  How to navigate to the next page based on the value returned by the method call inside the action attribute of the command key.

  I use JDeveloper 12.1.2.0.0

  < af:button id = "tt_b2".

  rendered = "#{attrs.nextRendered} '"

  partialSubmit = 'true '.

  action = "#{attrs.backingBean.nextAction} '"

  Text = "next".

  Disabled = "#{attrs.nextDisabled}" / >

  private static final String NEXT_NAVIGATION_ACTION = "controllerContext.currentViewPort.taskFlowContext.trainModel.getNext";

  public String nextAction() {}

  If (validate()) {}

  updateModel();

  Return NEXT_NAVIGATION_ACTION;

  }

  Returns a null value.

  }

  Use case is made for model train, which is being implemented based on this blog: http://javacollectibles.blogspot.co.UK/2014/10/ADF-train-template.html

  We define a generic action following in the model, but the action must be called under certain conditions, based on the question of whether all validation controls had been passed on no.

  You can do this in two ways:

  1 returnValue = (String) ADFUtils.invokeEL("#{controllerContext.currentViewPort.taskFlowContext.trainModel.getNext}");

  return returnValue;

  2.

  public String getNextTrainStop() {}

  String nextStopAction = null;

  ControllerContext controllerContext = ControllerContext.getInstance ();

  ViewPortContext currentViewPortCtx = controllerContext.getCurrentViewPort ();

  TaskFlowContext taskFlowCtx = currentViewPortCtx.getTaskFlowContext ();

  TaskFlowTrainModel taskFlowTrainModel = taskFlowCtx.getTaskFlowTrainModel ();

  TaskFlowTrainStopModel currentStop = taskFlowTrainModel.getCurrentStop ();

  Terminus of TaskFlowTrainStopModel = taskFlowTrainModel.getNextStop (currentStop);

  nextStopAction = nextStop.getOutcome ();

  _logger.fine ("train, next stop:"+ nextStopAction ");

  Return nextStopAction;

• delegate method calls to the members of a class

  Hello

  I'm new to LabView and using the 2013 version.

  I am familiar with the concepts of object-oriented programming.

  situation/goal

  I have a controller that controls axes. The controller said communication happens via plain text messages.

  I want to control the two axes with orders abstract (moving, stop, speed change, etc.) of LabView.

  That's why I created a class of axis with several parameters. (although)

  The controller communication is established via an ActiveX reference.

  I created a controller class that holds said reference in addition to the two axes.

  My goal here is to create a controller object, which past its ActiveX reference for the two axis.

  To add lines to the controller I dragged the class axis from the window of the class controller twice overall project.

  I created some accessors to all members of the class of the axis, including its ActiveX reference.

  problem

  In the Set accessor method for the controller class ActiveX reference, I would like to call the setters for the return of the two axes objects that contains the ActiveX controller.

  I can separate the controller to see the two axes, but I can neither unbundle either of the axes nor can I add a method node to them.

  It is logical that the separation is not possible to ensure encapsulation, but why can't I just call a method?

  Am I still add references to objects when you drag the axis class?

  Or is what adds the class itself?

  If this adds the class, how can I add a reference to an object of a certain class as a member of another class?

  I've attached a screenshot of the controller class.

  Thank you for your help.

  Hello

  The object Oriented Design is rater hard. Encapsulation banned, as you said, the data from your classes are defined outside their class.

  In your case it means that you have to create a data member access VI inside of the class of the Axes. These access screws (methods) allows you to set the values for these axes of type two objects inside of the controller of the class. Make sure that these two classes are in the less community.

  You can refer to a class using reference data value, Yes, BUT in this data type to the reference class is included. At the time, it seemed more convenient: LabVIEW programming job: The decisions behind the Design http://www.ni.com/white-paper/3574/en/

  Self an example here:

  Examples for the new reference value of data with the Forums of Discussion LVOOP https://forums.ni.com/t5/LabVIEW/Examples-for-New-Data-Value-Reference-with-LVOOP/td-p/1317493

  If you want to use data heavily references, I would recommend the GOOP package, which has different design questions build in singleton as etc. (which are not possible by default in LabVIEW)

• Access displays the objects within a class defined in a swc file?

