I Unable to bind a data provider to a TREE component

I know this should be easy, but I am trying to switch the following
myTree.dataProvider=event.result;
to
private var treeSource:XML;
treeSource = event.result;
myTree.dataProvider = treeSource
BUT, no matter what XML type I use I keep getting a compilation error 1118: Implicit coercion of a value with static type Object to a possibly unrelated type XML. Obviously I am missing something.

I have the solution.
var xmlList:XMLList = XML(event.result).node;
myXmlList =
new XMLListCollection(xmlList);mainTree.dataProvider =
new XMLListCollection(xmlList);

How to bind BubbleSeries data provider?

Hi,
I have a bubbleChart and multiple bubble series inside it. Initially I set the data provider of each of my series. Later, when I update the array collections (to which my bubble series's data provider was binded), bubble series' data provider is not updated.
<mx:BubbleChart>
     <mx:BubbleSeries dataprovider={arr[0]}>
     </mx:BubbleSeries>
     <mx:BubbleSeries dataprovider={arr[1]}>
     </mx:BubbleSeries>
     <mx:BubbleSeries dataprovider={arr[2]}>
     </mx:BubbleSeries>
</mx:BubbleChart>
In actionscript, arr[0],arr[1] and arr[2] are updated. I want to see updated bubbleseries too, but in vain.
I have marked arr as bindable.
Please help..
Thanks,
Tanu

Hi Tanu Jain,
If you have no problem updating the values there itself.. then you can do one thing...But the way you are trying to update the things is however correct but it will not update the values for BubbleSeries. The reason is why because the each object and its properties in the expenses array collection are not Bindable as since the objects in the expenses array collection are generic objects.
In order to make the objects bindable you can make use of a seperate class and make all the properties Bindable as needed so that you can acheive things you needed.
And one more thing here to note is ...when you are assiging the dataProvider the first time in the for loop you are using the below line of code...
bubbleSeries.dataProvider = expenses.getItemAt(i);
But in the click handler you are reassigning the dataProvider as expenses = expenses1; by doing so you are assigning/adding new items to your expenses ArrayCollection but the binding you assigned to the bubbleSeries dataProvider are different items so there is no possibility of updating the values to the BubbleSeries by this approach so you should update the values there itself by making use of external Bindable class so that Bubble Series gets updated correctly.
Actually I got this sorted out yesterday itself but you said as you are having some 200 - 300 series it is taking more time delay to get updated by reassigning the dataProvider by looping through the series as I suggested in my previous post. By updating the values there itself say if you have some 300 - 400 rows in your expenses ArrayCollection then you need to loop through all the rows(300 - 400 times) and update all the properties within that Object.
Any way try this example below which I am explaining above...hope this is less expensive when compared to reassigning the dataProvider again..

Need help coneverting data provider for inline fx:Component renderer for a datagrid

I want to use an existing inline item renderer and point the hard coded data provider to an arraycollection, which comes from a database.
At firt glance this looks easy, just change
<fx:Declarations>
<fx:Component id="inlineEditor">
   <mx:ComboBox >
    <mx:dataProvider>
     <fx:String></fx:String>
     <fx:String>AIG</fx:String>
     <fx:String>BHN</fx:String>
     <fx:String>FH</fx:String>
     <fx:String>LM</fx:String>
     <fx:String>SD</fx:String>
    </mx:dataProvider>
   </mx:ComboBox>
</fx:Component>
</fx:Declarations>
TO
<fx:Declarations>
<fx:Component id="inlineEditor">
   <mx:ComboBox
    dataProvider="{outerDocument.wripAttachTypeAc}"
    labelField="WRIP_ATTACHED_FILE_TYPE_DESC">
   </mx:ComboBox>
</fx:Component>
</fx:Declarations>
BUT that does not work the data grid produces the object.object value as theres no association to the labelField . Can anyone see what I am doing wrong. The datagrid entry is
<mx:DataGridColumn dataField="Permit File"
          width="150"
          editorDataField="selectedItem"
          itemEditor="{inlineEditor}"/>

Thanks Harui, but it doesn't help. If the border is set it will help, but the very big problem is the empty rows that appear at the end of the datagrid... I can't find a way of measuring correctly the height of the itemRenderers!
I'll update this thread if I manage to do it.

