• How to check whether or not the value is already in the collection

  Hello
  
  I'm in the analysis of a donkey of xml file assigning values to the collection.
  For each new record, that I am available for capture of xml, I need to check if this value already exists in the collection or not, and then only I must add this value to the collection.
  How we do that. I am not able to check whether or not it is already present in the collection. Help, please.
  
  Here is my code
  
  
  TYPE tab_A_type_rec IS RECORD)
  Name Varchar2 (50);
  );
  
  TYPE tab_A_type IS TABLE OF THE tab_A_type_rec;
  
  pkv_A_tab tab_A_type: = tab_A_type ();
  
  
  l_nl: = dbms_xslprocessor.selectnodes (dbms_xmldom.makeNode (l_doc), ' / / List "");
  for cur_rec in 0... dbms_xmldom.GetLength (l_nl)-1 LOOP
  l_n: = dbms_xmldom.item (l_nl, cur_rec);
  
  pkv_A_tab.extend; -----
  pkv_A_tab (pkv_A_tab. (Last). Name: = dbms_xslprocessor.valueOf (l_n,'Name / text () '); -I have to do these two steps only after checking whther that value is already present in the collection pkv_A_tab or not... What will be the stated case.
  
  end loop;
  
  
  Thank you

  The only problem - cannot use SET operator nested table records ;) or even on a table nested objects, unless the object type has map/delivery orders. Now if in real life, record type has only one attribute - NAME OP can just create type of TABLE OF VARCHAR2 (50). Then:

  SQL> declare
    2      type tab_A_type is table of varchar2(50);
    3      pkv_A_tab tab_A_type := tab_A_type('A','B','C','A','B','C','D');
    4  begin
    5  if 'B' member of pkv_A_tab
    6    then
    7      dbms_output.put_line('Found B.');
    8  end if;
    9  pkv_A_tab := set(pkv_A_tab);
   10  dbms_output.put_line('List of distinct elements:');
   11  for i in 1..pkv_A_tab.count loop

• How to raise an event from the arrayCollection collection?

  I'm passing data from a model to a view in the following files. It works fine, but I want to send a message on the screen when an arrayCollection collection is filled. I know that I could create a custom event, but I do not understand why the eventhandler I created will not work. Please tell me what I'm doing wrong.

  You use "=" this is a reversal/replacement.  There is no chip

  assignment that will update.

  You could do

  model.databaseDataArrayCollection.source =

  Event.Result.Student.Task.source;

  That should translate into a CollectionEventKind.RESET in original HQ as it

  now a new set of data.

• How to tell if ObjectProxy contains the ArrayCollection collection or single object?

  When I retrieve data from a web service, the list contains an ArrayCollection collection. Within each collection ArrayCollection, the element can be a single object or a collection of objects theser ArrayCollection. It seems that FLEX provides what he thinks it's the ObjectProxy object type based on the number of children under the parent node.
  
  If the done ObjectProxy refers to an ArrayCollection collection, I want to iterate on it, but if she refres to a single object, I want to remove some of its properties.
  
  How do I tell at runtime if an ObjectProxy made reference to a collection ArrayCollection, or a single object? Thank you very much in advance!

• How to check whether or not a user session is null

  Hello
  
  I use Jdeveloper 11.1.2.2
  
  I have a some Junit test case execution use case, that's the problem I have:
  
  There's Junit tests that are written for some VO while tests of insert and update operation to Junit it is two General required columns Created by and updated by to engage in the database.
  These values are taken from the UserName of the current UserSession.
  
  So to get these values for each user, I thought to display a JPanel before the test is run, where the user enters the user name and password which is validated and the user is verified.
  
  First of all, I need to check if there is a session presents or not. To check this, I wrote a createUserSession() and liked on the inside:

  if(fixture.getApplicationModule().getSession().getUserData().isEmpty())

  Would that be to show the Jpanel and the details of the user and verify the user.
  
  But when executing the test itself, I found that the session is already present, now I just at the entry values based on who is the user.
  
  But Junit run the tests in the order in which the tests are written. I therefore call this in all the test cases.
  
  The Question is:
  How can I check if the session is already present or not, so that I don't have to ask the user every time of each test runs to enter the user name and password?
  
  Thank you
  Nigel.

