Lifecycle phase for Single ADF Bounded Page

Hi,
I registered a Page LifeCycle listener for single ADF bounded page in 'ControllerClass' property of pagedef file. When i m evaluating a simple condition for a lifecycle phase, it is executing two times.
The Listener class is also a managed bean with scope of session, registered in adfc-config.xml file . This i am doing in Jdev 11.1.1.3 .
Why it is happening & how to corret this ? Can anyone help me?
   public void afterPhase(PagePhaseEvent pagePhaseEvent) {
        if(pagePhaseEvent.getPhaseId() == Lifecycle.PREPARE_RENDER_ID){
          System.out.println("After Phase : " + Lifecycle.getPhaseName(pagePhaseEvent.getPhaseId()));
public void beforePhase(PagePhaseEvent pagePhaseEvent) {
}Regards,

Frank,
Actually i m executing a managed bean method in afterPhase of PREPARE_RENDER_ID. Method is executing & providing the result in console, but unable to refresh the af:table. I m trying to refresh table programmatically by
AdfFacesContext.getCurrentInstance().addPartialTarget(this.t2) , where t2 is binding instance of af:table. But it is not working. Anyway, on calling method its not executing twice, but sop statement executing twice.
    public void afterPhase(PagePhaseEvent pagePhaseEvent) {
        if(pagePhaseEvent.getPhaseId() == Lifecycle.PREPARE_RENDER_ID){
          //System.out.println("After Phase : " + Lifecycle.getPhaseName(pagePhaseEvent.getPhaseId()));
          this.get_empid_for_nationality();       //this method is populating a ArrayList collection used for populating af:table
          AdfFacesContext.getCurrentInstance().addPartialTarget(this.t2);
}

  • How do I change filename for single-image HTML pages in web gallery for LR 3

    Hi,
    I would like to change the default filename for the HTML pages produced by Lightroom 3 in the web gallery. Specifically, I would like to remove the string "_large" from the HTML filename, so it corresponds exactly to the image filename.
    Specifically, the URL by default is like this:
    http://www.mysite.com/content/_c_EMT2146_large.html
    and I would like it to be like this
    http://www.mysite.com/content/_c_EMT2146.html
    I assume there is some way to make this change using the template editors, but I can't figure it out.
    thanks,
    James Riemermann

    Turns out there's a fairly easy way to change that on Windows, but I can't figure out an equivalent on a Mac, which is where the need is. On windows, I can edit (after backing up) the following two config files:
    C:\Program Files\Adobe\Adobe Photoshop Lightroom 3.6\Shared\webengines\default_html.lrwebengine\grid.html
    C:\Program Files\Adobe\Adobe Photoshop Lightroom 3.6\Shared\webengines\default_html.lrwebengine\manifest.lrweb
    In which the "_large" string is appended and can be removed, following which the gallery works exactly as I would hope.
    But I can't find the equivalent files on the Mac, though I would assume they exist.

    Nic, for me the iTunes window looks like this, when I connect my iPad 3:
    I select the iPad in the "devices" section of the Sidebar (use: "View > Show Sidebar" if the sidebar is hidden).
    Click the "Apps" tab in the "Devices" pane.
    Scroll all the way down in the Devices pane to "File Sharing" "Apps" section.
    Then do I click "GarageBand" to select the documents in the right panel.
    Which part is different for you? Perhaps you could post a screenshot?

  • Single Sign On Page deployment for https

    I created customized Single Sign On page for my application. For this customized page i updated the table WWSSO_LS_CONFIGURATION_INFO$ with
    "http://servername:7777/contextname/x.jsp UNUSED UNUSED". For this Single Sign On page is working fine.
    I enabled SSL for Http Server (its working in 4443 port). Now i can update WWSSO_LS_CONFIGURATION_INFO$ with "https://servername:4443/contextname/x.jsp UNUSED UNUSED". But my doubt is how both these urls(with different ports 4443 and 7777) will be enabled for both http and https.

    Use J2EE session variables and give every application the

    Even if it is legal, have you tried moving them out of there (just to pinpoint a possible bug since the stacktrace indicates a wait on a jar file)?Indeed. If that clears up the issue it is good information to put in a JSF bug report (which may even cascade to the Glassfish level).
    Putting resources in a jar file is only really useful when you want to share those resources among different web applications, which should be a rare case. Even when it happens I would probably still choose to simply copy the resources so they are individually managed and you don't get unnecessary dependencies between applications. Just because something is technically possible doesn't make it a good idea.

