Best practices to navigate programmatically to a page in the ADF

• Best practices for handling logic conditional dialogue/popup in the ADF?

  Here's the scenario:

  I have a page that shows a popup programmatically in a method of bean support. The popup asking the user a yes / no question and subsequent logical path is determined by their response. However, if the popup is visible or not in the first place is conditional. In addition, there is an additional logic in the original method, apart from the logic of popup, that must be met.

  The problem with this is that the ADF seems to spin off the popup in another thread and prevents the execution of logic in the original method at the same time, while you wait for the response from the user. However, the desired effect is that the program stops until the user has answered the question in the context menu.

  I was not able to understand in an elegant way to make this happen. Ideally, I think that the solution is to encapsulate the logic that occurs after the popup is displayed (or not shown) in the original method and call it from the popup action listener if the popup is displayed (if not call it the original method of). However, the logic should be encapsulated requires the use of some local variables that have been put forward for the popup to appear. There is no way to get these values to the popup action listener method to pass them on to the encapsulated logic (aside from the creation of global static variables in the bean, which seems to be a bad solution).

  Another idea I had was to get the logic ' show/do not see the popup' workflow. However, it seems that for every single popup would make the really complicated workflow.

  Is there a 'best practice' recommended to handle this situation? It must be a common problem, and it seems that I will talk all wrong.

  However, the desired effect is that the program stops until the user has answered the question in the context menu.

  This will not happen in any web environment, including ADF.

  You will have different events for each life cycle:

  1 - opening popup: popupFetchListener event

  2 - Click on OK, Cancel buttons: DialogListener event

  3 - Press the Esc button: popupCancelledEvent

  You can share data between these events on pageFlowScope, or viewScope.

  But if you use the ADF BC, you might be better to use transient attributes on the objects in view.

• Navigate to another HTML page in the same section file

  Hi all

  It is possible to navigate to another HTML page in the same file of the article? E.g. index.html contains an < a > tag has a href pointing to page2.html? This seems to work in the application of preflight in the iOS, but not in Windows. Currently I use relative links, for example

  < a href = "page2.html" > Page 2 < /a >

  Should I use a different syntax? For example

  < a href = "navto://page2.html" > Page 2 < /a >

  Thank you

  Frank

  I found the solution. Use rather JS. Windows.Location.href seems to work for ios and windows.

• Had to click twice on the page of the ADF

  I have a page in the ADF in which are some text entry fields and selectBoolenRadio fields, select a choice to enter the list of values. This form starts with all the fields in the disabled state and the user must click on a button to activate the fields to change the data. When the user clicks this button, nothing happens, when you click it once again, the action is call. I followed the beforePhaseEvent to this page and I noticed that at first (when the user makes the first click), the ADF jumps directly to RENDER_RESPONSE and when the user makes the second click, the ADF pass for all the steps correctly. I don't know what else to do to solve this problem. Please help me.

  First of all, why not use af:commandButton instead of the toolbar button?

  and the method that you use reload the entire page which is not a good practice to load the page everytime

  Place just partial relaxation on the form fields to refresh the fields (no need for this method)

  have you tried true immediately on the button?

• What are the best practices for a new employee to learn inside the instance of their business of Eloqua as efficiently as possible?

  We have companies everything changed at some point in our lives. And we all go through the process in the first weeks, where you feel new and are just trying to figure out how not to get lost on your way in the mornings.

  On top of that, trying to familiarize yourself with your new company Eloqua instance can be a daunting task, especially if it's a large organization.

  What are the best practices for new employees to learn as efficiently and effectively as possible?

  I am in this situation right now. Moved to a much larger organization. It is a huge task trying to understand all the ins and outs not only society, but also of the eloqua instance, especially when she is complex with many points of integration. I find that most of the learning happens when I really go do the work. I spent a ton of time going through the programs, documentation, integrations, etc., but after awhile, it's all just words on a page and not absorbed.

