• difference between the binding context and link container

  Hello experts

  can you please explain to me the difference between the binding context and link container.

  I searched on the net but unable to understand the concept.

  Hello

  the BindingContext represents the DataBindings.cpx file execution and is a record of BindingContainers and their mapping pages and views. In addition it contains information about the data used by an application controls. The link container is the representation of the execution of the file PageDef and gives you access to the collections, methods, and attributes of the data used by a page or view. Context binding is a house while the link container is a piece in.

• Accessing the context property of main.qml to a custom list in a file item separate qml

  Hi all

  Sorry if this is already covered somewhere.

  I currently have an application with a list view in my main.qml.  I put a context property for my class app c ++ to be "app" in my main.qml.  My list uses a custom list item that is defined in a file separate qml.  The custom list item has a popup menu.  In this context menu, I want to call Q_INVOKABLE functions that are part of my class from the main application in C++.  What is the best way to be able to do?  Should I just set the context property on my file qml of list item custom like I do with my main.qml or is there a better way?

  Thank you

  I think that this has been repeated several times, but as it is not really intuitive:
  a listitemcomponent lies in a different context, it cannot access the context property of the qml file.
  You can use the reference to the listview to reach outside, see https://developer.blackberry.com/cascades/reference/bb__cascades__listview.html ListItem.view

• JDeveloper ADF Mobile - Android context

  Hello
  
  I'm new to the development of the ADF Mobile. I wanted to use an existing library of android. which requires the context as a parameter because this isn't some back-end database activities. How can I get the Android context if I develop hybrid application using ADF Mobile.
  
  It's very urgent for the development of mu. Any help is appreciated.
  
  Kind regards
  Kathia

  Hi, unfortunately I don't think that it is easy to use an existing library of Android, because the JVM Dalvik on Android device is different from the JAVA virtual machine integrated into ADF Mobile. ADF Mobile integrates its own JVM to ensure cross-platform compatibility.

  However, that said, what is the use case exact application you have in mind? In the backend, you mean you are trying to use the Android library communicates with the database server and synchronize data and download data in the local SQLite Database?

  Thank you

• Element of the ADF: access attribute a component when it is inside a foreach statement

  I have the following components:
  
  < af:foreach >
  < af:table binding = "#{BackingBean.table}" >
  < af:outputtext rendered = "#{BackingBean.table.activeRowKey eq thisRow}" / > "
  < / af:table >
  < / af:foreach >
  
  
  When there is only one table, it works fine.
  However, when there is more than one table, for all tables, BackingBean.table.activeRowKey always returns the actieRowKey of the last table.
  
  
  I need either to have a smart link who knows which table to return whenever I'm back there, or a way to get rid of the link by doing something like this:
  
  
  < af:foreach >
  < af:table >
  < af:outputtext rendered = "#{parentComponent.activeRowKey eq thisRow}" / > "
  < / af:table >
  < / af:foreach >
  
  The problem is that I have not found a way to get the parent component by using an expression EL (parentComponent.activeRowKey)
  
  Any Suggestions?
  
  Thanks in advance!

  Hello

  a table can have a defined selectionListener. He points to a managed bean. As the selection event, you have access to the item (table). I think that should do the trick

• Access to a Java servlet class

  Can make a servlet running on the access of the server has a class defined on server B?
  More information:
  I am new to Java servlet programming and want to make sure that my web application is secure. I've implemented a Java class that returns information from the user (name, address, e-mail etc.) and I put in place of the jsp and servlet pages that access the class through a 'import my.class...» "for servlets and a ' @page import ="my.class... ". ' 'for the jsp. Pages jsp and servlets do session verification and authentication, but the class has nothing of all this - it's methods simply return the requested data. I don't want to put all the identifications in the class, but I want to make sure that there no way to other web servers out there on the internet could access this class in my web application. I don't think it is possible, but my fear is that some hacker out there could do it somehow remotely a @page import "my.class...". "on my Web server and then access my methods of the class? These web applications are run within a Glassfish 3.0 application server.
  
  Thank you!

  No.. Servlet running on a server can not access anything on server B that are not accessible via HTTP.
  Your class/jar files (and in fact anything under the WEB - INF directory) are not public.

  In fact, if you have WebApplicationA running on the server has WebApplicationB on the same server cannot access the WebApplicationA classes.

  You should not have problems of security in this regard.

  see you soon,

• Cannot access the context Menu to add input/output formula node

  It is a weird problem. I can't access the menu shortcut in the node of the formula. I right click on the border, nothing happens. Someone at - it will meet it before? Is there another way to add entries and exits?

  I'm running Vision Builder AI and want to use a formula node in my calculator.

  Found.

  In the configuration settings, there is an entry that is default 'hideBDPopupMenus = True'... changed to false and the menu pop.

  Thanks for your help.

• Can not access the context property of the Interior of the ListView checkbox - onCheckedChange event

  I have a context property called "app" that connects to my C++ application. My listview has a box with onCheckedChange event listener. In this method, when I make a call to the C++ side. application app.runAction, the system displays not found error app.

  If I move the box outside the list view, it will correctly trigger app.runAction.

  Can you please take a look? Thank you!

  On the side of C++ on how I set the context property.

