Hidden items in apex 4 now hidden and proteced

Hi all,
The option hidden and proteced is no longer available in Apex 4. Now a hidden item is automatically hidden and proteced.
This gives me problems with my app.
I created a page with a menu.
When I click on the menu my page gets filled with content.
I do this with a text item.
In this text item I fill the content id. When I click on the menu a javascipt fills the text item with the correct content id.
The content region reads the content id and the content gets displayed.
Now if I set the text field as hidden, the page gives me an error
Error      Checksum error for Hidden and Protected item ID (2036114079384286), value (5), posted checksum (8EDF8C5C97169E49A9A12B5B15897DB5), expected checksum (********************************), index_i (1), index_j (1), index_m (1);
Any suggestions?

Huh?
There's a type of "Hidden" and a separate place under "settings" for "Protected" and you answer Yes or No from the select-list.
Does this not work for you?

  • Displaying not hidden items in the page

    Hi,
    Could you please let me know how I can identify hidden items programmatically? i.e. We have some items in a page and suppose some of the items are hidden. I need to provide a list of not hidden items. How can I recognize hidden items and not to display them in my list?
    Regards,
    Setareh

    Thanks for your reply. But I need to identify hidden items not inactive or deleted items. So far I know active field in wwsbr_all_items doesn't get value for hidden items just for deleted, inactive, and active items.

    Tim,
    I have discovered a very strange behavior of my Page

    But this empty row is only be displayed in Internet
    Explorer! In Firefox everything looks fine!Although hidden items are 'hidden' they're still part of the HTML and consume space within the HTML source of the page. Is ApEx just putting these items inside a td tag that shows up in the browser? Maybe you could post an example on apex.oracle.com.

  • Update Hidden Item In Manual Tabular Form

    Apex 3.2
    I have a column in my tabular form which is used in an update.
    APEX_ITEM.DISPLAY_AND_SAVE(34,f.qtyuser) oldqtyuser
    I do not want the users to see this column, so on my edit report I unchecked the Show checkbox.
    Now I get an error message and my update fails.
    I have tried changing it to
    APEX_ITEM.TEXT(34,f.qtyuser,10,6) oldqtyuser and unchecking the Show checkbox but still it fails.
    I have tried changing it to
    APEX_ITEM..HIDDEN(34,f.qtyuser) oldqtyuser and unchecking the Show checkbox but still it fails.
    How do I achieve this
    Gus
    Edited by: Gus C on Nov 14, 2012 11:56 PM

    Hi Gus,
    Struggling to remember what is available in 3.2. What I did in this version was to append the hidden item to another item in the table. So for example if you have a text box in the table then use:
    APEX_ITEM.TEXT(33,f.othercol,10,6)||APEX_ITEM.HIDDEN(34,f.qtyuser)
    That way there is not extra column, but the hidden item is still displayed in the table.

    Hi,
    If you are on Apex 3.x or higher , try

    alert( triggerItem.slice(6));
    $s("P4_SELECT", triggerItem.slice(6));   
    /* Alert hidden item value you did set */

    It seems to be an excessive use of the items. It's just the variable. Right ?
    Thank you

    Andrew,
    "doesn't seem to work" is the worst way to describe something not working ;)
    1. the name of your on demand process is case sensitive
    2. have you tested the on demand code in SQL Workshop > SQL Commands? does it return the expected XML?
    3. put an
    alert(gReturn);
    in your javascript code after
    gReturn = get.get('XML');
    and see what kind of alert you get.

  • How to check hidden items

    Hi,
    On a existing portal installation (10g Release 1) I've a lot of hidden items. I need to export these items to a new release of portal (10g Release 2).
    The information of hidden object is not define inside table wwv_things. I check on several tables/views of the portal schema but I cannot find the table/view where this information is stored.
    Is there a way to create portal items in 10g Release 2 with pl/sql packages and to hide these items ? I found a recommandation to set the publish date in the future but in our case, this do not correspond to the expected behaviour.
    Thanks in advance for your help,

    But you're right that there's no API method for hiding items in 10.1.2.
    In 10.1.4 the hide_in_browse parameter of wwsbr_api.modify_item can be used to hide the item:

  • Get item value of hidden item in java script on standard report

    I've a report with following query:

    "GTEMPID",
    "NORMTEXT",
    "ITEMTYP",
    "ITEM",

    from "#OWNER#"."ALAVIS_GTEMPDETAILS"
    Item GTEMPDETAILID is hidden (set in column attributes).
    I defined an onclick event in the report template to set the value of GTEMPDETAILID into a Page item. This works, if the GTEMPDETAILID is not hidden. But how can I get the value of an hidden item in javascript?

