Component attribute declarative ADF back scope of bean

• Component attribute declarative for action in the link layer

  Hello
  
  I have a component declarative which includes buttons to add/remove/save/cancel that I hope to use to the standardization of page layouts. I need to assign two properties for each button, the actionlistener and the enabled property.
  
  For the button of validation for example I would attribute actionlistener for * #{bindings.Commit.execute} * and I would set the enabled property to * #{! bindings.Commit.enabled} * which would allow the validation button only if there was something to engage, if the action of CreateInsert had been carried out for example.
  
  And I would create attributes in the declarative element to these two parameters.
  
  What I want to know is is there a way that I can pass the action itself #{bindings.Commit} as an attribute in the component declaration so that I can reduce the number of attributes (and ease of development), and if yes, what type this attribute will be.
  
  Thank you

  Hello

  Create an attribute of type OperationBinding (full path) and you're good to go. I did the same thing with the DCIteratorBinding

• [ADF, JDev12.1.3] UI component: when link (to a variable of bean), its value and when to link UIC together?

  Hallo,

  in lots of examples that I have seen that sometimes the whole (through the Binding property) UI component is bound to a variable of bean and sometimes only the value property is bound to a variable of bean.

  I understand that when it comes to the UIC connection on the Value property value is sufficient.

  But I ask myself... which is the approach recommended in general?

  And is there a situation in which the binding using the Binding property must avoid?

  I have created a search custom form with the field (inputTexts, checkboxes,...) the values are handled in a bean. Which would be, in this case, the approach of linking advisable?

  Thank you

  Federico

  But I ask myself... which is the approach recommended in general?

  You should almost always use concrete goods (such as the ' value')

  In some cases, you will need to update some components of the user interface programmatically (with AdfFacesContext.getCurrentInstance () .addPartialTarget (component)), and for this you need reference to any component.

  But even in this case, you can use another approach to get the reference of the component instead of binding to the beans (but of course, "binding" attribute is the best way to get the reference of the component)

  See also: that binds the JSF component? When it is best to use? -Stack overflow

  And is there a situation in which the binding using the Binding property must avoid?

  -If you do not need any component

  -If you have scope of pageFlow/view/session bean

  I have created a search custom form with the field (inputTexts, checkboxes,...) the values are handled in a bean. Which would be, in this case, the approach of linking advisable?

  Probably the "value" property

• Help on adf taskflow scope

  Hello
  I use 11.1.1.4 JDeveloper and ADF - BC in my application.
  In one of my modules, I have the following scenario.
  
  I have a stubborn workflow and a page fragment [ex: mainTabs.jsff] on this subject. I recorded a support with scope pageFlow bean and some name [ex: mainTabsBean].
  In the mainTabs.jsff file, I have four tabs. [I need to show the separate table in each tab] and two buttons save and cancel.
  So I created 4 taskfows with the corresponding jsff files and in all 4 taskflows, I recorded the same bean support as above and with the same scope [scope pageFlow and the name "mainTabsBean"]
  I slipped and fell these taskflows as of the regions in the mainTabs.jsff in showDetailItem for tabs corresponding tags.
  
  I want to have the same instance of 'mainTabsBean' used in the mainTabs.jsff as well as the tab pages.
  But instances happen differently from mainTabs.jsff-> button Save and subTab.jsff-> action.
  
  Please advice where I am doing wrong or who brought to use in this case.
  
  Kind regards
  Praveen

  Suresh,

  This wont work.

  Praveen,

  pageFlowScope is an isolated scope that is individual for each workflow. If you want to share a bean, you must pass a handle to him as an input parameter. So, if your workflow have an inputParameter

  bean--> pageFlowScope.theBean

  then you can access it from #{pageFlowScope.theBean} in the fragments of the page.

  When you set up the region of the parent page, you use EL to access the managed bean it and pass it in the workflow

• error "Ibsta" no was not declared in this scope

  I have a "error: 'Ibsta' was not declared in this scope."

  I try to program with C++ and GPIB test equipments, but so far, I have this problem.

  I'm sorry, but my knowledge of C++ is very limited because I took a module on it for about 4 months in College and now I have to rectify emergency for my project. Any help would be much apprciated, I tried searching the forums, but I still have to find an answer. I think it has something to do with my linker.

  It will be something else?

  qml->setContextProperty("_battery", &batteryInfo);
  

  for example

  qml->setContextProperty("_bateria", &batteryInfo);
  
  or
  
  qml->setContextProperty("Battery", &batteryInfo);
  

• error: 'QmlDocument' was not declared in this scope

  I followed along the following:

  https://developer.BlackBerry.com/Cascades/documentation/UI/integrating_cpp_qml/index.html

  And added the following code to main.cpp:

  #include 
  #include 
  
  #include "app.hpp"
  
  using ::bb::cascades::Application;
  
  int main(int argc, char **argv)
  {
      Application app(argc, argv);
  
      QmlDocument *qml = QmlDocument::create("main.qml");
      AbstractPane *root = qml->createRootNode();
      Application::setScene(root);
  
      return Application::exec();
  }
  

  When compiling, I get the error:

  error: 'QmlDocument' was not declared in this scope
  

  Your weird namespace.

  using bb::cascades;

  Try this.

  Edit: Also if I were you I wouldn't want to create a new project and select HelloCasades as a model.  That will be running a lot faster than to try to do it from scratch.