  • Separate project for each ADF task flow?!

    Hi,
    We have a BPM process application which is having a few human tasks. The form for each of the human tasks is similar. We’d like to be able to share some page fragments or code between them and create single web application to handle all the human tasks for this BPM process application. Then I found the following in the Oracle document “Developer’s Guide for Oracle SOA Suite 11g Release 1 (11.1.1.4.0)”:
    “If the SOA composite contains multiple human tasks, create a separate project for each ADF task flow associated with each human task.”
    I wonder if we have to do that and if so, what is the reason.
    Do you have any clue? Please help.
    Thanks a lot,
    Helen

    Hi Helen
    1. I do not know the reason why they mentioned like separate project for each human task. NO, this is not required and we can have just one UI Project like MyTaskForms and have all the JSPs in this same project for each Human Task.
    2. On our side, we have like 10 Human Tasks, all using the same Payload. So we have 10 .task file. For the very first .task file, we used Auto Generate Project and gave project name like OurAppTaskForms. The reason we did this is, so that it adds all the required dependent libraries, tag libs etc properly. For all remaining 9 .tasks file, we did NOT use auto generate. Instead we used standard New -> JSF From Human Task and select one task at a time and follow the steps. These steps are covered in the online documentation. At the end in our BPM App, we have just one UI Project with all the 10 screens.
    3. ALSO, all the 10 screens have some common data. This we put in a reusable JSF Fragment page. And associated a custom Managed Bean for this to set and get values from this fragment and also some Actions for some buttons in the JSF. Then we included this JSF in each taskform jsf file, uisng the include tag. We added this include tag, somewhere in the top. So all screens share common jsf fragment page.
    4. We can refine the above stuff further. As per above, we still have 10 JSF screens for each one of the 10 .tasks. Ofcourse all these 10 jsf have same common jsf fragment. BUT instead of 10 individual jsf screens, we can have only ONE Jsf screen also. Refer online docs for the details. The challenging part is, since we have only one jsf, there may be some bussiness stuff, validatoin stuff to take care of in custom ValidationCallback Handler classes. Say for Task1, we had to show some buttons, but NOT for Task2. So we had to handle this logic. Also in validation call back, we can always get each Tasks, title also. So we can workaround this issue also. We are in the process of doing this right now. But first 3, we already did and they are working fine.
    My personal suggestion is first go with single jsf fragment and include in all tasks jsp files. Any changes to common elements need to make only in one place i.e fragment page.
    Thanks

  • JBO-35007 in Portletized ADF Faces Page and alternative scenarios

    Hi all,
    I've started a new thread to address one of the problems referred to here Issues with Faces -> Portlet Bridge and ADF Faces
    In short, the issue arises when portletizing an existing ADF Faces page that uses an ADF BC bound af:Table on the page. I've got a very simple ADF Faces page that has an af:Table on it bound to the employees table in the Oracle HR schema. The af:Table allows sorting and has an af:selectTableOne in it's selection facet which contains an af:commandButton. The app works fine when run as a JSF page.
    However, when I use the JSF-Portlet bridge to publish the page as a portlet (following all of the steps in the Web Center Developer's guide, including changing the state_saving_method to "server"), and placing the portlet on a ADF Faces page in a different project, I can consistently create JBO-35007 errors by:
    * Sorting the data in the portlet by clicking the column header
    * Selecting a different row and pressing the af:commandButton
    Clearly, the current row of the iterator is not being saved properly. I can (of course) "fix" this behavior by setting EnableTokenValidation to "false" in the page definition of the ADF Faces page that has been portletized, but this has obvious side effects.
    Should this behavior work as I am trying to implement it? Perhaps it doesn't make sense to "select" an item in a portlet like this (what am I going to do, as the parent application doesn't have access to the selected row information).
    I can, however, think of a good use case:
    User is using a web-store type application to browse items and add them to his shopping cart. Off to the side, we've got a portlet that shows recently purchased items for the user. User clicks item in that portlet (or selects and hits submit - as in my non-working example, above) and then the main web store application navigates to that item in the "main" section. How could I implement something like this? Any navigation case in the portlet is not exposed to the main application. Perhaps there is a different model by which to do this.... I cannot use a PDK event-type approach (this limits my use of Faces to create portlets), so I'm in a bind.
    Thoughts and discussion much appreciated,
    John

    Peter,
    This should be so simple to re-create; here's my project: http://download.yousendit.com/F017E4D457FFA7F3
    It uses the HR sample schema from a stock 10gr2 database. Be sure to set up the ADF BC connection in the model project, build and deploy the portlets, then try running TestPage.jspx in the UserInterface project. You can play around with the pagedef in the Portlet project to see the JBO-35007 error - right now, EnableTokenValidation is set to false - you can change it to true to see the error.

