• Call the method call activities before you navigate to the target jsf page

  Dear all,

  I use JDeveloper Studio Edition Version 12.1.3.0.0.

  Requirement:

  I have a stubborn taskflow. The stubborn workflow is without using page fragments.

  I have three pages: login.jsf, admin.jsf, user.jsf. I have a method call activity in the taskflow. The login.jsf is the default page. The page of login.jsf have an af:selectOneRadio with two af:selectItem: Admin and user. It also has an af:button. When the user select the af: af selectItem: selectOneRadio and click on the af: button, it should call the method call activity (doLogin) and based on logic it will redirect to the page admin.jsf or user.jsf page.

  Please find the taskflow below:

  

  How to achieve the solution to the prescription above.

  Thank you and best regards,

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

  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;

• 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.

  Hello

  It contains only the activity of the method, and if so, why is he launched with the help of a new transaction? Note that navigation always is an ID of the view and the workflow will not run if there is no view to navigate to. So either the calling flow calls this workflow and workflow returns immediately after execution of the activity of default method then it refers to a display of flow tasks calling or you add a view. Note that cookies are set on the response of a call and it is not issued before coming to a view. For this reason, using a method call activity could be a bad approach to try this so a phase listener is better suited

• 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.

• Passing parameters to the method call in expressions of value

  JDeveloper 11.1.2.1.0 does support the feature of passing parameters to method calls in expressions of value in JSF pages? AFAIK this is JSF 2 version it and it should support this feature. Unfortunately when I put in a JSF page the following tag
  < h:commandLink value = "#{row.employeeId}" action = "#{empBean.showDetails (row)}" / > "
  The page does not work. Any ideas on this point?

• class .as CFC method call

  so I got a .swc and I was informed that its got a method called doSomething();
  
  for one reason or another, I can't include the swf file in my fla. what I need to do, it's somehow include the swc in an AS3 class and then call the CFC method therefrom.
  
  so I got it here, in a directory called 'swc' sound called 'someSWC.swc' and I need import into someClass.as and call the doSomething() about it.
  
  and I have no idea how I would... anyone?

  Hi andrei1

  of course, Ive had to bash my head against this for a few days to find a solution. Yes I found out that if you can bust open a CFC as you suggest it you find an xml file that indexes the content of CFC and a swf file that contains the different methods/assets/graphics/etc. When you look in the tags in the XML indexical you can find references to AS3 objects like this:

• 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)
