Displaying an application item's value from a page template

Hello,
I have an application item 'F50_TEST' and I need to display its value on every page that's using a specific page template. I think I can access data like the APP_USER by using #APP_USER# in the template, but can I access application items that way?
Thank you,
Pavel

Hello,
In your template, you can use '&F50_TEST.' (notice the trailing dot) to display the value .

Arie.

Generic proceeding for setting application item's value from javascript?

For the moment, all I can think of is a javascript function calling an on-demand process that looks like this:
function setVariableValue(pName, pValue){
var gReturn;
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=odpSetVariableValue',0);
get.addParam('x01',pName);
get.addParam('x02',pValue);
gReturn = get.get();
get = null;
odpSetVariableValue
begin
execute immediate ':' || wwv_flow.g_x01 || ' := ' || wwv_flow.g_x02;
end;
Is there an APEX function to do it without "execute immediate"?
Igor

Hello Igor,
I think you can do the same thing without actually executing a PL/SQL Process (look here for an example).
function setVariableValue(pName, pValue){
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=dummy',0);
get.add(pName, pValue);
var gReturn = get.get();
get = null;
(The Application Process dummy doesn't really exists...).

Pass value from one page to another

Hi All,
"How to pass the value from one Flex page to anothere Flex
page".
In First Flex page contains One Inputtext and one button is
there.After entering the data in inputtext box,the user clicks on
the button then get the data from inputtext box and then i need to
send that value to another flex page and display there.
Can u tel me plz............
Thanks & Regards,
Nagarjuna.

I believe you are thinking in terms of HTML and traditional
page coding. As an old school ColdFusion guy I understand it is
difficult to leave that behind. (at least it was for me.) Unless
you literally have two different HTML pages that each have their
own Flex app running in them you do not need to send data from one
page to the next like you would with Web Forms. (If you are doing
that you may want to simply write the data to a Shared Object, Pass
it to a server to store and then feed back into the second Flex App
when it loads or perhaps use the ExternalInterface to then pass it
through as a series of URL parameters that can be loaded into the
next Flex App.)
In Flex you do not have to worry about loosing state between
pages because there are literally no pages. Only different views.
You would not "Send" the value from one page to another. You
provide a mechanism for the second view to reference the same model
or data object (most call them ValueObjects) that the first view is
setting via the form fields.
You would want to use a ValueObject in the first VIEW and
then fill the object with the form data using setter methods on the
object. For example set the fields onChange event to call the
setter on the object and pass it the form fields value as the
property. Alternately you could bind the values of the model
directly to the fields so that they automatically obtain the data
that is being filled in.
Depending on how complex of an application you are going to
build and how scalable it must eventually be you have many
different options to choose from to allow the second View to use
the data set but the first. However to make the application
ultimately more scalable you are going to want to keep your view
separated from the controller and that separated from the
Model/ValueObject. (By seperated I mean in different classes.)
I would suggest looking up the subject of MVC in Flex and
also the Mediator Design pattern. There are many great sources of
information.
Here are a few links that may help with ideas.

Automatic Row Processing - Preset a value with value from other page

Hi everybody,
I have created a form on a table with report. I added a dropdown field to a sidebar region on the first page the groups and selects only a couple of these entries. (Think: only people for the department selected in the drop down field). Now when I click on the normal create button the id field for the department should be filled automatically with the value from the page before, where something was already selected in the drop down field. The id field is a hidden field on the actual create page. Maybe it is not working because the field is linked to the database column to make the automatic row processing work or something. I tried computions on both pages and setting the values. Nothing seems to do the trick.
Any help would be greatly appreciated.
Thanks,
Henrik

Hi,
these are the values I currently see:
108 14 P14_SELECTEDSS Display as Text (escape special characters, does not save state) No
108 14 P14_CHARACTERISTIC_ID Hidden and Protected Reset to Null No
108 14 P14_SHAREDSERVICE_ID Text Field 30 Inserted No
108 14 P14_CAPTION Text Field No
108 14 P14_CATEGORY_ID Select List No
108 14 P14_WEIGHING Text Field No
108 14 P14_DESCRIPTION Textarea No
I also have to say that I deleted the computations I created earlier again cause they did not work and I had the same values for these variables. I am trying to (pre)set P14_SHAREDSEVICE_ID to P13_SELSS when I click the create button on page 13.
Thanks again,
Henrik

How to get attribute value from standard page ?

