  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

  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;

• Dynamic Actions disable button based on the text field

  Hello

  Sorry if this has already been asked but I checked and could not find a job.

  «I'm trying to disable / enable a button "view" among the elements of this region from if a text field has a value or.»  I created a dynamic action for this but its not working only partially.  I can get the button to be disabled or enabled when I leave the text field, but what I'm trying to do is to get the State of button to change as soon as I start to type in the text field or return to people with disabilities if the text is deleted.

  I don't know that I'm missing something simple and help you can give is greatly appreciated.

  I use APEX 4.1 and that's how I got the dynamic action implementation, I tried different but no event types to give them action I want.

  I also install an example (details below)

  Event - change

  Selection type - point

  Article (s) - P1_TEXT

  Condition - is null

  Real Action

  Action - disable

  Fires when the result of the event is - real

  Fire on the loading of the Page - Y

  Items affected - button

  Article (s) - P1_BUTTON

  Action of false

  Action - Enable

  Fires when the result of the event is - fake

  Fire on the loading of the Page - Y

  Items affected - button

  Article (s) - P1_BUTTON

  workspace - show_issue

  user_name - show_issue

  password - show_issue

  app_id - 61707

  It works as expected if you change the event of 'Change' for 'key version?

• Can a single button cause multiple targets, based on the value of the point?

  I have a button on a form and based on the value of an element, when clicked, pages must be accessible. Is this possible to do? If so, any ideas are greatly appreciated.
  
  Request Express 3.1.2.00.02

  It's pretty simple to do using conditional branches. Create a branch to the place of the appropriate branch (for example on submit: after treatment...) for each target page and series PL/SQL Expression condition for each branch:

      :request = ''
  and : = 
  

  its replacement by < button_name >, < nom_element > and < item_value > with the values appropriate to your application (and change the '=' in the expression of the agenda if some other condition is used). The integrated attribute REQUEST contains the name of the button that submits the page.

• How to enable and disable a button depending on the value of a field

  Hello experts,
  
  I enable and disable a button depending on the value of a field.
  
  I did the following:
  
  in a trigger of on_new_form_instrance I put the following

  begin
       
  go_block('OE_HEADER');
  execute_query;
  IF :oe_header.status = 'BOOKED' THEN        
        SET_ITEM_PROPERTY('CONTROL.ACTION',ENABLED,PROPERTY_FALSE);
  else
       SET_ITEM_PROPERTY('CONTROL.ACTION',ENABLED,PROPERTY_TRUE);
  end if;
  
  
  end;

  the problem is that it works but does not change when my header_status value is changed.

  You have to put the same code in when-validate-item trigger of: oe_header.status...

  and I think that this code should be trigger after query

  IF: oe_header.status = 'RESERVED' THEN
  SET_ITEM_PROPERTY('CONTROL.) ACTION', ENABLED, PROPERTY_FALSE);
  on the other
  SET_ITEM_PROPERTY('CONTROL.) ACTION', ENABLED, PROPERTY_TRUE);
  end if;

• How to create table selectable line or not based on the value of the line

  Hello.
  
  JDeveloper 11.1.1.2
  
  Is it possible to make a selectable table row or not based on a value in the line.
  
  That is to say. lets say that the row contains a Boolean LOCKED = TRUE.
  This line should not be selectable.
  
  A line whose value LOCKED = FALSE should be selectable.
  
  / Erik

  Erik,

  No particular reason to disable a selection of lines for a particular line? If I'm an end user, I would be clicking on the same line of thought again and again my mouse does not ;) (call me dumb :)). How do you differentiate this line (using inlineStyle / styleClass) based on the value of line? In addition, you can disable the other buttons when a row with a particular value is selected (so that the user knows that the selected line is not treatable).

• Web page open based on the value of the text field

  I want to open a web page that is based on the value of a text field.  How to bind the value of a text field to a command which will open the web page?

  For example, the value of the text field is: 8 t - EXT

  and the web page I want to open when you press a button is: http://hqms/doc.asp?dn=8T-EXT

  As you can see that the 8 t - EXT is something that a person enters the form and is what is needed to open the web page.  The other text in the link of the webpage is always the same.

  Thank you

  Hello

  In the click event of the button, place the following JavaScript code:

  if (TextField1.rawValue !== null) {
       var vURL = "http://hqms/doc.asp?dn=" + TextField1.rawValue;
       app.launchURL(vURL, true);
  }
  else {
       app.alert("Dear user, please put a code in the text field. Thank you!");
  }
  

  You need to change the object references based on your shape.