  The biggest thing that I recommend is to learn how and why things are made the way they are currently, ask lots of questions, don't assume not that things work the same as they did with your previous employer.

  Download some base in place level benchmarks to demonstrate additional improvement.

  Make a list of tasks in the long term. As a new pair of eyes, make a list of things you'd like to improve.

• Navigate to a Web page from the pictures stored outside

  I have a flash piece that chages just the image displayed on the screen. The images are stored extrenally if I can easily change out them occasionally.  It is possible to navigate to a web page, if you click on an image? If so, how is that contradict or you can direct me to where I can find how to do this? Sorry, if this is a basic question, I'm kinda a rookie.

  Thanks for your help.

  Kate

  Your stupid bet is to place the image into a movieclip and affect the code by clicking on to the movieclip.  The code you assign depends on what version of Actionscript, you use.  So depending on who it is, try searching Google is:

  «getURL AS2»

  or

  "AS3 navigateToURL.

  and you can try adding "tutorial at one of these institutions.  They can meet in the Flash help documents if you look here, perhaps with a few examples.

• Find and view a network file in the page of the ADF

  Hello

  I have a simple requirement where at the click of a button link in my page ADF, I need to display an html page stored in the network location (e.g. / / < host name > / folder1/folder2/demofile.htm)

  I have only the path and only a substring of the filename, so I have to search for the file in the network directory using this substring. Once I have the file name, I use af:goLink to navigate to the network path and view the file in the browser.

  Here is the piece of code from Managed bean and the jspx

  FindFilebean.java

  .

  .

  path = "" \< host name > \\folder1\\folder2".

  File f = new File (path);

  [] List of the files in the folder = f.listFiles ();

  File latestFile.

  for (file: filelist) {}

  {if (file. ToString(). Contains (fileNameSubstring)}

  If (latestFile== null |) ((latestFile! = null & & latestFile. lastModified() < file.lastModified ())) {

  latestFile= file ;}

  }

  }

  path = latestFile;

  .

  .

  FindFile.jspx

  < af:goLink text = "Print Traveler" id = "gl1".

  destination = "#{viewScope. . "{FindFilebean.path}" targetFrame = "_blank" / >

  < af:popup = "deferred" autoCancel childCreation = "disabled" id = "p1".

  It works perfectly fine when I run a local integrated server, but I get a null value pointeron access to the f.listFiles (); when it is deployed on the weblogic managed server

  I also tried the following:

  1. creates a servlet and tried to read the file using the buffered output stream and display in an inlineFrame

  2 FiledownloadActionListener to read the file and view/download it

  These two approaches work very well locally but display/download a blank page on the server.

  Please suggest what Miss me here and if there is another way to achieve this.

  JDev version: 11.1.2.4.0

  WebLogic Server version: 10.3.6.0

  Thanks in advance.

  In fact f.listFiles () should not throw NPE as the directory exist a lot and the code snippet works fine on the local server.

  But you should add check and display the appropriate message to the users in the case

  As you mentioned the managed server is not able to access the network share.

  Guidance on how I could do this job?

  That is the question to your system administrator.

  They need to map this network share to the managed server machine.

  Or if this is impossible, then you can perhaps use another approach (ftp, scp,...)

• How/where to store more information page in the ADF?

  Hi all
  
  What is the best way to fill the managedBean during the loading of the page?
  
  In my application, I have a page fragment that displays the details of the user of Webservice DataControl. I have and drag the data to the pageFragment webservice control. This fragment has mapped in the taskFlow and the annex taskFlow in to JSPX homepage as a region. I need to store such user information in any place (ManagedBean / or any other better place to store) that I can use at my request along, because I won't run again whenever the webservice to get the same information from the user. Also, I want to collect and store this information while I give back to the homepage, not after any action of the user.
  
  Please advice how & where to store the information in the ADF? Can I create a managedBean? If so, how to trigger this class method on page load?
  