    I am guessing this hidden value is not a protected item because youre manipulating the value. How about setting is a textfield but inside the "HTML form element" property, specify style="display:none;" or you can nest <script type="text/javascript">$x_Hide("ID_OF_TEXTFIELD");</script> in the page somewhere...
    Question, have you tried using $x_Value('ID_OF_ITEM','VALUE_OF_ITEM') ? this is APEX javascript API
    you can also use $x('ID_OF_ITEM') to retrieve DOM object, or $v('ID_OF_ITEM); to retrieve item values.
    Let me know if you need additional assistance.

  • Javascript: set value of hidden item

    Hi,
    I have a select list and a hidden item on my page, after select a value, I want to write this value (and a little bit more) to the hidden item.
    So I have done the following...
    applied to page html header:
    <script language="JavaScript" type="text/javascript">
    function setExpress(item_id)
    html_GetElement('P230_HIDDEN').value = 'Test ' + html_GetElement(item_id).value;
    </script>
    and in selection list I set the HTML Form Element Attributes to onChange="setExpress(this.id); .
    But nothing is written to the hidden item. When I make it a text field it works correct.
    Isn't it possible to set a value of hidden item by javascript? Is there another way to do this (without computation)?
    Thanks for help
    chrissy

    Hello chrissy,
    I don't see the connection between the item being Hidden or Text. The item id stays the same, and so the JavaScript reference to it.
    It is possible to assign values to hidden items using JavaScript, just as you did. In the following page - http://htmldb.oracle.com/pls/otn/f?p=22814:8
    -you can see a working example of your situation – select list populate a hidden item, then display by using alert.
    After selecting from the list you should TAB out, so it will fire the JavaScript event. In your example, you were using onChange. I think that could be problematic in cases were the default value (first value) of the select list is the one chosen – no change there. In my example, I'm using onBlur.
    You can see the JavaScript on the source page.
    Hope this help,
    Arie.

  • Interactive Report filtering with hidden item column names

    I have created an Interactive Report and changed some of the default column headings by using hidden Items with appropriate title. However, when I look at the filter option in the "Gear" drop-down, the only column names which appear are the default ones. There are blank lines for the columns using hidden Items. Any suggestions for having the hidden item content appear in the filter column name list?
    Thanks,
    George

    George,
    What is it you're actually trying to do here? Maybe there's an easier way?
    Hidden items aren't going to show up in the Column List.
    I'm guessing you're trying to separate a long list of column names using '----------' or something like that? We're looking to do just that in our application, but obviously we don't want to users selecting these dummy entries. We tried using the IR column groups, but those make the list look even more cluttered IMHO. (Plus setting the sort order w/in the groups doesn't seem to affect the drop-down column lists, which seems counter-intuitive to me).
    If anyone has other suggestions for breaking up the column list display, I could use something immediately (going into beta-test in 2 weeks!).
    Thanks,
    Stew

    Hello,
    Check to make sure you don't have those items set to escape html.
    Past that are you sure your javascript is putting in the &lt;br /&gt; tags correctly? before you submit fire a alert that shows the value of the hidden item and make sure it's correct there.

  • How to set date value in hidden item

    I have a form which has an date item, P1_MTIME , if I use data picker and an procedure (After header)to define its default , as
    begin
    :P1_MTIME := to_char(sysdate,'DD-MON-RR HH24:MI');
    end;
    Everything works fine, but when I change P1_MTIME to hidden, I can only get its value set to date, not hour and minutes, such as 2006-06-23 00:00, what I did wrong?

    Why not just have a hidden item with the ID so that when you create (insert) it is null and you insert sysdate and when you are editing an existing value and hence have the ID you update. This logic is easy to place in a page process (when the page is submitted)
