• ArrayCollection collection all items in the string

  I'm trying to find all the vehicles that have a string of accessories.

  I have a string of seven comma optioncodes representing selectedItems among a list of options

  optionsString:String = leather, scratches,...

  I have an ArrayCollection collection called vehicleOptions that contains a list of vehicle options one line per option

  Wine1, optioncode

  Wine1, optioncode

  VIN2, optioncode

  VIN2, optioncode

  VIN3, optioncode

  ...

  I need to recover all vehicles (VIN) who, not one, but ALL the optioncodes in the string of optioncodes selected.

  Recommendations on how to do it?

  Once I have a list of wines, it enables me to filter another list of vehicles as vehicles with ALL options selected down the field.

  Thank you!

  Don

  If I understand your data, you would loop in the table to remember the last WINE you saw.  If you get through all the options for the WINE without a miss then it has all the options.

• collection ArrayCollection collection arraycollection assigned values from the original setting?

  Hi... I am pretty stumped on this one. Here's the situation... on my main flex app I define an arraycollection collection:

  public var fiscalYrsArray:ArrayCollection;

  The collection is filled with the results of a query to a CFC

  protected function fiscalYrs_resultHandler(event:ResultEvent):void {}

  for (var x: int = 0; x < event.result.length; x ++) {}

  If (event.result [x]. DATA == passData.filterFiscalYrs) {}

  Event.Result [x]. Assigned = true;

  }

  }

  fiscalYrsArray = event.result as ArrayCollection collection;

  }

  I have a main application with drop-down menus window (I use a multi-case combobox). I use this window as a filter window, where users can choose what they want filtered.

  on this component, I use a temporary arraycollection collection (b/c I don't want to change the assignments of the arraycollection the temp collection is based off of) which will be a copy of the fiscalYrsArray of the parentApplication collection:

  " < = xmlns:fx s:TitleWindow ' http://ns.Adobe.com/MXML/2009 'close = "PopUpManager.removePopUp (this)'

  xmlns:s = "library://ns.adobe.com/flex/spark" title = "filter data" creationComplete = "initComp (); »

  xmlns:MX = "library://ns.adobe.com/flex/mx" width = "400" height = "300".

  xmlns:multiPickBox = "Components.multiPickBox. *" >

  < fx:Declarations >

  <! - Place non-visual elements (e.g., services, items of value) here - >

  < / fx:Declarations >

  < fx:Script >

  <! [CDATA]

  Import mx.collections.ArrayCollection;

  Import mx.controls.Alert;

  Import mx.managers.PopUpManager;

  private var tempfilterFiscalYrs:String

  [Bindable] private var fiscalYrDP:ArrayCollection = new ArrayCollection collection;

  private function initComp (): void {}

  fiscalYrDP = parentApplication.fiscalYrsArray;

  tempfilterFiscalYrs = parentApplication.passData.filterFiscalYrs;

  }

  protected function msc_addItemHandler(event:Event,filterVal:String,comboId:String):void

  {

  Alert.Show ("get here '");

  This [filterVal] = ";

  {for each (var point: Object in {this [comboId] .selectedItems)}

  This element of += [filterVal] ['DATA'] + ",";

  }

  filterChange = true;

  idText.text = str;

  }

  I am lie the collection arraycollection filterYrDP to a custom choice multi combobox:

  < multiPickBox:CheckCombo id = "fiscalYearF" width = "162" dataProvider = "{fiscalYrDP}".

  addItem = "msc_addItemHandler (event, 'tempfilterFiscalYrs', 'fiscalYearF')" "

  allIndex = '0' x = "77" y = "17" labelField = "DATA" / >

  However, I find that when an element is activated the assigned = true value is actually applied to the fiscalYrsArray of my parentApplication origin. I just want the assigned = true to apply to the fiscalYrDP collection arraycollection (one that is based on the fiscalYrsArray of parentApplication). How could it be written back and changing the properties of a fi main is just a temporary copy?

