How to bind several Rowrepeaters at runtime ?

Hi Experts,
I have a context node with the following structure:
Tests (coordinality: 0..n, singletone: true)
Results (coordinality: 0..n, singletone: false)
I need to bind Results node of each TestsElement to its own RowRepeater at runtime.
I do not know the quantity of Tests elements because each time it is different.
I thought that the only solution is to create at runtime needed quantity of RowRepeaters and simply bind their datasources to
Tests.Results context path. But it does not work and simple shows me all RowRepeaters with the last Test element Results node data.
Therefore i think that the only solution is to create all RowRepeaters and Results nodes for each one of them at runtime and bind them at runtime.
The structure of the context will look like this:
Tests (coordinality: 0..n, singletone: true)
Results0 (coordinality: 0..n, singletone: true)
Resultsn (coordinality: 0..n, singletone: true)
I think it will work , but is there any other simpler solution for the problem ?

Hi
Since, during design time you have no idea how many element will be there at user Interface, so only solution is in WebDynpro
is implement the code at WdDoModifyView at runtime based on the database/data source condition it will automatically render the those number of element .
Now there are too many solution to achieve this ..[best with code help is here|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/47ce9b90-0201-0010-59b5-f70826824eee?quicklink=index&overridelayout=true] and [Dynamic UI Generation |http://wiki.sdn.sap.com/wiki/display/WDJava/DynamicUIGeneration]
(here UI context are diffent but logic is same for all the version 7.0 /7.1).

I think what darnold was trying to say....
Those very clever people who come up with insights on human behaviour have studied how many records a user can work with effectively.
It turns out that they can't see thousands of records at once.
Their advice is that one presents a maximum of 200-300 records at a time.
What with maybe 40 fitting on a screen at a time. Few people like spending 20 minutes scrolling through a stack of data they're not interested in to find the one record they're after.
Personally, I would use a treeview, set of combos or some such so the user can select what subset they are interested in and present just that.
Anyhow.
If you have a viewmodel which exposes an observable collection<t> as a public property you can bind the itemssource of a datagrid to that.
Although UI controls have thread affinity, the objects in such a collection do not.
That means you can use another thread to go get your data, add it to the observable collection, the fact it's an observable collection tells the view as records are added and it will show them. The ui will remain responsive.
You can do this using skip and take to read a couple hundred records at a time and add those, pause and repeat for the next couple hundred records. Use linq - skip and take.

How to Bind a Combo Box so that it retrieves and display content corresponding to the Id in a link table and populates itself with the data in the main table?

I am developing a desktop application in Wpf using MVVM and Entity Frameworks. I have the following tables:
1. Party (PartyId, Name)
2. Case (CaseId, CaseNo)
3. Petitioner (CaseId, PartyId) ............. Link Table
I am completely new to .Net and to begin with I download Microsoft's sample application and
following the pattern I have been successful in creating several tabs. The problem started only when I wanted to implement many-to-many relationship. The sample application has not covered the scenario where there can be a any-to-many relationship. However
with the help of MSDN forum I came to know about a link table and managed to solve entity framework issues pertaining to many-to-many relationship. Here is the screenshot of my application to show you what I have achieved so far.
And now the problem I want the forum to address is how to bind a combo box so that it retrieves Party.Name for the corresponding PartyId in the Link Table and also I want to populate it with Party.Name so that
users can choose one from the dropdown list to add or edit the petitioner.

