How to set the initial value of the same value as the Page loading of SelectOneMenu

Hello

I noticed that in my value = "#{bean.selectedItem page}" of selectonemenu is always null when loading the page and because of that there is a difference in the initial value and the value sent as valuechangelistener is shot because of this difference, I don't want to happen. "

I call the method to load the values into selectonemenu in the constructor of my bean.

How can I make sure that the initial value is always the same as the value at the time of page load so that valuechangelistener would not fire unless the user changes the options in selectonemenu. Because of this problem I am facing a lot of issues like valuechangelistener is going to get fired.

Any help is much appreciated.

Thank you

Yes, you will need to find a way to set the value before the creation of the part of the view. Generally, there are two ways. There are at least two ways, I tend to use:

(1) loading deferred; you would get a Get accessor like this method:

public String getValue(){
  if(value == null){
    // code here to get value from wherever
  }

  return value;
}

(2) initialize properties in a method annotated with @PostConstruct in your backing bean

@PostConstruct
public void initialize(){
  value = whatever;
}

Hope that helps you. If this isn't the case, so I totally misunderstood you and you try to explain more clearly what your problem is.

  • How to set the page template for a page in app

    I've been looking for a way to re - assign a specific page to a different page template, and I must be blind. I did it with the regions and reports, but never a whole page. The closest I can find is how to set the default page for an application model template. What I have is a printable form that they want in a specific format. I was able to code the whole thing into a region of PL/SQL, but I was hoping that I could take an existing page template and modify the model to different regions in the areas I would like to.

    Can someone help me find this? I have already created a copy of the page template I want to twist.

    If you are in the tree view, double-click the entry of title of page (top); If you are in the component view, simply click the edit button in the page area. Either way will take you to the screen of the Page change. in the display attributes section, you will see a Page Model drop-down list.

  • How to set a default value for a page element

    I work with an array of facilities that has the name and the address. The user can add information to the contact person on a separate page. Because the address of the establishment and his contact is generally the same, I want to add a default value to the contact address. The installation page is on 201 and the link to add a new line of contact is on page 202. I showed in the default value: P201_street to the address of the contact. But, when I run the page, contact the address field shows the: P201_street, not the address of the actual plant. Do I leave? Must be something obvious?
    Thank you very much.

    Hello

    Use: P202_STREET1 for PL/SQL expression, or just P202_STREET1 if you use the value of the item condition.

  • How to set the page background color

    I would like to create a book with blank pages, some gray and some black backgrounds.  In photoshop, it's easy to set a background color, but I don't see how to do this in InDesign CS4.  It should be easy, but I can't find the answer anywhere!

    Thanks for your help.

    Paul

    Unless you intend to actually print the background color, rather than printing these pages in stock color, you should put a layer of sepatate behind everything and be together the nonprinting layer or turn off the visibility before the release.

    In addition, if the majority of the publication will be released on colored stock, you can change the shade [paper] to show something close, so you will not need to have a special background for these pages.

  • How to set the value of a variable in a cluster in LabVIEW to c#?

    Hi guys, I'm working on a small c# program, which by using the interface provided by LabVIEW.  And I know that, with the help of lv. SetControlValue (name, value) can set a variable just on the front panel. But in my case, there are several groups on the front panel. Then it confused me how to set the variables in these groups. For example, there is a cluster named clusterA and a variable named a., I tried something like this:

    lv.SetControlValue("clusterA.valueA",1);
    

    but it totally inoperable. Everyone has some experience with this sort of thing? Thank you very much!!

    Hey guys, thanks a lot for all your response. I just found a simple way to solve this problem. For example, there is a cluster named "ClusterA", and there are only two witnesses, who are: an int value named "IntA" (default = 10 IntA value) and a string value named "StringA" (by default the StringA = 'abc'). In c#, if you call the method:

    var clusterA is vi (Array). GetControlValue ("ClusterA");

    you will get a table looks like: clusterA = {10, 'abc'}; So if you want to change IntA 123, you simply do:

    clusterA.SetValue (123, 0); 123 the value, 0 is the index of IntA in clusterA, after this clusterA table = {123, 'abc'}

    After that, simply to make the table in LabVIEW using:

    VI. SetControlValue ("ClusterA", clusterA);

    and now you see the LabVIEW, IntA is changed.

  • How to set the value of adjecent record

    Hello

    For an interactive report, I wanted to know, how set the value for one of the value column taken recording (the visible record in the report) adjecent to the same column in the current record.    The reason behind this requirement is, the table contains cirtain ID which is populated based on cirtain condition.  And the same ID must be set to adjecent different records.  Since this is event based on human evaluation of the data, I can not run the UPDATE command in the background.

    To simplify the requirement, suppose, report IR on the employee.  Based on the user, click one of the dummy 'comlumn link', the value COMMISSION_PERCENT must be copied to the next record.  If I know EMPLOYEE_ID value of the next record, then update SQL will do the job.  But how?

    Thank you

    URL: javascript:void (0);

    2. edited Page attributes

    Under run when the Page loads

     $("a.cpycomm").click(function(){
        var $el = $(this);
        var nextemp = $el.closest("tr").next().find('td[headers="C725254625175515007"]').text();
        var comm = $el.closest("tr").find('td[headers="C725255480705515009"]').text();
        $("#P1_EMPNO").val(nextemp);

        if (confirm('Copy Commission to next record ?')) {

  • How to set a default value in the Import Wizard delimited for the date?

    Hello community,

    I am currently trying to import some files delimited in a SQL table via the Import Wizard (right-click on a Table "import data... ") with delimited as input (.dsv) files.

    In step 4 of the wizard, I put the columns in the Source files for the target of the columns of the Table.

    Now, this is where my problem. Whenever a target column has the format "date", I define the mask of translation you want for each column.

    I would like to define a mask by default so that the same format is always used.

    User interface, it looks like this field also exists:

    field_greyed_out.png

    However I can't put it in the wizard itself, and I'm not able to find the option in the preferences.

    I tried the following preferences (Oracle SQL Developer 4.0.2):

    Preferences-> database->-> all NLS date 3 preferences set to "HH24:MI:SS DD. MM YYYY ".

    Preferences-> Migration-> translators-> Format of Date Source default value "HH24:MI:SS DD. MM YYYY ".

    Preference-> Migration-> data move Options->

    DataMove.PNG

    But still, I have to type it every time.

    Can someone explain how to set the default value?

    You can not.

    But.

    In the next major release, we seek to:

    • selection of a menu selector common date formats drop-down
    • Save your import settings session and their reloading for later import

    I think you have a good idea, maybe it defaults to MRU. When we start the process of the Beta/early adopter, be sure to check and let us know what you think. For the moment, and what I'm doing, I copy the date format string and paste them in such as required. I'm not a super big fan of having default values in 'automatically' added because it can lead to mistakes, and in this case, data corruption issues.

    Concerning

    For the date, you can use groovy expression adf.currentDate to set the current date. reference http://adfgouravtkiet.blogspot.in/2012/11/how-to-set-default-values-for-entity.html

    You already have ways to use the sequence.

    How do you add a new value in the form. You're creating a new line of your page (user interface) and by engaging with validation operation? Unless you commit you will not be able to see anything in the table.
