Help on Adf faces forEach

Hi
I am trying to use <af:forEach tag as below.
<af:forEach var="item" items="${userBean.list}" varStatus="bStatus">
</af:forEach>
public Item[] getList() {
return items;
Class Item {
long id;
String name;
public long getId();
public String getName();
Thanks a lot in advance.

  • Help required building ADF-Swing/ADF-Faces using ADF Business Components

    My question is in regards to how you can go about building a light swing application to an ADF model?
    In particular if I were to say that we were developing a 3-tier project whereby we had a database tier, a series of EJB-ADF façade session beans to the database (middle-tier), and a swing client communicating with the session beans (view-controller tier), how would you go about developing these screens?
    In particular can we develop these screens using ADF-Faces and also ADF-Swing?
    The EJB session façade beans of course are ADF app modules with customised methods. The methods would return back customised DTO objects. These DTO objects are wrappers to row objects ADF would create. This would be mainly due to making these facade beans web service enabled (Oracle state that these methods cannot return oracle.jbo objects if they are to be web service enabled).
    This would be typically deployed to an app server, like Oracle App Server 10G.
    Could you please have a look at this, as I am doing a lot of research into this.
    eg. Taking example from oracle magazine sept/oct 2006
    with slight enhancements
    package oramag.frameworks.example.common;
    import oracle.jbo.ApplicationModule;
    import oramag.frameworks.customdto.EmployeeDTO;
    public interface HRService extends ApplicationModule {
    void deleteCurrentEmpAndCommit();
    EmployeeDTO findEmployee(int employeeId); // new method
    import oramag.frameworks.customdto.EmployeeDTO;
    public class HRServiceImpl extends ApplicationModuleImpl {
    public void deleteCurrentEmpAndCommit() {
    Row empRow = getEmpView().getCurrentRow();
    if (empRow != null) {
    empRow.remove();
    getDBTransaction().commit();
    public EmployeeDTO findEmployee(int employeeId)() {
    EmployeeDTO employeeDTO = null;
    EmployeesImpl employees = getEmployees();
    employees.setNamedWhereClauseParam("EmployeeId", employeeId);
    employees.executeQuery();
    if(employees.hasNext()) {
    EmployeesRowImpl employee = (EmployeesRowImpl)employees.next();
    employeeDTO = new EmployeeDTO(employee);
    return employeeDTO;
    public EmployeesImpl getEmployees() {
    return (EmployeesImpl)findViewObject("Employees");
    Now given the above code snippet, how could you turn this into an ADF-Swing/ADF Faces application so that if a user using the swing application enters an employee id, then the application will execute the query on the app server, the app server in turn returns the results to the client, and the client finally display the results. Typical MVC example.
    Cheers
    Rodney

    The tutorial is for ADF BC used with JavaServer Faces.
    While the tutorial doesn't cover it, we also support drag and drop development for Swing and visual WYSIWYG layout for Swing panels and windows, too. For a very simple example, watch screencast #4 on my blog here:
    http://radio.weblogs.com/0118231/stories/2005/06/24/jdeveloperAdfScreencasts.html
    One thing I have noticed is that when using ADF business components, when the app module returns a custom DTO object like the above example, it returns the data in a element structure according to the data control palette.
    You don't generally ever need to create your own custom DTO's when working with ADF for use by client UI's. The only situation where can be necessary -- until we simplify this in the JDeveloper/ADF 11g release -- is when you desire to expose custom methods that can return sets/arrays of typed row structures through a web service. However, web services are not involved/required in building 3-tier Swing applications.
    When dropping onto a page it does so like a string and doesnt give option to display the data in a read only form etc. Is there anything we need to do, to get the functionality.
    It's more of what you don't need to do :-)
    Just leverage the active data model that the ADF application module provides. You can read more about it in section 4.5 "Understanding the Active Data Model" of the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center at http://www.oracle.com/technology/products/adf/learnadf.html). Your UI's bind to view object instances in the data model, and your UI's are automatically kept up to date without needing to write methods that return data. I short article I wrote that preceeded my writing the ADF Developer Guide content on this topis is here:
    http://radio.weblogs.com/0118231/stories/2006/01/26/theAdfBusinessComponentsActiveDataModel.html
    I know that when dropping a view object you get this functionality. Also was wondering if we were to pass an object of thios type back to the model it might not give us the rich functionality like input forms, like what Oracle provides if we were to drop a enitity view object.
    Just use the active data model and everything becomes totally easy, with no changes required to switch between local or three-tier deployment configurations.
    Trying to do everything with hand-coded DTO beans is really going the hard way.
    Could you help us regarding this?

