.

  • "there were not enough threads in the threadpool object to complete the operation" exception

    Post Author: crystalmatrix
    CA Forum: .NET
    I have a WinForm application using a Crystal Report Viewer control that in turn connects to a CR web service to display report. The client side application runs on WinXP SP1 with .Net framework 1.1, and the server is Win2k with ASP.Net 1.1. I am using CR XI out of the box.
    Users would periodically get "there were not enough threads in the threadpool object to complete the operation." exception when trying to launch the report viewer connected to the web service. The web service is a standard example implementation derived from CrystalDecisions.Web.Services.ReportServiceBase class. The problem usually happens when the user tries to open multiple report viewer forms, but once they get the error, it would continue to happen even after the user shuts down all viewer forms and then tries to launch a new one.
    There are some posts on the web regarding multiple asynchronous HttpWebRequest draining threadpool when running simultaneously and each one taking a long time to complete. However, our reports all run pretty quickly and results are usually returned before the next report starts to run. So my question is: does Crystal Report Viewer control has a problem with web service in that it may hold the HttpWebRequest thread even after the report is returned, or any other problem that may prevents the asynchronous thread being released back to the Threadpool? Anyone has experienced similar problems and has a workaround?
    Any advice is appreciated.

    Below is the exact requirement .... but there is no event generate right now  ... I feel that there are some configurations need to be done ..for the event to be generated ...
    It will be great if you have any idea about the configurations .. .
    Objective:
    When loan contract fees and repayment are posted from Treasury to GL, workflow should be activated to:
    a. Insert a payment block 'Z' in the document (Will need to create a user-table to define the criteria where payment block is to be inserted), AND
    b. Route the document for approval.

    If amount > 10,000, 2 levels approval required.

    You should not install it again..
    Boot the computer into safe mode and try the uninstall again.
    No luck you will have to manually uninstall which is a pain. Delete the files and open regedit and delete the registry entries.. better still use the system restore to go back to a previous system where you had no 4.2 installed..
    Or just ignore it and install the latest 5.6.1 and if it gives trouble well do a clean install of windows.
