• & quot; data binding will not be able to detect assignments & quot; warning

  new features in Flex Builder 3, Beta 2 (I did not have this problem with Beta 1), I have randomly (it seems) get warnings "data binding will not be able to detect assignments to < property >" for properties that are Bindable. If I run my AIR application while I have these warnings the app will not be able to detect assignments to these properties, as warning says. However do a rebuild/clean removes these warnings and my app then works well, with data binding works as expected. I have not found a way to force this behavior, it seems just occur occasionally during development.
  
  others have this problem?

• &amp; quot; data binding will not be able to detect assignments &amp; quot; alert - but no runtime error

  I have a class that is instantiated as hhgrab, it has an array declared as:
  
  [Bindable]
  public var resultData:ArrayCollection = new ArrayCollection();
  
  In my MXML file I link this table to a datagrid as:
  
  < mx:DataGrid = "19" x y = "283" width = "383" dataProvider = "{hhgrab.resultData}" >
  
  But I gives me a warning that says "data binding won't be able to detect assignments to the hhgrab.
  
  I Googled it and saw that this alert is raised when a variable is not declared as bindable, but mine is. This could be a bug in Flex Builder 3?
  
  Thank you...

  I did hhgrab is bindable:

  package components
  {
  public class MyAC
  {

• Data binding will not be able...

  I have a piece of code, and it throws the infamous "Databinding will not be able to detect... "Here is the code, alert is thrown to the TextInput statement line.  I guess it has something to do with the way the VM creates components and adds event listeners, but I'm not sure.  My work current around is to change the includeInLayout and mouseChildren property, but that feels kind of hackers.  Any help is greatly appreciated.

  The alert is lifted to the TextInput

  I'll go with the simplistic approach and ask why not defining textString as follows:-

  [Bindable]

  public var textString:String

  There is probably a good reason, but you don't talk about...

  Is she related to the '@' sign that you added to the link? What is the purpose of using it?

• "Data binding will be not able to detect the transfer..." "while [bindable] is set.

  Hello world

  Thank you for taking some time to try to help me.

  I get the warning "data binding will not be able to detect the assignment... "for a

  Collection ArrayCollection all [bindable] properties are set correctly - at least I think... ;-)

  [bindable]
  private var allParties:ArrayCollection = new ArrayCollection();
  

  and then, later:

                 <s:DropDownList id="dropDownList_party_sprecher1"
                                                          [...]
                                     labelField="_internal_partyname">
                      <s:AsyncListView list="{allParties}"/>
                 </s:DropDownList>
  

  The elements of the array collections are a custom class to the mine, which has been automatically

  generated by the php flash builder Gizmo service. This class is also marked as [bindable]:

  [Bindable]
  public class Parties extends _Super_Parties
  {
       [...]
  }
  

  and the extended with class

  [Managed]
  [ExcludeClass]
  public class _Super_Parties extends flash.events.EventDispatcher implements com.adobe.fiber.valueobjects.IValueObject
  {
  [...]
  
       [Bindable(event="propertyChange")] 
      public function get idx() : int    
      {
              return _internal_idx;
      }    
       [Bindable(event="propertyChange")]
      public function get partyname() : String    
      {
              return _internal_partyname;
      }  
  [...]
  }
  
  As I understand it, the [Managed] makes the whole class 
  [bindable] as well and the getters are marked too.
  I've put the [bindable] keyword anywhere I could imagine 
  but it doesn't help at all.
  In principle I wouldn't mind the warning, but the 
  dropdown-list doesn't work.
  
  Please let me know if you need any more information,
  
  Thanks

• Data link won't be able to detect assignments to the...

  Hello
  
  I've got this warning:
  Data binding will not be able to detect assignments 'Name '.
  for this line:
  < mx:TextInput = "200" x = "10" name = "prodnr" text = "{theService1.lastResult.queryResult. (@name=='product_item').item.prodnr}"/) >
  
  If I do not use (@name == "product_item") condition, there is no caveat, so this seems very well:
  < mx:TextInput x = "200" y = "10" name = "prodnr" text="{theService1.lastResult.queryResult.item.prodnr}"/ >
  
  LastResult XML looks like this:

  Someone knows why this warning?
  

  Try to use the method of the attribute.

  Text = "{theService1.lastResult.QueryResult. "{(attribute ('name')) == 'product_item'). item.prodnr}.

  I think that will get rid of your warning.

• Data binding does not detect changes

  During the passage of property that may be related to the function and assigning a new object data binding breaks
  Take a look at the following example.
  
