What elements of the page get included in the URL on doSubmit()?

It's quite perplexed me.

I have a page with 5 items on the page in a region in a table. All of them are hidden and protected.

The page is loaded with one of these items on the page specified in the URL.

If I use the button to delete one or more rows on the, or click on the button "Add new line", the page is submitted and returns with three of these five elements in the page specified in the URL.

First question: why only 3 and not all 5? Why THESE three? I see no difference between one of the page elements appear in the URL submitted from that which is not.

Second question: I've changed one of these page items to display conditionally. If a certain condition is not met, the field is never out of the page. However, EVEN THEN when I send the page using one of the buttons above, the field is included in the URL submitted! Should that even happen? That actually seems a safety hazard, unless there is something I am doing wrong.

I can probably create a test page to apex.oracle.com if necessary. (It of now on apex.oraclecorp.com, but move it will take time because I'll have to remove some sensitive data). But I hope that it is just some easy concept to explain, I'm just not grasp.

Thank you.

Hi Keith,

(1) check the branch. the branch defines what happened on the next page.

(2) Yes, this is the correct behavior. condition is for rendering, but the direction is fixed.

brgds,
Peter

  • How to pass the value of the element in the url

    Hello everyone

    I created a form using apex and in this form, there is that a button performs a redirection to a url

    212.12.233.63/WebSheetProjSite_2.1/SheetViewer.aspx? Mr =#P3_EVN_AF_PERSON_CODE #& sex =P3_EVN_AF_PERSON_Gender #& SheetCode = ERTS

    I need to get the Code of the person and sex in the url, but it does not work

    can someone tell me how can I do but it worked when I put the exact url in a report not a form

    Thanks in advance

    You must use a substitution in your target URL string, using & and. instead of #:

    212.12.233.63/WebSheetProjSite_2.1/SheetViewer.aspx? Mr =& P3_EVN_AF_PERSON_CODE. & sex =&P3_EVN_AF_PERSON_Gender. & SheetCode = ERTS

  • What element is the limiting factor?

    Greetings.  A previous employee in my company had set up a a universal station machine Instron who communicated with Labview via GPIB to test.  This station has served us for the last 6 years, but now we need to upgrade and I do not know what component to upgrade.  Sorry that my first experience with labview (other than by using the front of the GUI).  In the last days, I read the manual of Labview and it seems fairly intuitive.

    Pretty much all I want to do is read my load and position several times per second.  In reading the other posts and the manual, I was able to move the instrument I/O Assistant in a flat sequence structure and surround by two millisecond timers.  He confirmed that the I/O intrument Wizard is the limiting factor in the block diagram.  Currently, we receive readings on each ms 160-220 (it is surprisingly incompatible).  It is the same value I get timers.  I wish that the time between the readings more as 20ms or even 2 ms.

    Here's my system:

    LabVIEW 7 Express

    Windows NT 4.0

    Pentium 2 400 MHz

    Card OR PCI-GPIB

    Instron 8511 controller

    In order to obtain performance I want what components do you think I will need to replace and that tests can do to learn more?

    Any help is greatly appreciated.

    -Daniel

    The user?  SCNR

    Speed your Instron GPIB just tells you that it would be able to send data fast enough. I do not know this instrument, but I would like to dig into the manual to see if it is possible together in a way he could make use of this speed. Perhaps by internal scripts, triggered material acquisition, low resolution... ask 1000 values once instead of a 1000 times.

  • Coordinates of the elements in the array

    Hello
    I'm playing with mouse click coordinates, especially because his Friday afternoon , but also because it might be useful

    In the attached code, I want to click on one of the channels of my table control and what element of the array corresponds to (which later will be used to draw the other pieces of the code based on the content of table)

    I can use the position of the table and the coordinates of the mouse and everything works fine.
    BUT... only if I select the zero element until I run the code. If I select another element, then run the code, I get wrong results.

    -Are there a way to get the coordinates of the element zero of my table regardless of what the user has done?

