Data Controls

Hello,
is it possible to create mutiple datacontols in adf application ? OR is it always only one.
thx

Create a second model project with a new ADF BC layer with the new connection to the new database.
Then have your View project mark a dependency on this new model project in the project settings->dependencies

Clear all rows in a Bean Data Control

I am using JDeveloper 11.1.1.6
In my use case I have a screen that interacts with a Bean Data Control I have followed the steps in the following URL to create a Bean Data Control
http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_36/jdtut_11r2_36.html
My screen successfully interacts with the Bean Data Control. This screen lives in a Bounded Task Flow (BTF). I can add rows using a Create Insert binding and can delete Rows as well. Once the user gets all rows into the Bean Data Control that they want inserted to a DB table, I can iterate through the Bean Data Control and post those records to the DB. It is possible for the users to add rows to the Bean Data Control and then link to a brand new screen which is in a different BTF which leaves rows in the Bean Data Control. Now the user goes back to the original screen. Upon returning, I want to empty (clear all rows) for the Bean Data Control so that they have a fresh start. Could you please provide guidance on what I might need to do to be able to clear a Bean Data Control when entering a BTF

Hi,
You can create a method to clear your Bean Data Control and call it with an invokeAction with property refresh="ifNeeded" and refreshCondition="#{pageFlowScope.isTimeToClearAll}", so pageFlowScope.isTimeToClearAll must be true only when you need to clear the BDC.

Not able to drag new data control to my jsf

hi am not able to drag Queriable Attributes into the new query.jsf page and abl to Create it as a Query > ADF Query Panel.
this is what i have done
1.In the Application Navigator locate the adfc-config file under the Page Flows node in the ViewController project. Double-click it to open it in the editor. This is where you are going to define the application's navigation.
2.Drag the DeptEmpPage.jsf file from the Application Navigator into the empty adfc-config diagram.
3.From the Component Palette drag and drop a View component into the adf-config diagram, and rename it query. This represents the new JSF page that you are about to create.
4.From the Component Palette select Control Flow Case and then click on the DeptEmpPage and drag a line to the query page.
Name this line goQuery.
5.From the Component Palette choose another Control Flow Case and then create an opposite flow from the query page to the DeptEmpPage. Name this flow back.
6.Double-click the query view in the diagram to create the new page. In the Create JSF Page dialog accept the default Facelets radio button, and with the Quick Start Layout radio button selected, click Browse.
7.In the Component Gallery, retain the default One Column category, type and layout, but check the Apply Themes checkbox in the Options pane.
Click OK and OK again to create the page.
8.To add the employees search functionality to the page, open the Data Controls accordion, and locate EmpDetails1. (If you do not see it click the Refresh button).
am not able to Select All Queriable Attributes and drag it into the new query.jsf page. Create it as a Query > ADF Query Panel.

I can not find (see) the Data Control Accordion

Hello all,
I cannot find (see) the Data Control Accordion, I just installed the Jdeveloper 11g (Oracle JDeveloper 11g (11.1.1.2.0) - November 2009) from this link http://www.oracle.com/technology/software/products/jdev/htdocs/soft11.html
I started a new ADF BC application, but I cannot find the data control accordion to drag and drop the components I created in the application model. Is there anything I must do after installation (post installation), is there any libraries need to be installed? Please, I need a help to create my application, I’m totally stuck, many thanks for any help.
Kind regards,
Nabil

Many thanks for your reply, kindly find attached screenshots for the two installation of Jdeveloper 11g I have (release 1 & 2), it shows clearly that the “Data Control” is available for release 1, but not available for release 2, even we are talking about the same application!

Not able to Control the Data Control

Hi, I have a bar chart which is bound to datacontrol through one iterator and one access iterator, and is placed on one splitter. Now on moving splitter and resizing the chart datacontrol re-fetches the data from the server. Why ? Cant it just re-size the chart without any connection with server. Also, i tried putting refreshCondition, and as it get calls two times everytime (one for JSF and another for ADF) and set refreshCondtion to false after second call. In that case i got no data. Also i tried refresh Ifneeded in both interators/accessIterator, still No Data. Is there any way i just execute data control only one time and henceforth can avoid its execution ?