  Thank you
  KLN

  Hello

  in this case, you configure the managed bean to be within the scope of the session. Then, on the first page, you set a stage for restoration after phase listener (it is a beacon in the f: view element). This is phaselistener refers to the bean managed using EL (important). She can do by using an expression of the method in JSF. For example, if the managed bean had a populateUserInfo method then yu might reference #{beanname.populateUserInfo} and run the expression of the method using Java. In the managed bean, the method would be to access the link layer using the BindingContext class

  http://download.Oracle.com/docs/CD/E15051_01/apirefs.1111/e10653/Oracle/ADF/Model/BindingContext.html

  Call

  . GetCurrent () .getCurrentBindingsEntry () BindingContext to get a handle of instance active BindingContainer.

  BindingContainer links is BindingContext.getCurrent () .getCurrentBindingsEntry ();.

  Then on the container of the binding, you call the method to query the Web Service for the modules

  before calling a method on the ADF link layer, make sure that the ADF is binding for the method
  OperationBinding opws (OperationBinding) = bindings.get ("name of the method exposed on the other side");
  If you need pass parameters
  opws.getParamsMap () .put ("name of the argument", value);
  OPWS. Execute();

  You can use similar code to access the information of the user of the iterator method in the ADF to complete managed bean fields. You can access user information from the bean managed through getter and setter methods

• Fax multiple pages in the ADF

  When you try to FAX several pages, I load in the ADF of my 6700 printer and start fax.

  After that some Fax pages with success, get a printout showing ERROR 346. It also indicates that a communication error occurred during the transmission.

  This doesn't seem to be a random problem, but occurs whenever I try to fax multiple pages. In addition, the same thing happens with different recipients.

  I've never run into that until I started to use my 6700 printer. Previously, when you use a fax, it never happened.

  Any help would be greatly appreciated. Thank you.

  Hello mortn99 here, I hope you enjoy your Monday

  I noticed your post on the 346 error code that you receive when you send a fax to multiple pages of your 6700 JO. Here is a screenshot of the definition of the error code and a link to the Web site to interpret the error codes in the future. The suggestion is to change the speed to slow and disable the ECM which may help you!

  See eight Solution and Solution nine to get instructions on changing the speed and disable ECM.

  Send fax fail intermittently or fails for a single recipient

  We have 2 buttons created on the Page when the page is automatically generated from a human task.
  
  The labels on the buttons are 'Insert' and 'delete '.
  We need + (in green) instead of inserting it.
  and X (in red) instead of delete.
  
  The functionality of the buttons must be identical, but simply to the user, it must be visible in the '+' and 'X' instead of 'Insert' and 'delete '.
  
  Thanks in Adv...

  Hello

  Create the sign + (in green) and X (red color) and place it in public_html

  You can set the property to the icon of the Button OK. And empty the Text property.

  JDev ADF BC 11.1.1.6.0
  
  I want to customize my page ADF for differenet of business scenarios. For example, a label displayed as 'ABC' for a user should be displayed as "XYZ" for user B.
  I mean, the label component is the same, but have different texts for different users.

  I'm also only on the security of the ADF. Let do more sample using pledge does not matter.just that you need to take care of the connection method.
  You must put this logic in your connection method where you check the user name and password.

• Dynamic display of table on the page of the ADF

  I'm looking for a page ADF that has a drop down box whose name table as inputs and when he selected should show data within this table in the ADF array element.

  Arun,

  What do you mean by "more simple? Another way to proceed would be to have fragments of JSF page separated for each table and use a dynamic region on the home page. I haven't worked through the solution, but it should work.

  Hi vbokar! ;)

  I check your application and I noticed that the political ADF seems be grayed in JDev so I re - run the Configuration Wizard for the ADF security.
  Other changes were:
  

• user "vbokar" was added to the application role 'testRole1 '.
  <>changed the password of the user vbokar for "password1" (so I can test it)
  
• changed the home page or from the success_url of ' / TestPage2.jspx ' to ' / faces/TesPage2.jspx.

  Run and Viola! It works!
