BUG? Presentation of elements via Dynamic Action in Internet Explorer generates "null."

I first noticed this using the newly improved apex.oracle.com. When I have dynamic action that must send the values of page element and the value is null / empty, the call to post/ajax result includes the literal 'null' as the value for this parameter.

for example
p_flow_id = 65928 & p_flow_step_id = 2110 p_instance = 574862348021401 & p_request = FLOW_PPR_OUTPUT_R1858426911545391_reset_R_1858426911545391 & p_arg_names = P2110_VENDOR1 & p_arg_names = P2110_VENDOR2 & p_arg_values = 3754 & p_arg_values = null

This only happens in Internet Explorer. I use IE9, but it seems to work that way, if I put it in IE8 mode as well.

I returned and tested in the Apex 4.1.1.00.23 and I got the same result.

Hi Greg,.

Thanks again for the follow-up. You are right, it is the "Set Value" operation that causes the problem when it is called with a null value. In fact, it's a bug of IE underlaying.

See http://stackoverflow.com/questions/5387038/null-values-shown-in-form-fields-in-ie and also http://bugs.jquery.com/ticket/5163 strengthening jQuery

I will file a bug to use jQuery.val () workarounds to the problem.

Thank you
Patrick

  • Masking multiple elements with dynamic action me gives error

    Hello

    I have a selection list, and I tried to create a dynamic action on this subject. When the list is zero I want to hide items. The problem is that I thing 200 articles on my page and when I try to list them all under the dynamic action, it gives me an error or cut off my list. I tried created two separate actions of dynamics, but it did not work. Any suggestions? Any help would be so appreciated. Thank you!
    The problem is that I thing 200 articles on my page and when I try to list them all under the dynamic action, it gives me an error or cut off my list.

    Is it that you were able to cross the mark of products/page 100? But the official documentation has to say otherwise:
    http://docs.Oracle.com/CD/E23903_01/doc/doc.41/e21674/limits002.htm#BGGIECDF

    It is possible to define and to return more than 100 items on a page, but you will get a 404 error when running if you submit a page with over 100 articles (including the hidden objects and elements of page zero). You will not be able to present and process a page that has made more than 200 points. You will be able to set more than 200 items in your page and send, and then process the page If the actual number of elements returned is limited to 100 or less by using permissions and conditions.

    * Specify error messages you received

    ORA-20001: error creating dynamic action sub-action name = "NATIVE_HIDE" id = "" ORA-01461: can bind to a LONG value only for insert into a LONG column > "

    You seem to have exceeded a 4000 or 32 K bytes on a column of metadata for dynamic action when you set the dynamic action. Because you cannot use all 200 points at the same time, you must create multiple dynamic actions that correspond to some subsets of items are actually rendered.

  • Back to zero/recalculate value if the element with dynamic action

    Hi all

    What I have is a part of "total amount". When the other elements on the form are filled, these values are subtracted from the total. My problem is that when a few points to say a filled out, but then set to zero, the figure in the total does not reset. If no new figure added, are more excluded.

    For example:
    total = 10
    Value of 1 changed to 5. Total = 5.
    Value of item 2 changed to 1. Total = 4.
    Value of 1 changed to 2. Total = 2.

    I find it tricky is because the total is derived from an action of current setpoint led other points. Finally, I would like to reset or re - run the calculation for the total, without duplicating the original action of the set value. I tried to use a dynamic action "Refresh" but I don't think that work in this way. Is there another way?

    Why not save the original value to an item hidden page (or even in a global variable set before you run the JS calculation for the first time in javascript).
    During the reset, set the value of the element with the value of the hidden (or variable).

    Any ideas why Apex does not pass the value of the element to the function call?

    You must set 'Page to present' to be 'P2_SCHEME_CAT_CODE '.

    This takes the value from the browser and affects it in session state, which makes available to your PL/SQL

  • How to refresh an image element displayed dynamically

    Hi all

    This is Pavan,

    I use apex 4.2.3

    try to update an image dynamically, but did not,

    example I use the id selection list depends on the id of the image should be displayed, I used image is displayed to display the image (sql statement returned blob column),

    I created dynamic action on the item to change refresh, but his does not work

    later I thought that change doesn't think so I created dynamic action run plsql code (start null; end ;) the items to send (the select list item) page.)

    still no luck, am I miss anything please let me know.