    I can think of workarounds using the coordinates of the control table (rather than details of the chain), but it is affected by the label size/visibility control feels so less reliable.

    Using version 8.5.

    Thank you

  • Asp for the URL prefix Mac

    Hey guys,.
    Just buy a mac and love it!

    My problem is that I create asp pages and would like to develop on my new mac, but we all know the mac usually run a test like iis server. So when you try to set the url prefix I can't seem to find what would be the URL. I know that on my pc, the prefix is something like http://localhost/SOMETHING/ but I would like to know the prefix so that he can work the Mac. I read somewhere that when your development asp pages on a mac that you would have to use a pc in network runing iis inorder to test pages. In short, when you try to set the prefix of test server I can't seem to connect.

    Anyone know the prfix or can you show me an example of how you have configured your on your mac? I use Dreamweaver MX and OS X.

    Thanks in advance.

  • The default value for the elements of the page get ready when the session is disabled

    Hello

    I am facing this problem, do not know how to solve this problem. Basically, the default value 'elements' on the page don't prepare you when the session is disabled and I visit the page for the first time. So when I check the session for the first time, all page elements are null. But when I revisit the page, page elements sometimes gets.

    Don't know what I'm missing here... Someone has encountered this problem before?

    Thanks in advance! Kindly let me know if you need more clarification.

    Is there a way that the page element can be defined at the time the page is loaded for the first time?

    Yes. Create a "Page Rendering" PL/SQL process. That it is very early in the page rendering (i.e. "on charge ‑‑ after Header"). Set the value of the element of page here:

    BEGIN
      :P10_MY_ITEM := 15;
    END;

  • Complete the URL for popupURL of a table/Page element?

    Hi all
    Someone please tell me if the URL to run a report BEEP can be filled with a table/page element when using popupURL and if so, how?

    Background:
    I have a Table called TBL_LETTERS with a column varchar2 REPORT_URL
    I have a Page (Pg 303) that fills a Page of text element (P303_REPORT_URL) with a URL string appropriate to the table.

    Here's my problem:
    I would like to replace my function javascript to work (see below):

    Run myLetter_40()
    {
    popupURL ("& BI_URL. Guest/DEV/TEST/FRM_40/MM_40/MM_40.xdo?_xpf= & _xpt = 1 & P_CASE_ID = & P303_CASE_ID. & P_PERSON_ID = & P303_PERSON_ID. & _xt = MM_40_xf = rich text ');
    }

    with something like:

    Run myLetter_40()
    {
    popupURL ($x("P303_REPORT_URL").value);
    }

    .. .but it does not work.

    With my knowledge of limited javascript, I can only imagine that the variables with success a value in my first example of assigned function do not succeed to my second, I'm probably just passing through all this as a simple string (like this: + & BI_URL.) Guest/DEV/TEST/FRM_40/MM_40/MM_40.xdo?_xpf= & _xpt = 1 & P_CASE_ID = & P303_CASE_ID. & P_PERSON_ID = & _xt = MM_40_xf & P303_PERSON_ID = rtf +), but would appreciate very much all the advice.

    What I need to
    a. create the string of REPORT_URL differently in the table so that when it is passed to the Page element it includes the required variable data?
    b. something completely different?
    c. the forget, it is not possible!

    PS. I use Apex 3.2.1
    Thank you in advance.
    Sue

    Published by: smp245 on August 21, 2012 14:19

    Hi Sue,

    you could build the url with javascript like this:

       popupURL('&BI_URL.Guest/DEV/TEST/FRM_40/MM_40/MM_40.xdo?_xpf=&_xpt=1&P_CASE_ID=' + $v('P303_CASE_ID') + '&P_PERSON_ID=' + $v('P303_PERSON_ID') + '&_xt=MM_40_xf=rtf');
    

    the javascript $v function belongs to the Apex javascript library and gets the value of an element of HTML page.

    Kind regards
