[Solved] Create Components Dynamically

Hi,
I am using JSF + ADF bc for creating web pages.
I have to create some components, says outputText, dynamically when the page loads.
How can I do this?
Thanks,
Prasanna

HelloPrasanna

Hi,
the output text component is CoreOutputText. You create a new instance through
CoreOutputText co = new CoreOutputText();
the you need to append this as a child to the parent. So if the parent is a form then you need to get a hold of the form. This can be done through a Binding reference - a managed bean reference of the form binding property. JSF doesn't have an onLoad notification, so you either use a PhaseListener to create the new component, or you piggyback on the set method of the parent component

  • How can I avoid running out of memory when creating components dynamically

    Hello everyone,
    Recently, I am planning to design a web application. It will be used by all middle school teachers in a region to make examination papers and it must contain the following main functions.
    1)Generate test questions dynamically. For instance, a teacher who logs on the web application will only see a select one menu and a Next Quiz button. The former is used for determining the number of options for the current multiple/single choice question. The later is dedicated to creating appropriate input text elements according to the selected option number. That is to say, if the teacher selects 4 in the menu and presses the Next Quiz button, 5 input text form elements will appear. The first one is for the question to be asked such as "1.What is the biggest planet in the solar system?", the others are optional answers like a)Uranus. b) Saturn. c)Jupiter. d)Earch. Each answer stands for an input text elements. When the teacher fills in the fourth answer, another select one menu and Next Quiz button will emerge on the fly just under this answer, allowing the teacher to make the second question. The same thing repeats for the following questions.
    2)Undo and Redo. Whenever a teacher wants to roll back or redo what he has done, just press the Undo or[i] Redo button. In the previous example, if the teacher selects the third answer and presses the Delete button to drop this answer, it will delete both the literal string content[i] and the input text element, changing the answer d to c automatically. After that, he decides to get back the original answer c, Jupiter, he can just click the Undo button as if he hadn�ft made the deleting operation.
    3)Save the unfinished working in the client side. If a teacher has done half of his work, he can choose to press the Save button to store what he has done in his computer. The reason for doing so is simply to alleviate the burden of the server. Although all finished test papers must be saved in a database on the server, sometimes the unfinished papers could be dropped forever or could form the ultimate testing papers after several months. So if these papers keep in the server, it will waste the server computer�fs room. Next time the teacher can press the Restore button on the page to get the previously stored part of the test paper from his own computer and continue to finish the whole paper.
    4)Allow at least 1,000 teachers to make test papers at the same time. The maximum question number per examination paper is 60.
    Here are my two rough solutions,
    A.Using JSF.
    B.Using JavaScript and plain JSP[b] without JSF.
    The comparison of the two solutions:
    1)Both schemas can implement the first and the second requirements. In JSF page I could add a standard panelGird tag and use its binding attribute. In the backing bean, the method specified by the binding attribute is responsible for generating HtmlInput objects and adding them to the HtmlPanelGird object on the fly. Every HtmlInput object is corresponding to a question subject or an optional answer. The method is called by an actionListener, which is registered in the Next Quiz commandButton, triggering by the clicking on this button in the client side. Using JSF can also be prone to managing the HtmlInput objects, e.g. panelGird.getChildren().add(HtmlInput) and panelGird.getChildren().remove(HtmlInput) respond to the undoing operation of deleting an optional answer and the redoing operation of the deleting action respectively. I know JavaScript can also achieve these goals. It could be more complex since I don�ft know well about JavaScript.
    2)I can not find a way to meet the third demand right now. I am eager to know your suggestion.
    3)Using JSF, I think, can�ft allow 1,000 teachers to do their own papers at the same time. Because in this scenario, suppose each questionnaire having 60 questions and 4 answers per question, there will be approximately 300,000 HtmlInput objects (1,000X60X(4+1)) creating on the server side. The server must run out of memory undoubtedly. To make things better, we can use a custom component which can be rendered as a whole question including its all optional answers. That is to say, a new custom component on the server side stands for a whole question on the client side. Even so, about 60,000(1,000X60) this type of custom components will be created progressively and dynamically, plus other UISelectOne and UICommand objects, it also can�ft afford for most servers. Do I have to use JavaScript to avoid occupying the server's memory in this way? If so, I have to go back and use JavaScript and plain JSP without JSF.
    Thank you in advance!

    Thank you for your quick response, BalusC. I really appreciate your answer.
    Yes, you are right. If I manually code the same amount of those components in the JSF pages instead of generating them dynamically, the server will still run out of memory. That is to say, JSF pages might not accommodate a great deal of concurrent visiting. If I upgrade the server to just allow 1,000 teachers making their own test papers at the same time, but when over 2,000 students take the same questionnaire simultaneously, the server will need another upgrading. So I have to do what you have told me, using JS+DOM instead of upgrading the server endlessly.