  By assigning the table using "=" you are just assigning the same table - in the same memory location.

  If you want to keep a separate table, you use the function ObjectUtil.copy

  import mx.utils.ObjectUtil;
  
  arrNewData  = new ArrayCollection();
  arrOldData  = ObjectUtil.copy(arrNewData) as ArrayCollection;
  

• Type was not found or was not a compilation constant: ArrayCollection collection

  I've never seen this type of error before. I was running the asdoc tool when I arrived at the Office:

• Cast of XML for the ArrayCollection collection where there is a single record

  I work with web services and in the result handler doing the following

  protected function WbSc_SSPr_PrinterListResult_resultHandler(event:ResultEvent):void
  {
  printerlistArrayCollection = event.result.Printer as ArrayCollection collection;
  PrinterCount = printerlistArrayCollection.length - 1;

  If there is more than one value it works fine.

  If only one value is returned, then it shows as nothing.

  Huh?

  When I run it as a test, it returns a record

• How to check whether or not the arraycollection collection is initialized

  Hi all

  I am bit new to use the collection arraycollection in flex. I'm having this particular scenario, where I get Server data in a table. So I have to check if the arracollection I created is initialized or not. If it is not initialized I need to initialize it or other wise, just add collection from table to table. Here is the code snippet

  currentTrajectory = new collection ArrayCollection (event.result as Array);

  var _multiTrajectoryEvent:MultiTrajectoriesEvent;

  _multiTrajectoryEvent = new MultiTrajectoriesEvent (MultiTrajectoriesEvent.DRAW_AUTO_TRAJ);

  If (!) (_multiTrajectoryEvent.trajectories.source is nothing))

  {

  _multiTrajectoryEvent.trajectories.addItem (currentTrajectory);

  }

  else

  {

  _multiTrajectoryEvent.trajectories = new ArrayCollection ([currentTrajectory]);

  }

  But unfortunately the above code does not work for me, because the arraycollection collection is not initialized first, there is no way of checking me if it is initialized later or not as the compiler gives me the error checking to null...

  Can any Walter suggest how can I check if the table collection is initialized or not?

  I would appreciate any suggestions and thouhgts for the same

  Thank you

  Akshay

  Sorry to say, but it's not the right approach...

  I'm abt don't know what is exactly done so I'll give a generic example...

  I have an ArrayCollection collection...

  private var arrC:ArrayCollection;

  Maybe it's getting used internally in several places, so you be sure if she be initialized already or not. Then use a code something like that...

  If (arrC! = null & arrC.length > 0)

  {

  ...

  ...

  }

  If you are using

  If (arrC.Length > 0)

  {

  ...

  ...

  }

  and it is not initialised it will give exceptional at the time to compile...

  For a logic if(a && b) be true both a and b must be true, so if same first one (a) is false it will not evaluate the second logic (b).

  Thus, the previous logic works.

• How can I convert an arraycollection collection put an XmlList as a dataprovider for ADG

  I have an arraycollection collection that I get from the backend. I need to convert XMLList with knots, because I need to show data such as the branches of the ADG.

  now I use grouping but get a lot of sorting problems. So I want to convert XmlList to show the data as it is.

  is it possible to manage this problem?

  Example of sample can be enjoyed.

  Fasten your arraycollection collection and create your own xml file.

  var arr:ArrayCollection = your arraycollection;
  var xml:XML = ;
  
  for each( var i:Object in arr ){
       xml.appendChild(  {i.value}  );
  
  }
  
  var xmlCLT = new XMLListCollection( xml..node );
  

  Or you can put code in the itemrenderer to analyze the property data, so you can use your arraycollection collection directly.

• Object to an ArrayCollection collection

  Hello

  I have an application that supports some info from database and he sinks into a datagrid, or a chart.

  I met this error to have one line and try to use it in a table so that I can use in my application.  Its come to my attention that it is a quite common problem that people face, but I don't seem to be able to get around any one test.