  Is it possible to access display objects within a class defined in a swc file?

  To reproduce the problem:

  Step 1. I've set up a very simple FLA with an object defined in the library with the AssetView class:

  package

  {

  import flash.display.MovieClip;

  SerializableAttribute public class AssetView view extends

  {

  public var loader: MovieClip;

  public void AssetView()

  {

  Super();

  trace ("here it is:", charger);

  }

  }

  }

  In this object is a MovieClip with instance name loader. If the object is on the scene when the file is exported, you will see the trace:

  It's here: [object MovieClip]

  Step 2. I used Flash for publishing a swc, called "loader.swc".

  Step 3. I created a new actionscript project in Flash Builder and added "loader.swc" on the way to build ActionScript, the library, with the Type of link: merged into the code.

  Step 4. I instantiated "AssetView":

  var assetView:AssetView = new AssetView();

  I saw the trace:

  It's here: null

  --------

  I tried to delete the project actionscript AssetView class where it became priority during class with the CFC, but I still see no sign on the MovieClip.

  So, my question is, display objects are not accessible in the swc?

  + 1 for siniouse. The class definition does not contain the charger of the instance, but the symbol in the library only. If you need to

  var view: AssetView new MyLibrarySymbolLinkageName() as AssetView;

  What he says is quite likely to happen to you, but I thought I would add my 2 cents in the matter contributed to the clarification.

• Method calls on the timeline (scope?)

  Hello
  
  I use flash 8/2.
  
  I am trying to call methods on the timeline of a class and sometimes it works, and sometimes it isn't.
  
  A simplified example:
  In my fla I have 2 layers, one called "script" and the other called 'commScript '. In the layer "script" to the framework ' don't (say 5) and chassis only '5', I have:
  
  var applesFunction:Function = function (): Void {}
  trace ("apples called.");
  }
  
  In the layer "commscript", in the first keyframe is empty (and this keyframe extends through the timeline), I have:
  
  var grapesFunction:Function = function (): Void {}
  trace ("grapes called.");
  }
  
  In a method in a class (let's call it the "fruitMixer"), I will:
  
  public function test (): Void {}
  _root.applesFunction ();
  _root.grapesFunction ();
  }
  
  This object is also created in part 1, in the upper layer (which would be "script", "commScript" is on the layer below). When I run and call test() in the fruitMixer object, I get the result:
  
  'apples called.'
  
  Pushing further, I find actually, he can't see even the other method, a "trace (_root.grapesFunction); in the test() presents itself as "not defined".
  
  However, when I Exchange my order of the layer, all of a sudden, I get:
  
  'apples called.'
  "grape called."
  
  Even if it works, it seems fairly random. My question is: why is - this work? How is flash really handles this sort of thing? The order of the layers really matter, or was it some sort of strange chance / "magic"?

  HM, I guess for now, given that your conclusion is similar to mine, (and again, I have to find something in the fight it) I'm going to assume that this is how flash treats script on executives. If someone else wants to fix/add on, they are welcome to it.

  Thanks, GWD.

• Passing parameters to a method call in the workflow

  Hello

  I have a jsff page with a table it contains. To fill the table I used the default activity in the workflow.

  Table is is filled with data. When clicked on a line other jsff should get called.

  For this, we have written action method in the backup of the homepage bean.

  public String homeNavigation() {}

  Return "navigateToJobDetails";

  }

  and in the workflow if "navigateToJobDetails" is returned, we called breeding "getJobDetails" for complete details on employment and the method of flow control is given to the jobdetails.jsff page.

  This stream works very well, but we need to send parameters to the getJobDetails method. How this can be done.

  Help, please.

• How to pass attribute values after ExecuteWithParam to the method call

  Hello
  
  I use Jdev 11.1.1.6.
  
  My use case, is that I have mainPage BTF which has ExecuteWithParam as the default activity. It filters the VO using params. I have a requirement to store some of the attributes of current line to pageFlowScope which must be sent to several taskflows child.
  I present a method call after the ExecuteWithParam event and before the page is rendered but do not know how should I pass the current line (or something) in this method call to store values on pageFlowScope.
  