    I used to get this error time a ago when using MyFaces. It was caused by not getting the page through the Faces Servlet. This time that's not the case. I've got:
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>
    and I load the page this way: http://localhost:8080/MyApp/faces/main.jspx
    Maybe it's because I'm missing some libraries within the war. Next I list the jars I'm incluiding in the archive:
    adf-faces-api.jar
    adf-faces-impl.jar
    adfshare.jar
    commons-beanutils.jar
    commons-collections.jar
    commons-digester.jar
    commons-logging-api.jar
    commons-logging.jar
    jsf-api.jar
    jsf-impl.jar
    jstl.jar
    Any help would really be appreciated.
    Thank you very much.
    Joaquín.

    I suggest that see on JBoss server the list of jndi tree, maybe the entity stay whit another name.
    You can go to server administrator page, login on jboss console and find the jndi list. JBoss bring with a mbean that can show the jndi tree of the server, you can use the JMX console of the JBoss to invoke it.
    Sorry for my poor english

  • ADF FACES: af:forEach and panelGrids

    Hi,
    I can't get code resembling the following to work:
    <h:panelGrid columns="4">
      <af:forEach items="#{bindings.WebCategoriesIterator.collectionModel}"
        var="current">
        <af:panelGroup>
          <af:outputText value="#{current.CatName}" />
          <af:outputText value="#{current.CatDesc}" />
        </af:panelGroup>
      </af:forEach>
    </h:panelGrid>Am I misunderstanding how one of these components works? I know <af:forEach> "only works with ADF Faces components", but I'd been assuming that means that all the components inside it have to be ADF Faces components, not that all the components on the page do. (That is, I'd assumed that the panelGrid was fine.)
    I get a couple of Log4J "Error null" messages on the console when I run this, and the panel grid doesn't seem to render at all. A table built on the same data model works fine.
    Assuming I can't use a forEach inside a panel grid, does anyone have any suggestions? Eventually, there will be images and links in these cells--the idea is to have a n x m grid of images, each linked to a "product" page, much as you might see in most web stores.
    I suppose I could use a large tableLayout with cellFormats and manually check each row in the range in the form bean, setting rowLayout and cellFormat properties to "false" once there aren't any more rows, but this seems hideously ugly for what should be a fairly simple widget.

  • ADF FACES: jdeveloper hangs on opening a .jspx file

    I may not have had this file open since updating to EA13, but I'm not positive. Upon trying to open the file (code below), jdeveloper hangs. It sucks down roughly 50% of the CPU and the memory footprint slowly grows (about 3 MB per minute). As of now, I've tried restarting jdeveloper and then opening the file, but the behavior is the same. I have let it run for nearly 15 minutes and it is still hung (to the point that the display is not redrawn when a window, such as the task manager, is closed after obscuring part of the jdeveloper window).

    Helo there,
    I am having exactly the same problem, everytime I include af:forEach tag inside the af:selectOneChoice for example, preview of JSP is not shown and whole developer hangs, in task manager I can see 100% CPU occupation by JDeveloper.
    But the code itself is ok, if I run the page while editor is in Source mode Page is properly shown in browser, but when I change editor mode to Design it hangs.
    I am using Faces EA17 and JDeveloper 10.1.3
    Does anybody else face the same issue?

