Assignment to a Variable a Null value

• resolveNode returns a null value when a variable is used.

  LiveCycle Designer ES2, latest version

  Hello

  The following Javascript code, in the click event of a button, returns a null value for the variable opaque. When I manually enter the expected value the script works perfectly.

  I tried various modifications of the resolveNode line such as var opaque = xfa.resolveNode (qPage); , but without success.

  Also studied all the documents reference Adobe that I could find on the scripts and resolveNode. Any suggestions?

  var qPage = (Cell12.rawValue + "AnchorField");
  App.Alert (qPage);
  Opaque var = xfa.resolveNode ("' $... qPage '");
  App.Alert (opaque);
  var nPage = xfa.layout.absPage (opaque);
  App.Alert (nPage);
  xfa.host.currentPage = nPage;

  Thank you

  Ron

  I tried your sample and it seems to work very well... but I'm not sure 100% that you are trying to do... .going to your initial question on the passage of a variable in the resolveNode resolveNode expects a string, so you must use the following syntax to create the string:

  xfa.resolveNode ("$.." + qPage)

  Note that the variable is outside the quotes as such the string $... is added to the content of qPage. This wil work if qPage is a string as well.

  In your example you have defined qPage as an XFA object so that the syntax above will not work. If you intend to use the same way, you would use qPage.name so that the name of the field will be returned (this is a string) and it will be added to your expression of $ to make the $... ProductAnchorField

  Thus, the expression would be:

  xfa.resolveNode ("$.." + qPage.name)

  Make sense?

• MS SQL 2005: Assigning null value

  For some reason any I have been finding it impossible to assign the value of '0' to the count() null result. It was easy to identify NULL values, but the assignment zero fails permanently.

  I have it!

  The subquery is evaluated to NULL, so it just hit me to ISNULL the subquery set! Lol, wow. 4 days for that point and its that simple.

  Thanks for the help Phil.

• apex5, a null value to the title of the tree made the developer toolbar disappear

  Hello

  With for example the query tree:

  select case when connect_by_isleaf = 1 then 0
              when level = 1             then 1
              else                           -1
         end as status, 
         level, 
         (CASE WHEN "ENAME" = 'KING' THEN null ELSE "ENAME" END) as title, -- null value is evil
         null as icon, 
         "EMPNO" as value, 
         null as tooltip, 
         null as link 
  from "#OWNER#"."EMP"
  start with "MGR" is null
  connect by prior "EMPNO" = "MGR"
  order siblings by "ENAME"
  

  The developer toolbar disappears when there is a value zero in the title. It's very very difficult to detect the problem.

  Rgrds Paavo

  Hi Paavo,

  Can I ask what you are trying to achieve by one of the labels by assigning null value?

  Null or an empty string are not useful as a tree node labels. Yet we could be as a minor bug that the area of the tree should be more robust in the JavaScript that it generates.

  Detect the problem (disappears from the dev toolbar) is not different from almost all JavaScript errors. Whenever any client-side behavior seems to not work, for example, no dev toolbar or a tree node does not expand, or a menu is not falling down, or something is not show or hide it should etc, the first thing to check is the browser console log. In this case, it shows the error ' SyntaxError: lack the name of the variable.

  Kind regards

• Check if the variable is null / not affected

  Hello

  I've been unable to find explicitly for an answer to the question how to check if a variable is null or Unassigned or not defined. As some analog to java fi (var == null).

  The variable in question is of type xsd: Integer. I use the assign activity where I use oraext:lookup - table. If the (integer) value is not found in the database, then the variable remains unaffected. However, I am of ideas of how to do to check if it's still not affected or not

  Thank you!

  To check if the value of a variable (in bpel) is null or empty, I think you can use this expression - bpws:getVariableData('variable') = "(just two quotes together), in a condition of switch-case / if-else.

• return type is not specified... return type so how you return a null value

  My problem seems to be when no results are returned, I would return the same type of object, but as a null value, or almost, I think that's what I would do. If someone could please throw some light on how I should return a null object I would be very grateful.

  I should note I've already tried to return entityNew ("someObj") and which resulted also in failure.

  <!--get some object-->

  < cffunction name = "getSomeObject" returntype = "someObj" = "remote access" >

  < name cfargument = "client_key" required = "true" type = "string" >

  < name cfargument = "customer_id" type = "string" required = "true" / >

  < cfscript >

  value = [];

  value = entityload ("une_table", {client_key = "#client_key #", customer_id = "#customer_id #"});

  If (ArrayLen (value) == 1)

  {

  Returns the value [1];

  }

  return;

  < / cfscript >

  < / cffunction >

  < / cfproperty >

  Thank you in advance!

  You do something like ?

  If so, then again CF has no concept of null so you cannot assign to a variable CF.  If you return null, first change your attribute of the returntype to "any" and return it directly,

• NPE for rows with null values in the table of the adv

  I created the table adv, 2 columns, equipped with two text fields. Initially the col2 is empty,
  say that the structure is as follows:

                col1          col2
  Hdr         Question    Answer
  row1       abc           zxc
  row2       pdd           null (user doesnt enter anything)
  row3       zxc            lkj
  
  APPLYBUTTON

  When the user clicks on apply button I want to update these values in the table.
  