• Toast not declared in the scope

  Hello

  I am going through the updated documentation and having problems of implementation of the toast.

  void App::showToast() {
      toast = new SystemToast(this);
      toast->setBody("Welcome to the BlackBerry 10 Cascades documentation!" + "You have lots of space, but your text will wrap around in the dialog box.");
      toast->show();
  }
  

  Returns an error: "toast not declared in the scope" on this line:

  toast = new SystemToast(this);
  

  I've added all these header files to my name .cpp

  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  #include 
  
  using namespace bb::cascades;
  using namespace bb::system;
  

  My .pro includes these:

  LIBS   += -lbbdata -lbbsystem
  

  My header app.hpp file looks like this

  // List with context menu project template
  #ifndef App_HPP_
  #define App_HPP_
  
  #include 
  
  namespace bb { namespace cascades { class Application; }}
  
  /*!
   * @brief Application pane object
   *
   *Use this object to create and init app UI, to create context objects, to register the new meta types etc.
   */
  class App : public QObject
  {
      Q_OBJECT
  public:
      App(bb::cascades::Application *app);
      virtual ~App() {}
      void showToast();
  };
  
  #endif /* App_HPP_ */
  

  Have a blast to find out why its not working. Anyone of you has a working example that connects everything to display a simple toast?

  Thank you

  I guess you missed the variable declaration.

  Declare an SystemToast object in the method itself or in app.hpp like this:

  SystemToast *toast;
  

  Kind regards

• SqlDataAccess has not declared in this scope

  Learn how to use SQL statements in the Cascades.

  I'm following the example provided in https://developer.blackberry.com/cascades/reference/bb__data__sqldataaccess.html

  I copied the code example in my app.cpp and consisted of two instructions include:

  #include 
  #include 
  

  Here is the code

  // create a data model with sorting keys for firstname and lastname
  GroupDataModel *model =
    new GroupDataModel(QStringList() << "firstname" << "lastname");
  
  // load the sql data from contacts table
  SqlDataAccess sda("contacts.db");
  QVariant list = sda.execute("select * from contact order by firstname");
  
  // add the data to the model
  model->insertList(list.value());
  
  // create a ListView control and add the model to the list
  ListView *listView = new ListView();
  listView->setDataModel(model);
  

  When I compile I get the following:

  ../src/app.cpp:21:5: error: 'SqlDataAccess' was not declared in this scope
  

  What I am doing wrong?

  Thank you!

  SqlDataAccess is located in the bb::data namespace.

  Also, need to add the line:

  LIBS += -lbbdata
  

  in *.pro in your project file. See here:

• another namespace issue? 'CameraSettings' was not declared in this scope

  I have a camera native c ++ application coded and run successfully.

  I want to change the flash mode.  So I add:

  CameraSettings* cameraSettings = new CameraSettings();
   cameraSettings->setFlashMode(CameraFlashMode::Light);
   camera->applySettings(cameraSettings);
  

  I also add:

  #include 
  #include 
  

  When I build, I get the error:

  'CameraSettings' was not declared in this scope.

  Is it a matter of namespace or a:

  LIBS += ?
  

  ... question?

  Something else?

  My current LIBS:

  LIBS += -lcamapi -lscreen
  

  I see what is happening, I mix with QT c functions.

  I need to use the settings as shown in this example:

  I get the error:

  setScene has not declared in this scope.

  Any ideas how to fix?

  Hello

  You must use following syntax to define the method of application setScrene.

  NavigationPane * rootPane = qml-> createRootObject();

  Application::instance()-> setScene (rootPane);

• Is it possible to create a shuttle component in Oracle ADF, where the available and selected lists are tables of the adf?

  Hi all

  
  

  We use JDeveloper Studio Edition Version 12.1.3.0.0 and deployed on GlassFish Server Open Source Edition 3.1.2.2 (build 5) and connect to the SQLServer database.

  
  

  Is it possible to create a shuttle component in Oracle ADF, where the available and selected lists are tables of the adf?

  
  

  
  

  I did a POC sample on it. I can share with you. I can't put in my dropbox because dropbox is blocked in my network. Share your email. I'll send the POC through

• How to reference an attribute binding in backing bean

  Hello
  
  is there a way to refer to a binding attribute in backing bean (e.g. CustomerVO1.CustomerId)?
  I need to fill out a parameter with the value of CustomerId in a pod of support.

  Hello

  You must get the iterator:

  DCIteratorBinding iter =
  getDCBindingContainer () .findIteratorBinding (name);

  Then you can get the current line like this:

  Line currRow = iter.getCurrentRow ();

  And the value of the attribute as follows:

  Object attribute = currRow.getAttribute ("nameOFAttributeAsInViewObject");

  Kind regards
  Dimitris.

• ADF-backing beans of debugging

  Hello
  
  I'm telling us an existing application of ADF for my development and find it somewhat difficult to debug.
  
  Is it possible to debug the application with backnig beans. When I set debug points on the back of beans, the control does not prevent that. Even to the constructor.
  
  Kind regards
  
  Amit

  Amit,

  I tried to do once or twice (actually a few thousand times) and it works fine.

  Looks like it's maybe time for you to submit a test case with Oracle supports, maybe.

  A suggestion-why mark you the thread as "resolved", when apparently is not? I posted a follow-up in the other thread that you opened with the same exact issue.

  Hi Katie,

  -If your columns in the table don't vary, so you can create a POJO with all of these attributes and prepare an arrayList/table and bind it to the value property of the table
  -If the columns of the table vary, you can then follow the sample code posted in [this forum post | http://forums.tangosol.com/forums/thread.jspa?threadID=977749&tstart=30].