  • ADF Faces useWindow attribute

    I am trying to open a Dialog window using an af:CommandLink. It is not opening a new window, only navigating to the page as normal. Is there anything obvious I am doing wrong? I have also seen this syntax
    useDialog="true"
    The IDE is rejecting this as not part of the tld. It may have been part of an earlier version of ADF Faces?
    Here is the script from the page
    <af:table   var="row"
                value="#{accountBacking.accounts}"
                rows="5"
                banding="row"
                styleClass="table.sample"
                binding="#{accountBacking.table}"
                >
    .......Trimmed for relevance.........
        <af:column formatType="icon">
            <f:facet name="header">
                <af:outputText value="Edit"/>
            </f:facet>                      
            <af:commandLink useWindow="true"
                            action="#{accountBacking.editAccountAction}"
                            partialSubmit="true">
                <af:objectImage source="/images/edit-blue.gif"/>
            </af:commandLink>
        </af:column>
    .......Trimmed for relevance.........
    </af:Table>

    I figured it out. In older examples where useDialog was used, the return value from the action was "process:something". This was also defined as a navigation rule in faces-config.xml
    I found an example from oracle that uses the useWindow attribute. Instead of "process:something" it should be "dialog:something"
    Here is the example
    http://www.oracle.com/webapps/online-help/jdeveloper/10.1.3/state/content/navId.4/navSetId._/vtTopicFile.jsf_apps%7Cadfcreate%7Caf_acommandanddialog~html/

  • ADF Faces  IF statement available within the  page?

    I am making a page using ADF Faces.
    I want to create an IF statement in a page that will display some markup on one condition and on another display some other markup.
    For example, I am using an iterator to build a table. I would like to have the background color of the row alternate based on the iterator count % 2 ( also how can I get the count of the iterator).
    Also, I would want to make the text color highlight based on some condition such as is foo==bar make the text red etc.
    Anyone know how to do this simple simple task in ADF Faces?
    **Note the if from JSF core is not available in Jdeveloper for whatever reason. Any help would be appreciated.
    Also, I don't want to just set some property of some element based on a condition with EL.
    Lets say there is a whole section of the page that I only want to show is a condition is true. Is this impossible in ADF Faces? Is there something fundamental I am missing about this framework?
    Edited by: user2809800 on Dec 6, 2010 12:49 PM

    For conditional rendering of group of fragments, you can use switcher component.
    See the sample for switcher here: http://jdevadf.oracle.com/adf-richclient-demo/faces/components/switcher.jspx
    Code:
    <af:switcher id="s1" defaultFacet="#{<CONDITION> == 'true' ? 'two' : 'three'}">
    <f:facet name="two">
    <af:outputText id="ot2" value="Two"/>
    </f:facet>
    <f:facet name="three">
    <af:outputText id="ot3" value="Three"/>
    </f:facet>
    </af:switcher>
    For changing the text color based on the condition, you could use the EL expression in InlineStyle (it is a simple case) Otherwise, you can use skinning to change the same.
    Sample:
    <af:outputText id="ot4" value="#{bindings.FirstName.inputValue}"
    inlineStyle="#{bindings.FirstName.inputValue == 'Steven' ? 'color:red' : null}"/>

  • MyFaces not rendering, ADF faces IS rendering

    I'm installing my app on the websphere application server, Version 6.1 After having issues of both adf and myfaces not working, I came accross this link which helped me somewhat. http://wiki.apache.org/myfaces/Websphere_Installation .
    By "not working" I mean that my jsp would have <h:commandLink>'s and <af:commandButton/> however the html was never actually generated. (You could view the pages source and the resulting html page was blank).
    After following those instructions, ADF components are correctly rendered, and the html works. However, I can not use any <h:> or <h:> components.
    Keep in mind, every single part of this used to work while using Tomcat (I think it was 5.5, not 6).