  QmlDocument * qml = QmlDocument::create("asset:///main.qml").parent(this);

  If (qml-> {hasErrors())}
  Returns false;
  }

  QML-> setContextProperty ("app", this);

  navigationPane = qml-> createRootObject();
  If (! navigationPane) {}
  Returns false;
  }

  QML side

   

  NavigationPane {}
  ID: nav

  {Page}
  ID: mainPage
  {Of container

  {To ListView

  listItemComponents:]
  {ListItemComponent}
  type: 'point '.
  {Of container

  Checkbox {}
  Determine whether the check box should be checked
  According to a value in the data model
  checked: ListItemData.checked
  onCheckedChanged: {}
  app.testAction ();
  }
  }

  This is a scope issue... I really hope the devs find a way to fix it properly apart from this ugly solution:

  You can solve this problem by setting your app variable in the global object Qt

  NavigationPane {
      id: nav
  
  onCreationCompleted: Qt.app = app
  
  Page {
          id: mainPage
          Container {
  ListView {
  listItemComponents: [
          ListItemComponent {
                          type: "item"
                          Container {
                     CheckBox {
                                  // Determine whether the CheckBox should be checked
                                  // according to a value in the data model
                                  checked: ListItemData.checked
                                  onCheckedChanged: {
                                       app.testAction();
                                       Qt.app.testAction();
                                  }
                              }
  

  all code in a ListItemComponent will suffer from this 'framing' question

• Can not access the context in QML property

  So I have an arraydatamodel in the CPP file, I use qml-> setContextProperty (...) to set it up to allow QML to access, the strangest part is, no matter if I put it in navigationPane Page or a container, it keeps saying can't find not variable, but in the same QML in ListView, they can access it without a problem. The other weird part, it is an another QML is able to access it in the tag of the page, the same model.

  Now the problem is, I have a 'Create a new Action' button, click on one, I can insert a new row in the table of 'Action '. Given that I have converted this column 'ActionId' in a command link, I couldn't enter any value in the newly created row. While I can give values for the other columns and save the changes.
  
  Please tell me some idea, so that I could use the field "Actionid" such as CommandLink and also support of editing operations.
  
  
  Thanks in advance,
  Sabarisri. N

  Try adding the switch to display inputText for insert and commandLink for update.

  Sample:

  
    
        
    
    
    
        
        .
        .

• How to access all the lines one by one, a table ADF via managed bean

  Hi Experts,
  
  Hi I'm new in the ADF.
  
  Could someone help me to fix the case below?
  
  Scenario - I have a table called Test_T1 that have 4 columns C1, C2, C3, C4. Creation of EO, VO and AM for test_t1.
  When created in pages ADF, I selected the option "automatically exposed components UI in new managed bean" (mynewmanagedbean.java).
  Control data drag and drop Test_T1 table in the page as a table of the ADF.
  Set the properties is read-only C1, C2, C3 and C4 is an input text.
  Add after the table and attathed button action on the mynewmanagedbean.java bean managed.
  At the time of the Test_T1 page filled with a few No.. lines (such as 9).
  How can I access all the lines above through the key without selection of these.
  In fact, I want to print all the rows of the table in the log at the time to press the button.
  
  Thanks in advance.

  Sorry for the delay, the code was copied from another test case. You can work directly with the line...
  I created a new test case based on the departments of the HR schema table:

  import oracle.adf.model.BindingContext;
  import oracle.adf.model.bean.DCDataRow;
  import oracle.adf.model.binding.DCBindingContainer;
  import oracle.adf.model.binding.DCIteratorBinding;
  import oracle.adf.share.logging.ADFLogger;
  
  import oracle.jbo.Row;
  
  public class DumpRows
  {
      private static ADFLogger _logger = ADFLogger.createADFLogger(DumpRows.class);
      public DumpRows()
      {
      }
  
      public String cb3_action()
      {
          DCBindingContainer bindings =
          (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
          DCIteratorBinding dcIteratorBindings =
          bindings.findIteratorBinding("DepartmentsView1Iterator");
  
          // Get all the rows of a iterator
          Row[] rows = dcIteratorBindings.getAllRowsInRange();
          for (Row row : rows) {
              String depname = (String)row.getAttribute("DepartmentName");
              _logger.info(depname);
          }
          return null;
      }
  }
  

  As you do not have the class of line interface build you must get the attributes in their names. Be careful here, because any misspelling is cought only when you run the application.

• Access to the instance of the Application Module to the users of servlet

  I have a servlet that is required to access the current users request module instance.
  
  I added the servlet to filter "adfBindings" to access links in the servlet.
  It works very well. I can access all the links in the servlet.
  The security context of the user is also available.
  But the servlet always creates a new instance of request for a user module.
  I tried several ways to access the module of the application.
  
  I need the servlet to access the actual instance.
  I tried to also pass the State "_adf.ctrl" for the servlet, but without success.
  
  Is there a way to access the current instance of request module in a servlet?
  
  Thanks for your help!

  I use JDeveloper 11.1.1.3.0 (JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660)

  You can do it. The idea/solution is Jan Vervecken and works as far as I tested it.
  You need build a URL pointing to your servlet with a parameter to transfer the current DataControlFrame. In the servlet to read the parameter and uses it to obtain the current DataControlFrame.

  You can find the thread here what createRootApplicationModule() must be called from a servlet?

• session or the servlet context

  Hi all
  
  Can I access values of session context and servlet in the code of people...
  
  Here I want to achieve...
  I want to store a value or a java object in the OCntext application... When the appserver is launched for the first time I want to save the java object in the session and then later I want to user the variable/object in users...
  
  
  Let me know if you have pointers...

  Your Java/class code must be stateless and can take this value as a parameter. Whenever you want to use the Java object, you will need to pass the value of the global variable.

• Context of sequence of LabVIEW user interface access

  I'm trying to find a way convey the context of the sequence into LabVIEW Advanced User Interface. I need to check the values of some globals to the station before opening a movie file.

  I was looking for a way to send a UImessage to frontendcallbacks.seq that contains the context of the sequence, but I couldn't make it work. What is the best way to access the context of the sequence of the user interface?

  Hello

  In your user interface, use the Engine.Globals to get a reference to the StationGobals, then you can use the PropertyObject.GetVal and SetVal to read or write to the necessary StationGlobals.