Hi,
How to get attribute value from standard page ?
String str = (String)vo.getCurrentRow().getAttrbute("RunId");
But this value is returning a null value ....
Can anyone help me to get this attribute value which is actually having a actual value .

getCurrentRow() would always return null if no setCurrentRow() is used.
Please check the page design and understand how many rows of VO are there. You can also use the following to get the row:
vo.reset();
vo.next();

i 'm doing what exactly you mention here .
my problem here is
i have 15 columns
i am executing a query based on the values of the column(column name) in the target page
1)here i am passing(all) the column values to the next page-but i want to pass only one column values(column name)
when i click on any cell of that column
OR
2)i can pass all column name to target page -there(in the target page) i can filter out
i think option 1 would good if you filter out the unwanted columns

Windows Phone 8.1 xaml, c# ComboBox does not display selection when first item is selected from full page list.

I have 3 comboboxes on a xaml page and most of the time when I select the first item on the full page list displayed when the number of items are > 5, the screen returns to the combobox and the box is blank. The combobox.SelectedItem is valued but it
does not display. This does not happen every time and I have seen this using the emulator and my windows 8.1 phone. If I select any other item in the list they always display but when I go back and select the first item the box is blank.
Does anyone know what I could be doing that is causing this?

Thanks for your help. When I run the code below and the page is displayed, I select an item from the page list and it displays fine and then I select the first item from the page list and I do not see that selected item in the box.
If I remove the SelectedIndex=0 it all works fine except I do not have an item selected for the initial display. Below should show problem and should work copy/paste in universal blank app.

Application Items - Request Value?

Hi,
I am just wondering if someone can explain to me about the request values.
I set up a page item to display the request value. Now when I put the request attribute into the url, this item displays the value of the request. Except, when calling javascript:doSubmit('SOME_VALUE'); this value doesn't appear in the page item. I was under the impression this function sets the value of the request.
How does apex know it is the request when it isn't in the page item? (i.e. when using it as a condition).
Ta,
Trent

Hi,
Why they act differently, I couldn't say. I have seen this in the past, though, and you could "save" the request value in an Application Item and use that in the condition. Have a look at: Re: Trying to identify my tabs in my tree navigator sql

Enable/Disable item Based Value from Select in Tabular Form

Hi Guys
I want to Disable text field in Tabular form, Based on the Select List Item Value.
Let's Say
I'm having one select lista and text box in each record in tabular form.
Select List having 2 items ... Add Text(return value 1) and No Text(return value 2)
if value =1 then i want to enable text box , so user can enter value.
if value=2 then text box won't allow to add text or will become disalbe.
Please Help

Hi,
You can do this by using a small java script
<script language="JavaScript" type="text/javascript">

</script>Here P2_Text is the text box whose value I am enabling or disabling based on the selected value from a List box. On The list box I have onChange="javascript:FldEnableDisable(this.value)" ( You can specify this under HTML Form Element Attributes)

Viewer slow while retrieving data while changing value from a page item

Hi, I am using 9.0.2 to create reports. My end-users are using Viewer to run these reports. Recently, we are experiencing performance problems with Viewer. We have reports with Page Item. Let say a report takes 1 min to run. After running the report if a different value is selected for a page item, it is takes another 1 min to get new data. Whereas, Desktop is not taking any additional time (noticable) for a different value for the page item. Recently, we are experiencing this problem. I thought that it was cache problem in Application server, so we restarted all the pieces in aps server. However, the problem still exists. We are using a materialized for this particular report.
Any tips would be highly appreciated. Thanks.

The performance differences can be attributed to the differences in product. Desktop is a client server product. A query executes and ALL data is returned to the desktop. You can manipulate that data in any way and the database is not required. Web (Plus/Viewer) only return the data needed to satisfy the query currently being viewed. If you change a page item, a database call is made to retreive additional/different data.
In other words this is just how things work. You can alter settings in your prefs.txt file to improve performance in Viewer/Plus. Changing number of rows returned, memory settings, row fetch limits, rows per fetch all can improve/reduce performance.
As best I know there is not a "magic" setting for these values. It is based on the server/volume of data/workbook content/ workbook layout. etc. Crosstab workbooks are much slower to return data than page -detail.

How to read application item's value using javascript

Is there any way to read value of application item using javascript?
Thanks

Javascript can access the objects rendered for the page you are calling. This is why the $v function will do the work if calling it for a page item. However an application item isn't rendered on the page - the session state of it is only stored in the table. This is why you need to do it the way I described. You could do a workarround and create a hidden item on your page and compute the value of it using the application item value. Then you would be able to get the value of your application item using $v function.