• Display a series of images on the stage based on the value of a variable

  Hi all
  
  Here's another interesting problem! Well, I have an interactive retention test which is charge of an xml file based on the value of a variable scenario (for example, if script = Architecture, then load Q_set 1, if scenario = history then load something else). Now, I would like to extent this and display a series of images on my stage which will be valid only in the current scenario. Here is my code so far. I thought load a list of images on the beginning of the film (for example, Architecture_list, History_list) and then call them according to the value of the variable of scenario, but I would like to hear what you have to say. Any ideas?

  The answer is a series of managers: one called at the beginning of the movie to fill the lists of the appropriate folders (based on the value of the variable gimage) and the other called next and previous. Here they are in case yu need:

  ---------
  Global gFileList, gImagePath, gimages

  on buildList

  gFileList =]

  -defining the path to images:

  gImagePath = "@images /" & gimages & ' / ' "»

  Repeat with i = 1 to the maxinteger
  thisFile = getNthFileNameInFolder (gImagePath, i)
  If thisFile = EMPTY then exit
  If thisFile = the movie then the next repetition
  types of files = [".pct", ".jpg", ".bmp", ".gif"]
  howManyTypes = count (fileTypes)
  Repeat with thisType = 1 to howManyTypes
  extension = getAt (file types, if thisType)
  If thisFile contains extension then
  gFileList.append (thisFile)
  end if
  end repeat
  end repeat

  Member ("Display"). FileName = gImagePath & gFileList [1] - put the first image in the folder at the appropriate place

  Member ("Display"). Picture = .photo member ("display")

  buildList end

  --------------------
  Global gFileList, gFileIndex, gImagePath

  on nextFile

  gFileIndex = gFileIndex + 1

  If gFileIndex > count (gFileList) then

  whichFile = gFileList [1] - set the image = in the last loaded picture holder
  gFileIndex = 1 - the value of the index to the last trick question

  Member ("Display"). FileName = gImagePath & whichFile
  Member ("Display"). Picture = .photo member ("display")
  updateStage

  -go to the audio issues

  _movie. GB (31)

  on the other

  whichFile = gFileList.getAt (gFileIndex)

  Member ("Display"). FileName = gImagePath & whichFile

  Member ("Display"). Picture = .photo member ("display")

  updateStage
  end if

  end

  Global gFileList, gFileIndex, gImagePath
  -----------------------------------------------------------
  the backfile

  gFileIndex = gFileIndex - 1

  If gFileIndex = 1 then

  whichFile = gFileList [1]
  Member ("Display"). FileName = gImagePath & whichFile
  Member ("Display"). Picture = .photo member ("display")
  updateStage
  Sprite (17) TRUE = FALSE - disable the "back" button

  -gFileIndex = count (gFileList)
  end if

  If gFileIndex > 1 then

  whichFile = gFileList.getAt (gFileIndex)

  Member ("Display"). FileName = gImagePath & whichFile
  Member ("Display"). Picture = .photo member ("display")
  updateStage
  end if

• Element of change based on the value in LOV

  I'm trying to disable the item (text box), based on the value of the LOV. And it doesn't seem to work.

  Is it possible to see what is happening in the level of the events? The LOV is perhaps not "changing" ing?

  Patrick Wolf-Oracle responded to the question - get the firebug.

  Looking at the console I discovered that the returned of LOV value includes spaces. Resolved issues.

• Delete in the database based on the values of the multiple selection list

  Hello
  
  I have a selectlist in Apex and a function in the database to make a deletion based on the value selected in the selection list.
  

  FUNCTION delete_batch (v_batch VARCHAR2) RETURN VARCHAR2
  IS
  BEGIN
  IF v_batch like 'M%'
  THEN
     RETURN ('A monthrun cannot be deleted');
  ELSE
     DELETE FROM so_disco_pa
     WHERE  batch = v_batch
     ;
     DELETE FROM so_batch_pa
     WHERE  batch = v_batch
     ;
     COMMIT;
     RETURN ('Batch '||v_batch||' has been deleted');
  END IF;
  EXCEPTION
  WHEN OTHERS THEN
      RETURN ('Batch could not be deleted');
  END delete_batch;

  The package is called when the user clicks on the button Delete with the rest of the process:

  BEGIN
  DECLARE
  x   varchar2(100);
  BEGIN
  x := pa_control.delete_batch (:P3_BATCH);
  :F105_MESSAGE := x;
  END;
  END;

  Now, I want to change the selectlist for a multiple-selection list to make several batches can be deleted.
  