  Hello

  ask yourself why you create test users and then automatically connect them as Jan Vervecken made in the net, I told him you. This way your test cases run without user intervention. To test if a session exists for a user, I would put a custom property in the user data. If this property exists, the user session is an existing one. However, make sure that the information you save user data survives passivation, because otherwise the information you get out of it is not accurate.

• check whether or not a concurrent request is complete the backend

  Hi all
  I want to check whether or not the competing applications is complete the backend using the API. I discovered that FND_CONCURRENT.wait_for_request can be used, but inside this procedure they use dbms_lock.sleep command to delay treatment. I used the same dbms_lock.sleep in my code, but does not correct results.
  Please you siggest me on solutions workaround that needs to be done to get the exact time of the concurrent request will have to fill.
  
  
  Thank you and best regards,
  Mahesh

  Hello

  You can get the same information in table FND_CONCURRENT_REQUESTS (API of FND_CONCURRENT of the readings of the same table).

  If you want to continue to use an API, see if you can use FND_CONCURRENT. GET_REQUEST_STATUS (Please check if it is a public API).

• Is it possible to search the ArrayCollection collection by index?

  Hi all

  I know, we can loop and compare each element of the ArrayCollection collection to get the correct item that we want. Obveriously, performance is going to hurt and it is not a wise method of search. Can we create an index for the key field of each item? Or any other class offering such a feature?

  Thank you

  When you say "a clue" are you talking like one in a table of database index?  That is something that can speed up a search?

  I'm trying to understand your desire and I think that what I hear, is that you have an ArrayCollection collection contains a number of objects.   When you want to find a particular object, you have found a way to locate the desired instance to browse each item in the collection ArrayCollection and ask "this element is equal to the key of the object I'm looking for?   I think that you are concerned by the amount of time it can take.

  Go back decades to my knowledge of computer science, this is an o(n) algorithm where n is the number of items in the table.

  Now, if there was an 'index' (ala databases) on the data, so if this index have been sorted, you would be able to find your match in O (log n)

  You can pay an O (n log n) cost the sort index when the data structure is created, but if you have a large number of research, then it can pay for itself.

  I'm not aware of any function that will help you on this out of the box (but that doesn't mean not there does not exist, only that I don't know about it.)

  I would like to also truthly ask yourself "is it worth the cost?   How many items you will have a typical table?  How often do you locate an entry in this table?

• Add a line of DataGrid using the ArrayCollection collection

  Work of one of these, when I hard code do it programmatically is not:
  
  Hard-coding approach 1 - *.
  var acData:ArrayCollection = new ArrayCollection();
  ...
  
  Each DataGridColum has a dataField like "col1", "col2", "col3", etc...
  Therefore, adding items like this works
  acData.addItem({col0:"testa",col1:"testb",col2:"testc",col3:"testd",col4:"teste"});)
  
  
  2 - programming approach *.
  But adding items like that does not work
  for (var j = 0; j < dataRows.length (); j ++) {}
  var t:String = [j] of dataRows m:System.NET.SocketAddress.ToString (); dataRows is of type XMLList, data are formatted as the format above
  I did a breakpoint to check and someone else watch the channel and it matches the format that works.
  acData.addItem (t);
  }
  
  When I try the second approach, I get all the content of the string in each cell of the grid, where, in the first approach, I get "tested" in the first column, "testb" in the second column (without quotes of course), etc...
  
  Anyone know why there is a difference or what I am doing wrong?
  
  Thanks in advance.
  
  
  

  I guess that's because in the second approach, you add a string to your ArrayCollection collection instead of an object as in the first approach:

  acData.addItem({col0:"testa",col1:"testb",col2:"testc",col3:"testd",col4:"teste"});) This is an object with the properties that you add to the ArrayCollection collection

  var t:String is dataRows [j] m:System.NET.SocketAddress.ToString ();. It is a string, not an object
  acData.addItem (t); you add a string to the ArrayCollection collection

  You must take your XML string and generate a new object, as in your first approach, using the End Sub

• Access table in the arraycollection collection and add the item at the end of the table

  for
  
  
  "login_user":"XXX"},i);
  
  //mess2=sess_MessArr[i2];
  //mess1=dispArray[i2].fwchat_message
  
  //searchArray(mess2);}
  
  
  
  
  
  (var i:int = 0; i< dispArray.length; ++i){
  
  dispArray[i]. 
  dispArray.addItemAt({
  

  
  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.