  • How to set/get value in dynamically created components?

    I need to create dynamically form based on definition written in database.
    I created an empty panelGreed in my jsf page
    <h:panelGrid columns="2" id="parseg"
    binding="#{ParsegBean.uiKatparam}">
    </h:panelGrid>I can�t use dataTable, because my form contains various component types (SelectOneMenu, OutputText, and InputText).
    In my bean I create components dynamically:
    Private UIPanel uiKatparam = null;
    Iterator componentIt = myComponentList.iterator()
    while(componentIt.hasNext()){
         MyComponent myComponent = (MyComponent)  componentIt.next();
         HtmlOutputText prompt = new HtmlOutputText();
         prompt.setValue(myComponent.getPrompt());
         prompt.setId(myComponent.getPromptId());
         uiKatparam.getChildren().add(prompt);     
         switch (myComponent.type) {
         case 1: //InputText
              HtmlInputText iText = new HtmlInputText();
              iText.setId(myComponent.getId());
              iText.setValue(myComponent.getDefaultValue());
              uiKatparam.getChildren().add(iText);
              break;
         case 2: //SelectOneMenu
              HtmlSelectOneMenu selectOneMenu = new HtmlSelectOneMenu();
    // �
              uiKatparam.getChildren().add(select);
              break;
         default:
              break;
    }When I try to get values in my Action:
    Iterator it = myBean.getUiKatparam().getChildren().iterator();
    while (it.hasNext()) {
    Object ob = it.next();
    if (ob.getClass().getName().matches(".*HtlmInputText")) {
    HtmlInputText t = (HtmlIputText) ob;
         String id = t.getId();
         String value = (String) t.getValue();
    //�
    //�
    }and value is still equal initial value

    I solved my problem creating UIData with dynamically added and dynamically rendered components (in each row is rendered another component).

  • How can I create UI components dynamically based on the result of WebService/HttpService call?

    I would like to create child components of the component
    based on a XML which is retrieved by WebService/HttpService call.
    createChildren() is the one to be used to create components
    dynamically. But if I use createChildren() and call a
    WS/HttpService request in createChildren method, I can not get the
    result of WS/HttpService request in createChildren().
    It seems that the result event is processed later after
    createChildren() is completed.
    How can I implement my requirement?
    I would appreciate any pointer or suggestion.
    Best regards
    Masa

    1) Use a List, with a custom itemRenderer
    2) Use a Repeater (Probably easiest)
    3) use Actionscript to addChild() components.

  • Dynamically creating components on the page gives problems

    Hello,
    we are creating a number of custom UI components dynamically on the page, depending on informations we only know at runtime (for some reasons, we could not just create them statically and hide and show them dynamically- please don't suggest doing this way for now).
    The custom components are derived from ADF components, this way, as an example:
    public class MyRichInputText extends RichInputText implements Serializable {
    }They are successfully created dynamically in a bean associated with a button and used for the first time. That is, once wle navigate the page, for example via tabs or fragments, we always get a "Session timeout" exception. Below is the log from the server:
    <Error> <org.apache.myfaces.trinidadinternal.application.StateManagerImpl> <BEA-000000>
    java.lang.InstantiationException: mycompany.lib.MyRichInputText
         at java.lang.Class.newInstance0(Class.java:340)
    <Warning> <oracle.adfinternal.view.faces.lifecycle.LifecycleImpl> <BEA-000000> *<ADF_FACES-60098:Faces lifecycle receives unhandled exceptions in phase RENDER_RESPONSE 6*
    java.lang.NullPointerException
         at oracle.adfinternal.view.faces.lifecycle.LifecycleImpl._renderResponse(LifecycleImpl.java:978)
    javax.faces.application.ViewExpiredException: viewId:/myPage - ADF_FACES-30107:The view state of the page has expired.  Reload the page.
    Also, just to your knowledge, we use javax.faces.STATE_SAVING_METHOD="client" in web.xml. Note that MyRichInputText is already Serializable.
    Do you have any solution?

    Hello Frank,
    thanks for the quick answer. Below is the full stack. I think it will be difficult to quickly change all the code by building RichInputText directly. I'll do my best to be back to you with all the necessary informations as soon as possible. However, for now, if you have any possible idea by just look at the following more accurate log, let me know:

  • Dynamically created components in a gridpanel and rendering

    Problem: I have a gridpanel in a PORTLET that I fill with components dynamically. I do it in the init() method. After submitting the page, the components are created from scratch in the init() (I write their values in the log and everything is OK).
    Then the page should be rerendered. But it is not. No matter what I do, the page is rendered as it looked like for the first time.
    If I navigate to another page and then back, the page is rendered OK.
    How to avoid that? I really need help with this, because I need to create a custom tree-like structure with textfields and buttons. The standard tree component is of no use (it doesn't work in portlets anyway).

