How to assign components page parent of a page fragment in a dynamic region

Hi, I am using JDeveloper 12.1.3. I have a single page request that contains a sidebar (with separator) on the left and a dynamic region on the right. One of the fragments of the page that appears in this dynamic region has a task flow that calls another fragment of page. What I do when this event occurs, it is to dynamically hide (or at least close) the left side panel. I created a bean of support that includes a method to do so. This method works very well when I call it from a test button on the parent page. But I can't understand how effectively call it a method in my stubborn workflow (page fragment). I created the method and incorporated it in the workflow. I refer to the method in the bean support. No errors are generated when I perform the navigation. I have debugging instructions that indicate support bean method is called. But the screen will not reflect the changes on the side panel. I tried to use a parent action in my stubborn workflow (and tried to have this action relative to call the method), but that did not help. I thank you very much for any assistance, you can provide.

The problem is that you can reach the panelSplitter of off the page on which it is located. If you use a methodcall activity that you call with a parent action you get a new instance of the separator, but not then, you try to change.

What you can try to bind the separator to a property of bean a bean view extended who resides in the workflow of the parent page. Then you pass this bean as a parameter to the flow of the task of the fragment and call the method within the bean. It of called bean reference and is listed in this article by Frank Oracle ADF May / June 2013. Make sure that you use a component for the bean property reference. On second thought, you might not even to bind the separator to the bean as you can look it up in the page directly using findComponent().

  • Pass the parameter page fragment in a dynamic region

    Hello.

    I use Jdeveloper 11.1.1.3.

    Can someone explain to me how to pass the parameter page fragment in a dynamic region?

    My situation is:

    I have only 1 page: index.jspx.

    This page includes 2 items:
    1. < af:tree >
    < af:tree id = "t1" var = 'node' rowSelection = 'single '.
    value = "#{bindings." Rendering FpsrVO1.treeModel}"="true"expandAllEnabled ="true ".
    contentDelivery = "lazy" initiallyExpanded = "false".
    contextMenuSelect = 'false' fetchSize '-1' = >
    < f: facet name = "nodeStamp" >
    < af:commandLink id = "cl1" rendered = 'true '.
    actionListener = "#{backingBeanScope.RegionDynamicBean.treeClick}" >
    < af:outputFormatted id = "outForm' value = ' #{node." Name}' has made = "true" / >
    < name f: attribute = "Flash" value = "#{node." Code} "/ >"
    < / af:commandLink >

    < / af:tree >
    2. < af:region >:
    < af:region value = "#{bindings.dynamicRegion1.regionModel} '"
    ID = "r1" / >
    region could be changed to 3 delimited taskFows who have just a fragment of page.

    Can someone explain to me how I can send < name f: attribute = "Flash" value = "#{node." Code} "/ > element tree to page fragment that will appear on the screen?"

    You can move a card to the dynamic region that would take the parameters of workflow task in the form of key-value pairs.


    taskFlowId = "${backingBeanScope.TestPageBean.dynamicTaskFlowId}" "
    Activation = "deferred."
    xmlns = "http://xmlns.oracle.com/adf/controller/binding."
    parametersMap="#{backingBeanScope.TestPageBean.parameters}"/ >

    When reloading the taskflow, ensure that the settings are loaded into the taskflow.

    See this example from exactly your use case:

  • Default value loading the page fragment (jsff)

    Hello

    I use jdev 11.1.2.3.0 and I have an application that has a main page with links to launch fragments in a dynamic region.

    I use a session bean to populate the dynamic region

    One of the fragments has a selectoneradio control that is bound to a lookup table.

    The selected value is used to power a bean, who calls a stored procedure to create a record that is used elsewhere.

    I find that if you open the fragment and select one option other than the first item and go to an another jsff by clicking on a different link, then navigate back, still the previously selected item is selected, as opposed to the question that I would be default.

    I've been Googling away, but did not found a snippet of code that allows me to reset, or return to the first element in the set default control.

