non-null validation method

• Non-Null Validation step does not work with the hidden field?

  Hello
  
  I have a field that is a selection list.
  
  I have another field, which is also a selection list, but which is masked by the dynamic loading of the page Action (if the value of the first field is 'False').
  
  If the value of the 1st select list is 'True', the 2nd selection list appears and the user must select a value.
  
  I have created a "Item Not Null" Validation, because I need to force the users to select the value in the 2nd, select list.
  
  However, the Validation does not work! I guess it's because the 2nd selection list is hidden / display by dynamic action!
  
  The 2nd selection list is null to display the value 'NULL '.
  
  How can I solve it please?

  It has nothing to do with the dynamic Action.

  Try to delete "NULL" in the value of the Null display field. Just leave it blank.
  In this case, "specified element is NOT NULL" must be selected in the Validation.

• Column manual non-null validation form

  Hi all

  I don't get the actual result with the code to validate the columns not null manual tabular form before submitting below. It retrieves the first row column only. I want to validate the columns in all rows.

  Can anyone please help and explain?

  begin
  for i in 1..apex_application.g_f03.count
  loop
  for j in 1..apex_application.g_f03.count
  loop
  if apex_application.g_f03(j) is null or i!=j
  then
  return 'Please Select a value';
  else
  return null;
  end if;
  end loop;
  end loop;
  end;
  

  Thank you

  Well go you twice the same table that seems weird.

  Then using return in the if statement you finish the operation of the service.

  If you want to collect all the lines for which the element is empty, see you the lines or the error message in a variable. And return the message only when all rows are processed.

  Something like

  declare
    v_message varchar2(2000);
  begin
    for j in 1..apex_application.g_f03.count
    loop
      if apex_application.g_f03(j) is null
      then
       v_message :=v_message||' Please select a value in row '||j ;
      end if;
    end loop;
    return v_message;
  end;

• validation working is not to count the non-null fields

  I have six fields on the screen, I want to check that at least 3 of them are filled (3)...
  I created a validation as follows to count the non-null fields... but it's not working...
  Please help solve this problem or recommend a better way to do this...
  
  
  declare
  number of question_count;
  Start
  question_count: = 0;
  If: p1_t_question_1 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_2 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_3 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_4 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_6 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  If: p1_t_question_6 is null then
  null;
  on the other
  question_count: =: question_count + 1;
  end if;
  
  If: question_count > 2 then return false;
  otherwise returns true;
  end if;
  end;

  I'll take a look a bit.
  In the meantime, check if the code as

  If the trim (both '%' from: p1_question_with_nul') = 'null '.

  help

  Ok. Take a look now. I used the function TRIM as shown above and also changed the comparison for questions 3 text based on ' if: p1_question_with_text is null'

  Seems to work now

  As I said, the PHP is not the value you are trying to assign to the text property of the textfield status_txt.  If you try to assign an undefined value.  Somewhere in your PHP, you do an echo of this value...

  echo "return_msg is whatever the message ';.

• Error #2007: HitTestObject parameter must be non-null error comes if I'm going to another frame without success

  Error #2007: HitTestObject parameter must be non-null

  at flash.display::DisplayObject/_hitTest()

  at flash.display::DisplayObject/hitTestObject()

  but my hitTestObject works well in the frame 4 displays error when I goto another frame without hitting the object

  If I touched the subject, then I goto frame 1 this error does not appear. This means that the code made mandatory hit error otherwise. How to get rid of this

  var live: myscrew = new myscrew();

  addEventListener (Event.ENTER_FRAME, checkCollision);

  function checkCollision(event:Event) {}

  star test against crescent

  If (keys.hitTestObject (chest)) {}

  Screw.x = 100;

  Screw.y = 100;

  addChild (screw);

  removeChild (chest);

  }

  }

  This code used to goto frame 1.

  arrowtwo.addEventListener (MouseEvent.CLICK, fl_MouseClickHandler_two222);

  function fl_MouseClickHandler_two222(event:MouseEvent):void

  {

  gotoAndStop (1);

  }

  Remove the event listener before you change settings.

  removeEventListener (Event.ENTER_FRAME, checkCollision);

• History of backfilling with non-null values

  Hi gurus,
  
  in Oracle 11 g, which would be the best way to update a null with the next available non-null value?
  
  For example: in the code below, I need to update the null in 20130201 record (key = 1) (key date) with a value of 100 available at the next available date IE 20130203.
  Same key = 3 value will be updated with key = 4 value i.e. 200.
  

  1,ABCD, 20130201, NULL
  2,ABCD,20130203, 100

  Hello

  Im doing some google ads on Flash CC but noted that google does not a flash drive which is above FP 10.1 so I saved to my Flash 5.5 and the encountered error tis swf files

  TypeError: Error #2007: url parameter must be non-null.

  I work in AS 3 CS 5.5 Mac and export to swf files in FP 9. I'm new on this point and im wondering if anyone can help me?

  Here is my code:

  

  Thanks in advance!

  You shouldn't nest a function inside an event listener, let it stand on its own.  In addition, you should try to leave the variable stand alone to assign so that there is a better chance, she is ready when it is called. (these imports are not necessary if coded in the timeline)

  var url: String = root.loaderInfo, parameters.clickTAG as String

  clicktag.addEventListener (MouseEvent.CLICK, processCT);

  This looks to another case of code not be placed where it should be.