  My actionscript has a function that trots through ASP database and returns the data in the case - as below (obv I deleted stuff - load of calls are made to the mssqlQuery function - the only one I have trauma with is below)

  mssqlQuery ("SELECT (CASE SLARag, COUNT (SLARag) as Volume [CMI_ClientMI]. [Portal]. [BatchUpdate]","BusSegBuildSummary") ;}

  public static void mssqlQuery(sql:String,fid:String):void {}

  var http:HTTPService = new HTTPService;

  var parm:Object = new Object;

  parm.fas_sql = sql;

  parm.fas_db = mssql_db;

  http.url = mssql_url + "? irand =" + Math.random ();

  http.showBusyCursor = true;

  http.request = sql;

  http.addEventListener (ResultEvent.RESULT, mssqlResult);

  http.addEventListener (FaultEvent.FAULT, mssqlFault);

  http.method = "POST";

  sqlToken = http.send (parm);

  sqlToken.param = fid;

  }

  For BusSegBuildSummary collection arraycollection var

  [Bindable]

  public static var _BusSegBuildSummary:ArrayCollection = new ArrayCollection();

  
  

    

  Case statement to BusSegBuildSummary

  case 'BusSegBuildSummary':

    

  
  

  If (event.result.results.record is ObjectProxy) {}

  trace ("this is a Proxy object");

  
  

  }

  else {}

  trace ("it isn't Proxy object");

  _BusSegBuildSummary = event.result.results.record;

  }

  break;

  So - if the result has several records in it - so we are very well - it's the trace ("this is Proxy object"); bit which is annoying.

  I think I have to send the object as an arraycollection collection and I tried a number of different ways without success.

  Any ideas? I struggled for a while now and I am panicing!

  Hi Andrew

  No problem with the warranty so I wanted just report to disseminate good practices

  I do not understand what you write, but it is how I read it:

  When the user runs the function again, you get a more added slice, you can don't wan't, only you don't wan't the new?

  This is because you don't collection.addItem (item), so just add the to it to the collection.

  If you need to do:

  If (event.result.results.record is ObjectProxy)

  {

  collection.removeAll ();

  collection.addItem (event.result.results.record)

  }

• Labelling of records in an array or arrayCollection collection

  Many of the Tour de Flex examples use a table in a way that is not familiar to me. For example: var array: Array = [{Profit: 2000}, {Profit: 2400}];

  I want to put my data in the table as follows: var array1:Array = [2000,2400];

  but I still want to be able to access the property of 'Profit' when I use an ArrayCollection collection as in the example below.

  So, I have 2 questions:

  First of all, what is the name given to filling a table like: var array: Array = [{Profit: 2000}, {Profit: 2400}];

  and

  Second, how to tag my data with "Profit" when I add it to an array or ArrayCollection collection?

  Thanks for your time.

  Hi SiHoop,

  You need to defenitely label it when you're assiging the data for the table itself.

  var array: Array = [{Profit: 2000}, {Profit: 2400}];

  That the above is equivalent to creating an object and pushing data to a table.

  You can use the above statement as... goes

  var array: Array = new Array();

  var obj:Object = new Object();

  obj. Profit = 2000;

  Array.push (obj);

  obj:object = new Object();

  obj. Profit = 2400;

  Array.push (obj);

  In fact {Profit: 2000} represnts an object... including the benefit's label (property of the object) to the value.

  var array: Array = [{Profit: 2000}, {Profit: 2400}]; is the easiest way to initialize the array. You need to label it until then only you can access it with the label.