    The site you link works ok for me. Try reloading the page using Ctrl + F5 if that does not work then try clearing cookies for the individual site.

  • XML file Upload in ADF UI page

    Hi,
    I have following requirement:
    a) There will be an upload button on the ADF UI page.
    b) The ADF UI will allow user to browse and select the XML file
    c) Once XML file is selected there will be a Load button.
    Note: I am fine till step c)....
    d) Upon the Load, UI Screen should be populated with the XML content.
    e.g. UI screen will have Book Title and Author text boxes and the data for Title and Author should be loaded from XML file.
    e) Once data is loaded in ADF UI page (from XML) , it should allow user to modify Title and Author in UI screen.
    f) After modifying the data, user should be allowed to save modified content either in XML file or Database.
    Note: On the OTN forum I posted similar question and I found the partial solution of using the URLConnection Data control, however this data control does not allow you to modify the content on the ADF UI page.
    Thanks

    Hi,
    Note: On the OTN forum I posted similar question and I found the partial solution of using the URLConnection Data control, however this data control does not allow you to modify the content on the ADF UI page.
    Not quite true what you say. The data control shows the data as read only. However, setting the updateable property on the metadata will allow you to create an input form, which is editable. For this, in the Data Control for the URL data control, select the collection and choose "Edit Definition" from the context menu. Select Attributes and if this doesn't show the attributes, follow the link in the Attributes field. Then select each attribute and set the updateable property using the PI
    The question then is how you perform the update, which is what the URL data control doesn't do for you. For this you need to expose methods in a POJO that you then expose as a POJO data control. With your knowledge about the location and name of the XML file, you can then use JAXB to upload the XML, or a database bound collection (EJB, ADF BC or JDBC) to write changes to the database. Note that JAXB could also be used read from teh XML file and show the data in the UI using the JavaBean Data Control.
    To access the object to use for updating the XML file or the database, you use ((DCIteratorBinding)bindings.get("IteratorNameInPageDef")).getCurrentRow().getDataProvider()

  • Display the status of parallel human tasks in ADF web page (BPM 11g)

    Hi,
    We create a BPMN process (BPM 11g) which splits into parallel branches. Each branch has its own user activity. We want to show the task status of ALL the parallel user activities (running or completed) in the ADF web page implemented for the user activity so the user would have the whole picture of the process.
    In another words, we are able to check the status of the component instances associated with the process instance in the Oracle EM. We want to provide the similar information (in our case, we only want to show the status of the human task components) to the user when they access the human task page.
    I wonder if the only solution is to write Java code with the API to lookup the BPMN process instance. We try to avoid Java coding if possible. Please advise. Also, so far, I have not found any complete instruction/document on how to access the BPMN process instance and check the tasks etc. through the API. Please help if you know where I could get such information.
    Thanks a lot,
    Helen

    in that I should be able to modify & save the long text in my ZTABLE and
    able to retrieve the same text for single clicked icon record.
    which function modules/Classes/Methods can we use for this requirement.
    And how retrieve the same text for this record.

  • Is there a Special Character for the number of pages in a document?

    I'm creating a template (in cs6) for a series of documents of variable length, and each document needs to be numbered with the format, "page A of Z." I see the special character for inserting the current page number (A) and I'd like to have the number of pages in the document (Z) added automatically as well. Is there a wildcard, special character, or script that will accomplish this? I'd rather not have to enter the number of pages manually as the value will change as these go through the editing process; I'd prefer to have the numbers update automatically. Has anybody done this before?

    Your first suggestion is the only way to capture the last page of a book that's comprised of independent document files. The last page number text variable works only within a single document.
    Anyone who wants a last page in book text variable badly enough can post a feature request at Wishform.