Hello Barry,
Thanks a lot for responding to my query. As I am completely new to .Net and following the pattern of Microsoft's Employee Tracker sample it seems difficult to clearly understand the concept and implement it in a scenario which is different than what is in
the sample available at the link you supplied.
To get the idea of the thing here is my code behind of a view vBoxPetitioner:
<UserControl x:Class="CCIS.View.Case.vBoxPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:v="clr-namespace:CCIS.View.Case"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
d:DesignWidth="300"
d:DesignHeight="200">
<UserControl.Resources>
<DataTemplate DataType="{x:Type vm:vmPetitioner}">
<v:vPetitioner Margin="0,2,0,0" />
</DataTemplate>
</UserControl.Resources>
<Grid>
<HeaderedContentControl>
<HeaderedContentControl.Header>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right">
<TextBlock Margin="2">
<Hyperlink Command="{Binding Path=AddPetitionerCommand}">Add Petitioner</Hyperlink>
| <Hyperlink Command="{Binding Path=DeletePetitionerCommand}">Delete</Hyperlink>
</TextBlock>
</StackPanel>
</HeaderedContentControl.Header>
<ListBox BorderThickness="0" SelectedItem="{Binding Path=CurrentPetitioner, Mode=TwoWay}" ItemsSource="{Binding Path=tblParties}" />
</HeaderedContentControl>
</Grid>
</UserControl>
This part is working fine as it loads another view that is vPetioner perfectly in the manner I want it to be.
Here is the code of vmPetitioner, a ViewModel:
Imports Microsoft.VisualBasic
Imports System.Collections.ObjectModel
Imports System
Imports CCIS.Model.Party
Namespace CCIS.ViewModel.Case
''' <summary>
''' ViewModel of an individual Email
''' </summary>
Public Class vmPetitioner
Inherits vmParty
''' <summary>
''' The Email object backing this ViewModel
''' </summary>
Private petitioner As tblParty
''' <summary>
''' Initializes a new instance of the EmailViewModel class.
''' </summary>
''' <param name="detail">The underlying Email this ViewModel is to be based on</param>
Public Sub New(ByVal detail As tblParty)
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Me.petitioner = detail
End Sub
''' <summary>
''' Gets the underlying Email this ViewModel is based on
''' </summary>
Public Overrides ReadOnly Property Model() As tblParty
Get
Return Me.petitioner
End Get
End Property
''' <summary>
''' Gets or sets the actual email address
''' </summary>
Public Property fldPartyId() As String
Get
Return Me.petitioner.fldPartyId
End Get
Set(ByVal value As String)
Me.petitioner.fldPartyId = value
Me.OnPropertyChanged("fldPartyId")
End Set
End Property
End Class
End Namespace
And below is the ViewMode vmParty which vmPetitioner Inherits:
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
Imports CCIS.Model.Case
Imports CCIS.Model.Party
Imports CCIS.ViewModel.Helpers
Namespace CCIS.ViewModel.Case
''' <summary>
''' Common functionality for ViewModels of an individual ContactDetail
''' </summary>
Public MustInherit Class vmParty
Inherits ViewModelBase
''' <summary>
''' Gets the underlying ContactDetail this ViewModel is based on
''' </summary>
Public MustOverride ReadOnly Property Model() As tblParty
'''' <summary>
'''' Gets the underlying ContactDetail this ViewModel is based on
'''' </summary>
'Public MustOverride ReadOnly Property Model() As tblAdvocate
''' <summary>
''' Gets or sets the name of this department
''' </summary>
Public Property fldName() As String
Get
Return Me.Model.fldName
End Get
Set(ByVal value As String)
Me.Model.fldName = value
Me.OnPropertyChanged("fldName")
End Set
End Property
''' <summary>
''' Constructs a view model to represent the supplied ContactDetail
''' </summary>
''' <param name="detail">The detail to build a ViewModel for</param>
''' <returns>The constructed ViewModel, null if one can't be built</returns>
Public Shared Function BuildViewModel(ByVal detail As tblParty) As vmParty
If detail Is Nothing Then
Throw New ArgumentNullException("detail")
End If
Dim e As tblParty = TryCast(detail, tblParty)
If e IsNot Nothing Then
Return New vmPetitioner(e)
End If
Return Nothing
End Function
End Class
End Namespace
And final the code behind of the view vPetitioner:
<UserControl x:Class="CCIS.View.Case.vPetitioner"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:CCIS.ViewModel.Case"
mc:Ignorable="d"
Width="300">
<UserControl.Resources>
<ResourceDictionary Source=".\CompactFormStyles.xaml" />
</UserControl.Resources>
<Grid>
<Border Style="{StaticResource DetailBorder}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Petitioner:" />
<ComboBox Grid.Column="1" Width="240" SelectedValuePath="." SelectedItem="{Binding Path=tblParty}" ItemsSource="{Binding Path=PetitionerLookup}" DisplayMemberPath="fldName" />
</Grid>
</Border>
</Grid>
</UserControl>
The problem, presumably, seems to be is that the binding path "PetitionerLookup" of the ItemSource of the Combo box in the view vPetitioner exists in a different ViewModel vmCase which serves as an ObservableCollection for MainViewModel. Therefore,
what I need to Know is how to route the binding path if it exists in a different ViewModel?
Sir, I look forward to your early reply bringing a workable solution to the problem I face.
Warm Regards,