Hi Shay,
PageDef Entries :
<accessorIterator MasterBinding="Query1Iterator" Binds="Query" RangeSize="-1" DataControl="Query1" BeanClass="testing.test.datacontrol.definition.Query1.Query" id="QueryIterator" *RefreshCondition="#{pageFlowScope.myEditor.refreshNeeded}"* xmlns="http://xmlns.oracle.com/adfm/uimodel"/>
<iterator Binds="root" DataControl="Query1" id="Query1Iterator" RangeSize="-1" xmlns="http://xmlns.oracle.com/adfm/uimodel"/>
<graph IterBinding="Query1Iterator" id="Query6" xmlns="http://xmlns.oracle.com/adfm/dvt" type="BAR_VERT_CLUST" ChangeEventPolicy="none">
This was the RefreshCondition i was talking about, but after putting this i am not getting any data. And removing this condition will invoke the datacontrol each time i move the splitter. I want to be it like when i order to refresh then only it should execute.
Everytime execution till the server unnecessary makes my application very slow, and i want to be as faster than we see charts in other technologies.
Any help would be appreciated.
Thanks-
Mangal

Refresh the object associated with a Row in a Data Control?

I am using EclipseLink & have an issue with multiple updates of the same Row. During an update, a new instance of the entity is returned by the update method. The instance bound to the Row is not updated with this new version and subsequent updates fail with an optimistic locking exception since the entityVersion hasn't been updated.
Question: Is it possible to refresh the instance associated with a data control Row? I can remove rows, create rows, but it is not apparent to me how to update a row. I am trying to avoid doing a full retrieve on the bound iterator.

Hi!
The issue here is, by my opinion, a gap between ADFm and EJB 3.0 in use-cases with large data sets. If you search this forum, you may find related thread by Pedja about problem of feasible "scrollable" af:table with large number of entities in EJB finder result list. Unfortunately, the ADFm "paged" fetching is in mismatch with EJB support for "paged" (or scrollable) results lists. The all results of EJB finder method are retrieved from data source, stored in memory (thus breaking the heap) and transferred to ADF datacontrol. Then, and only then, ADFm paged fetching and caching mechanisms are employed – but they are just cosmetics as the main data set is permanently stored in memory as List<?>. The workaround is, as Pedja discovered, to write completely proprietary TableCollectionModel which completely evades ADFm and is implemented by set of EJB Session methods for paged acces to datasource through TopLink and native database queries (enabling retrieval of particular range of rows instead a complete result set). Of course, this is very complex coding experience and I find it a not acceptable for efficient development of modern applications on ADF + EJB stack, especially as it brakes a technology independence promoted by EJB and EclipseLink and other standards-based technologies (as you have to use database-specific native query implementation for paged /scrollable access!).
What I want to say is that I have feeling that ADF support for EJB is not complete in full extend and that ADFm is still much better suited for BCs then for EJBs. I hope that this will be solved in future as this issue may pose a significant issue on application development in enterprise-level area where it is supposed that we are dealing with BROWSING also a large data sets.
Yes, I emphasize a BROWSING as I strongly oppose a dogmatic approach that SEARCHING is a solution for every use-case. From theory of information, the system SHOULD NOT limit the user in accessing ALL information (based on access rights, of course). So the idea that SEARCH forms should be used to bridge a architectural gap between a ADFm and EJB is not acceptable, as the search MAY limit the user in acquiring the information he (or she) is not able to describe in adequate manner based on search criteria offered by the developer. So, the developer may be responsible for misinformation of user, by limiting his access to information, jus for technology limitations of ADFm which forces a development of purely SEARCH-based functionalities.
I hope that development team would appreciate and consider this remarks, and invest effort in closing (not bridging!) the gap between ADFm and EJB.

Bind an inputFile value to a data control methods parameter

Hello I am trying to create a InputFile (ADF Faces) which is linked to a data control method. The method reads a specified file and returns the content which is then displayed in table form.
 
I have a filereader Class with the following method:
public List<FileInQuestion> returnFileContents(String fileName)
 
I have created a data control based on this Class. From the JSF page, under the data control palette I can drag on may parameter 'FileName' (as input text) and my method (as command button) and finally the return type 'FileInQuestion' (as read only table). This all works fine and when I type a filename in and hit the button it displays the contents in a table.
 
Now the problem is that I want to base the input parameter on the value of the InputFile component. But when I drag and drop the 'fileName' parameter onto the canvas, it doesn't give me the option to create as an input file!
 
Please could someone tell me how I manually link (bind) the inputFile component to the 'fileName' parameter?
 
Sorry if a bit long winded!!
 