  • Jdeveloper 10.1.3.3.0.4157  ADF faces  Do not render in visual editor

    The ADF Faces Components do not display in the visual editor
    The code window shows all these features present and properly coded
    These components are from the ADF Faces Core page of the Component Pallete
    I tried quitting and re-starting jdeveloper , to no avail
    I placed an af:panelPage on h:form and typed in a title-(blank visual editor)
    I placed an ObjectImage and placed it on the branding facet
    I bound a logo.image to this component - (still blank visual editor)
    All of this insertions into the form are recorded in the code window
    but do not appear in the Visual Designer.
    Using jdeveloper10.1.2.2.0.4157
    JDK 1.5.0_15
    windows xp professional
    The example project is from the Book:
    Oracle JDeveloper 10g for Forms & PL/SQL Developers

    Thank you for your reply.
    On jdevelper startup I get the following message:
    ResourceManager : unable to find resource 'VM_global_library.vm' in any resource loader.
    For no Reason at all,(except for starting and shutting down jdeveloper)
    I am now getting a view: An Outline with tags in order , but not a simulation
    of a web page???But a correct development structure with tags/values identified.
    there are many libraries in the properties page , I'm a newbie so wouldn't
    know if any of these would help?

    Just like the one in adf-faces-10_1_3_0_4.zip.
    I think it's the best tutorial to study adf faces 11!
    Anyone can help? Thank you!

  • Portlets with ADF faces does not work

    Hello
    I am trying to portlize an hello world ADF application but am unable to do so because of the situation describe below. I have tried all the options given on this post but nothing seems to resolve the issue.
    I have followed the instructions of portelizing at http://download-east.oracle.com/otndocs/tech/webcenter/files/owcs_10132_bridge_viewlet.html
    A simple portlets without AFD works fine in oc4h or webcenter or jboss, but when I include ADF in the project then none of the application server or the container works
    I am using jdeveloper 10.1.3.2.0 and the embedded webcenter oc4j for this test
    I have two projects
    1) ui where the ADF appplication is and
    2) test1 where the producer is registered and is tested
    In ui I have a simple jsp page untitled1.jsp with just one adf component (ADF Command Link)
    Here is the source of untitled1.jsp

    Then I tried to deploy the test1.jsp as a WAR file in the webcenter OC4J and tried this URL
    http://localhost:6688/AdfFacesDemoTest1/test1.jsp
    but it gave me this error
    500 Internal Server Error
    Servlet error: An exception occurred. The current application deployment descriptors do not allow for including it in this response. Please consult the application log for details.
    When I tried this URL I got a diffrent error. Googling this did not help at all

    Hello dvohra,
    Thanks for the reply but I have done everything before I posted my message on this forum
    1. Is the Portlet Faces Bridge library in the project libraries?
    yes in both test1 project and ui project. ui project is where the ADF application is and test1 is where the producer is registered
    2. I sent the web.xml earlier in the forum. Yes it include the tags
    here is it again
    <?xml version = '1.0' encoding = 'windows-1252'?>

    3. Yes it include that tag also. Please see the web.xml I pasted above
    4. Yes I deployed it as the simple WAR file and NEVER as a WebCenter Application WAR
    I am assuming that when you refer to web.xml you refer to the one in my ui project where the ADF application is . There is another web.xml file in test1 project where I try to test the portlet. That web.xml is also pasted in my earlier blog
    Any other idea ?
    thanks a lot
    Vijay