  <? XML version = "1.0" encoding = "utf-8"? >
  "" < mx:Application xmlns:mx = ' http://www.adobe.com/2006/mxml ' layout = "absolute" initialize = "init ()" >
  
  < mx:VBox >
  < mx:Text id = text = "{user.name"textbox"}" / > "
  < mx:Button label = "Update user" click = "updateUser (user)" / > "
  < mx:Button label = "Update User2" click = "updateUser2 ()" / > "
  < / mx:VBox >
  < mx:Script >
  <! [CDATA]
  [Bindable]
  private var: user;
  
  private function init (): void
  {
  User = new User();
  User.Name = "first name";
  }
  
  private void updateUser(newUser:User):void
  {
  newUser = new User();
  newUser.name = 'new name ';
  }
  private function updateUser2 (): void
  {
  User = new User();
  User.Name = "new Name2";
  }

  < / mx:Script >
  < / mx:Application >
  
  File User.as
  package
  {
  [Bindable]
  public class User
  {
  public var name: String;
  }
  }
  
  Why the function updateUser break data binding?
  The updateUser2 function works

  Thanks for all replies ;)

  Suggestion of levancho on sends an event seems good to me.

  This could look like this:

  var userEvent:UserEvent = new UserEvent ("new user", newUser);
  dispatchEvent (userEvent);

  Where UserEvent is an event with the new object.
  Then all the elements that need this change pourraient, follow these steps:

  addEventListener ("new user", userChanged);

  private void userChanged(evt:UserEvent):void
  {
  evt. User; Update the link with the new user...
  }

  After looking more on the problem, I found:
  Initially, the main problem was that the variable in the function will not update the refence sent in the function when you create a new instance, regardless of the use of data binding or not...

• Date field will not update

  Apex using pre-packaged "Group calendar" app I work on page 10. I updated the form to include a custom date field and added all the code to the EBA_ca_api package

  My problem is that my custom date field will not retain the value on the edition of an event. I have other custom fields that are not date fields (field numbers and text) that update without any problem...

  How can I update my date fields?

  Update:

  I am sure that the issue is somewhere in the package, the values are not updated for some reason any.

  The pre-existing app code uses this statement

  If to_char()c1.event_date_time,' DD-MON-RRRR HH:MIam ') ! = TO_CHAR ()p_event_date_time ' DD-MON-RRRR HH:MIam '( ) then

  Update EBA_ca_events

  set event_date_time = p_event_date_time

            where event_id = p_event_id ;

        end if ;

  
  

  and it works for this field when updating. I tried to use this code on my custom date field and it didn't work, so now I'm looking for something like this

  if TO_CHAR (nvl(c1.event_due_date,'0')) ! = TO_CHAR (nvl(p_event_due_date,'0')) then

  Update EBA_ca_events

  set event_due_date = p_event_due_date

             where event_id = p_event_id ;

  end if ;  -Copy the following code causes an error when you try to apply changes (not a month valid)

  
  

  Because the following code works and updates to my date no fields

  
  

  If nvl(c1.event_not1,'0')! = nvl(p_event_not1,'0') then

  Update EBA_ca_events

  Set event_not1 = p_event_not1

  where event_id = p_event_id;

  end if;

  Does the code work if I'm on the right track? -At the end of the day what I'm trying to do, it is to be able to add a date field for the application of group calendar pre-packaged on the creation form and event on page 10, and then later change this event and updated it to the database.

  
  

  Richie V wrote:

  No I did not, but do you know how to fix the error happen and allow the new field custom_date to be edited and saved in the database?

  Thereafter. The missing pieces of the puzzle were the type of the values concerned was TIMESTAMP WITH LOCAL TIMEZONE, and that type conversion had already been made in the process of page APEX. Therefore, the required code in the package:

  -- custom date code
  
  if nvl(to_char(c1.custom_date,'DD-MON-RRRR HH:MIam') , 'X')!= nvl(to_char(p_custom_date,'DD-MON-RRRR HH:MIam'), 'X')
  then
      update EBA_ca_events
      set custom_date = p_custom_date
      where event_id = p_event_id;
  end if;

• Data binding does not seem to work

  I have a report with 3 queries - a mother and two children. (In fact, there are more than 2 children, but only 2 of them are at the origin of the problem.) The current version of the report uses frames/repetition, overlapping frames and fields for each request of the child, which makes it almost impossible to change - and I need to change.
  
  I wrote a query that joins the two children in a single request. It works in SQL * more when I add the where clause that expected be added by data - links, but when I run the report I get the same results as when I run it in SQL * Plus without the data where a clause link. So it seems data links do not work for this game of parent/child of queries.
  
  No idea why? (Reports 6i)
  
  It is certain that data binding is the problem. I did the new 'child' an independent query, adding where clause to the query and deletion of data links between the parent and the child, and that is work - at least for the case where the parent returns a single record. I really need that data links work well, then re - asks the child for each parent. On the other hand, report editor showed a strange icon on the request of the child. It seemed to me the icon of data link with a slash through it--and he disappeared when I deleted the data bindings, so I'm sure that the icon showed that data links were not working. He didn't explain why.