How to bind value to lov based on the output from other lov

Read the dev guide LOV section, it should give you details about this implementation.

RE : How to bind to two interfaces

Gabriel,
You can advertise an environment on two ip addresses
by using multiple IP addresses instead of one in
FORTE_NS_ADDRESS. Specify the IP addresses separated by semicolon
setenv FORTE_NS_ADDRESS ip1:5000;ip2:5010;ip3:5012
You will also have to define FORTE_LOCATIONS to point
to these IP addresses so that Forte runtime knows where
to find the environment and services. In this case you
will always use the socket number 0 to allow Forte to
pick any available socket.

Subject: How to bind to two interfaces
Hi!
On one of our Solaris servers we are facing the problem that we have
two
network interface cards in it.
And we would like to access Forte on it through both cards. (avoid
unnecessary network traffic)
As far as I understand Forte needs a fix IP address to bind to (thus
bound to one card).
I tried to use 0.0.0.0 as a jolly-joker for all cards, but failed.
Has anybody an idea? Or is it a restriction?
If so, does Forte plan to improve the product in this way?

Hello
I assume you want to create multiple instance of your class.
Assuming that you class is NOT a singleton then simply repeat the CREATE OBJECT statement as many times as you need.
TYPES: begin of ty_s_class.

How can I create a Forms9i Runtime for client distribution

Currently we have an application developed in Forms 5.0.6.8.0 our Database has been upgraded to 9i DB. The application is working fine with this combination but we want to upgrade Forms in order to get Oracle Support. We just get the Developer Suite 9i package and we're trying to test our application with this software.
How can I create the client runtime for Forms 9i?
My application will work with Win 95 and 98?
Thanks.

Oracle9i Forms is web-only. Forms 6i is the last release of Forms to have client/server and character mode.
You can test Forms from the Builder by installing iDS. To deploy Forms using iAS follow the documentation. It's all there in the deployment guide.
iAS and Forms doco can be found on OTN.

How to structure several scenes (in symbols) on the main stage timeline

Hi,
I'm new to edge animate but have a Flash background and I'm working in Edge Animate on a game which is structured in several scenes. Each scene I did put in a symbol. Now I wonder how to build the main timeline or the "story - controller" so to speak. I have all the scenes but I do not know how to connect them.
In Flash it was possible to add keyframes of scenes one after another (like stairs) and jump forward or backward if needed to load the movie clips. In Edge Animate all scenes (or symbols) are in place from the beginning of the timeline and I cannot move the symbol to a later keyframe. Of course I can move animations in the timeline. The only way I think is to hide the symbols first and make them visible if needed. But this does not seem to be the right way and I don't understand the concept of structuring complex animations yet.
I would like to know how to structure several scenes in Edge Animate properly. Something like a scene loader or unloader would be useful. Highly appriciate any hints to a solution.
Thank you,
JP

You can also use edgecommons to load edge composition into another edge composition.
Thank you to your tipp so I try to organize my scenes into compositions. I can successfully load a composition (scene2) into the main container :
EC.loadComposition("scene2.html", sym.getSymbol("mainContainer"));
Now I'm facing another situation. At the end of the loaded composition scene2 is a "Next Scene" button suppose to load scene3.html composition into the main container. "Next Scene" is a nested button inside the loaded composition screen2 symbol. How do I load the next compostion from the current one? This code for On Click of course does not work:
EC.loadComposition("scene3.html", sym.getSymbol("mainContainer"));
I think the refer to the mainContainer is wrong. Is it just a targeting issue or is it the wrong approach in general?