  • CreateRow increases memory and cpu. Tomcat+ADF Faces+BC4J in JDev 10.1.3.0

    CreateRow increases memory and cpu. Tomcat+ADF Faces+BC4J in JDev 10.1.3.0.4
    My old problem is this Ineffectiveness/Inconsistency BC4J createrow in tomcat, CPU = 100%,Mem=2.2G
    I have tested my Adf Faces application with jmx in server and, in my machine, jconsole and mc4j.
    When cpu=100% and memory increases, jconsole constantly returned similar trace:
    In all trace, I see that common is:
    oracle.jbo.server.QueryCollection.populateRow(QueryCollection.java:2203)
    oracle.jbo.server.QueryCollection.fetch(QueryCollection.java:2088)
    Therefore, I believe that function populateRow make infinity loop (or fuction fech make infinity loop, called populateRow), but I don’t know populteRow or fetch code.
    tomcat Version: 5.5.16
    Jdeveloper Version: 10.1.3.0.4
    Adf Business component Version: 10.1.3.36.73
    Java version: 1.5.0_05
    Please, any oracle ACE could help me?

    I continued researching. When my server gain cpu and memory in Catalina.out, I can to see this output:

    It’s corresponding to menu.
    I have looking this documentation:
    http://download.oracle.com/docs/html/B25947_01/web_cache002.htm
    In this documentation, first access, the cache miss, but the following times the cache could hit. . When my server gain cpu and memory I look that the following times the cache always miss in all pages. Subsequently tomcat no reply and the malicious thread, execute Armageddon trace. This behavior of the cache is strange, right?
    I’m sure that I’m making anything that fetch in queryCollection make big loop.
    I have redefining getRangeSize and CurrentRow of my CustomViewObject (all viewOjects about my applications extends CustomViewObject and CustomViewObject extends viewObject) and I looked correct rangesize (not -1). I got system.out.println(getFetchedRowCount()) in createRow and obtain 13 or 15. I belive that It’s correct.

  • Help! ADF default behavior rejected by end users...

    Hi,
    We have built an ADF 11g application during the past months. Last week we had our first user acceptance test with a small group of users. The users were very satisfied about the nice looks of the screens. But they had quite a lot of issues with the default behavior of ADF. I'll provide a list of the most important issues below. I hope more people here at OTN have experienced these issues and perhaps have some workarounds. And perhaps Oracle can use lists like this to improve the next version of ADF...
    <ol><li>Multi record edit<br>We have a lot of multi record edit screens. These are all editable tables. Those tables have the following problems:
    <ol type="a"><li>Whenever a partial refresh occurs, the whole table gets reloaded. This takes some time, which is uncomfortable. But the main problem here is that the table does not preserve the scroll bar position. The situation can be improved a little bit by setting the <tt>displayRow</tt> attribute to <tt>"selected"</tt> on the table. This will cause the table to show the selected record at the top of the view port after a refresh. But this still confuses the end users. In their experience the records are randomly jumping around.</li>
    <li>Records are not always inserted at the bottom. (In fact, they are inserted above the selected record.) End users simply expect records to be inserted at the bottom of the table, no matter what. And I can't disagree with them. Isn't there a setting to achieve this in ADF?</li>
    <li>Whenever the user navigates to another record in the editable table, all validation rules on the record he navigates from are fired. That means he cannot leave a required field empty to fill it later. The end users say this is very annoying. We would like to delay all validation until the user presses the Commit button. But as far as I know this is not possible, is it?</li>
    <li>The selected record position is not preserved on a full refresh. Our Commit button forces a full refresh of the page. This sounds like a sensible choice to me. However, users tend to click on Commit quite often. But after a full refresh of the page, the currently selected record in a record set is always reset to the first record in the set. In a large data table, this annoys the users very much. Isn't it possible to preserve the selected record over a full refresh?</ol>
    <li>Annoying validation errors<br>Many end users are annoyed by the somewhat "persistent" validation error messages. In a larger form or an editable table, users sometimes want to ignore an error and first enter other data, before correcting the error. This is hardly possible, because ADF sets the input focus to fields with errors and keeps popping up windows with a list of fields that have errors. We would like to make the validation less "aggressive". It is okay to give a field a red border if it contains an error. But leave the input focus where it is. And don't show any popup until the user presses the Commit button. And even then show the popup window only once.</li>
    <li>ADF BC caching and business rules in the database<br>We have some business rules in our database that automatically fill some fields with default values. We have e.g. a master-details relation, where a value in the master record is calculated based on the values of the detail records. We have set the calculated field in the master record to "refresh after update" and "refresh after insert". Sometimes the value of the field gets refreshed, but sometimes not. Users know that the field should be calculated by "the system", and are asking if they did something wrong if it doesn't. I know we could do the calculation in ADF, but our policy is to have all business rules in the database and to not repeat ourselves (DRY). Is there another way to guarantee that the calculated value in the master record gets updated after an update or insert of one or more detail records?</li>
    <li>Partial refresh loses data<br>If a field causes a partial submit to occur, fields in the same record that were not (partial) submitted before lose their data. This forces us to enable partial submit on all fields. But that causes a delay after moving the focus to the next field and validations to be fired too early.</li>
    </ol>
    I've numbered the items above, please use these number as a reference if you're posting an answer to a specific question.
    Please let me know any solution, even if it is only a partial solution. We've a nasty situation now. Our application is (nearly) finished, but it is blocked for production by the users because of the behavior of the ADF framework, on which we have very little influence. We can't blame the users for that, most of their criticism is fully justified. So we have to come up with a good solution for these issues before we can go to production. So any help would be highly appreciated!
    Best regards,
    Bart Kummel
    PS.
    We're using JDeveloper/ADF 11.1.1.1.0, we deploy to a WebLogic 10.3.1 server and we have an Oracle 10g database. We're using the full ADF stack: ADF Business Components, ADF Bindings and ADF Faces.

