• Could not create collectionModel to be bound for ADF Table in Backing bean

  Hi Experts,
  My version of JDev is 11.1.1.6.0.
  I need to bind the ADF table with a collection of items using backing bean.
  My grain of support consists of 6 channel lists, where each list represents a table column. How can I fill the entries in the table with these lists.
  
  When I drag "* Table *" component on my jsf page, he asks "* Table Data Collection *" be bound. Please help me in creating a collection.
  
  My job is stuck because of this, can someone help me by giving instances of backup files bean and jsf.
  Give me a very clear example for that.
  
  Thank you

• How to develop the Table of Backing Bean tree nodes?

  I have a requirement where I want my table to be expanded all three nodes. InitiallyExpanded = True develops alone.
  Is it possible to have all the Backing Bean nodes?
  
  Code snippet will be very useful.
  
  Thanks in advance,
  TK

  For all nodes in a treetable can be expanded, you will need to add all the rows of the disclosedRowKeySet.

  (1) create a binding for the treetable in average managed code as "treeTable.
  (2) create a CommandButton named "Expand" (under the picture of the tree) and Visible set to false and create a link to a page named expandButton & in the get accessor for the commandButton control method, call the following method:

  public RichCommandButton getExpandButton() {}
  this.expandTreeTable ();
  }

  private RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();

  private void expandTreeTable() {}
  If (this.treeTable! = null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  Model CollectionModel = (CollectionModel) treeTable.getValue ();
  JUCtrlHierBinding = treeBinding
  (JUCtrlHierBinding) model.getWrappedData ();
  JUCtrlHierNodeBinding RootNode = treeBinding.getRootNodeBinding ();
  disclosedTreeRowKeySet = treeTable.getDisclosedRowKeys ();
  If (disclosedTreeRowKeySet == null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  }
  List = firstLevelChildren
  rootNode.getChildren ();
  for (node JUCtrlHierNodeBinding: firstLevelChildren) {}
  List ArrayList = new ArrayList();
  List.Add (node.getRowKey ());
  disclosedTreeRowKeySet.add (list);
  expandTreeChildrenNode (node, treeTable, list);
  }
  treeTable.setDisclosedRowKeys (disclosedTreeRowKeySet);
  }
  }

  Private Sub expandTreeChildrenNode (RichTreeTable, rt,
  JUCtrlHierNodeBinding node,
  The list parentRowKey) {}
  ArrayList children = node.getChildren ();
  List rowKey;
  If (children! = null) {}
  for (int i = 0; i)< children.size();="" i++)="">
  rowKey = new ArrayList ();
  rowKey.addAll (parentRowKey);
  rowKey.add (((JUCtrlHierNodeBinding) children.get (i)) .getRowKey ());
  disclosedTreeRowKeySet.add (rowKey);
  If (((JUCtrlHierNodeBinding) (children.get (i))) .getChildren () is
  null)
  continue;
  expandTreeChildrenNode (rt,
  (JUCtrlHierNodeBinding) (node.getChildren () .get (i)),
  rowKey);
  }
  }
  }

• GetCurrent line table in Backing Bean - strange behavior

  My application is a collection of user data form. It is a front-end for the provision of new users in the ERP system.

  On my main page, I have a table read-only and I'm trying to get the selected row in this table. The binding is a read-only view object based on a SQL query that accepts an id as a parameter (necessary for performance reasons). The yasmina is filled on a partial trigger of a SelectOneChoice component.

  First, I built a few apps poc to test the feature but currently without the variable binding

  So in my POC using this code

  DCIteratorBinding locationIterator = bindings.findIteratorBinding("LocationsViewIterator");

  voRowData = locationIterator.getViewObject ();

  rowSelected = voRowData.getCurrentRow ();

  personal.setFirstName (rowSelected.getAttribute("ApproverName").toString ());

  I can quite happily retrieve the selected line.

  In my application, however whenever I try to access the selected line on the table in my page I always returned the first row of the iterator

  The selection of lines is set to Single.

  Someone has encountered such a problem before or possibly what have I not put?

  Thank you

  Owen

  For anyone with a similar problem, I finally found a solution...

  My first solution to my opinion single reading required passing a variable binding in front of a drop-down list box. It was around performance for serious reasons as the query in the query has been quite complex.

  But with a little work, the query runs much more efficiently.

  So now I have 2 objects in the view read-only. One for my SelectOneChoice and one for my table. I created a link between the two so I have a connection between my SelectOneChoice and my table.

  It is all so much more easy when you know the answer.

• Do select table to backing bean

• Get the value of the bind variable in backing bean class VO Impl

  Hello
  
  I have a VO that includes a bind "pOrgId" variable, the VO has a java VO Impl class that includes:
  
  /**
  * Returns the value of the variable to pOrgId.
  value of the variable * @return for pOrgId
  */
  public {getpOrgId() number
  return (Number) ensureVariableManager () .getVariableValue ("pOrgId");
  }
  
  So it is possible to obtain the value is concluded by the binding variable using this class in a backing bean? (I tried to import the VOImpl class in the bean to support, but getpOrgId is not available?).
  
