How to create JSF UIComponent tree before rendering phase?

Hello,
The JSF lifecycle create the JSF UIComponent tree (I mean : parsing the JSP to buid the JSF component tree) during the restore phase if the request is a postback else during the render phase.
In my application, I need to link JSF component with error message (coming from business layer) like :
FacesContext.getCurrentInstance().addMessage("form1:v1", new FacesMessage("Test!"));To do that, the JSF component with the Id"form1:v1" must exist! And that not the case if the request is not a postback.
A solution should be to build the JSF component tree just before the rendered phase by implementing the a custom PhaseListener. But i dont know how to force JSF to build the JSF component tree?
Is it possible? Other solution?
Thanks!

Sniff! no answer!
May be I have to explain more my issue?

  • How to create JSF application from xsd files?

    Hi,
    We have many xsd files describing xml's which we are supposed to send to web services. Application which we are creating should allow user to fill xml documents with data and then we should send those xml files to some web service. We want to automatize as much as possible the process of application creation to avoid possible errors and to minimize our efforts (there are plenty of quite complex xsd files).
    Our first approach was: we used Oracle JSXB to generate java classes basing on xsd files (using JDeveloper 10.1.3.2.0.4066). Then we tried to generate DataControls, but this action fails with following error:
    Window title: Error in init bean
    Message: Could not complete initbean because it would result in an invalid document
    Details: oracle.bali.xml.model.XmlInvalidOnCommitException: SEVERE: Wartość atrybutu Name nie jest typu ID (Value of Name attribute is not of ID type)
    Wartość musi być następującego typu: (Value must be of following type)
    Nazwa typu: ID (Type name)
    Typ pierwotny: string (Primitive type)
    Z następującymi więzami: (With following constraints)
    zgodne z wzorcem: [\i-[:]][\c-[:]]* (Compliant with template)
    [ node = Name ]
    <JavaBean version="10.1.3.40.66" id="XSLStylesheet" BeanClass="oracle.xml.xslt.XSLStylesheet" Package="oracle.xml.xslt" isJavaBased="true">
    <Attribute Name="classMethodParams" IsUpdateable="0" Type="java.util.Hashtable" />
    We tried Sun implementation fo JAXB - it generated different java classes (with annotation mechanism). Creation of DataControls using those classes was successful. Then we created simple JSF page and tried to put those DataControls on it in order to let the user fill it with data. The thing is that those controls are read only as there is no row created in those DC. We can't create any row in those DC as there are only 'commit' and 'rollback' operations. When we try to call 'CreateInsert' operation on child elements of those DC we get error in JDeveloper log window:
    2007-05-29 10:08:46 oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
    WARNING: JBO-29000: DataControl:createRowData
    2007-05-29 10:08:46 oracle.adf.controller.faces.lifecycle.FacesPageLifecycle addMessage
    WARNING: DataControl:createRowData
    new row is not created and controls are still read-only.
    The question is:
    1. is there another, more efficient way to create JSF application from xsd files?
    2. if this is the best way to do it, what do we do wrong?
    Leszek

    To anyone who might find it useful: our solution to mentioned problem.
    Few tips how to solve described problem:
    1. Do not use JAXB (we checked Oracle and Sun)
    2. Use castor http://www.castor.org/
    a) for each xsd generate java files in separated package
    b) use java 1.5 to let castor generate lists
    c) use mapping of xml namespaces to java packages to have only 1 implementation of each xsd
    3. Create facades - java files for you root-level java objects
    4. Right click those facades and choose 'Create DataControl' in jdev
    5. Now you may drag and drop you DataControls and use them in your JSF (or UIX) application
    I hope it will help someone :)

  • How to create this Hieararchical Tree?

