Embark on an application module is also committed the other

Jdev 11.1.1.4

I have a fusion ADF application where I defined two data controls.

One is called AppModuleDatacontrol and the other AppModuleWSDataControl.

I do this in order to devote DML made on a data control independently of the other.

The problem is that when one do something like:

AppModuleWSImpl am = (AppModuleWSImpl) Util.getApplicationModule ("AppModuleWSDataControl");
am.getTransaction () .commit ();

Errors on VO de AppModuleDataControl are triggered. They shouldn't be triggered!

I've activated ADF newspapers and just after the execution of

AppModuleWSImpl am = (AppModuleWSImpl) Util.getApplicationModule ("AppModuleWSDataControl");

and before running the validation I get:

< A > < findDataControl > BindingContext [4147] INFO: no refreshRegion, jumping cpx codebase research AppModuleWSDataControl
< BindingContext > < set > [4148] BindingContext.put (AppModuleWSDataControl@edu_esade_view_DataBindings_cpx, oracle.jbo.uicli.binding.JUApplication)

< DebugDiagnostic > < print > [4154] DBG: DataControl: looking at: _adf_dc_user_params_key_
< ADFLogger > < start > create the Application Module nested


I don't know if "Create nested Module of Application" is important, but I don't want this AppModule nesting on the other. I want them to be completely independent in order to achieve independence, the actions of validation.

Any help?

"1.Defining all BTF as 'No operation controller'" I can assume that the two AppModule will still work with different transactions ".

As long as they are defined as separate root AMs and you used the option of they will work with db connections, so different transactions too.

"and a transaction in an AppModule persist hollow pages.

In the context of a BTF Yes. In the scope of BTF chained which depends on the BTF data control box option. If you set which isolated, each instance of a BTF will create a new instance of the AOS in question (and new connections/transactions with the database). If you use shared, 1 instance of the AM will be shared (1 connection/transaction).

' 2. what impact this can have by reusing BTF? I have a page jsf reusing the same workflow in the two regions. The taskflow performs initialization. The unwanted parts will interact with the other? »

It depends on the option given extended control as specified above. If you want them to be independent, use scope of control options data isolated on the BTF.

  • Application module tries to access the secure API

    Hi all.

    We are new to Blackberry Java development and have some problems with it.

    We use the same BlackBerry Bold 9000 and OS worm Simulator. 5.0 in Eclipse JDE.

    The JDE version is 5.0.0

    We signed HelloWorldDemo with tool of power, provided by BB. It worked fine on the Simulator AND the device.

    Then we signed our own application, based on PictureScrollFieldDemo.

    The thing is, on the simulator of OUR application works fine, but when we try to run on the device, it failed with an error that says something like this: "Application module tries to access the secure API."

    After that many times we tried to remove the code all potentially dangerous and recompile the application. After that it stopped working at all (when you click on the application menu, ABSOLUTELY nothing happens).

    Then, we decided to try to launch PictureScrollFieldDemo, the sample provided by BlackBerry. Also, it did not work

    Finally, the HelloWorldDemo has stopped working or the other...

    During all this madness, we rebooted the unit several times.

    Please help, appreciate any advice.

    Thanks in advance, geezmo.

  • Creative applications of Cloud also from the trial? Try this!

    I just wanted to share a possible solution to the problem of the trial version that many people seem to feel. The whole topic is very confusing, because there seems to be a problem of trial that is specific to Photoshop (probably set by the last update), and then there are cases where all applications from the Application Manager think they are trial versions. This question was pestering me for two weeks now and today I came across something that suddenly solved the problem - at least for me.

    Actually, all I had to do was to install a new application from the Application Manager (what was not installed before - in my case it was the Flash). I wanted to check if a newly installed application would fall also in status of the trial directly after installation and what happened was, he did not. What happened, is that all other applications returned to their normal behavior. More no test pop-up windows!

    I just install a new application somehow forced the Application Manager to check my subscription status in a way that would not make a normal connection. The solution persited after a restart of my computer so my hopes are high that this solves the problem permanently.

    I'm curious to know if this could help someone else.

    Install the latest version of Photoshop (13.0.4 or 13.1.2) should solve the problem. It may also be necessary to make the software, once again, click on the button "license this software" and sign in using your Adobe ID we also have this document on the issue.

    Trial opens at the launch

    I like my list of tab bookmarks to organize and do not have the same website to be double time

    When you create a bookmark, it will be shown in 2 places, there is no overlap of the bookmark, and then coming in "recently bookmarked" is as an index of the most recently created bookmarks:

    • the regular bookmark
    • the automatic query of your existing bookmarks in "recently set bookmark".

    When you create a bookmark with a tag, the tab will be shown in 2 places, there is no duplication with the bookmark or tag, the recent "Tags" is like an index of latest brands:

    • the regular bookmark
    • the automatic query of your bookmark existing "recent Tags".

    My only suggestion is, if the smart folders "Recently set bookmark", "Most visited" and "Recent Tags" are concerning you or creates confusion for you, you can right-click on these files, individual items not in these three files, but the files themselves and choose Delete. Then you need more these 3 smart folders showing and that can end your confusion about the smart folders.