    Try to move the code to the getGridPanel(), instead of in the init()

  • How to create a dynamic link in a Form to link to a specific FOLDER

    Hello,
    I have created a reports of all employees of my department.
    This reports shows me the empno and ename
    When I clicked on a empno ( for example empno = 1 ) then then I got a MASTER DETAIL FORM about that employee(empno = 1) .
    Who he or she is and which course he or she had followed.
    I want create a dynamic link in the MASTER DETAIL FORM which shows me directly the folder of that employee ( in this example folder 1 ).
    If I clickt on the report with all employees of my department on an other number ( for example empno = 3333333) then if I click on the dynamic link in the MASTER DETAIL FORM I want to see the folder of employee 3333333 !!! You know what I mean ?
    What I want to know is, how to create a dynamic link that shows me directly a folder which is dependent on which empno I had clicked on in the report ( report with employee numbers and ename )
    Is there any way to pass some parameters into a link to a Folder ? Is this possible in Portal ? Does anyone know how to do this, or do you have a suggestion how to solve this problem ?
    Thanks a lot !!!
    Chu Lam

    Hi Chetan,
    I am glad that someone had replied on my question.
    I will explain it to you again.
    I have created a report that shows me all employees. If I click on a employee number then I get an MASTER DETAIL FORM on my screen with all the information(where he works now and which number I have to dial ifhow can I reach him by telephone) of that employee on which number I clicked on.
    I really like this mechanism. (You click on a number and the information that you see in the next screen is dependent of the number you clicked on ! )I have created all this. It works fine.
    What I want is to expand this example.
    Every employee has a FOLDER (yes, those ones in Content Area ) which they can insert text or image into that folder. The folder name is just the employee number. ( employee with employee number 3303, he owns a folder which is named 3303 and an employee with empno 9999, he or she owns a folder with the name 9999. )
    Every employee can tell more about himself in that FOLDER by iserting text and images. For example : What he likes, pictures of his vacation, something like this.
    What I want is this :
    If I click on the first report,which provides me all employees on screen, on a employee number 3303 then I get a Master Detail Form on my screen with all information about that employee with employee number 3303. And I want in this MASTER DETAIL FORM to create a link that shows me directly the FOLDER of that employee ( 3303), so I can learn more about employee with employee number 3303. But I don't know how to create this link.
    That link had to be dependent on the employee number. The difficult thing about this link is that this link had to be dynamic.
    I hope this will make it clear to you :
    (report all employees:)
    empno ename
    3301 john smith
    3302 peter clark
    3303 wilson jones
    If I click on a empno ( for example 3303) then I get a MASTER DETAIL FORM which provides me information.
    (MASTER DETAIL FORM )
    EMPNO 3303
    ENAME wilson jones
    department New York
    mobile number 98908763
    Company tel. no day
    AOL 097485838 monday till wednesday
    Oracle 04848584333 thursday and friday
    LINK
    (what I want is to create a link here )
    If I click on LINK in this MASTER DETAIL FORM then I want to link to the FOLDER of this employee ! ( In this example it is FOLDER 3303.
    BUT IF I CLICKED ON THE FIRST REPORT ON A DIFFERENT NUMBER ( FOR EXAMPLE 3301) THEN IF I CLICK ON LINK IN THE MASTER DETAIL FORM THEN I HAVE TO LINKED TO FOLDER 3301.
    I just want to know how to make a link like this ( create a dynamic link to a specific folder ).
    Thanks in Advance.

  • Error while creating a dynamic internal table refers to custom field

    Hi all,
    I am getting the exception TYPE_NOT_FOUND when I try to create a dynamic internal table using:-
    DATA: gr_desc TYPE REF TO cl_abap_typedescr.
    gr_desc = cl_abap_typedescr=>describe_by_name( p_field ).
    The field p_field is a Z-field inside a DB table, (e.g. a user added field in MARA). The statement fails at that point and gives a runtime exception. Any suggestions to how I may solve this problem? Or any alternatives for the same? I guess we face this issue for all custom fields..has SAP released a note for this??
    Thanks..

    that's just the wrong method, you should use DESCRIBE_BY_DATA
    gr_desc = cl_abap_typedescr=>describe_by_data( p_field ).
    Note: DESCRIBE_BY_NAME is to be used for referencing a DDIC type by its name. Example:
    gr_desc = cl_abap_typedescr=>describe_by_name( 'MARA-ZZFIELD' ).