Bind a data on a Tab set component

Hello all people!
Sorry for my dirty English!
I've created a little intranet and would use a tab set component for a view of the data in mysql datasource!
But if I put in the tab set the Property Sheet component and bind it to dataProvider, the init() of the java file not run!
Can I use the propety sheet with tab set?
If the response is "YES"; Why this don't work?
Also I did use a page fragment for any tab?
thank's a lot!

I need more info. A property sheet is a container just like group or grid but its structured into layers: Property Sheet, then Property Sheet section, and then Property.
Property's are ment to contain one or more components. There is a bug that you cannot drag/drop a component right on a property, you have to use the outline window to get them there).
What exactly did you bind to in the property sheet component? Which part? What other fields are on the tabs?
Please add a MessageGroup component to the page and re-run to see if you get any errors that may help..
Thanks,
Lark

ArrayCollection as Data Provider in Tree

Hi,
     Does anybody know how to use ArrayCollection as a data provider in tree control as i have to access the data later from the database. I'm able to use XMLList as the data provider in the tree control but unable to use ArrayCollection as data provider.
Please help me in this.
Thanxs
Gaurav

Actually I was just thinking about something I am currently doing. I am not sure if a tree control will accept a HierarchicalData object as its dataprovider but what you can do is create an array of associative arrays where one of the keys is called children. This key called children would then point to another associative array. It could nest down as far as you want but would look absolutely terrible. I still think XMLList is the way to go but if you really dont want to do that you can try and work this. Here is some sample of what a simple HierarchicalData object looks like:
private var masterData:Array = [
             { OrderId: 10248, CustomerId:"WILMK", EmployeeId:5, OrderDate:"1-Feb-2007",
            children:[
                        {ProductId:11, ProductName:"Quesbo Cabrales", UnitPrice:14, Quantity:12, Discount:0, Price:168},
                        {ProductId:42, ProductName:"Singaporean Hokkien Fried Mee", UnitPrice:9.8, Quantity:10, Discount:0, Price:98},
                        {ProductId:42, ProductName:"Mozzarella di Giovanni", UnitPrice:34.8, Quantity:5, Discount:0, Price:174}
             { OrderId: 10249, CustomerId:"TRADH", EmployeeId:6, OrderDate:"3-Feb-2007",
                 children:[
                    {ProductId:51, ProductName:"Manjimup Dried Appels", UnitPrice:42.4, Quantity:40, Discount:0, Price:1696},
                    {ProductId:14, ProductName:"Tofu", UnitPrice:18.6, Quantity:9, Discount:0, Price:167.4}
             { OrderId: 10250, CustomerId:"HANAR", EmployeeId:4, OrderDate:"4-Feb-2007",
                 children:[
                    {ProductId:51, ProductName:"Manjimup Dried Appels", UnitPrice:42.4, Quantity:35, Discount:0.15, Price:1261},
                    {ProductId:41, ProductName:"Jack's Clam Chowder", UnitPrice:7.7, Quantity:10, Discount:0, Price:77},
                    {ProductId:65, ProductName:"Hot pepper Sauce", UnitPrice:16.8, Quantity:10, Discount:0.15, Price:214.2}
I got this example from a tutorial online explaining how to use nested AdvancedDataGrids but hopefully you can see my point on how you could nest the "nodes" in their parents children object. It has to be called children because the data object is defaulted to look there. If you created this type of Array all you would have to do then is:
var hierData:HierarchicalData = new HierarchicalData(masterData);

Populating a Tree data provider dynamically

Hi,
I have made an XMLLIstCollection as the data provider of a
Tree control. I want to add the tree nodes dynamically. Now the
problem is that I am able to add a node to the collection but not a
sub-node. Can anybody plz tell me the way to do it?