  Thank you

  I have this code to try to access the values in the table in the arraycollection collection, but that's not it actually creates a value at the end of the arraycollection collection. can someone tell me what im doing wrong I basically want retransmits the individual tables in the arraycollection collection and add Login_user

  So, I guess your ArrayCollection collection holds an array of objects, as follows:

  public var myAC:ArrayCollection = new ArrayCollection([{first:"bob",last:"smith"},{first:"jim",last:"jones"},{first:"mary",last:"allen"}]);
  

  And you try to add a new property of login_user to each of them, right?

  for each (var obj:Object in myAC) {
       obj.login_user = obj.first + "83";
  }
  

  Each person would be firstly, properties last and login_user.  In my example above, all the login_user would set their name + number 83, so adjust you accordingly for your application.

  It is the ease (for each rock for this situation).  However, if you want to paste the iterative approach, you have published, you can try this:

  for (var i:int = 0; i < myAC.length; i++) {
       myAC.getItemAt(i).login_user = myAC.getItemAt(i).first + "83";
  }
  

  I think that the for each syntax is clearer, but anyway works the way I think you want.

• Export the ArrayCollection collection in XML file

  Hi all

  Is it possible to export a Flex ArrayCollection collection to an XML file.

  < cue >
  "< question section =" "start =" "stop =" "/ >
  "< question section =" "start =" "stop =" "/ >
  "< question section =" "start =" "stop =" "/ >

• What is the need to sort an ArrayCollection collection?

  Hello

  But can you get it someone please let me know why there is easy sort of the ArrayCollection collection?

  Where this might be useful? because insofar as my collection ArrayCollection knowledge would be used as a dataprovider to a DataGrid and datagrid already has a facility for sorting according to the column header clcik.

  So why or where Mecahnism type is used in the ArrayCollection collection?

  
  Please apologize if the question is stupid.

  Please share your ideas.

  In fact, the DataGrid type use sorting the Collection, she uses as a dataProvider, which means that the type of collection ArrayCollection is used if the dataProvider is an ArrayCollection collection.

  It can also be useful when you need to process an ArrayCollection of the elements collection in a particular order. Sorting the collection ArrayCollection using a for each loop to process the data in the correct order.

• ArrayCollection collection do not fill after calling first Data Services

  I am filling a collection ArrayCollection using a call for data by the following code:

  [
  Bindable]
  
  public var srv:RemoteObject;
  
  var acCountries:ArrayCollection; 
  
  if
  
  
   (srv == null){srv = 
  new RemoteObject();srv.destination = 
  
  "trip"; }
  acCountries = srv.getAllCountries.lastResult;
  srv.getAllCountries();
  
  
  
  

  ArrayList is not populted during the first call.  The java backend data service method is called, but the ArrayCollection collection is not populated until the time of the second (or third) the code is executed.

  I tried to walk through the debugger, but it is unclear what I does not initialize correctly.

  Hello

  Try to use the below approach instead of the adopted approach.

  [

  Bindable]

  public var srv:RemoteObject;

  private function getAllCountries():void

  {

  var acCountries:ArrayCollection;

  if (srv is Nothing)

  {

  SRV =

  new RemoteObject;

  SRV.destination =

  'journey';

  }

  srv.addEventListener (ResultEvent.RESULT, countriesResultHandler);

  srv.addEventListener (FaultEvent.FAULT

  countriesfaultHandler);

  srv.getAllCountries ();

  }

  private function countriesResultHandler(result:ResultEvent)

  {

  Check here the result by debugging object and replace the threshold accordingly

  acCountries = result.countries;

  }

  private function countriesfaultHandler(fault:FaultEvent)

  {

  Alert.Show)

  "Error: ' + fault.message);

  }

  In the approach you used you bind the data to the ArrayCollection collection by making use of the lastResult object.

  But you use the below line and send the result at the same time...

  acCountries = srv.getAllCountries.lastResult;

  srv.getAllCountries ();

  Here you don't know when the acCountries arraycollection collection will be linked to the lastResult object. Given that it is an asynchronous operation for the first time that you control the acCountries arraycollection collection you have all the data. Her approach always better and good use of event handlers in response as the way I used so that you will know exactly when took place the answer/result and if no fault or so.

  If this post answers your question or assistance, please mark it as such.

  Hope this will make things clear...
