Storage of new subject lines in sight at the time of validation only

(Text box) before the Date (text box) (Add button)

Request number Before Date of the front
(Label)(Label)(Label)Delete (button)
(Label)(Label)(Label)Delete (button)
(Label)(Label)(Label)Delete (button)


As you can see from the attached diagram. The user will be able to add new lines to the table (which is based on some ( view object). invokes the (Add) button action method of the bean class where he create new line and register the (before) and (before the Date) inside.) (Application number) is the value generated automatically, BUT this isn't just the sequence number, it is a combination of several component generated from the other entries of the user and that they are not displayed in the picture.

Problem is the (request number) could be changed based on user input, I don't want to store something in the view object unless (application number) is to finalize which is only when (commit). So, I do not want to store the new lines in the view object and I already know that they can change.

So I think in a way to have the same User Interface i.e Table and towing boxes but they are not mapped to a view object. So, what I need is a temporary space to store these data and in the moment of validation I will store them in the object view where I'm sure that (application number) is finalized.

I use Jdeveloper 11 g with technology of the ADF.


Take a look at the transitional view object

The application state management

Simply store your lines for transient VO and change your attribute when you need. After that, iterate as VO and insert each line in some way (for example, by inserting the new line at non-transitional and validation of the call)

  • "Start new Thread" is absent most of the time

    I'm not new to Dell Community, however, I post here in desperation of shear.

    I consider myself a person of intelligence average and the average Visual acuity.  I did not understand why sometimes I see the link "Start new Thread" and at other times, I would not.  I thought that there are a few steps to find what I didn't know.  I thought maybe the few times wherever I found it, it was by an unknown action, that I had taken.

    This morning I wanted to see a poster of beginner in another forum of the community on this community forum.  I tried looking for information before giving it to the other poster.  I have spent the last hour looking for this and other tips from the top downwards, for the link to start a new Thread.  I even read the how-to Post wikii and came out of the magnifying glass.  I couldn't find these 3 words!

    Then suddenly, after looking the other boards and back here, these 3 words were in plain view.  It's the durnest thing I've ever seen.  Sometimes the link is visible and sometimes it isn't!  What can I do for a beginner to this community when I have used Dell forums for 2 years, is having difficulty posting?

    What is someone having the same problem?  Whatever the issue, I will be very happy when it is fixed, it is very frustrating and time consuming!

    Thank you.


  • When you print an email subject line is displayed at the top left, can I change it to my name?

    Changed computers & previously my name appears at the top left when I printed an email. Work in a large office, and all use the same printer, so now when I print an email its not so easy to find.

    Select E-mail
    File > print preview
    a window opens showing email print.

    Click on the "Page Setup" button
    Click on the tab "margins & header/footer".

    Under "headers and footers".
    Click the first drop-down - menu and select "Custom... '
    by default it usually says "Title", which refers to the "subject".
    A small window will open allowing you to "' enter your custom header / footer text '."
    Enter your name and click OK

    The preview window is updated so that you can see the changes.

  • "No current line of sight" during the search.

    Dear friends,

    I have developed with a checkbox and lov OAF, the search box use
    Customizing auto search,

    Initially when using the query of the user checks the box, there was no application running even when
    There are data in the table, but LOV worked very well.

    In order to do so, enable the checkbox, I did the following things,

    1 ensure that you have entered the initial value, values controlled and uncontrolled.
    2 did not view instance and the name of the attribute.
    4 verified mapping transmitted between vo and the attribute box is correct.

    Now if I select anything other than the box, my query is not executed,
    Could you please share you thoughts,

    Thank you
    Keerthi.k

    Salvation had,.

    It's just a data integrity error.
    Make sure that the column to which your using the box check should have or the other value in each record so that even you uncheck or check out will be one of value and, LOV has no effect on this.

    Thank you

  • So, most of the time Thunderbird opens only incoming messages with a double click in a new window, which I find infuriating is there a workaround or a fix for this solution?

    At the start of Thunderbird, it opens the mail entering the lower panel with one click. But after an hour or two that no longer works and I have to double-click to open the message that is sent in a new window.

    Looks like a bad add-on for me. Now restart the SHIFT key and see if the issue arises again.

  • All new Satellite Pro L300D crashes all the time

    Hello

    I'm a little base when it comes to laptops.
    I just bought this new L300D to ebuyer

    I started and I have an anti-virus etc. But without apparent reason, the computer crashes.
    The only way out is pressed the switch out. Everything is frozen.

    It will do about 2 times and then after restarting it seems to work ok.

    I got windows to its original by HARD drive recovery settings and it did make a difference.
    I am as I say not a computer wizz.

    Can someone tell me how I can stop it crashing, it's really annoying.

    Kind regards
    Michelle

    Hello

    Does this happen often?
    I mean that the Windows operating system could break sometimes without any serious reason, sometimes a software compatibility issue might be the reason why the OS freezes.

