Component interface user can be linked to multiple Beans? 11.1.2.3 Jdev

Hello:

An interface component user can cause links component to multiple beans? If so, how?

Example:

I have a component of existing (af:outputText) that already has a binding component to a bean existing UI.

Bean another I need a handle for this same component so I can refresh it with adfFacesContext.addPartialTarget)


If I bind this component of the second bean, I think it would be to cancel the binding of the first bean.

A component can be exposed to two different grits?

Thank you very much.

No, you can't do this and you should not do this. However, you can either search the component view using findComponentById (http://adfcodebits.blogspot.ch/2011/12/bit-32-locating-component-on-client.html) or do you get the other beans and ask the other bean to get you the part.
To access the other bean, you can use

  /**
   * Method for taking a reference to a JSF binding expression and returning
   * the matching object (or creating it).
   * @param expression EL expression
   * @return Managed object
   */
  public static Object resolveExpression(String expression)
  {
    FacesContext facesContext = getFacesContext();
    Application app = facesContext.getApplication();
    ExpressionFactory elFactory = app.getExpressionFactory();
    ELContext elContext = facesContext.getELContext();
    ValueExpression valueExp =
      elFactory.createValueExpression(elContext, expression, Object.class);
    return valueExp.getValue(elContext);
  }

and pass the EL as "#{xxxxyyybean}" as parameter, where xxxyyybean is your component is bound. You may need to add the bean is in the scope.

    When you select date in chooseDate in the homepage, he got passed as an input to the flow of the area/task parameter, and the region is updated.  I can see in < af:outputText value = "#{pageFlowScope.backing_cmCalBean.activeDay}" id = "ot4" / > in the region that it accepts the parameter correctly from the home page and in the region got refreshed. "

    However, there is a panelGroupLayout in the region which is built programmatically in the bean based on the input parameter

    < af:panelGroupLayout layout = "scroll" binding = "#{pageFlowScope.backing_cmCalBean.cmCalPanelGroupLayout} '"

    ID = "pgl37" partialTriggers = "cil3 cil4 cil2 cil1" >

    I can see in the paper that the methods in the bean got called correctly and that is the construction of the panelGroupLayout with the right data.  But she has not updated and reflects the new data in panelGroupLayout.

    I have even in my bean code: delete children panelGroupLayout before strengthening again on the update.

    If (cmCalPanelGroupLayout! = null) {}
    LOGGER.info ("claire cmCalPanelGroupLayout");
    cmCalPanelGroupLayout.getChildren () .clear ();
    }

    Any ideas how component user interface built by program in the region can get updated then the outbreak of the homepage?

    Please notify.

    Thank you

    -Mina

    I found the solution.

    You will need to disable the children in the region, a single layer, instead of just compensation to the children of cmCalPanelGroupLayout:

    Region of RichRegion (RichRegion) = JSFUtils.findComponentInRoot ("r1");

    region.getChildren () .clear ();

    AdfFacesContext.getCurrentInstance () .addPartialTarget (region);

  • Facing problem while in place emphasis on the pop-up component interface user

    Scenario-

    I have a jsff page.

    On the page, I have a button and a pop up

    When you click the button, pop up comes with 10 text entry box. By default, his shows on the first field accent, but I want it to be on the second text box.

    I already have a client component to TRUE for the two input as well as pop-up text

    Hi guys,.

    I found the solution,

    I changed my customer contact on af:pop - up to earlier that I was calling from button makes part of the same page and he called client listener first and then pop up.

    If my goal is not to set to pop - up field.

    So now I'm able to get the focus on the pop-up field.

    Here's the code.

    function setFocusOnAccount(event) {}

    Alert ('Hi');

    var component = event.getSource ();

    Alert (' component name ' + component);

    var characterCounter = component.getParent () .findComponent ('pt_it2');

    Alert ('characterCounter with Parent' + characterCounter);

    characterCounter.focus ();

    }

    contentDelivery = "lazyUncached".

    popupFetchListener = "#{backingBeanScope.bannerFlowBean.searchPopupClearFields} '"

    popupCanceledListener = "#{backingBeanScope.bannerFlowBean.resetPopUpFields}" > "

    To access the Options of process definition page, select selectPeopleTools, and then selectProcess Scheduler, then selectProcesses, then selectand click on the Options tab of the process definition.

    Image: Definition of process Options Page

    This example illustrates the fields and controls on the Options of process definition page. You can find definitions for fields and controls later on this page.