  • Create Multiple dynamic Node in Web Dynpro Abap

    Hi Friends,
          I need your help.My object is to create Multiple dynamic dropdown UI element.I am able to create this dynamic Dropdown element. But i need to assign default different values to this dropdown elements.So i created dynamic nodes for each dropdown and created attribute with same name as that of value table.
       My issue is its giving me error as : -
    Lower-Level Node with Name ZDCN_BRD_STATUS.ME Does Not Exist
    Help me to rectify this error..
    Regards,
    Santosh

    Hi,
    This information is not enough for anybody to help you. Write more in detail about your code and where exactly in the code this error is coming.
    One trial experiment can be that you split your problem into two or more level.
    Create several nodes in your context with attribute and sample data.
    Create Dynamic UI (DDBI) and Bind these attributes to your DDBI.
    When it works perfectly, then tryout how to create the Node and attribute dynamically. This way you are not making it too complex to solve this problem.

  • Creating a dynamic Array

    Thanks for reply.
    I want to create a dynamic array and for this I used ArrayList Collection and Vector Class. I am using JDK 1.4.1 . But , I have a problem in that. In ArrayList, I used the following code:
    ArrayList al = new ArrayList();
    while(rs.next())
    al.add(rs.getString("Enter_Year"));
    al.add(rs.getString("UG_Production_Mi_Te"));
    al.add(rs.getString("OC_Production_Mi_Te"));
    al.add(rs.getString("Total_Production_Mi_Te"));
    al.add(rs.getString("OBR_MM3"));
    al.add(rs.getString("OMS_Te"));
    al.add(rs.getString("Coal_Offtake_Mi_Te"));
    al.add(rs.getString("Supply_to_Steel_Plant_Th_Te"));
    al.add(rs.getString("Royalty_SalesTax_MP_Crs"));
    al.add(rs.getString("Royalty_SalesTax_CG_Crs"));
    al.add(rs.getString("Total_ManPower"));
    al.add(rs.getString("Fatality_Rate_per_Mi_Te_Output"));
    al.add(rs.getString("Total_Wellfare_Expenditure_Crs"));
    String rpt[][] = new String[al.size()][];
    rpt = al.toArray(rpt); // ArrayStoreExecption error
    String colheads[] = {"...........My Table's Column names are here....."};
    JTable table = new JTable(rpt,colheads);
    JScrollPane jsp = new JScrollPane(table);
    add(jsp);
    At the statement having comment line I received the error ArrayStoreException. The JTable accepts the 2 D array for storing the info and I think the toArray() method is not working there and can't convert the ArrayList elements into an Array. Similarily, Vector Class is also not converting the elements into an array object and showing the same error only.
    Please help me to convert it into an array object so that I can pass it into the JTable argument.

    That isn't a jdbc problem but rather a collection problem.
    You certainly can't convert a one dimensional collection into a two dimensional array automatically. And that is what you are creating with the while loop.
    Since you know the column names you also know the inner array size so you can start by creating a statically sized string array (not collection) in the loop and add that to the outer collection. That might solve the problem.

  • Help me to achieve my goal: creating a dynamic CQ5 website from a CRX Imported Site

    Hello everyone.
    For two weeks now, i'm trying to create a dynamic content CQ5 website from an imported CRX site.
    What I already did and where I am now:
    Step 1 - I have imported a website using the CRX Import Site tool.
    Step 2 - I have done some mappings in my imported site images and texts. In the CRX content repository estructure, I can found the mappings as
    unstructured nodes, at "etc/designs/mysite/dev/mappings", the component properties matching the components I selected in the component extractor;
    Step 3 - I have done some extractions in my imported site images and texts. In the CRX content repository estructure, I can found the extracted components
    at "apps/mysite/resources/images" (the last two ones I created myself);
    Step 4 - After done all these steps, I acessed the Web Sites CQ5 menu and selected the "New Site" option, in the "New..." button. A "MySite Blueprint" is avaliable
    to be selected as a Blue Print to my new site, but If I select this one and create my new site, not all the mapped components can be manipulated or selected and some
    mappings just show on as an empty selection box in the page, where I am able to insert images, for exemple.
    In short, after all these steps, I still can't do what I want with my mapped components and the new site is, basically, the same as the imported. Not every mapped components can be selected and edited and I can't change my site template or content (the far I got here is add a new image in the site, but without the liberty to change the position).
    So, what I'm forgetting? Is there some step that I don't getting through? Maybe I need to work on the template created by the site importer?
    Is there some material or media that can help me or maybe add knowledge to me?
    Already read the "Site importer" and "Components" in Adobe CQ5 Documentation but don't get me far from where I am now.
    If someone can help me to make this process better, with more liberty on my new site and the possibility to control all the components, adding new ones
    or editing the existent ones, I'll be very gratefull and with a great new knowledge.
    Operational System: Windows Server 2008
    CQ Version: CQ 5.4.0.20110218
    Thanks.

