disable the value change listener until the previous process is complete

I use Jdeveloper 12.1.2

I have a text field that has a value change listener. The listener calls a function that manages a number of process and queries. The function then clears the text entry field and focus the cursor in the text entry field.

My problem is that the user will enter the text back to back quickly it causes all locked up. Is anyway to prevent the user to enter additional text before the end of the listener.

I tried the following, but he has not always prevented the user. At the beginning of the listener:

FacesContext facesContext = FacesContext.getCurrentInstance ();

UIViewRoot root = facesContext.getViewRoot ();

InputText RichInputText = (RichInputText) root.findComponent ("it4");

inputText.setDisabled (true);

AdfFacesContext.getCurrentInstance () .addPartialTarget (inputText);

then at the end of the listener, I re activated the field.

inputText.setDisabled (false);

AdfFacesContext.getCurrentInstance () .addPartialTarget (inputText);

Maybe this can help: http://www.jobinesh.com/2010/10/preventing-user-input-on-fusion-web.html

  • Impossible to trigger value change listener for a checkbox custom AF: table

    Hi all

    IAM using Jdev 12 c.

    I have a created a table and a list bound to the table. The values are perfectly filling. I added a checkbox as another column. All select/deselect the box, no event is triggered... Please find below the the code I used.

    JSPX code binding the table and column checkbox

    < af:table var = "row" rowBandingInterval = "0" id = "t1" binding = "#{EmployeeTableList.empTable} '"

    contentDelevery value = "#{EmployeeTableList.empList}" = "immediate" > "

    < af:column sortable = "false" headerText = "EMPID" id = "c1" >

    < af:outputText value = "#{row.empid}" id = "ot1" / > "

    < / af:column >

    < af:column sortable = "false" headerText = "EMPNAME" id = "c2" >

    < af:outputText value = "#{row.empname}" id = "ot2" / > "

    < / af:column >

    < af:column id = "c8" headerText = "Select" >

    < af:selectBooleanCheckbox label = 'Label 2' id = 'sbc2' autoSubmit = "true" value = "false".

    valueChangeListener = "#{EmployeeTableList.newlyCreatedMethod}" / >

    < / af:column >

    I tried the javascript also, but not luck at all... If you use IAM table datacontrol and adding a column of the box... value change listener is triggering perfectly.

    Please help me. Thanks in advance.

  • How to disable the export process

    Hi guru

    We have an FDM application that requires some places only proceed in what concerns the stage post. We want a simple method to disable the export process.

    Sites meet this criterion place within specific control groups and have specifically formatted place names which makes it very easy to registering via the script. For example, all this fine location with '_PADJ '. A preliminary event to the export script can test and trap this condition but I can't find any mention as to how the export process that was started can be terminated through the API.

    Any advice greatly appreciated

    Create a second target adapter and assign it to those places. Under the integration of this adapter settings, uncheck the option 'enable the load '.

  • Re-installing the new formatted disk. How to disable the previously installed service CS6 Master Collection?

    Welcome.

    I had my whole CS6 Master Collection installed and active with the Adobe servers - primary disk but is dead.

    Now, I have a newly formatted with a fresh install of Win7 on this drive. I would like to re - install my entire collection CS6 again.

    As far as I remember, you must DISABLE all our software installed PRIOR to the activation of any new facilities?

    If so, since I have not disable the software of my dead drive (which I can't access now anyway) - how can I disable it now? I don't see any option to do it on my online account.

    Can someone advise please.

    If a Customer Service Rep is reading this - can you be please DISABLE all my CS6 Master Collection software - please so I can reinstall again.

    Thank you very much.

    You should contact the Adobe Support via chat and ask them to reset your activations - you will need the serial number.

    Chat support - the link below click the still need help? the option in the blue box below and choose the option to chat...

    Serial number and activation support (non - CC) chat
    http://helpx.Adobe.com/x-productkb/global/Service1.html ( http://adobe.ly/1aYjbSC )

    You are allowed to have two facilities enabled, so if you wait for the week to get their attention, you can install and activate as long that you had only activation one used so far.  When they reset the activations you can reactivate again later (or turn off the new one yourself before chatting with them).

  • Pass a value change listener to a declarative component

    I use JDeveloper 11.1.1.6.0
    I am able to create my declarative component, but I need the ability to switch in listeners of different value changes depending on where the component is used, and sometimes I need to have no value for the component change listener.
    Currently, I tried to get the element with an attribute "ValueChangeListener' of type 'javax.el.MethodExpression' and gave the EL method in the method that handles the value change events. However, whenever I run the application, I get the following error at an event for change of value on the component. It acts as if I am the EL of passage is empty, but I do not understand why. I approach this issue the correct way or is there another approach recommended for this? If I approach it as expected, I have help to determine what I am doing wrong?