    Security process

    Go to the Security section of process.

    Process group

    Make the process definition a member of the group. A process definition can belong to several groups of processes.

    Select an existing group, or add a new group by entering a single process group name. To add new lines, click the Add button.

    Process groups are then assigned to profiles of security administrator Security in PeopleSoft, which allows you to specify process queries the user classes can perform.
    See PeopleBooks:

    Setting permissions of process

    Access to the whitelists - process page (select selectPeopleTools, then selectSecurity, then selectPermissions & roles, then selectPermission lists and click on the processes tab).

    Just as you set permissions for pages, a user can access, you must also specify the batch (and online) process that can call users through PeopleSoft process scheduler. In general, process groups are classified by Department or task. For example, batch programs used by your payroll probably all belong to the PAYROLL process group, or a group named the same way.

    When you create a process permissions list, you add the groups of appropriate process so that a user belonging to a particular role can call the appropriate batch programs to complete their commercial transactions. To do this, use the process group permissions page.

    The process authorization profile page allows you to specify when a user or role can modify certain parameters of the PeopleSoft process scheduler.

    Note: You grant process profile directly to the profile user and group permissions of process through whitelists.

    Process group permissions

    Access the page process groups (click on the permissions link on the whitelists - page process process group).

    File: Page permission to process group

    This example illustrates the fields and controls on the page of the authorization to process group.

    This page lists the groups of processes associated with a permissions list. Process groups are collections of process definitions that you create using the PeopleSoft process scheduler.

    As a general rule, you group process definitions by groups of work within your organization, and this working group usually has a particular role that is associated with. No matter how you organize process definitions, you must assign process groups to a permissions list.

    Users can run only processes that belong to groups of processes assigned to their roles. For example, you can have a set of process definitions that relate to your human resources department and another set for your production service.

    In other words:
    Add the process to the runcontrol component, providing the user access to the runcontrol component.
    Add process group processes. Add process group to the permissions list. Assign the authorization list to user.
    Hope that answers your question.

  • Content in the interface user of ADF

    Hello

    the content component to create links between content items.

    Anyone know if it is possible to use the content related interface user ADF component?

    TKS.

    To my knowledge, it is not possible - in fact, not even in the current version of the 12 c.

    However, you will need to move to 12 c in the future to get this.

    See http://docs.oracle.com/middleware/1221/wcc/WCCAA/GUID-6CF263BB-58E9-4A12-A309-AE28C70BC578.htm#WCCAA2260 for more details.

  • Dynamic tab Interface User Shell - close the tab action &amp; number of open tabs control

    Hello
    I browsed the forum, but could not get their hands on a concrete solution to the issue on how to capture the event action to close the tab and perform an action on this?
    The thread below about my question, but doesn't seem to have a good solution
    Re: Dynamic tab Interface User Shell: control icon close

    And another question, currently in the TabContext the number of open tabs is at the limit of 15. How can I replace only such that I do not allow more than 7 tabs open at the same time?

    Please help me with the two queries above. Thank you!

    Kind regards
    SS

    Sorry for the delay so much. Finally got some time to play with the model and by downloading the source code for dynamicTabTemplate and substituting the closeIcon worked like a charm.
    Let me summarize what I did to help someone who is looking for it :)
    (1) download the source code for dynamicTabTemplate
    (2) added and additional attribute to the model closeTab
    ++
    +closeTab+.
    +java.lang.String+.
    ++
    true
    +    +
    +    +
    (2) the dynamicTabShell.jspx edition, closeIcon commanlink actionListener to be linked to the "#{viewScope.tabContext.closeIcon}".
    (3) implemented the method of closeIcon in TabContext
    +@Override+
    + ' public void closeIcon (ActionEvent actionEvent) {+
    CloseIconInterface bean = getBean().
    bean.closeIcon (actionEvent);
    +}+
    (4) generated the jar.
    (5) delete the oracle supplied jar dynamicTabTemplate by default and instead added my custom pot generated on demand
    (6) implementing the new model
    (7) set all attributes with attribute closeTab. It would take the name of BackingBean... example:
    (8) xxxBean done to implement CloseTabInterface
    (9) implementation of the method closeIcon with custom code to confirm the page close prior to removal of the tab.

    However as you say, I will keep tab on the future updates of the default model tab updates fail bug fixes or improvements.

    Thanks to all those who have looked into this for me and I hope this helps someone else :)... Good luck!

