• How to get the value of the element of choice of message in application of process?

  Hello
  
  In the method of application of the process of the page controller
  I need to get the value of the element of choice of message on the page and then pass the value to am method to call a vo query that requires message value as parameter choice
  I tried
  
  Weekend OAMessageChoiceBean = (OAMessageChoiceBean) webBean.findChildRecursive ("WkEndList");
  If (weekend! = null)
  System.out.println ("sag down:" + weekend.getValue (pageContext));
  
  am.invokeMethod ("initQuery", end of week);
  
  
  but I'm getting null for the value of the weekend, although the page is shows the values in the drop down.
  
  
  Help, please.

  Thank you Gyan,

  I mentioned to use PPR only when the call must be made immediately after the selection of the value.

  If you are looking for value without preconditions,
  GYAN suggested use String WkEndListValue = (String) pageContext.getParameter ("WkEndList");
  You should get the value.

  Thank you

• Delete empty item in, select one time choice

  Hello
  I use JDeveloper 11.1.1.4.
  I have a jspx page that has a select statement after choice as below.
  
  "< af:selectOneChoice label ="guru of the ADF"value =" #{testMB.selcOneValue} "required ="true">
  < f: selectItem itemLabel = "Option1" Valeurelement = "1" / >
  < f: selectItem itemLabel = "Option2" Valeurelement = "2" / >
  < f: selectItem itemLabel = 'Option3' Valeurelement = "3" / >
  < / af:selectOneChoice >
  
  But an empty value is always displayed in selection once.
  
  How to remove a value empty in the choice of selectone.
  
  Kind regards
  Praveen

  Hello

  I suppose you have no default value defined for the attribute (which is linked to the value property of your SOC) in your beans. In your testMB, set the value of the attribute to a default value selectOneValue and see if it solves your problem.

  private  selectOneValue=1;
  ....
  ....
  public  getSelectOneValue(){
  return this.selectOneValue;
  }
  
  public setSelectOneValue( value){
  this.selectOneValue=value;
  }

• Update a record of ORM, but with empty value

  Hi all, excuse my poor English and my level of coldfusion poor

  I have some problems to update the data with ORM objects.

  (1) I have an object of customer with a task property (many-to-one relationships)
  (2) I have a job object (a list of works)

  When I update a client with customerOBJ.setjob (jobOBJ); It is ok

  But when I can't seem to restore an empty value for the job.

  When I try this:

  customerOBJ.setJob (), I have an error because the settings is not a type of employment

  You have some information about this?

  Thanks in advance.

  Hi friend

  This allows to obtain a value zero: javacast("null",'"")

  That is why to delete the value:

  customerOBJ.setJob (javacast("null",""));

  That should make you well. If you use it in a few places, you can create yourself a function:

  Then use:

  customerOBJ.setJob (null);

• I know this has been asked before but I deleted 6 months value of files, can not use cancel.

  I know this has been asked before but I deleted 10 months value of files, cannot use cancel and have not saved (live & learn) someone posted do a restore from "Import and backup" my restore ad is only 2010-6-29 to 2010-6-22. Is this the way to go to recover as much as possible, or is there another solution?

  These dates are when a backup was performed automatically by Firefox, no dates when you saved bookmarks. Try to restore the backup of the day which you removed all bookmarks. It will restore the backup file-not only what you deleted, you will lose all the bookmarks you saved after the date of the file that restore you.

• How to read the size of the array, eliminating empty values

  I have an array of size 2 X 10. In the first column, the elements are 10 and in the second column, the elements are only 6. If I use the size of the array and the size of the second column of the index, the value given is 10 which is supposed to be 6. I noticed that it creates null or empty values in the column for the other four. How can I eliminate empty values, and only get the real sze of the column?

  The column in the index and use search 1 D table for an empty string.  The result should be the number of non-empty strings.  If the result is - 1, use the actual size of table.

  The user can omit one of the lines, not necessarily the last population. In fact, it can fail to complete the entire form.

  The best solution is to validate the data prior to the insertion of the database. For example, you can see empty lines as follows

• Value at the bean do not reset on the valuechange listener appeal.

  Hello
  
  I am new to this technology. I wrote a custom validator in my bean class to validate if the due date is greater than start date.
  