    Any suggestion would be appreciated.

    Yes, automatically send has been set to true.

    I found a solution to my problem, but it won't work for everyone.

    Because the list of items is linked, but the control itself doesn't have to be, I was able to set the default value directly in the value property of the control.

    Old code...

           
                               label = "#{bindings." SupplierSystemsLookup1.label}.
                               required = "#{bindings." SupplierSystemsLookup1.hints.mandatory}.

                               layout Binding = "#{backingBeanScope.SupplierChange.optSystems}" = "horizontal" "
                              

    inlineStyle = "margin: 0px 0px 15px 0px;" autoSubmit = "true" >

    New Code...

           
                               label = "#{bindings." SupplierSystemsLookup1.label}.

  • How to assign a value of the element from page to main page in the column element when Cre

    I have a form build on table T1. The T1 has a primary key defined (T1PK) and four other columns (C1 - C4). I have a form in this table. This form accepts the values of C1 to C4 and displayis an extra point, is not based on columns of T1 - P1_DUMMY. The form for T1PK element has the value "hidden and protected.
    When creating the form, I wanted that the value of the primary key (T1PK) will be obtained through existing trigger. I want to use the value stored in the page called "P1_DUMMY" for P1_T1PK.

    No matter what I do, I always get this error when I hit the button 'CREATE' on the page of the form:

    ORA-01400: cannot insert NULL into ('DEV'. "" T1 ". ("' T1PK")

    The Create button is a condition not to show if the the P1_T1PK page element is NULL. I created page rendering process, the process of transformation of page like this bock of PL/SQL:

    : P1_T1PK: =: P1_DUMMY

    But I still get ORA-01400. The form has the P1_DUMMY as display only, not not to store the State, so I can see that the P1_DUMMY element has the value I want (2).

    How to assign the value stored in P1_DUMMY in P1_T1PK when I click on the button CREATE on this form?

    Thank you for your time.

    The belief question is the way in which the calculation is being defined. You are not using the &. rating (dot ampersand) in PL/SQL and SQL.

    Try this.

    1 define the calculation on P1_T1PK of Type calculation of value of the element
    2. on the next page to load textarea, enter P1_DUMMY. No. colon or &
    3. give appropriate conditions

    Start by reading the documentation on elements of application.

    Go to the shared components > Application parts and create your G_FINANCIAL_YEAR item. Value Session State Protection Restricted - can not be set the browser so that the value is not editable by the user, falsification of URLS or scripts.

    On the home page, if there is not already a button to submit the value of the fiscal year, add one in the HTML area, with the Action as a submit Pageclick. Otherwise, you can do without the button and using submit Page in Page Action when the changed value select the parameter in the list so he can undergo.

    Then, in the section of the Page processing, create a calculation:

    Point Type: Application-level element

    Calculate Item: Application: G_FINANCIAL_YEAR

    Point calculation: After submit

    Type of calculation: Value of the element

    Calculation:

    Run the application, select a value in the list of the fiscal year and submit the page. Review of current session state in the viewer of session state by clicking on the link of Session in the toolbar developer. Select the Elements of Application in the view list, and then click set. The element of your application and its current value must be visible. You can now reference value throughout your application by using the appropriate syntax.

    You should also consider if a default value (for example the current year) using a calculation Application from the point of calculation on the new Instance and coordinate the application point and part of the homepage using point application as the Source of value or an expression with Source page element, the value always, replacement of value that exists in the session state.

    Thanks in advance

    Aalishan salvation,

    On your page, click "Edit Page attributes" in top right section of the Page. There, check the setting "Tab Standard Set" - it should point to the game of the tab you want to use.

    You can also check, thanks to shared components tabs, the tab itself to display the page number for your report in the context of the "tab Page" page

    Guy,

    The user is an administrator of the workspace: No.