  (JDEV 11.1.2.3.0)
  
  Concerning
  Carl

  Hello

  When you create a ViewObjectImpl class, none of these options is to generate the getter/setter for bind variable. Create a client class interface and expose the get method for the variable binding. Now, you can reference the method since a binding method in the ADF, which you then access a managed bean by calling

    BindingContext bctx = BindingContext.getCurrent();
    BindingContainer bindings = bctx.getCurrentBindingsEntry();
    OperationBinding oper = (OperationBinding) bindings.get("name of the method binding");
    Object returnVal = oper.execute();

• 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.

• [Beginner] Best practices for Backing Bean, data binding

  Hello world
  
  
  I followed a course of oracle in November ' Oracle Fusion Middleware 11g: Creating Applications with ADF I '
  
  Awesome, now I know what are the different parts of the framework.
  
  But now, I would go a little in depth.
  
  Here's a simple example
  
  Login page
  Backing Bean
  Session Bean
  Read only the View (the view selection) object
  Application module
  
  We have a user name and password in a table, but the password is encrypted in the column, in fact, is the checksum of the password.
  
  Here's what should be done.
  
  Login (username, password) Page-> proceed button-> to get the data of VO-> compare usernames-> transform password from the login page (MD5)-> compare him the password of database->
  assignment of params session bean-> redirect to Connexion2 page.
  
  Here's what I actually
  
  I have an AM listening with a java class having a doLogin (String username, String password) method with a return value of string.
  
  This method is exposed to the UI via a client interface.
  
  Here are my questions.
  
  Where can I check and turn all these params. In playback only VO via a class Java tuned, which extends ViewRowImpl or listening AM class java?
  
  And now for the session bean where I have to instantiate. I guess the Backing Bean.
  
  Wouldn't be better to call the client interface of the bean to support, then instantiate the session bean, with params from AOS, in this BackBean.
  
  I so much question that I don't know where to start. :-(
  
  Sincerely for your help.

  Hello

  If you want to keep the information for the duration of session, create a managed bean and configure it to session scope. If you need to access you can use EL directly or from Java in another managed bean (or bean backing) whereby the bean is instantiated. You can also use managed properties to pass the reference of a bean to support session bean.

  As for the location of the method, you must use a View object to query the user table just the user name. You read the encrypted password (assuming a single user entry is found) and compare it with the provided password. You return true/false value and use an OperationBinding in a bean managed to access the customer interface method through the ADF (action method) link layer

  OperationBinding operation = bindings.get ("login") (OperationBinding);
  operation.getParamsMap () .put ("username", username);
  operation.getParamsMap () .put ("passwd", pw);

  Boolean result = operation.execute ();

• Create table ADF on the backing Bean page

  Hello
  I am currently able to recover and iterate/modify the data of a base of the Interior of the module of the Application manually (storing the changed data in a table). How ever I don't know how to put these data from the Module to the Application page that called? I'm assuming that I need the method that is called to return an CoreTable that would be then displayed on the page. It is the right approach and how would I go to do this?
  
  Thank you
  
  
  
  Steve

  Hi Steve,.

  There are several ways to do this:

  -With the help of your:
  a. entity create and display objects to database tables and then add objects to view the module of the application
  b. drop the View object in the data as ADF Table control palette in the jspx page
  c. you can also drop some operations like CreateInsert(for insertion), remove, Commit, Rollback etc.
  d. If you want to perform operations on existing data, you can write a single method in AMImpl or VOImpl and modify the view object by the criteria of view running or where clause, then call this method from jspx page by exposing to the client interface

  -Programmatically binding value to table:
  a. create a method in AMImpl and return the records in the list and exposing it to the client interface
  b. Add the binding of the method in page jspx
  c. write a method in bean which return ListDataModel and link it to the value property of the table
  d. inside the bean method, call your AM method in getting the operationBinding
  e. give the list returned by the AM method to the listDataModel.setWrappedData method

  -You can prepare the entire table in the bean and then can link it to the table using the bindings property
  Among all the three ways, according to me, the first one is effective and simplest, you can choose one based on your requirement

• How to show a different side of backing bean using UIXSwitcher

  Hi all

  I have a requirement to clear the contents of the dialog box, and then to display the message of success on the same dialog box.

  Backing bean:

  During the click on send

  Hello
  You can binding a component and in the accessor Set put a default value {: identifier of the thread = 993252}

  Another approach is use of beforephase http://www.gebs.ro/blog/oracle/oracle-adf-select-one-choice-default-selection/

  Another is the default value of VO (only for new lines)

• Backing bean - scope pageflow

  experts,

  all are complted. but I need a value inputtext only content want to reach illustrated in another text of page output.
  
  Hold on...
  
  
  concept of pageflow tells me something like that
  
  proablay value of travel from one page to another page. It adapts.
  
  concept of backing bean teach. values of a work around page itself. not a page to another page.
  
  
  Chase now
  
  but. my much of the work was already done. with backing bean. now that an individual must travel from one page to another page.
  
  what I can do.
  
  
  If you prefer pageflow is a must. I want all change them a bit hard for me. a lot of work I have around him.
  
  I hope you understand.

  Hello..
  Yes it is possible. You must add this interface method customer of AppModule.Now you can see this method in data Controls(Refresh the data control). To call this method using bean, should be added as an action method links (click on links > + > methodAction > and create the binding of the action).