    I don't have any other suggestions or information for you, as it appears that you have either not well read or understand not smart folders that I posted earlier, or information we are not 'communicate '.

  • The best way to find the name of the installed application module?

    If you don't know the name of an application module, how can you find it?

    For example, if I have the name of jad file from another application, can I assume that the name of the application module is basename of the jad?  As in, a name of jad MyApp.jad would result in a module name to 'MyApp '?

    That was my assumption in a first time, and it of that he seems to be the case, most of the time, but not all.  In particular, if the jad's name:

    MyApp - 1.0.0.jad

    I found that the name of the actual module on a "BOLD" v4.6.167 running (and the 4.6.0 JDE the bold Simulator) is

    MyApp$ 2 d 1

    However, * on an another "BOLD" * (this a v4.6.0.162 running), the exact same application indicates a module name of

    $ 2 d $1 2e0 MyApp$ 2e0

    That's why I wonder if there is way to get more definitive an application module.  I scoured the API documentation and the solution isn't jumping home.

    Thoughts?

    Thanks for any help.

    Ah.  I can also see if I need to 'escape' my module names.  If this isn't the case, then I can watch an exact match in the list of module names.  If I have, it seems that I still need to look for something, "close enough" and hope for the best.

  • Cannot find the Application Module

    Hello experts!

    I extended a controller to validate a user input (controller: oracle.apps.ar.cusstd.contact.webui.ArAcctContactCreateCO).
    I clicked on the about Page and in the PageDefinition the pageLayout controller = ArAcctContactCreateCO and ArContactsAM = application module.
    When I scroll I find attribute I'm posting called PersonLastName. This attribute is under
    controller: HzPuiQuickCreatePersonSpecialCO
    AM: HzPuiQuickCreatePersonAM
    VO: HzPuiPerQuickCreateProfileVO
    Display attribute: PersonLastName


    It's my extended controller:

    package xxx.oracle.apps.ar.cusstd.contact.webui;
    Import oracle.apps.fnd.framework.webui.OAPageContext;
    Import oracle.apps.fnd.framework.webui.beans.OAWebBean;
    Import oracle.apps.ar.cusstd.contact.webui.ArAcctContactCreateCO;
    Import oracle.apps.fnd.framework.OAApplicationModule;
    Import oracle.apps.fnd.framework.OAException;
    Import oracle.apps.fnd.framework.OAViewObject;
    Import oracle.jbo.Row;


    SerializableAttribute public class XXF5ArAcctContactCreateCO extends ArAcctContactCreateCO
    {
    ' Public Sub processFormRequest (OAPageContext oapagecontext, OAWebBean oawebbean)

    System.out.println ("AM:" + oaapplicationmodule);
    OAApplicationModule PersonAM = (OAApplicationModule) oaapplicationmodule.findApplicationModule ("HzPuiQuickCreatePersonAM");
    System.out.println ("PersonAM:" + PersonAM);
    }
    }

    For some reason, the computer cannot find HzPuiQuickCreatePersonAM application module. I get the following results:
    PFR running
    AM: oracle.apps.ar.cusstd.contact.server.ArContactsAMImpl@5b04ae
    PersonAM: null


    I also replaced OAApplicationModule oaapplicationmodule = oapagecontext.getApplicationModule (oawebbean) with OAApplicationModule oaapplicationmodule = (OAApplicationModule) oapagecontext.getRootApplicationModule () and I got the same results.

    Does anyone know why it does not find HzPuiQuickCreatePersonAM application module? Any help is appreciated.

  • JUnit test of an ADF application when you have nested application modules

    Hello

    When you set up a device for JUnit test in the model of the ADF, and you have nested application modules, there are advised to have a class of the device for each module of the application, or create a luminaire of class for the root application module and access somehow nested those there for view objects you want to test JUnit , or have a luminaire of class and somehow reference the individual nested application of this class modules? Everything I've read about JUnit test of an ADF application only shows an application module in the template project.

    Thank you.

    I have used with success that one category of luminaire for my application module root, and then in my test case files I can reference the application embedded this suff module.

    Example:

    The TestAMFixture.java file is where you describe the application module you want to use. This file and others, is what is generated when you let JDeveloper create your Business Component Test Suite (chosen from the New Gallery):

    The constructor of this file is where the application module is defined:

    public TestAMFixture() {}

    _testAm = Configuration.createRootApplicationModule (amDef, Config);

    }

    In my test for the projectVO scenario file, I'm testing a required attribute in a display object, so I need to access the view object that is in a nested application module:

    ViewObject _projectVO = fixture1.getApplicationModule () .findViewObject ("ProjectAM1.ProjectVO1");

    fixture1 is a reference to the TestAMFixture class. getApplicationModule() is a method in this class that returns the application root module I set in the TestAMFixture constructor. ProjectAM1 is the nested application module and ProjectVO1 is the view object where the attribute is that I will test.

    For a better explanation, please see these references, I used.