  I don't know how to do that, but that's what I'm trying to do. Please guide me the right way if its wrong.
  
  in LICS, I took the APPLYBUTTON action, got all lines of the object corresponding to the view, consulted with everyrow and I'm checking if there are values in the fields in the table, if the value zero, are simply print null. (we would not update on this line). . I could get o the part update, due to null pointer exception
  I get on the row line null pointer exception [1].getAttribute("Answer") for row2, it prints the value of row1 however.
  
  Here is the code I wrote:
  Set of rows from the rowset = (RowSet) vo.getRowSet ();
  Rank rank [] = vo.getAllRowsInRange ();
  System.out.println ("row.length" + row.length);
  for (int i = 0; i < row.length; i ++) {}
  String question = row.getAttribute("Question").toString ();
  String response = row [i].getAttribute("Answer").toString ();
  If (question! = null & &!("".)) Equals (question. Trim()))
  {
  System.out.println ("Question line" + i + "-" + question);
  }
  on the other
  {
  System.out.println ("Question line" + i + "is null");
  }
  
  If (response! = null & &!("".)) Equals (Answer.Trim ()))
  {
  System.out.println ("Response line" + i + "-" + response);
  }
  on the other
  {
  System.out.println ("Response line" + i + "is null");
  }
  
  Why the NPE survey code, I'm checking for null value and you want to print the value null in the logfile... I can not to getAttribute() on the null field, why can not just give me null in the variable I'm assigning to?
  
  You can guide me what approach to take, if it is not correct.
  I must examine DataDictionary and collect data there?

• How to deal with NULL values in regexp_substr?

  DECLARE
     TYPE t_rec IS TABLE OF VARCHAR2(200);
  
  /* case 1 */
     l_input    varchar2(100) := '28/09/2009 00:00:00|AFRISB|FC|773|7|17|512|76|60|U|';

  --   l_input    VARCHAR2(100) := '06/10/2009 00:00:00|PDIERR|PS|999|0|1|0|0||U|';

     l_rec      t_rec := t_rec();
  BEGIN
     l_bars     := regexp_count(l_input, '\|', 1, 'i');
     l_fields   := l_bars + 1;
  
     FOR fld IN 1 .. l_fields
     LOOP
        l_rec.EXTEND();
  
        l_rec(fld)   := REGEXP_SUBSTR(l_input, '[^|]+', 1, fld);
        dbms_output.put_line('Fld ' || fld || ': ' || l_rec(fld));
     END LOOP;
  END;
  

  The above code is that I break a string of pipe delimited into individual elements.

  Looking at the case 1 in the code, the output displays each field correctly. However in case 2, the 9th field is null (nothing between the two tubes) so the regexp_substr 19 online is assigning the 'U' in the box 10 as a field 9.

  What should I do to get the line 19 to correctly assign a NULL value to field 9?

  Hello

  If you want to use regexes, so instead of

  REGEXP_SUBSTR (l_input, "[^ |]") +', 1, fld);

  use

  REGEXP_SUBSTR (l_input

  , '([^|] *)(\|| $)'

  -P

  fld

  NULL

  -P

  );

  . The 6th argument to REGEXP_SUBSTR is a new feature of Oracle 11.1.  It's kind of a back reference. Normally, REGEXP_SUBSTR returns the substring that matches the pattern in the 2nd argument.  If the 6th argument is 1, however, REGEXP_SUBSTR returns only the part of the pattern between the 1st on the left '(' et sa correspondance)."

• CERTAIN behaviors, NULL values

  I am a little confused about the following situation:

  I have a PL/SQL code with a block similar to this:

  BEGIN
  SELECT MAX (col1)
  IN myVar
  FROM MyTable
  WHERE col1 < (SELECT MAX (col1) FROM MaTable;
  
  EXCEPTION
  WHEN NO_DATA_FOUND THEN
  myVar: < something > =;
  WHEN OTHERS RAISE.
  END;
  

  The behavior I expect from this is to assign a value to myVar, which is the next most great. value to the record value of col1.  If there is no record in myTable the NO_DATA_FOUND exception is thrown and myVar is filled with predetermined values.  Everything works fine execpt...

  When there is only one record stored in myTable, there is no exception raised and myVar is assigned to NULL.  I think that since there is only one line in the table there is no trace of return that meets the SELECTION criteria and therefore the NO_DATA_FOUND exception which is not the case here would be raised but myVar is assigned NULL and the program continues to flow from there.

  What is the problem with my way of thinking that the exception must be raised when there is a single record in myTable?

  Thank you.

  Documentation:

  A SELECT INTO statement returns no rows, or your program refers to an element deleted in a nested table or a component not initialized in an index - by table. Aggregate SQL such as AVG and SUM always functions return a value or a null value. As a result, a SELECT INTO statement that calls an aggregate function ever triggers NO_DATA_FOUND.

  That would be your MAX.

• Properties: Treatment of NULL values

  I wanted to ask you how you deal with NULL values, on the properties of JavaFX.