    These authorisation schemes created by the access control wizard do not use status of developer/workspace user accounts. Must add user names in the apex_access_control table and assign the desired privilege to every user.

  • How to pin facebook page more from one person to the taskbar

    How to pin facebook page more from one person to the taskbar. Also if I get more a page pinned how can I change the icons to distinguish who is who. And how to pin the game I play on the who's who. When I try it pin Center apps, not the game.

    Hi Justin,

    I'm sure you know, the new taskbar in Windows 7 axes of apps.  Individual files or locations within these applications cannot be pinned as their own icon, but rather as options in the shortcut (right-click) of their parent icon list.
    With Internet Explorer 9, this functionality has been extended to allow Web sites to pin to the taskbar.  Note that there is a fine difference between site and Web page.  You can pin the whole site but not the pages of this site.  Similar to an icon for PowerPoint, then lots of different PowerPoint files on this right click on the list of shortcuts.
    An alternative is to create shortcuts to the pages and make them appear on the icon in the toolbar to IE.  To create a shortcut (rather than a "pin site"), you need to right click on an empty spot in the Web page and choose "create shortcut".  You will be asked if you want to place on your desktop, click Yes.   Then drag the new shortcut to your taskbar to pin it.

    I have a FORM on a table with two or three elements. How to assign values to the elements of the application with the values in the elements of form, every time the value of the element is entry, change or page is sent?

    I created a dynamic action to the region level with Event - change to run the suite of PL/SQL, I tried with 3 different ways in PL/SQL, as shown below, but it didn't work.

    BEGIN

    : APP_FY: =: P1_FY;

    BEGIN

    APEX_UTIL. SET_SESSION_STATE ('APP_FY', v ('P1_FY'));

    END;

    BEGIN

    APEX_UTIL. SET_SESSION_STATE ('APP_FY', v: P1_FY);

    END;

    Then I created an action dynamic at the ITEM level with change event to run the suite of PL/SQL and tried with PL/SQL, as shown below, but it didn't work.

    I need to assign values to the elements of the request form as these elements of the application will be used in many other pages in the application. How to I get there?

    Thank you.

    If a dynamic action of PL/SQL execution, you must send your list of page elements in the parameter "Elements of Page to submit.

    See the section 'run pl/sql' for this post.

    If the page is submitted, the elements of the page will be automatically set to session state, and you can have a page process make the code you have.

  • Automatic assignment of record parent registration RN when created by OPA and involve a custom object

    The question that we face, it's what seems to be the forced transfer of the child for parent records records when she is using OPA integrated with RightNow to create records. This scenario is a little complex, so I put try it below with a structure to make it easier.

    • Scenario: creating records in RightNow across an interview of the OPA
    • OPA setting of mapping:
      • Personal contact Center (account)
      • At the beginning of the interview, load data related to an individual: Incident
      • At the end of the interview, update Incident
    • Data models:
      • OPA: Global-> [object custom-1] > [custom object 2]
        • all containment relationships
      • RN: Incident-> 1-> object custom object custom 2
        • All relationships of association
    • Detailed description: in Takeovers we are inferring creating two records personal 2 object with a Custom single object 1. In these registers Custom object 2, we put directly the field that contains the link PK 1 custom, object so that each personal object 2 is actually assigned in RN for different Custom object 1s. Some examples of data to explain:
      • Custom 1 object associated with the Incident, read in the OPA
        • ID is set to 123
      • 2 custom object created in OPA under instance of Custom 1 object with ID = 123
        • Link to PK for 1 item 123-custom
      • 2 custom object created in OPA under instance of Custom 1 object with ID = 123
        • PK link for 1 custom object on 345 (different from the Custom object 1 read OPA)
    • Expected behavior: the object two custom 2s are created and assigned to their respective different personal 1 item RightNow records.
    • Actual behavior: the object two custom 2s are created and assigned to the Custom object with ID 123 1

    To continue the investigation, we then tested using a different set of objects, standard objects, but with the same rules:

    • Data models:
      • OPA: Global-> contact-> the incident
        • all containment relationships
      • RN: Organization-> (current) Contact-> Incident (custom object)
        • all relationships of association
      • Detailed description: same logic as the previous
      • Customer expected: same as previous
      • Actual behavior: Matches expected behavior. The Incidents have been correctly assigned to their two different respective Contacts

    This behavior of divestiture now seems specific to custom objects, but can ayone confirms that this is the case and the behavior expected please?