How to display JHeadstart flex item default values

Dear All,
I have defined a number of FlexRegions and FlexItems and I'd like to display the default values (specified by a SQL query in the Flex Item Def Editor) next to the input text field using the JSF EL expression #{row.defaultValue}.
This works fine as long as the user has not provided a new value for the flex item. Once (s)he has done this, the default value gets cleared. I've been able to programmatically obtain the default value by invoking the method executeDynamicQuery("somename", row.getDefaultValueQuery()) on the FlexItemDefsOuterJoinedWithFlexItemsRowImpl instance, but
I'd like to be able to always display the original default value in the .jspx page.
Any suggestions would be greatly appreciated.
I'm using JDeveloper 10.1.3.3. and JHeadstart 10.1.3.2.52.
Regards,
Ibrahim

Hi Steven,
Thanks for your reply. You're absolutely right of course. We wanted to provide functionality to submit 'request for change' requests, whereby we would display the current value of a given attribute (e.g. salary) next to the new value provided by the user.
We wanted to 'misuse' the default value query aspect of flex items for this purpose. The flex item default value query would be used to retrieve the current value each time the request for change record is displayed.
We managed to achieve this via a trick, so please consider this post as solved.
Once again many thanks for a marvelous product.
Regards,
Ibrahim

Displaying ui element when selecting value from dropdown

hi,
i have a requirement when user select value from dropdown( some x from dropdown) textedit ui(where user can enter some text) should be displayed and submitted. please give some idea

Hi Babanmohi ,
First create a node in your context and under that create an attribute. Then add a Dropdown by Index and TextEdit UI on to your view. Bind both the UI element with the same attribute.
Then create an action on onSelect event of the DropDown UI element. Go to its implementation and write the following:
wdContext.current<Node name>Element.set<attribute name>(wdContext.current<Node name>Element.get<attribute name>)
For example, if in my context there is a node called testnode and under that if im having an attriburte called name, then do the following coding in the onSelect method of dropdown:
wdContext.currentTestnodeElement().setName(wdContext.currentTestnodeElement().getName());
Reply me if you have any issues

How to populate a filter field in one page with the value from other page

Take the classic report with form application.
on page 1 (report) I have a filter (dbname) for the records that will appear in the report. Say that, I enter "ap02" in the filter and all records where dbname starts with "ap02" will display. It works ok.
Then I click on "create" button and page 2 appears. I enter all fields except the dbname. This field is generated, at "pre-insert trigger on the table".
What I want is when I press the button "create" on page 2 to pass the value of the generated dbname field into the filter in page 1 so when that page refreshes I will have only one record on the report page (1). I understand that the dbname at the page 2 level still empty because it is generated by the trigger. How do I have access to that info to populate the filter.
Thanks for your assistance

Joe - Work backwards from the value generated during the execution of the trigger. You have the value there so you could save it into a package variable right then (create a package with a variable and assign the value to the variable). Then create a process on the page (after the DML process) to assign the value of your package variable to a page item. Then in the branch back to page 1, pass the item. (Or without messing with the branch, the process could simply assign the package variable directly the the page 1 item -- :P1_ITEM := my_package.my_var; ).
An alternative would be to use the "returning into" feature of DML to capture the PK of the created record into an item. Then the next page process could use the PK to fetch the new row and get the dbname value for passing to page 1.
Another option would be to update session state directly in the trigger.

How to pass the value from one page to another page

Dear Gaurav
I have three pages
1-creation page
2-search page
3-creation page
in first creation page I have column name user write a% and submit to that search for that name.
it is going to second page (search page)name a% is passed and search that corresponding value,the corresponding values are not there user will call third creation page and enter the details and save and click back to first page the value is not calling passing from third page to first page I submit the button in 3rd page the error is coming like this.
The requested page contains stale data. This error could have been caused through the use of the browser's navigation buttons (the browser Back button, for example). If the browser's navigation buttons were not used, this error could have been caused by coding mistakes in application code. Please check Supporting the Browser Back Button developer guide - View Object Primary Key Comparison section to review the primary causes of this error and correct the coding mistakes.
Cause:
The view object xxcrmleadmgmtAM.xxcrmleadmgmtVO contained no record. The displayed records may have been deleted, or the current record for the view object may not have been properly initialized.
in first page column name I removed view instance and view attribute the value is passing from third page to first page
my requirement is the value call from 3 to 1 and user will enter remaining fields in 1st page and save the records.