  Properties of the wrapper for the primitive data types like SimpleIntegerProperty or SimpleBooleanProperty Don t accepts NULL values.

  Example:

  1. IntegerProperty integerProperty = new SimpleIntegerProperty() )
  2. integerProperty. setValue (null) ;
  3. System. out. println () integerProperty. getValue ());

  Output is 0 (default value for "int").

  I think the primitive property wrappers (IntegerProperty, BooleanProperty and friends) as of the wrappers for primitive types. Probably they shouldn't really inherit WritableValue as which allows the call to setValue with a type reference, but I think that indigestion API would be worse than the implementation of setValue with a slightly incorrect signature. I would just avoid defining a wrapper of primitive type to null property: If you want to restrict yourself using set (.) instead of setValue (...) you are forced to spend in the primitive type: either you cannot pass null.

  If you want an integer property where null values are handled in an intuitive manner, use ObjectProperty .

  The test below shows that call setValue (null) on IntegerProperty assigns the default value. (Although I don't see the behavior documented anywhere).

  import javafx.beans.property.IntegerProperty;
  import javafx.beans.property.ObjectProperty;
  import javafx.beans.property.SimpleIntegerProperty;
  import javafx.beans.property.SimpleObjectProperty;
  import javafx.beans.value.ChangeListener;
  import javafx.beans.value.ObservableValue;
  
  public class PrimitivePropertyWrapperTest {
  
      public static void main(String[] args) {
          IntegerProperty integerProp = new SimpleIntegerProperty();
          integerProp.addListener(new ChangeListener() {
  
              @Override
              public void changed(ObservableValue observable,
                      Number oldValue, Number newValue) {
                  System.out.println("integerProperty changed value from "+oldValue+" to "+newValue);
              }
          });
  
          ObjectProperty objectProp = new SimpleObjectProperty<>();
          objectProp.addListener(new ChangeListener() {
  
              @Override
              public void changed(ObservableValue observable,
                      Integer oldValue, Integer newValue) {
                  System.out.println("objectProperty changed value from "+oldValue+" to "+newValue);
              }
          });
  
          integerProp.setValue(null);
          integerProp.setValue(1);
          System.out.println("setting integerProp back to null:");
          integerProp.setValue(null);
          System.out.println("setting integerProp to 0:");
          integerProp.setValue(0);
          integerProp.setValue(null);
  
          objectProp.setValue(null);
          objectProp.setValue(1);
          objectProp.setValue(null);
          objectProp.setValue(0);

• Out of Java simple assignment to a Variable

  Is it possible to have a variable in a package that is assigned a value returned by a call to the Java method so that I can use this variable across all interfaces in the package. Here's what I'd like to see (pseudocode)
  
  -Beginning of package execution
  -Java.util.UUID.randomUUID (m:System.NET.SocketAddress.ToString assing to variable 'UUID ()) '.
  -Run interface 1
  -#UUID in a field map
  -Run interface 2
  -card of the same value in a field #UUID
  -Start to end run
  
  Thank you

  Yes it is possible. You must create an odi for this procedure. Inside of the odi procedure take technology java beanshell and write code like below.
  <>
  Java codes hoes here
  String java_v = "Chantal".
  Java codes hoes here
  @>

  Now drag this procedure in the odi package. Then, drag another odi odi package variable. Set mode assign the java variable to the odivariable as follows.
  <@=java_v@>

  Its done. Are you reeady to use variable odi everywhere wherever you need in a single package.

• Assignment of global variables

  I apologize if this is a fundamental and simple question, but I was pulling my hair out for the last week trying to get this working and Google becomes sick and tired of my questions to get answers.  This should not be so difficult, but I'm not a designer, not a programmer, I'm just a tech trying to make my life easier, then Yes, I brought it on me.

  I have converted an InDesign form that has a bunch of boxes in a document of LiveCycle.  I want the boxes when they are verified to assign a value to the variable assocated.  In the properties of the form, I've set up global variables and assign the value to '0 '.

  The box I put the method/property to change to have the following code:

  If (topmostSubform.Page1.Back_Cover.rawValue == 1)

  BC.value = 6300;

  on the other

  BC.value = 0;

  I have a textbox that I am taking all these values and based on what is checked and this is not it must calculate the total for this field.  Here is the code I have for the calculation of the value of text using the method/property to calculate:

  premium.rawValue = BC.value + IFC.value + IBC.value;  There are three check boxes associated with this value

  However, no matter what I do not values seem to are they assigned to the variable of BC.

  Can someone tell me please in common sense as to why it doesn't work?

  Thank you very much.

  Tom

  Hello

  I think Steve is right, you want to avoid using global (or form) variables in this case, particularly in the case of calculating as any change that value will not cause a recalculation.  I have also try and keep all the logic of calculation in one place.  So, in the case of calculating the premium field, I would put the following JavaScript code;

  this.rawValue = (Back_Cover.rawValue = 'On')? 6300: 0;

  this.rawValue += (Inside_Front_Cover.rawValue = 'On')? 5775: 0;

  this.rawValue += (Inside_Back_Cover.rawValue = 'On')? 5350: 0;

  Note that the power of your checkboxes values are the strings 'On' and 'Off '.