    Hello

    In JavaServer Faces, components raise events to notify the application of a change or user interaction. The declarative elements in Oracle JDeveloper 11g allow the component developer spend events and actions of the method to the page of your. A method's return type and optional arguments that are passed to the call. On the page of your, ExpressionLanguage is used to bind the method property of the component to a managed bean with the expected signature method.

    If you create a method attribute (method tab) and click the button [...] in the field of the method Signature. Define the return 'null' and the parameter type of method like "javax.faces.event.ValueChangeEvent" then you can set up a change of value for her listener in the consumer application

    So what you did is simply not the right approach

  • 11.1.2.3 JDEV get the selected value of RichSelectOneChoice at the bean (but not in the value change listener)

    We have implemented our own listener of downloading files to export the table data in Excel. The reason for this was that we did not want certain columns to export.

    We have the collectionmodel table. All columns have been extracted from the table and for each column the value inside the component was read and written in the outputstreamwriter.

    Now the problem is, we have a few selectonechoice fell in the columns of the table read-only. For components, it exports the data that the index selected and the value selected.

    Is it possible that I can get the selectedValue of the component of type RichSelectOneChoice in the bean?

    We use Jdev pointers 11.1.2.3... Any are appreciated...

    Found the solution. Add LOV VO as iterator in a combination to page and access it as below... use index that selectonechoice.getvalue returns as well as the name of the iterator.

    BindingContainer links is BindingContext.getCurrent () .getCurrentBindingsEntry ();.
    DCIteratorBinding dciterContainer = (DCIteratorBinding) bindings.get (iteratorName);
    Ri rank = dciterContainer.getRowAtRangeIndex (index.intValue ());
    String val = (String) ri.getAttribute (attrName);

    I have this job except that I don't know how I can disable the entire page and see an hourglass.

    I have to use Javascript for this?

    Hello

    I've had this work now after the use of clientListener as below.

    Binding = "#{backingBeanScope.backingBean.IT1} '"

    ID = "it1.

    valueChangeListener = "#{backingBeanScope.backingBean.checkUnique} '"

    autoSubmit = 'true '.

    Validator = "#{backingBeanScope.backingBean.validateDeptName}" > "

    Type = "valueChange" / >

    Thanks for your help.

  • value change event not called on the evolution of the value falling down


    Hello

    I have a drop down with values such as... 1-25, 26-50 and so on.

    I need to see the 1-25 as pre-selected when the page is loaded. and when we change the value in the drop down a listner valuechange is called and will service call.

    But when I again selects the default 1-25, at the time where only the value changes listner is not called.

    To show the value that pre-selected I put:-noOfRecSOC.setValue(1);

    noOfRecSOC is the drop down on the screen.

    You must not directly set the value in the UI component. Use the property value drop-down list together for years by default here. Otherwise the value change listener do not notice the change to the original value (as it is never changed).

    You can use a variable temporary pagedef for the value. check out my blog Creating Variables and attribute Bindings to Store values temporarily in the PageDef | JDev & amp; ADF Goodies to find out how to do this.

  • AF:inputComboboxListOfValues selected value indicates the previous value when read

    Hello

    I have a LOV as below.

    SELECT DISTINCT filter_prod_id, cis_cluster_config_hdr_dtl_vw WHERE cluster_type_id = prod_name: p_cluster_type_id
    AND type_criteria_id =: p_type_criteria_id order of prod_name

    Here prod_name is indicated in the attribute list and based on the selection, corresponding filter_prod_id is filled. I use af:inputComboboxListOfValues in the JSPX page. By default the the LOV is filled on the loading of the page. I have a valueChangeListener and AutoSubmit is set to true.

    Use case: tell the current selection in the drop-down list box is 'CHAIN '. Change the selection in the drop-down list of "3rd PARTY GIFT CARD" area. I have a productNodeSelectionChangeListener() method and here's the code.

    BindingContext bctx = BindingContext.getCurrent ();
    BindingContainer links = bctx.getCurrentBindingsEntry ();
    List JUCtrlListBinding = bindings.get ("ProdName") (JUCtrlListBinding);
    String prodName = (String) list.getAttributeValue ();
    System.out.println ("ProdName:" + prodName);
    FacesCtrlAttrsBinding list1 = bindings.get("FilterProdId") (FacesCtrlAttrsBinding);
    Number of filterProdId = (Number) list1.getAttributeValue ();
    System.out.println ("filterProdId:" + filterProdId);

    The code prints

    IN productNodeSelectionChangeListener CARD PART 3
    ProdName: STRING
    FilterProdId: 79

    Help, please.

    ValueChangeListener is _before shot phase UpdateModel.
    However, you can force the update of model the value change listener:

     public void your_VCL(ValueChangeEvent event)   {
            UIComponent c = event.getComponent();  
    
          //force update model phase for this component
          c.processUpdates(FacesContext.getCurrentInstance());
         // what happen when you try to get attribute value in this point ?
    
      }