    But I have this problem would fall so I recommend you contact an ASP in your country. It could be related to defective material

  • Errors on the creation of a new subject in RH9 (9.02 Patch)

    Have found that when you create a new topic in RH9 project on the mistakes of 3018 and 3111 of the construction project are presented.

    Seems that the error is caused by the introduction of Page break in the word document to the entry into force of the subject.  Earlier versions of HR would insert a new topic as well: - (Note correct placement of the Page Break and "Keep with next" a paragraph mark).

    Capture1.jpg

    When you add a new topic now, it appears as such: -.

    Capture2.jpg

    Note that the positioning of the "Keep with next" paragraph mark is now at the beginning of the subject line, rather than at the beginning of the page break.

    On the construction of project with a subject in this format causes 2 error messages additional that will be presented assistant error: -.

    1 HC3018: WARNING: in the project file, an #include statement is specified without a file name, and

    2 HC3111: warning: this topic contains keywords but Untitled

    The second warning (HC3111) is returned despite the properties of the topic containing a title, keyword sections and correctly filled.

    I found the work around to this problem is to correct the HC3018 error first of all in: -.

    • Place the cursor at the beginning of the subject line preceded of the symbol #.
    • BACKSPACE to delete the "Keep with next" [brand of ph to a point where the mark is removed, position properties are removed the title of the topic and the indication of Page break now extends across the page.
    • With the cursor at the beginning of the new subject line preceded by the symbol #, reapply the paragraph "Keep with next" command  This applies to the command on the "Page break" line.
    • Reapply the style of title to the subject line.  He's now looking at this line: -.

    Capture3.jpg

    • Re-build the project. 3018 and 3111 error messages now both disappeared.

    Yet another bug in this version doubt now.

    Here is the solution that I use:

    -Open Word Options for the document

    -Select "Advanced".

    -Scroll to the bottom of the list and select 'Layout Options.

    -Do scroll to the bottom of the list, and then search up to about 20 lines or so "Split apart page break and paragraph mark"

    -Select this check box and then click OK to exit.

    This solution came from a helpful Lady on the forum are a year back

    Would be nice if this could be defined as a default for new documents. I don't see how to do this.  Maybe somebody.

  • E-mail subject line in iOS 10, without a preview of the e-mail any...

    I use my phone for a large number of emails for work. I often get emails from myself of an automatic e-mail system. I have set up notifications to show me on the lock screen. But I don't need a complete overview of the emails. I prefer to see just the subject line. I can't understand a parameter to include the subject line which had before the upgrade. It just says: the senders name and the "electronic Message". Is there a solution to this or decides that Apple was not a necessary option?

    Also, I want to come back to be able to remove it from the lock screen without going to the first view. This is a step of unnessary simply delete e-mails that I know that I don't need!

    To my knowledge, that's all what you can do:

    Set notification preferences. Go to settings > Notifications. Tap on an application to set notification options. For example, choose to allow notifications from a specific application or turn on the sound on a notification, or turn off.

  • New AOL e-mail: one quarter of the screen is blank on the right side, reducing the space for the e-mail subject line. Resize attempts do not work on the right side, so I can't expand the e-mail subject line

    The new AOL E-mail look, which yesterday began a quarter of the screen is blank on the right side, thus reducing the space for the e-mail subject line, which limits its usefulness. Resize attempts do not work on the right side, so I can't expand the e-mail subject line? Running XP pro and Mozilla Firefox 5. No problem with I.E.

    Thank you, these settings were already in place. AOL said now erase the cache, cookies and history... to solve, which worked. (I deleted the cache and a story time.)

  • Check if a subject line of view is new?

    Small question about ADF BC 11.1.1.2.0:

    Is it possible to check whether a line in my display object is new? (by 'new' I mean not yet stored in the database yet). Maybe I should check the line of the entity, not the line of sight, if yes, how to do hand on the line of the entity?

    I have a form that allows users to add additional values in a list of values. When they finally support the form I need to delete all the lines that have been created by the user but not used. If the user does not finish using an any of them, I need to delete them all.

    Any ideas?

    See you soon!

  • Can I change the subject line of a message or add a note for my reference?

    I'm still new with tuberculosis after using Outlook for years. In Outlook, it was possible to change the subject line, even though the content was lock. It was nice to put the content in your context, a note, etc. You can do this in Thunderbird or is another way to add a note?

    I think that the Add-on EditEmailSubject would add the functionality you want.

  • TB 31.5.0 Win 7 after the TAB key for the automatic update no longer creates new address line "write" (enter the done key) but I want the TAB key! Why this keep happening after

    TB 31.5.0 Win 7 after the TAB key for the automatic update no longer creates new address line "write" (enter the done key) but I want the TAB key! Why is - this seems to happen after each automatic update? Cant we get 'option' to use the TAB key to navigate through the lines of address "write"?

    TAB through the fields that exist. It is the function of the TAB.

    Otherwise you could never use TAB to go out in a field for example: subject. It would create an indefinate number of fields and are unable to function as a TAB key.

    TAB does not back to THE fields,
    New crests to THE fields or donkey typing/selection enter/return address, you can use the selection of mouse click.