  < columns af:inputDate = "10" label = "EndDate" id = "endDate" clientComponent = "true".
  value autoSubmit = "#{viewScope.Bean1.EndDate}" = 'true' "
  Binding = "#{viewScope.Bean1.EndDate} '"
  immediate = "true".
  Validator = "#{viewScope.Bean1.validateStartandEndDate} '"
  valueChangeListener = "#{viewScope.Bean1.changeDateValuesOnSelection}" >
  
  Validation is performed when I click on the "submit" button. Problem is if the first time I choose the date to give EM i.e. end date of small to start the date of Validation takes place. Date values are defined in the bean. Now if I change the above date end date (and not only not to give the Error Message) start always get EM as the validator supports only the values of old bean. ValueChange listener not called in the bean method. Yet when EM comes where it shouldn't come.
  
  Please help on how to get the changed values in the date field.

• Delete all empty layers except one?

  Hello

  This script deletes all layers of empty/white. I need to delete all empty/white layers with the exception of the layer named "grid."

  I tried searching the forum for some clues, but I'm stumped. Any help would be greatly appreciated.

  I thank very you much.

  var myLayers = app.activeDocument.layers.everyItem () .getElements ();

  for (var i = myLayers.length - 1; i > = 0; i--) {}

  {if(myLayers[i].pageItems.Length==0)}

  myLayers [i] .remove ();

  continue;

  }

  }

  It works for me:

  Main();
  
  function Main() {
      var i,
      myLayers = app.activeDocument.layers.everyItem().getElements();
  
      for (var i = myLayers.length-1; i >=0; i--) {
          if(myLayers[i].pageItems.length == 0) {
              if (myLayers[i].name != "Grid") myLayers[i].remove();
          }

  I would be greatfull for any help

  I managed to solve the problem.

  Ultimately I don't check if the values were empty, as it worked fine without. However, the switch of the price did not work in combination with the rest of the query.

  I solved the problem as follows:

  $varCategory_rsgetsearch2 = "%";
  if (isset($_GET['Category'])) {
    $varCategory_rsgetsearch2 = $_GET['Category'];
  }
  $varMake_rsgetsearch2 = "%";
  if (isset($_GET['Manufacturer'])) {
    $varMake_rsgetsearch2 = $_GET['Manufacturer'];
  }
  $varColor_rsgetsearch2 = "%";
  if (isset($_GET['Color'])) {
    $varColor_rsgetsearch2 = $_GET['Color'];
  }
  $varPrice_rsgetsearch2 = "%";
  if (isset($_GET['Keysound_price'])) {
    $varPrice_rsgetsearch2 = $_GET['price'];
  
  }
  mysql_select_db($database_dBconn, $dBconn);
  $query_rsgetsearch2 = sprintf("SELECT * FROM products WHERE Category LIKE %s AND products.Manufacturer LIKE %s AND products.Color LIKE %s", GetSQLValueString("%" . $varCategory_rsgetsearch2 . "%", "text"),GetSQLValueString("%" . $varMake_rsgetsearch2 . "%", "text"),GetSQLValueString("%" . $varColor_rsgetsearch2 . "%", "text") );
  switch( $_GET['price'] ){
          case '0-500':
          $query_rsgetsearch2 .= ' AND price BETWEEN 0 AND 500 ORDER BY price ASC';
          break;
            case '500-1000':
          $query_rsgetsearch2 .= ' AND price BETWEEN 500 AND 1000 ORDER BYprice ASC';
          break;
                      case '1000-2000':
          $query_rsgetsearch2 .= ' AND price BETWEEN 1000 AND 2000 ORDER BY price ASC';
          break;
            case '2000':
          $query_rsgetsearch2 .= ' AND price BETWEEN 2000 AND 10000 ORDER BY price ASC';
          break;
  }
  
  $query_limit_rsgetsearch2 = sprintf("%s LIMIT %d, %d", $query_rsgetsearch2, $startRow_rsgetsearch2, $maxRows_rsgetsearch2);
  $rsgetsearch2 = mysql_query($query_limit_rsgetsearch2, $dBconn) or die(mysql_error());
  $row_rsgetsearch2 = mysql_fetch_assoc($rsgetsearch2);
  

  I'm sure you can keep checking the values, however for me the most was not necessary for this.

  Thanks for your help