  If this code is not in a function, then it executes immediately when the program starts.  At this point, snd is not defined, no said.  You do not create the instance until the line... snd = new Sound();   that, I believe, you have now moved inside a function.

  You might have to go through all the code to see what parts you always floating around this need of houses inside functions.

• TypeError: Error #2007: child parameter must be non-null.

  Hello

  I'm new to actionscript 3.0, I have Adobe Flash Builder installed 4.7 and I create a project (file-> new-> ActionScript project) ActionScript named Test. As you know flash builder does not include default fl.controls package. I added this package to my project as a file path or CFC source so that I can use the default components (e.g. buttons, radio buttons, checkboxes) and I'm writing the following code.

  package

  import flash.display.Sprite;

  Import fl.controls.Button;

  [SWF (width = "640" height = "480", frameRate = "60", backgroundColor = "#FFFFFF")]

  BTN = new Button();

  BTN.label = "CLICK ME!";

  BTN.x = 100;

  BTN.y = 100;

  addChild (btn);

  }

  }

  }

  I'm creating an instance of fl.controls.Button in the Test class and try to add it on stage. When I run the project, it always gives me the following error from the red line "BOLD".

  at flash.display::DisplayObjectContainer/addChildAt()

  to fl.controls::BaseButton/drawBackground() [C:\Program Files (x 86) \Adobe\Adobe Flash CS5.5\Common\Configuration\Component Source\ActionScript 3.0\User Interface\fl\controls\BaseButton.as:615]

  Please help me get rid of this problem. Thanks in advance.

  Thank you

  If you think that the bold line is the cause of the error due to the error saying "addChildAt" is involved, this isn't the same command.

  The error looks more like she points to something in the Button class and there is a problem.

  Normally when you work in Flash, with the class of the component is not enough for a file to execute without werror.  You will also need to drag a button in the library so that the 'physical' entity is available in the file when you try to create a new instance... components are, after all, not created from code only.  They are objects that are made using pieces of graphics and textfields and buttons and all that was used to create them by hand.

  In short, I think that you are away from the Button object in the library and when the class file tries to run it does not find a piece of the puzzle that is coded.

• Child parameter must be non-null. Error #2007

  Hello world!

  I'm about to finish my game (A matching game cards) and I encountered a problem.

  The piece of code tha giving me the problem is:

  compare two cards
  If (firstCard.cardface == secondCard.cardface) {}
  var beginTime:int = getTimer();
  addEventListener (Event.ENTER_FRAME, removeMatch);
  function removeMatch(event:Event) {}
  milliseconds spent
  var timePassed:int = getTimer () - beginTime;
  calculate seconds
  var seconds: int = Math.floor (timePassed/1000);
  If (seconds == 1) {}
  remove a match
  removeChild (firstCard);
  removeChild (secondCard);
  Reset selection
  firstCard = null;
  secondCard = null;
  }
  }
  Add points
  gameScore += pointsForMatch;
  showGameScore();
  playSound (theMatchSound);
  cardsLeft-= 2; 2 cards less

  TypeError: Error #2007: Parameter child must be non-null.

      at 
  Function/EasyDifficulty/clickCard/removeMatch()[C:\Users\Adi\Desktop\Playbook\Playbook
   Match Game\Project\EasyDifficulty.as:132]

  Above is the output error I get when clicking on two cards that are the same.

  What is the problem here... I can't fix perhaps because I worked for hours.

  Thanks in advance.

  The problem is probably due to you using an enterframe event continually calling this function.  You must remove this enterframe listener as soon as it has achieved its objectives, or else he will always try to remove objects that they have already been removed.

  You shouldn't bury this function inside the conditional.

  If the goal of all that is simply adds a slight delay before removing objects, you should consider using setTimeout or Timer class instead of using an enterframe scenario.

• TypeError: Error #2007: parameter listener must be non-null.

  Here is my code:

  function() {return A.apply (null, [this] .concat ($A (arguments)))}
  
  

  Click on the Section
  var nextSection;
  sectionName var;

  btnHome.addEventListener (MouseEvent.CLICK, fn_NextSection ("home"));
  btnAbout.addEventListener (MouseEvent.CLICK, fn_NextSection ("about"));
  btnProjects.addEventListener (MouseEvent.CLICK, fn_NextSection ("projects"));
  btnContact.addEventListener (MouseEvent.CLICK, fn_NextSection ("contact"));
  function fn_NextSection(sectionName:String) {}
  nextSection = sectionName;
  Play();
  }

  This is the error:

  function() {return A.apply (null, [this] .concat ($A (arguments)))}
  
  TypeError: Error #2007: parameter listener must be non-null.
  at flash.events::EventDispatcher/addEventListener()
  at player_fla::MainTimeline/frame361()

  You will need to provide the name of the right function. Passing parameters are not allowed:

  btnHome.addEventListener (MouseEvent.CLICK, fn_NextSection);
  btnAbout.addEventListener (MouseEvent.CLICK, fn_NextSection);
  btnProjects.addEventListener (MouseEvent.CLICK, fn_NextSection);
  btnContact.addEventListener (MouseEvent.CLICK, fn_NextSection);

  And listeners accept a single parameter and dattype - event:

  function fn_NextSection(e:MouseEvent):void