Thanks Dan

Thanks Frank but I need to get at the text value returned from the inputfile component. I did what you said with the following results:
 
I started with a inputtext field, command button and read only table. When I entered a value (in this case 'C:\data\contacts.txt' ) into the inputtext field and hit the command button the table displayed the expected results (for logic please see my 1st post).
 
I then convert the inputtext component to a inputfile component in the way you suggested. I now rerun the application, browse to the same file and hit the command button, and then nothing!! no results.
 
I'm I missing something here?
 
Thanks

Need to Set Current Row when Using Built-in Data Control Delete Operation?

I have an af:table bound to a ViewObject (VO) collection (no Entity Object) - within each row, I include a column that contains a 'Remove' command button so the user can remove the row. I add the command button by dragging/dropping the built-in delete operation from the VO on the Data Control Palette. When I use this as is (no changes), the Remove button always deletes the first row in the collection, not the selected row. Do I need to add code to set the current row, and if so can someone please provide an example and specify where I need to add? thanks.
------ .jspx af:table with command button to remove each row ------
<af:table value="#{bindings.ListView1.collectionModel}" var="row"
rows="#{bindings.ListView1.rangeSize}"
first="#{bindings.ListView1.rangeStart}"
// note: I don't have any code added for selectedRow or makeCurrent - assuming this is built-in?
selectionState="#{bindings.ListView1.collectionModel.selectedRow}"
selectionListener="#{bindings.ListView1.collectionModel.makeCurrent}">
<af:column>
<af:commandButton actionListener="#{bindings.Delete.execute}"
text="Remove"
disabled="#{!bindings.Delete.enabled}"/>
</af:column>
---------- corresponding pagedef file ------------
<bindings>.....
<action id="Delete" IterBinding="ListView1Iterator"
InstanceName="SrchDataControl.ListView1"
DataControl="SrchDataControl" RequiresUpdateModel="false"
Action="30"/>
</bindings>
Note: I also tried solution posted on following thread, but again, only first row is deleted, not the selected row?: Delete and Commit

I just want to delete (or remove) it from the VO. Data for this VO is not on the database.
The function is doing what I want it to do (delete from the VO), its just always deleting the first row, versus the selected row. I select the command button next on a column next to an item further down in the list and it deletes the first row. The problem is setting the selected row to be removed - I thought setting the current row would be taken care of by the SelectListener?
selectionState="#{bindings.MyIspListView1.collectionModel.selectedRow}"
selectionListener="#{bindings.MyIspListView1.collectionModel.makeCurrent}"

Unable to find Web Service Data Control in Menu

Hi
I am trying to call a web service from ADF. For that, I want to create a web service data control
As I understand, if I right click on the Model project, I should see the Web Service Data control under Business Tier > Web Services. (as shown in Sec 2.1 of -- http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html#WsProxyPojoControl)
However, I am not able to find this entry in there.
I have tried the following things:
I have tried with Jdev 10.1.3.5, 10.1.3.4 and 10.1.3.1
I have tried selecting all the technology templates available for creating applications
- No Template
- Web Application [ JSF, EJB, Toplink]
- Web Application [ JSF, ADF]
- Web Application [ JSF, EJB
- Web Application [ JSF, Struts,ADF] ......and everthing else...
I still cant see the web service proxy.
I next opened the Sample ADFToystore application, and I could see the Web service Data control there !....that means my jdev is not faulty...something else is missing.
So I tried to see what all libraries are selected.... I saw that a library named 'Web Service Data Control' is there in the project, which is not there in the model project of applications I created. So I added this library to the project but still it did not work..
Next I added ALL libraries that I could see in the libraries section of Project Properties....still no luck
I am sure I am missing something basic. Can anybody please help.

Web service proxy and data control are not working properly

Hi,
I am working on jDeveloper 11.1.1.6
I have a SOA web service which requires 3 inputs and return with a set of data.
When I tried testing that web service in soapUI it is working perfect. But when I have created a web service proxy in my application and trying to test it from class (*******_ptClient) main method everytime it is replying with the output null
Also When I am requesting from the main method SOA is getting proper input (which I am providing in the main method) and SOA is returning proper output I have checked the SOA instance in em. So there is no problem in SOA side.
After that I have created web service data control and tested in that case also it is not showing any result.
What could be the problem ?
Please help.
Thanks
--NavinK

Hi Shay Shmeltzer,
Thanks for the reply.
I tried in HTTP Analyzer in JDeveloper and there also it is not working. My concern is :-
There are many other web services deployed on the same SOA server in same partition and they are working fine in HTTP analyzer and I am able to create and use the web service proxy as well. So as per my understanding there is nothing like network issues between SOA server and jDeveloper.
1 more thing When I am creating the proxy for this web service and requesting from the proxy's main method SOA is getting proper input (which I am providing in the main method) and SOA is returning proper output I have checked the SOA instance in em. So there is no problem in SOA side. The problem is jDeveloper is not able to get back that response which SOA is returning.
Please Help.