How to bind a UI element to the context

Hi Experts,
           I have a problem binding UI element to the context. In my code i have to create TabStrips dynamically and under this tabstrip number of UI elements would be there. For this i have a code like this..
IWDTransparentContainer theActionContainer =(IWDTransparentContainer)view.getElement("RootUIElementContainer");
     IWDTabStrip ts = (IWDTabStrip) view.createElement(IWDTabStrip.class,"TabStrip");
          IWDTab tab1 = (IWDTab) view.createElement(IWDTab.class,"Tab1");
          IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
          IWDCaption header1 = (IWDCaption) view.createElement(IWDCaption.class,"Header1");
          header1.setText("Tab1");
          tab1.setContent(in);
          ts.addTab(tab1);
          IWDTab tab2 = (IWDTab) view.createElement(IWDTab.class,"Tab2");
          IWDInputField in2 = (IWDInputField) view.createElement(IWDInputField.class,"in2");
          IWDCaption header2 = (IWDCaption) view.createElement(IWDCaption.class,"Header2");
          header2.setText("Tab2");
          tab2.setHeader(header2);
          ts.addTab(tab2);
          theActionContainer.addChild(ts);
<b>when i run this code it is giving following exceptions..</b>
The initial exception that caused the request to fail, was:

From these exceptions what i understood is, i need to bind these UI elements to context.
   Can any body tell me how to bind a UI element to the context if I understood the exceptions correct..
Thanks in Advance,
Murthy.

HI,
lets say Ctx is your context attribute,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getAttribute("Ctx");
then , as per your code,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
<b>in.bindValue(attrInfo);</b>
if your contex attribute is child of some other node then do like this,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getChildNode("SalesOrder",0)getAttribute("Ctx");
//this is when Ctx is child of node SalesOrder, and we are taking Ctx from its 0th element
then ,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
<b>in.bindValue(attrInfo);</b>
include this in your code ,
let me know if you face any problem
regards

How to bind an aggregated list to a variable in an IN or ANY clause

Hello, and thank you for helping -
I have a process that involves a parameter assertion, the result of which is a string for an IN or ANY clause. I am not able to figure out how to bind the result of the assertion to to executable SQL. The actual business process is long and laborious and, I decided, not worth explaining for the purpose of this forum. I have abstracted the process into some dummy data. The goal is to bind v_any_condition to :a. I could certainly build the SQL without the binding, but I would be very interested to know just the same what I am missing here (I'm sure something simple, or just a basic SQL rules that I have missed).
Thanks!
DECLARE
-- The goal is to bind v_any_condition in an ANY clause
v_any_condition VARCHAR2(30) DEFAULT '4,9,d'; -- the three rows to return from the sample data
-- v_any_condition VARCHAR2(30) DEFAULT DBMS_ASSERT.ENQUOTE_LITERAL('4')||','||
-- DBMS_ASSERT.ENQUOTE_LITERAL('9')||','||
-- DBMS_ASSERT.ENQUOTE_LITERAL('d');
v_sql varchar2(2048);
-- We'll create a simple cursor of VARCHAR2(1) just like DUAL.DUMMY
rc sys_refcursor;
rc_record dual%ROWTYPE;
v_counter NUMBER DEFAULT 0;
BEGIN -- Build the SQL. In this example, we decompose an aggregated string
-- containing the first 16 hex numbers. The result is a simple 16-row table
-- from which we will attempt to return the three rows by binding
-- v_any_condition to ANY in the SQL below.
v_sql := '
SELECT token
FROM ( -- materialize the list
WITH t AS (SELECT ''0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f'' AS txt FROM DUAL)
-- then decompose the list into rows
SELECT REGEXP_SUBSTR (txt, ''[^,]+'', 1, LEVEL) AS token
FROM t
CONNECT BY LEVEL <= LENGTH(REGEXP_REPLACE(txt,''[^,]*''))+1
/* WHERE token = ANY(''4'',''9'',''d'') */ -- hardcoding works
WHERE token = ANY(:a) -- binding does not work; the goal is to get this to work '
OPEN rc FOR v_sql USING v_any_condition; -- when binding, we never even enter the loop
LOOP
v_counter := v_counter + 1;
FETCH rc INTO rc_record;
EXIT WHEN rc%NOTFOUND;
DBMS_OUTPUT.PUT_LINE (v_counter || ': '||rc_record.dummy);
END LOOP;
END;