    Hi All,
    Please help me on this issue.
    I need DRILL DOWN functionality in forms. Im trying to Study / Create Hierarchi Tree Concept in Forms 6i, but couldn't able to manage /Understand how to create this. Please any one could help me. and im giving my scenario also here, whether it can support or not.
    Our routes having lot of terminals, like Our Bus travels from KENYA to SOUTH AFRICA passing TANZANIA,ZAMBIA,MALAWI,BOTSWANA countries. so i need the No of records to be dynamic i cant fix 10 records and scroll etc, Rather im trying to use Heirarchi Trees to achive this.
    My Table is like this.
    Table #1 Route_quotas
    Route_no,terminal_name,quota_station_from,quota_station_to,no_of_seats,seat_no_start_from,seat_no_ending
    Data is Like this:
    1,GNT,GNT,HYD,10,1,10
    1,GNT,GNT,VJA,40,11,50
    1,VJA,VJA,KDD,10,11,20
    1,VJA,VJA,HYD,30,21,50
    I need data to be displayed / functoned like this. If One select Route_no 1 in a List_item. Down to that i should show which terminals having quotas in this route. those are.
    GNT
    VJA
    Next ... If One selects this node like if one Expands GNT node the sub nodes should be like this having three coulmns (i.e quota_station_from,quota_station_to,no_of_seats columns)
    GNT HYD 10
    GNT VJA 40
    Next again.. if One select the first subnode it should give ...the seat Nos
    1,2,3,4,5,6,7,8,9,10 (please Omit the commas) and from there i should be able to select one seat_no and do some actions based on that. like RESERVE or ISSUE what ever i like. i need that Seat_no value.
    GNT
    ........GNT HYD 10
    ................ 1 2 3 4 5 6 7 8 9 10
    ........GNT VJA 40
    ................11 12 13 14 15....50
    VJA
    ........VJA KDD 10
    ................11 12 13 14 15 16 17 18 19 20
    ........VJA HYD 30
    ................21 22 23 24 ...... 50
    Thanks in advance.

    Rama,
    I would use nested PLSQL cursors to populate a record group and create the tree from there. This way you can also concatinate multiple values to show as a single name in a tree.

  • How to create a decision tree in ABAP (in SAP or not, and how????)

    Hello,
    I have to create a decision tree which has to be called within a BAPI.
    This tree finally has to return 1 single value.
    Can you tell me what's the best solution for this ?
    Should I do this with abap, or should I call a webapplication which provides this tree for me ?
    It would be great if you could provide some example-code for me.
    Kind regards,
    Gert-Jan

    I am not sure I understood what you meant by decision tree. If you are simply talking about arriving at an answer based on one or more inputs, then it is a simple IF ELSEIF ELSE statements or CASE statements.
    Can you please elaborate/give example of what you mean by decision tree?

  • How to create a dynamic tree report

    hi experts,
           i have a requirement to create a dynamic tree report in OM module.
      this report should show the number of people positions required in a org unit, and also the number of people available in a org unit.
      There is something called as qualification catalog to which qualifications are attached, to these qualifications org units are attached, these org units will have some positions attached to it, and each of this position might have a person attached to it.
    The user will enter the qualification catalog number in the selection screen for which he should be getting the result in a tree format which flows from qualification catalog to qualifications, from qualifications to org units, from orgunits to the total no of positions present in this orgunit and the no of positions occupied in the orgunit.
      This is a challenging job as far as i am concerned.
    Please suggest me a way to approach this,i promise to reward the answers.

  • How to create 2 output signal locked in phase from a one input signal

    Hi all,
    I have a case in which I want read in a signal analog input (voltage) from a photodiode, I want to create a 2 sinewave signal locked in with same phase as the input signal and output them as analog output to my 2 laser diode. the frequency of the input signal is low aroud 15 Hz , the 2 output signal i want to be  around 120 hz and 150 hz . 
    I am using USB - 6003 daq card.
    I have created a vi to see the input signal but I dnt know how to create 2 signal from the waveform generator locked in the phase as the input signal. I have seen a PLL vi , but dont know how to use that with my program.
    can any one tell me how to proceed.
    thanks

    Hi AnkitG,
    Here are a couple of links that might help you understand a little more how the PLL work and a way to synchronize the task to perform a PLL.

    Also, you should be able to find a lot of examples on how to accomplish the synchronization of tasks on the community, if you consider that the only consideration is that both must start at the same moment. 
    I hope, these examples might show you some useful concepts:

  • How to create a new tree node with the initial edit function

    Hi all,
    I would like to mimic the Windows system when the user creates a new node. The newly created node should be in the edit mode, i.e.it should
    be highlighted and the cursor should be appear at the end of
    the newly created node name.
    I have the folloing code after I create the new node and set its selection:
    TreePath selectionPath = getTree().getSelectionPath();
    tree.startEditingAtPath(selectionPath);
    However, this only partially does what I want, the cursor does not appear at the end of the node's name and I am not sure how to select the text name of the new node.
    I hope someone can help.
    Kanita

    I haven't tried myself but my guess is that you need to customize your tree cell editor for putting
    cursor at specific position, etc.
