    I ask just because adding, the designer of the CSS is great, but the three could help me work faster with the three components.

    The combo would be great, but I can't seem to get a view HTML, CSS and view Live or at the same time.  Is there a way to do it?

  • Fill the tree with complex external XML file control

    Hi all. I've been combing through forums for two days and have not been able to find a solution to my problem. I'm trying to populate a control of the tree with an external xml file, but the xml file is not a simple. It is complex, and I don't know how to get the tree to display these data. I have attached the code. Can someone take a look and let me know how I could get this to work? Thank you!

    What does not work?

    Complexity of the XML is not, in itself, an issue for the tree.

    Also, I recommend using straight XML, unless specifically, you need Collection features.

  • Synchronize the forms with self-referential VO on the Board of the tree. POJO-based model

    Hello. I need your help

    Sample ADF Code corner #32 show how to build a picture of the tree to a self referencing VO:
    [http://www.oracle.com/technetwork/developer-tools/adf/learnmore/index-101235.html#CodeCornerSamples]

    Paper corner Code ADF Oracle JDeveloper OTN harvest/09/2011 by Frank Nimphius show how to build a form of modification of the table data and synchronize it with the selected line in the table of the tree:
    [http://www.oracle.com/technetwork/developer-tools/adf/learnmore/sept2011-otn-harvest-508189.pdf]

    These examples are useful, but I have a problem, I don't have a model based on a database, my application datamodel is based in POJO objects, there is no appModules or ViewObjects so I do not know how to reference the tree table attribute target with the iterator form edit.

    Can someone help me?
    Perhaps (I don't know how) I do a VO and an AppModule that encapsulates the model POJO?

    Thank you very much

    Hello

    It should work the same. You create a tree of a POJO data control based on your POJO model. Expose another collection pointing to the same set of data and drag it onto the form. Use the setting in the configuration tree dialog box to set the current line in the tree as aware of the iterator of form.

  • How to restore the calculator application to drag it to the top of the screen to control

    Can how I restore the calculator to drag it to the top of the screen to control center? It seems to have been removed from the bottom row? Thank you

    Are - what you got to remove the calculator of your applications on the phone? You can find the calculator on the phone itself? If you find it, then try a reset. Hold down the home and sleep/wake together until you see the Apple logo and then release. The phone will restart. There are no settings to change what appears on the display. See if the reset solves your problem.

    EDIT: what exactly you see in the Control Center? If you see only controls the music, then drag to the right to see the rest of the access to the control center.

    Advanced power settings go to Toshiba power Saver saver > cooling method. There are minimum level. Change back to your power management for a second power plan, and the fan must be much quieter.

  • Lean how to run the stop code when the highest level VI ends

    Hi people.

    I am a newbie of LV with 30 years of experience in embedded SW engineering.  I searched for how to run the stop code when a VI of highest level ends.  I found many examples, but they are horribly complicated.  A little birdie told me that such a model of simple design should not be so compilicated.

    My application is an application of high tension control to disable all HV checkpoints when the SW ends.  My VI code is running in a while loop with a stop button that leads out of the loop.  I can easily accomplish my requirement by programming with a sequence of plate that runs after the end of the main loop.  The technique of flat sequence does not work when the user clicks the Cancel button in the toolbar of façade, more than that market when the user clicks the close button of the application (X button) when you run the exe application.

    Can someone tell me please a simple technique, the code example that can show me a lean and elegant way to accomplish my task?  It doesn't have to be an obvious solution (for example a stop induced watchdog seems simple enough).

    Thank you - John Speth

  • How to adopt the validation of level entity such as BC ADF using EJB/JPA?

    I explore how to implement validation to entity level using the EJB/JPA instead of ADF BC. (Note: I use JDeveloper + ADF 12 c)

    1. I cannot add validation attribute level in the ADF (Data Control) of EJB model layer. but it is not enough. I can just code partial UI validation here.

    2. I googled and find that someone is using jsr-303-bean-validation. What is a unique choice? How the entity-level validation code?

    Validation of the JPA EJB ADF application entity

    3. I want to implement certain business validation and processing business in the layer of business ADF service, as in the EJB method.

    I did a simple test to simulate an exception, but I found the exception has been handled incorrectly in the layer of binding of ADF and error dialog box prompt: DCA-29000: Unexpected exception caught: java.lang.reflect.InvocationTargetException, msg = null.

        public Departments persistDepartments(Departments departments) {
            if(true){
              throw new RuntimeException("persistDepartments");
            }
            em.persist(departments);
            return departments;
        }
    
    
    
    

    Any expert can help? will I have to rewrite the ADF Model layer error handling? How to code the validation in EJB? you will need to take local and manipulate it in class in the ADF error handling model layer? where can I find a demo?

    4. I want to introduce a layer of application service between EJB session façade and JPA entity for the re-use of the company.  but I found JDeveloper helps me to do anything. I do code manually, when I create EJB session façade, it always integrate directly with JPA entity inside.  I expect that my application service is class instead of the EJB POJO.  Session EJB façade summons enforcement and demand serviceshall call JPA entity services.  is this possible? any sugguestion?

    Thank you

    Qn1, the ADF Model layer Validation are supported at the level of the validation attribute. It is confirmed.

    Qn2, it seems that this is a better solution, but is not Explorer so far.

    Qn3 is resloved by creating a custom error handler to extract a validation thrown from EJB exception and at the same time, it cannot be avoided that the thrown exception of service business layer is still dumped at MTS-out.

    Qn4 is reslolved by employment Commission to inject POJO, EJB session faade and inject POJO EntityManager (use JTA transaction).

    Thanks to you all!

  • How to check the mic or line level BEFORE recording?

    I used to use CoolEdit Pro 2000, then the first CS1 hearing (which was the same program as far as I could tell).  With earlier versions, I could follow the input signals and display the levels without actually start recording.  YES, I know that you can't adjust the parameters of audio of the hearing, but he must see the hearing levels before you know how to adjust the material.  I can't find how to proceed with the hearing CC.  Of course, I can start recording, get a check levels, then stop and delete the record, but it's stupid. So what don't understand me?

    And forgive me if this is a stupid question, but if it has been asked and answered before I can't find where.

  • How to control where the Messages appear on a Page

    Hello.

    I use Apex 4.2.1 on mod_plsql and Oracle 11 g 3.  My application uses theme 21.

    I noticed a strange behavior.  All my messages page such as the success of process messages ('changes have been saved") and even validation error messages ("date field must have the value") will all be displayed at the bottom of my page.  The users do not know still an error has occurred or that their database changes have been successfully saved until they literally put you at the bottom of the page.

    My page happens to have several regions (HTML, report, form) some of which are "children" of the parts of 'parent '.  It's just the way I need to position the different regions on this particular page.

    If anyone knows why these messages appear at the bottom of the page?

    I want to display them all at the top of the page.

    Any son of tips/suggestion how to control the placement of the message on a page would be much appreciated.

    Thank you.

    Elijah


    The placement of messages are defined in the page template.

    If anyone knows why these messages appear at the bottom of the page?

    You put your regions in a position in the region above the location of the messages.

    Change one of the regions and in the "User Interface" section, there is the field "View Point".  Click on the flashlight icon to the right of this field to see a presentation of the positions of the region and location of the messages.  Note that #SUCCESS_MESSAGE # and #NOTIFICATION_MESSAGE # are under some other positions (e.g. region Position 1 and Position 4 region) region

    Parts of the main body of a page are normally in "body of Page Template (3).  Try changing your regions for the "body of Page Template (3)" shows point.