  How can I change my procedure and the procedure to remove lots based on the values selected?
  
  Thank you
  
  Diana

  dianap says:
  I got this far, but only the first batch selected in the list is being deleted. The other values of selected package are not removed.

  Help please.

  Move the RETURN statement out of your loop.

• Dynamic action based on the value in a table

  Greetings,
  
  I would like to use a dynamic action to disable a button depending on the value selected/entry in a field in tabular form. Thus, for example, if someone enters the value "LKSG", then a button is disabled (in this case, the 'Add Row' button).
  
  How I would do this using the tools of dynamic measurements? When I create a dynamic action, I see that my choice of Type 'selection' for dynamic action of shooting is point, area, button, object DOM, jQuery Selector. I don't know how to use a field in a presentation of tabular to firing. Or if it is possible.
  
  I use APEX version 4.1.1.00.23
  
  Thanks in advance!

  Tom - it's very useful! A few questions:

  -J' use a 'button of the model '. To use the static code for the button, I see that the model must include the #BUTTON_ID # in the model. I added the #BUTTON_ID # in the template like this:

  
  
  
  #LABEL#
  
  
  
  

  Where is the the BUTTON_ID should go, in the

  ?

  After adding this, it does not for a button of the model. But if I change the touch of a button HTML, your method works great!

  It is of course the difference between the two buttons: how they react and, above all, how they are marked upward. An HTML button is a real element, while the model one is obviously not. In addition, the HTML button can be disabled, while the model cannot.
  So if you want to continue to use the model button, do not use the "disable" action, but use the 'hide '. I would not advise to implement a disable - like behavior of the button model that involves even more javascript/jquery, I'd like to avoid if you're not comfortable or familiar with her.
  That said, I would say that for this case, adding the string #BUTTON_ID # in the array element itself will work great because this will cause this entire item is hidden. If you had only added to the anchor tag in the second cell, then you would get weird questions. You need to change the model, because your markup is not correct for the id of work: the substitution string will replace only the given ID and not add the actual attribute (id =""):

  -In addition, in your solution, you have real Action--> jQuery selector: #addRowButton. Is that correct, or should it be #addRowButton? # (# at the end)
  Yes, that's correct. ' # ' is for 'select by id' jQuery selector: http://api.jquery.com/id-selector/
  In addition, it is the selector jQuery for the item assigned to the real action, not to be confused with the trigger for dynamic action.
   
  		     
  How to render components based on the value selected in a list of values
   
  			 Hello
  I created a form of the ADF. I have a drop down that is a list of values. I want to toggle certain fields based on the values selected in the menu drop-down. Could you please let me know how to do it in the ADF?
  
  
  Kind regards
  Murielle			 
  Hello
  It should work. It is important to note that in case you use a component selectOneChoice for category then the value returned by #{bindings. Category.inputValue}
  is the index of the selected value in the list and not the value auto. To get the value, you must use ' #{bindings. " Category.attributeValue}"in the disabled state.
  If the problem is no display of code in your page to take a look.

  How to conditionally display images based on the values of the variables
   
  			 
  I am building a demonstration Captivate containing a slide branching that allows the user to choose which way they want to view; Once they are done, they come back on this slide branching, and I want a check mark to display the button/path that they have already completed.
  I'm new to the use of variables and actionscript in Captivate, so I went the the documentation and the creation of variable is clear, as well as the use of conditional constructions, but I didn't know the instructions of scripts that look like they will allow me to display an image from the library when she is called in the conditional.
  Is this possible? If so, a pointer to an appropriate documentation or sample code would be greatly appreciated.
  Thank you
  Josh
  			 
  Hello
  When you insert images of the box, you click the Options tab and give the image a name that you may recognize. Then clear the Visible check box. This allows to keep hidden until you want to show it.
  
  However, note that even if all the image names are listed in the dialog box advanced Actions as being available for show, you will only be able to show an image if you run the fast Action of the blade where the image exists. So you will likely build a means by which you are setting up a variable to indicate that a section has been visited. Then create an action that is performed on slide enter to show the images based on the values of the variables.
  See you soon... Rick