Superb. Thank you very much.
For anyone who is interested in the solution I chose, here is the revised SQL that accepts a list as a bind variable after casting the list as a table. The "split string" code is below that. (What look like double quotes in the block below are actually consecutive single quotes.)
DECLARE
v_any_condition VARCHAR2(30) DEFAULT '4,9,d';
v_sql varchar2(2048);
rc sys_refcursor;
rc_record dual%ROWTYPE;
v_counter NUMBER DEFAULT 0;
BEGIN
v_sql := '
SELECT token
FROM (
WITH t AS (SELECT ''0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f'' AS txt FROM DUAL)
-- then decompose the list into rows
SELECT REGEXP_SUBSTR (txt, ''[^,]+'', 1, LEVEL) AS token
FROM t
CONNECT BY LEVEL <= LENGTH(REGEXP_REPLACE(txt,''[^,]*''))+1
, TABLE(CAST(XX_SPLIT_STRING(:a,'','') AS XX_SPLIT_TABLE)) cst
WHERE cst.column_value = token'
OPEN rc FOR v_sql USING v_any_condition;
LOOP
v_counter := v_counter + 1;
FETCH rc INTO rc_record;
EXIT WHEN rc%NOTFOUND;
DBMS_OUTPUT.PUT_LINE (v_counter || ': '||rc_record.dummy);
END LOOP;
END;
-- And the main SQL, just for clarity:
SELECT token
FROM (
WITH t AS (SELECT '0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f' AS txt FROM DUAL)
SELECT REGEXP_SUBSTR (txt, '[^,]+', 1, LEVEL) AS token
FROM t
CONNECT BY LEVEL <= LENGTH(REGEXP_REPLACE(txt,'[^,]*'))+1
, TABLE(CAST(XX_SPLIT_STRING('4,9,d',',') AS XX_SPLIT_TABLE)) cst
WHERE cst.column_value = token;
CREATE OR REPLACE FUNCTION XX_SPLIT_STRING (
p_string VARCHAR2
, p_delimiter VARCHAR2 DEFAULT ','
RETURN XX_SPLIT_TABLE PIPELINED
IS
l_idx PLS_INTEGER;
l_string VARCHAR2(32767) := p_string;
l_value VARCHAR2(32767);
BEGIN
LOOP
l_idx := INSTR ( l_string, p_delimiter );
IF l_idx > 0 THEN
pipe ROW ( SUBSTR ( l_string, 1, l_idx - 1 ) );
l_string := SUBSTR ( l_string, l_idx + LENGTH (p_delimiter) );
ELSE
PIPE ROW ( l_string);
EXIT;
END IF;
END LOOP;
RETURN;
END XX_SPLIT_STRING;

How do I deal with a Runtime Error on Adobe Acrobat 9.5?

How do I deal with a Runtime Error on Adobe Acrobat 9.5? The instructions say to contact the support team but I have to pay in order to do so.

What operating system and what is the statement of the error. Typically you would first run a repair on Acrobat from the help menu (or in Windows you can do that from the Control Panel>Add/Remove Programs).