  • A challenge: combining dirty tab Interface User Shell + self-closing-BTF

    I find it difficult to use the facilities of the shell of the interface user ADF of the conduct of the stubborn self-closing-standalone task.

    What the Shell of the user ADF interface does well: in the Shell of the user interface, you can open a standalone BTF as an activity, and if the BTF closes itself (that is to say... given the user selects ok or cancel/close button, the BTF stand-alone navigates to a special return flow option), the BTF closes and the ADF UI Shell correctly closes the tab around the activity.

    My challenge is that I want to add installation tab 'dirty' shell ADF of the user interface for the task force, such as if the user inside the BTF selects a custom cancel/close button (not the Shell UI button close tabs) that accesses the task-flow-back option in the Working Group, they had the chance to confirm or cancel the closing via the ADF UI Shell dirty tab popup. (Note that task-flow-return options are crucial to BTF to self-latch because they not only allow the BTF of commit / rollback, as well as make them re-entering or playing with the functions of backup point).

    If the ADF UI Shell shellLauncher Bon we call method makeCurrentTabDirty on the opening of the BTF, activity of the BTF tab is italicized properly. Even if the user selects the BTF Cancel button, the BTF farm (she disappears in fact from the Shell of the user of ADF interface) but the Shell of the user activity tab interface is still visible, then watch the dialogue dirty tab, which is too late, the Working Group has already closed.

    So my solution is when the button close down BTF, before he navigates to the BTF task-flow-back option, I can get the ActionListener to the button close BTF to trigger an event that is contextual to the shell of the user ADF to capture interface "shut up" occurrence. The Shell of the user interface then has a chance to show the dirty tab dialog box by capturing the contextual event.

    Then, my sticking point is the class TabContext provided in the Shell of the user interface has no way to call the dirty tab dialog box without calling the removeTab method. It is not desirable for the Shell UI close the BTF as task-flow-return of the BTF activities must always be called... remember that they have an additional feature that is required for the BTF.

    Even if the TabContext method is a solution to display the dialog box dirty tab without closing the tab (TabContext is pretty easy to extend yourself if you have the source code), the problem to which I can't think a solution is, how to get the tab dialog box dirty to communicate with the BTF stand-alone version (yes/no) result such that it can take a decision on the abandonment of action close and let the user on the current page fragment, or accessing the task-flow-return node?

    We could suggest that I could expose the dirty to the BTF stand-alone tab dialog such that she could show the dialog box confirm himself. However the point being is the BTF is autonomous and should have no knowledge where it is used, in the Shell of the user interface or some other supershell application. Publish plans to close the BTF via a contextual event seems fine, but alternatively of loading in the components of the interface layer user seems to break the independent principle I-don't-know-or-care-about-what-my-parent-caller-is-doing BTF appears on the border of evil.

    Anyone pointers, suggestions or comments like you're-an-idiot-Chris,-do-it-this-way? Your help is appreciated.

  • How can I do a multiple selection in Enum control or control of the ring or control Combo box

    How can I do a multiple selection in Enum control or control of the ring or control Combo box

    You can not.

    You can use a listbox control.

    An alternative solution is to write the code and each selection, the user gives an enum, for example, can be send to a table and invite the user to continue to select...

  • How can I display table 2D tabular on the Panel before the user can delete any subdashboards

    Hi guys and girls.

    It is my first post here, so go easy on me. I promise you that I used my best GoogleFu I before posting here.

    I am a self taught amateur LabView. I worked on a User Interface for my Robot SAGAR. See some of my work so far (girlfriend used as a draft classes, but we have both worked together on it, which got hooked me in the first place on LV):

    Now, I'm working on the use of LV and Google Earth as a planner of mission right now.

    My question is this. I have a 2D array that stores the Lat/Lon each waypoint. I's like to have posted on my

    front tabular, with WP # (the 1st dimension array index), Lat and Lon on line, like this.

    More importantly, have the user can select a point of full path (or just the number of WP would be ok) and remove it using key DELETE or any other button on the Panel.

    I am at a loss on how to do it. Ideas?

    Thanks for the help!

    Heal the little robot.

    You said that you were using a table. I suggest using a multicolumn listbox. In this way, you can change the selection mode to "highlight the whole line. You can use a structure of the event to respond to the user by pressing the delete key. See attached simple example. Note that some keyboard can label the BACKSPACE key as 'delete '. If you want to answer it, you also have to see if the Char value is 8, which is the code for this key.