    Hi Bart,
    I can answer for few of your questions.

You can write your own method instead of the default createInsert, which would have something like

    vo.createInsert();

  • Creation of object with sub-objects in ADF Faces

    I am trying to create an object that has associated sub-objects (header/detail) using ADF Faces. The user enters the header information in an ADF Form, then he creates detail data. Example: If the object is a PO, user creates the PO header info and, in an ADF table, he creates the PO lines.
    The problem is I am not able to figure how to bind the ADF table to the object that is being created. In a normal master-detail form, you drag the associated list from the Data Control palette and JDev automatically creates an accessor iterator that "feeds off" the master iterator. But, in this case, the associated list does not appear in the data control palette. Nor am I certain that is the right thing to do, anyway.
    Help! This seems like it would be a common pattern.

    Sorry. Here is some more information:
    1. The project is for tracking duplication jobs requests.
    2. Data Model--DocumentTicket and JobDocument objects are EJB 3.0 JPA objects. DocumentTicket has a getter (getJobDocuments) to retrieve a List<JobDocument> of related job documents. JobTicketManager is the session bean that encapsulates most business methods.
    3. I am using ADF Faces bindings to "publish" the data model to the GUI.
    4. In the GUI, I dragged/dropped the DocumentTicket constructor from the data control palette to create the document ticket. This created the appropriate method action bindings, as well as the DocumentTicketIter iterator to iterate over the constructor result.
    5. Of course, the user also needs to specify the related job documents. In the GUI, I would like to have an ADF table that displays the current job documents, and a button labeled "Add Document" that is wired to a pop-up dialog. The idea is that the user clicks on the "Add Document" button, enters the information about the new JobDocument object. The object is then created and the table is updated with a new row. The table is also used to manipulate the list of job documents (chiefly, it allows the user to change their listed order).
    Step 5 is where I am having trouble. I can see how to create the pop-up dialog, how to wire it to the JobDocument constructor, how to update the data model. The problem is: I do not know to which object I should wire the JobDocument table. Logically, I should be able to wire it to the jobDocumentList property. However, that is not displayed in the data control palette under the constructor results (it is displayed elsewhere; for example, under the result of the findAllDocumentTickets method).
    I suppose I could create a separate finder method in the session bean, but then how do I connect it to the object being constructed (i.e., to the JobDocumentIter iterator)?
    Either I am missing something here or I am hitting some limitation of the ADF binding framework.