Not able to access SOAP web service data control from adf mobile

Hi,
I am trying to call web services from adf mobile..
I have created data control from external web service and it is perfectlly working on web browser..
But why it is showing an error on emulator??
Is there any .jar file missing in adf mobile so that it is not supporting a web service?
Or is there any other problem? Emulator is connected to network and I am able to run WSDL in emulator's browser..
Please help me to solve this issue..
Thanks,
Laxmi

Emulator is connected to network and I am able to run WSDL in emulator's browser..
Connecting to WSDL in the browser is not the same as connecting to WSDL in an application.

Using WebCenter Spaces Web Service API through JDeveloper's Data Control

Hi,
I'm trying to access WebCenter Spaces Web Service API (located at http://host:port/webcenter/SpacesWebService)
using JDeveloper's Web Center Data Control.
I created a data control in my portal project using JDeveloper's Web Service Data Control wizard.
I also created and configured key stores (jps-config.xml) at both sides (spaces server and my portal client).
How I created a data control:
* First I entered the name and the URL (http://host:port/webcenter/SpacesWebService?WSDL)
* Then I entered HTTP basic authentication details (user name and password)
* After that I drag-and-drop the getGroupSpaces() method from the data control to a .jspx page as a ADF read-only table.
* Then ran my portal project and navigated to this .jspx page and it worked. List of group spaces appeared well on that page.
The problem is that I got only public group spaces and group spaces created by the user I entered on HTTP basic authentication details.
I makes no sense to enter some static user details in a web service client (or a data control).
So the question is; can I use identity propagation to get only group spaces created by the same user which I logged in my portal?

Hi,
You generally get NameError when you are executing the createCred/updateCred from a incorrect location. Are you using the wlst from oracle_common\common\bin?
Also, In your steps I don't see what you did to populate the walllet at JDeveloper end after your updateCred failed. This is a required step. Use the wlst from the location emntioned above and you should be able to proceed.

How to use multiple data controls in a single JSF page

Hi,
I am using Essbase Data Control to in my project to get Essbase Cube data into ADF table/Pivot Table.
Suppose if [Item] dimension has this hierarchy [category] -> [Segment] -> [Brand] -> - [Item]
I need to display Category in one column and Segment in the next Column and [Brand] in the another column.
Different types of Category, Segment and Brands should display as table data(data values).
Using MDX query I can not print [Item] hierarchy in different columns..so I am planning to use multiple data controls.
Could any body help me to get the solution.

Hi,
sounds like you want to try the Pivot table
http://download.oracle.com/docs/cd/E21764_01/apirefs.1111/e12418/tagdoc/dvt_pivotTable.html
I don't think that multiple Data Controls is the solution to the problem

How Can I use a Variable in Data Controls query. Frank Kindly check...

Hii,
I am using JDeveloper 11g ADF BC.
My Requirement is that I hv a login screen which is taken from [http://blogs.oracle.com/shay/simpleJSFDBlogin.zip].
I hv attached BC in this application. I want to use the login usercode in the next pages after login screen. Next screen contains 3 list items which will be populating based on the user. So I created <af:selectOneChoice> using the BC( Just drag & dropped the column into the page from the data controls). But in the data control i want to use this usercode for passing the condition. Now Data is coming without any condition.
So How can I use the usercode in the Data controls query.

Hi,
I didn't look at the example, but if you want to secure your application then you should use container managed security. Read this .
Anyway, you could add this before return "good"; in your login_action()
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put("username", user);Then, you can access this from anywhere in the application by using #{sessionScope.username}.

How to get value in data control at run time based on bind variable in VO

Hi,
we are capturing the value of customer id at run time. we are associating the captured value of customer id to bind variable of the view object.
View object is returning the data of that customer id, this view object is part of the application module ,this application module is exposed as data control,so than we have drag and drop this view object response on the
page from data control.
How ever after assigning the customer id to bind variable but still it is not showing on jsf page,even we refreshed the data control manually with the help of java code so kindly provide some solution for it.

Hi,
If i got your post correctly,you can filter your VO using defining view criteria see following samples