    Thanks in advance,

    Display pixels do not support DA update:

    Refreshment - triggers a refresh of the elements concerned. Note that not all elements support a refresh, you can use it for interactive reports, conventional, graphical reports, list view and all types of elements with the LOV support cascading. Plug-ins can support this action as well.

    Display the image using a classic that will allow a DA standard to use r.

  • value of the element is not common when used in dynamic action

    I'm learning the 5 apex and I wanted to create a page that would update the fields in a record by entering the unique id of the recording using a dynamic action with plsql.

    When I click on the button update the value of the element of the text uses the previous value and not the input current. The 'works' update, but the ID values are not appropriate.

    How can I make sure that when I click on the update button, the dynamic action will get the current value of the text element and not the previous (when the page was submitted)?

    I created a quick demo or what I was testing in apex.oracle.com and always gives me the same result.

    What dynamic action event and what types of action are involved here? Provide details, or better yet share identification information of developer comments for the apex.oracle.com workspace so that we can see the demo.

    If the dynamic action executes an SQL statement or a PL/SQL process on the server that requires page updated element values in session state, specify these items as part of dynamic action Page to submit items .

  • dynamic action sets the value of the element, but not save to DB on submit

    I'm working on a page where the value of several to show only the page elements are defined using a dynamic Action.  They are set when the user selects a value in a list of selection (and is based on the value of the selection list).  Dynamic action is triggered on a list selection change event and then runs the real action "set the value.  The selection list displays the names of sales representative.  The three fields dynamically filled are the org structure (that is, their chain management).

    For the action to set the value, I use a defined Type of SQL statement:

    Select VP, DIR, MGR

    of SALES_ORG where SSR =: P20_SSR

    In the affected elements, I have fixed Type of selection to the 'item (s)"and the value of the Item (s) for 'P20_GVP, P20_DIR, P20_MGR.

    Dynamic action works fine for the display of the page (that is, when I select a sales representative in the selection list dynamic action properly updated only display value fields three).  This page is a form in which the user submits information relating to the rep.  When the page is sent, all fields are filled in a new record of DB with the exception of three that were populated dynamically above.  These fields get the values NULL.

    When the dynamic action updates the values in the three fields is - it does not set the value of session?  Why these fields don't are not taken into account in the submit other ideas > process Page?

    I use 5 APEX with Chrome on Mac (Yosemite).

    Thanks for the note.  I didn't only display the items could not be used in this way.  I think I'll take a different approach with the design; given that the org structure is in another table that I can simply refer to that by rep when necessary rather than saving the information uploaded to the page of the form.  The reason why I have not fill the screen only the points of loading the page is because I don't know what the values should be until the user selects a sales representative in the selection list.

    I'll change the design to one of the following:

    1) change the display only items of standard text field.  NOTE: if I make the text read-only field that causes other problems when loading (I get the message "violation of protection Session state").

    OR

    2) do not include org structure in the download folder and just refer to table org Rep when necessary.

    Thank you!

  • Alertify Plugin - how to call via Javascript and not by a dynamic Action

    Hello

    Environment: Oracle APEX v4.2.1 | Oracle 11g R2 | IE8 Web browser

    Hoping someone can help, I use the plugin Alertify via a dynamic Action, but my question is, instead of use this via a dynamic Action, I actually want to make the same call I do via a dynamic Action but rather using javascript.

    So, by using a shape any JavaScript API in the Alertify plugin, I want to call an alert notification standard with the message and the delay effect until it disappears once more.

    Is it possible to call this plugin in this nature using javascript?

    Thank you.

    Tony.

    You can always use the plugin and a custom event.

    Create a dynamic action:

    • Event: Custom
    • Custom event: ALERTIFY_DELAY
    • Selection type: jQuery Selector
    • Selector: body
    • 1 real action:

    Add the following code to the section "run when Page Loads:

    window.setTimeout(function(){
      $('body').trigger('ALERTIFY_DELAY');
    }, 3000);
    

    This will cause the "ALERTIFY_DELAY" event fires after three seconds.

  • Can not set a value by the executed dynamic action on the page element "selection list."

    I created an agenda of the page 'list of selection' and I want to when I change a value in another element of the page set only 'screen '.

    These are the dynamic action attribute:

    Note: when I change the previous attribute of 'Redirect and set', dynamic action run and properly value, but the value was hidden soon

    I want to value when the value of change of select list according to this change successfully.

    Please, advice me,

    Hello

    you set the value of the 'Page elements to submit' to P29_PURCHASE_ORDER?

    Then, the SQL statement would use the current selected value.