    I want to do this using the site importer because I want to show my clients how we can make content management and experience customizations a lot easier starting by their own websites.
    So, importing my customer website and transforming it in a new CQ website is the way to show this.
    Anyway, thanks in advance and I'm going to look at the page component for the website that I imported.
    If someone got another tip or hint, I'll be very thankfull.

  • Problem with tutorial:Creating a dynamic playlist for streaming flash video

    hi, anyone tried the tutorial: creating a dynamic playlist
    for streaming flash video?
    i follow the instruction exactly as stated in the tutorial
    and test the fla file, it worked perfectly well when i open the swf
    using the macromedia flash 8. Everything look fine. Nothing is
    changed except the url is changed to "rtmp://localhost/videosource"
    in the xml file.
    after i publish the file using the setting: access network
    only, i try to open the swf and html file from the folder, the
    thumbnail did not appear and there is no way i can click on any
    videos. What i see is only the list, and there is no response from
    the flash media server 2. All the files is in the same folder.
    Anyone please help with this problem???? thanks

    ....i debug the movie step by step
    and realised that the xml file is being read by the code...
    Your original problem stated it worked but not when playing
    outside the
    Flash authoring environment by simply loading the swf from
    the hard drive.
    The Flash authoring environment is a trusted environment and
    so you really
    need to test in the actual deployment mode which loading an
    swf from the
    hard drive is not a valid deployment unless an installed
    Flash player is
    available outside the web browser which you would have as you
    have the
    authoring tool and your users will not.
    Use a browser with
    http://yourdomain.com/yourmovie.html
    to do final
    debugging.
    In this regard you may need to debug the movie while running
    in real time
    mode in a web browser with
    http:// A technique to trace I suggested is to
    create a temporary TextField perhaps named out_txt and send
    trace message to
    it such as out_txt.text += "My Trace Expression".

  • Creating a dynamic jtree using datas retrieved by dom in xml parsing

    help me with code to create a dynamic jtree using data retrieved as nodes by xml parsing using dom

    Ok, so you want to make a tree. To determine the data that appears in a tree, you have to make a custom tree model. The API for this is at :
    http://java.sun.com/j2se/1.4.2/docs/api/
    A tutorial for using trees is at :
    http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html
    I assume you are going to be using Nodes, since you are using XML. For this I might start with something like
    class NodeTreeModel implements TreeModelI would then implement the 'getChildCount()' as the number of subnodes a node has, and the value of a tree node to the nodes value.
    Hope that starts you off.

  • Failure in creating a dynamic structure

    Hi Guys,
    i get a strange failure while creating a structure from components.
    lr_out_tab ?= cl_abap_tabledescr=>describe_by_data( it_outtab ).
    lr_out_struc ?= lr_out_tab->get_table_line_type( ).
    lt_out_comp  = lr_out_struc->get_components( ).
    lr_new_struc  = cl_abap_structdescr=>create( lt_out_comp ). <-- cx_sy_struct_comp_name exception
    I get this failure, when i have component-names like xxx-yyyy. Does somebody have an idea how to slove this.
    Greetings
    André

    Hello Andre,
    You're getting the error message because the param P_STRICT of the method CREATE( ) is set to TRUE(by default).
    If you set the creation mode as "strict"(P_STRICT = CL_ABAP_STRUCTDESCR=>TRUE), no special characters are allowed in the column names! Since your component names contain a '-' you're getting the exception CX_SY_STRUCT_COMP_NAME.
    If you set the creation mode as "non-strict"(P_STRICT = CL_ABAP_STRUCTDESCR=>FALSE), following spl. characters are allowed:
    #$%&*-/;<=>?@^{ | }
    So in your call you need to set the "non-strict" mode while creating the dynamic structure:
    *   Get the Dynamic structure definition
        TRY.
            lo_structdescr =
              cl_abap_structdescr=>create(
                  p_components = lt_struc_comp
                  p_strict     = cl_abap_structdescr=>false ).
          CATCH cx_sy_struct_creation .                     "#EC NO_HANDLER
        ENDTRY.
    Hope i'm clear.

    Is this possible in LiveCycle, if so, can you please provide the script/info - as needed.