    In addition, we are confident that when you test this feature about 2 weeks ago, we received the expected behavior in BOTH cases to 80%. Maybe it's because changing the configuration in our RN environment that we are not aware of, so we are investingating cela, but are there changes to the OPA / connectors deployment for customer environments in recent weeks that could have caused this please?

    Finally, if this could be affected by a change of configuration of RN, nobody knows what this configuration can be please?

    I can confirm that this is the expected behavior. A few more details are given in the article of doco hierarchies entity Understand - he explains how the containment relationships mapped determines the assignment to the parent.

    The reason for this behavior is that most of the time, it makes sense that the registration of the new entity instances to 'work', feel that they are saved in exactly the same hierarchy of containment that was present in the OPA, and in a way that ensures referential integrity (we support in particular the case where the whole hierarchy of objects is created at the same time if the parent does not yet exist at the time of the creation of the rule (, so you couldn't possibly know its ID). Otherwise, as Matt says, is up to the author of the rule to make sure that, for example, 345 is a valid foreign key.

    This behavior should be the same for the built-in objects as well as custom objects, and as Brad says he has not changed recently. If you see this behavior in some cases but not in others, what this means is that probably in cases where it works as expected, there are multiple relationships between the parent and the child object, and it happens that the foreign key that you set manually is different from the foreign key of the mapped containment relationship.

  • How to assign a static IP (external) to a virtual computer when provisionng by vCAC

    Hi all


    I'm trying to figure out how to assign a static IP address at a request of vCAC via vCO prior to cloning. Without a static IP address assigned, cloning ends well and gets a random IP address... but I want the virtual machine to use a specific IP address.

    I use the pack of extensibility (not dynamic Ops Designer).


    Is it possible to do? Any ideas would be appreciated.


    Thank you.

    Are you planning on using network profiles for a pool of static IP addresses? If this is not the case, will provide you the IP address at the time of the request? For static IP address assignment, put in the property custom 'VirtualMachine.Network0.Address' and associated custom properties (see page 251 of the Guide) and if you have a comment specified in your plan customization, it will use this information to provide the IP address.

  • How to find children and parent of a resource in the HQU

    How to find children and parents of a resource in the HQU?
    for example, there is a server, how can I find all its services and its platform?

    by the way, where can I get a full HQU API doc? There is no description in detail in the Documentation of HQU:http://support.hyperic.com/display/hypcomm/HQU+Documentation

    Hello

    You can use the ResourceCategory.getPlatform () method to get the parent platform and you can use Resource.getViewableChildren () to the children. Here is a very basic example which comes out in the server.log:

    import org.hyperic.hq.hqu.rendit.metaclass.ResourceCategory
    import org.hyperic.hq.hqu.rendit.helpers.ResourceHelper
    imports org.hyperic.hq.authz.server.session.AuthzSubjectManagerEJBImpl AuthzMan

    def authzMan = AuthzMan.one
    def Overlord = authzMan.overlordPojo
    def rHelper = new ResourceHelper (overlord)

    def resource = rHelper.find (server: 12226)

    println ("" Resource: "+ resource.name +" is a child of ' + ResourceCategory.getPlatform (resource) .name + "and has children:" ")
    resource.getViewableChildren (overlord) .every child {-->
    println (child.name + "\n")
    }

    As far as documentation goes, what you see on this page is all that is available at this time. I use the code source HQApi as reference when I can't find anything in the docs.