I tried with your code the following mxml program:

public var xmlIn:String = "<node label='new'/>";
public var xmlNode:XML=new XML(xmlIn);

coll.addItem(xml);
xml=<node label="sdf">{xml}</node>;

The hosted demo here tells that we can add the same menu model to a tree component...
http://jdevadf.oracle.com/adf-richclient-demo/faces/components/pagehierarchy/page.jspx?_afrLoop=14156998585414802&_afrWindowMode=0&_afrWindowId=null
Is it possible to bind a menu model to a Tree component? If possible...how to achieve this? If not...Is there any other way we can display the application menu in the form a tree...using the existing menu models?

Hi,
I don't understand your question. You simply can use the tree and specify the MenuModel as its value and define the right detailStamp, like any kind of tree. Or was your question more general like how to use a tree?

Can anyone help abt this problem? I wud very thankful for them.

Hi,
Can you post the wsdl URL. It would be of great help if we could have a look at the wsdl schema. Not all schemas are supported at the moment and hence the error. You can have a look at the limitations section in the documentation guide.

Unable to create or update the Excel Personal data provider in Web Rich

Hi All,
Iam getting the below error message ,when iam using Excel as personal data provider in WEBI Rich Client.
"Unable to create or update the Excel Personal data provider in Web Rich Client Cannot open the workbook WIS:10872"
Please suggest a solution ,it helps a lot..
Regards
Mahesh

Hi,
Was this issue resolved? I see this post has been marked answered but there wasn't any information on what it took to resolve the issue.
We have our CMS and processing servers on Linux while our Scheduling servers are on Windows. The WEBI reports with external data providers fail to run on Infoview/ scheduler.
We were told this is addressed in FP 3.6 but that is not the case. We installed FP 3.6 but still continue to see these errors. It required us to manually deploy the ExtensionFactoryService package for enabling the refresh of such reports on infoview/schedulers. It also involves placing of the file used [.xls/.txt] on the linux server on the PersonalDPFiles directory.
No luck so far!!!
Any help would be greatly appreciated!
Thanks

Unable to use transactions with System.Data.OracleClient data provider

I am using VS2008, System.Data.OracleClient, Oracle 10g, and ODAC 10.2.0.20. I haven't been able to get transactions to work. When I use 'connection.BeginTransaction()', the rollback doesn't work. When I use TransactionScope, the output parameter is always DBNull. Any ideas/comments?
Here's the sample code:
// #define ENABLE_TRANSACTION // failure is 'rollback not working'
#define ENABLE_TRANSACTION_SCOPE // failure is 'no output parameter value'
using System;
using System.Collections.Generic;
using System.Data;
using System.Text;
using System.Data.OracleClient;
#if ENABLE_TRANSACTION_SCOPE
using System.Transactions;
#endif
namespace TestOracleTransaction
class Program
static void Main(string[] args)
#if ENABLE_TRANSACTION_SCOPE
using (TransactionScope scope = new TransactionScope())
#endif
string connectionString = "Data Source=ORADEV;User ID=user;Password=pwd";
using (OracleConnection connection = new OracleConnection(connectionString))
try
connection.Open();
#if ENABLE_TRANSACTION
using (OracleTransaction transaction = connection.BeginTransaction())
#endif
try
#if ENABLE_TRANSACTION_SCOPE
if (Transaction.Current == null)
throw new ArgumentException("no ambient transaction found for OracleClient");
#endif
OracleCommand command = connection.CreateCommand();
#if ENABLE_TRANSACTION
command.Transaction = transaction;
#endif
command.CommandType = CommandType.StoredProcedure;
command.CommandText = "TIS.P_TIS_GATEWAY_INFO_ADD";
OracleParameter param = command.CreateParameter();
param.ParameterName = "p_gateway_id";
param.Direction = ParameterDirection.Input;
param.DbType = DbType.Int64;
param.Value = 18;
command.Parameters.Add(param);
param = command.CreateParameter();
param.ParameterName = "p_info_id";
param.Direction = ParameterDirection.Input;
param.DbType = DbType.Int64;
param.Value = 79;
command.Parameters.Add(param);
param = command.CreateParameter();
param.ParameterName = "p_user";
param.Direction = ParameterDirection.Input;
param.DbType = DbType.String;
param.Value = "spms";
command.Parameters.Add(param);
param = command.CreateParameter();
param.ParameterName = "p_gateway_info_id";
param.Direction = ParameterDirection.Output;
param.DbType = DbType.Int64;
param.Size = sizeof(Int64);
command.Parameters.Add(param);
int count = command.ExecuteNonQuery();
object value = command.Parameters["p_gateway_info_id"].Value;
long id = (value == DBNull.Value) ? -1 : Convert.ToInt64(value);
if (id < 0)
// FAILURE - no output parameter value when TransactionScope enabled
throw new ArgumentException("no return value");
#if ENABLE_TRANSACTION
// FAILURE - rollback doesn't work when Transaction enabled
transaction.Rollback();
#endif
#if ENABLE_TRANSACTION_SCOPE
scope.Complete();
#endif
catch (Exception ex)
System.Console.WriteLine("ERROR: " + ex.Message);
#if ENABLE_TRANSACTION
transaction.Rollback();
#endif
finally
if (connection.State == ConnectionState.Open)
connection.Close();
}