  What should I switch to this bean managed to store values on pageFlowScope? Is there an alternative?
  
  Thank you
  JAI

  I see two possible ways to get to the attributes. First of all, you can get the iterator current rank and get attributes here. Secondly, add you links attribute in the file pageDef methods for all attributes that you are interested in. Then you access it by using the attribute binding. I never tested the 2nd method, but I guess that the framework will fill the attribute links, as it does in a normal page.

  Sorry, can't give you enjoy this code adds that I'm not in front of a PC.

• To access a page method call parameters jsf page fields

  I have a workflow with a single method, call the execution after a point of view (jsf page).
  
  The view is a jsf page that allows to edit several fields to then filter a view object. This inputtext fields - components in general-have no connection.
  
  The next step in the workflow is executing a method call that takes these parameters - values entered previously in the jsf page - and to run a vo.setwhere and then a vo.exeuteQuery methods but I need the input provided in the previous page. I don't know what is the best method to get access in the ADF.
  
  I usually pass parameters to the method call in the page 'Change the binding of the Action', section 'settings' via EL expressions.

  You can have a support with scope pageFlow bean and bind the attribute to the property value as John mentioned. However, if you do not want to generate a bean, you can simple binding to a pageflow scope variable (might be created automatically).

  Something like

  value="#{pageFlowScope.someVariable}"
  

  and then for the methodCall activity, set the value of the parameter to the same as above EL.

• ERROR, called from the thread NON-INTERFACE QThread

  I am trying to load an image using QtConcurrent:map at the same time and I received this error.

  WARNING: ApplicationPrivate::context: ERROR called NON-INTERFACE QThread thread (0xf9ff68, name = "thread (pooled)" ")
  Fatal: ApplicationPrivate::context: method called from the UI thread

  I simplified the code as follows:

  imagescaler::queuescaling{
  ..    mimageScaling = new QFutureWatcher(this);
  mimageScaling->setFuture(QtConcurrent::mapped(mImageList, scaledImage));
  ..
  }
  
  Image scaledImage(QString file_name) {
     QImage qImage;
     bb::ImageData imageData(bb::PixelFormat::RGBA_Premultiplied, qImage.width(),
    qImage.height());  // causes error
    return imageData;
  }
  

  Anyone know what the problem is or how to work around?

  Thanks for point out the bb:ImageData.  Never noticed the incompatibility.  Image converts ImageData to initialization, so it does not create an error.  However, if I return an ImageData rather than the Image it does not crash.  I then simply convert ImageData of Image in the UI thread and it works very well.

  I'm curious to know why I can return a blank image and I can return an imageData, but I can't go back an Image that's been converted from ImageData.  Do not understand what can or cannot be done outside the UI thread.

• Returns the name of the object in a table

  Hello

  I received the canvas of the objects stored in a table. Each painting has its name property.

  Is it possible to return a specific name?

  Actually I need an index number of this table, where I spend a name property of the object within this table (the name is taken from the event). Something like this:

  x = array.indexOf (canvasName = event.currentTarget.name)

  Why can't you just to target the instance?  It's enough to tell the difference between different objects.

  x = array.indexOf (event.currentTarget);

• call shared the actor object function

  I run a large application using the Framework of the actor on the cRIO-9068.  LabVIEW 2013 SP1f2.

  One of my players must call a function from a .so shared object file that I created.  I also created a vi wrapper that contains the node of the library call.  The vi wrapper is not part of a library or a category.

  When I add the wrapper vi to one of the methods of the actor's and deploy the application; I get an error for the B indicating actor Core.vi actor charged with errors on the target and has been closed.  Here's where it gets interesting.

  If I remove B actor of the project, the error becomes actor C.

  If I remove the wrapper vi of the actor, the error disappears and my application runs as expected.

  If I have only the wrapper that VI on the target, the shared object function runs as expected without error.

  I'm out of ideas.  I will try to reproduce this problem on a small scale, but any help will be appreciated.

  Thanks in advance,

  Kevin

  Looks like I solved the problem by moving the .so to/usr/lib and by running chmod 0755 /usr/lib/libfoo.so

  would have been easier to repair if assigned deployment error to the actor actually using the library