Hi,
First, this is not the place for questions with System.Data.OracleClient, this is the Oracle Data Provider for .NET forum. Having said that I went ahead and tested your code with some slight modifications because you did not provide the stored procedure information. I am assuming your stored procedure is doing some sort of DML since you are using transactions and attempting to commit and rollback.
I tested the following with both Transaction scope and a local transaction object and it worked fine with System.Data.OracleClient. I provided the create table and stored procedure I used.
Observations
========
When using transaction scope, a distributed transactions was executed and the data was inserted and returned in the output variable.
From console
p1 value is Hello World
From SQL Plus
SQL> select * from foo;
C1
Hello World
When using a local transaction, the DML was not inserted when calling rollback and when I changed it to commit, the row was inserted successfully.
Maybe you can test the simple foo example below to see if it works for you. Maybe there is something going on in your SP that is causing your specific observations.
The code I posted at this point is using local transaction and calling transaction.commit(), rollback is commented out. But I tested all scenarios and they worked as expected.

Binding Text input value to chart data provider

Hello, I am trying to develop a flex mobile application that generates the Chart.
Is there any way to set the text input value as a chart data provider?????
and if so, can you give me example?????

Perhaps a stupid question but when you change your
arraycollection do you do arraycollectioname.refresh()? If not,
that should be your problem, without the refresh method your visual
object will not update but your arraycollection will.

How can I use more than one Data Provider in my web Apps

I am trying to use two different data provider in my web apps to run two different queries from the same table ,the data provider A is working correctly but when I attempt to run data provider B ,It display an error page ,here is the error message : Exception Details :javax.servlet.ServletEx ception
java.lang.RuntimeException: java.sql.SQLException : Cannot connect .Both dataSourceName and url properties are null.

Hi,
You can use more than one data provider in your application. However if you have defined a dataprovider for a particular table already, and wish to bind a component, select the component and use its context menu to Bind to Data...

The ADO NET Source was unable to process the data. ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.

We developed a SSIS Package to pull the data From Oracle source to Sql Server 2012. Here we used ADO.Net source to pull the records from Source but getting the below error after pulling some 40K records.
[ADO NET Source [2]] Error: The ADO NET Source was unable to process the data. ORA-64203: Destination buffer too small to hold CLOB data after character set conversion.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED.
The PrimeOutput method on ADO NET Source returned error code 0xC02090F5.
The component returned a failure code when the pipeline engine called PrimeOutput().
The meaning of the failure code is defined by the component,
but the error is fatal and the pipeline stopped executing.
There may be error messages posted before this with more
information about the failure.
Anything that we can do to fix this?

Hi,
Tried both....
* Having schema type as Nvarchar(max). - Getting the same error.
* Instead of ADO.Net Source used OLEDB Source with driver as " Oracle Provide for OLE DB" Getting error as below.
[OLE DB Source [478]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
[SSIS.Pipeline] Error: SSIS Error Code DTS_E_PRIMEOUTPUTFAILED. The PrimeOutput method on OLE DB Source returned error code 0xC0202009. The component returned a failure
code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing. There may be error messages posted before this with more information about the
failure.
Additional Info:
* Here the Source task is getting failed not the conversion or destination task.
Thanks,
