Setting Page Item from Hyperlink

Hi,
I am currently developing an APEX application that will show a Google map of our kiosk locations. It builds the javascript in a PL/SQL package using htp.print. For each marker it displays for the kiosk, I'm customizing the info window displayed when the marker is clicked to show the kiosk name, the address and some hyperlinks. One of these hyperlinks will go to another APEX page that displays orders for that kiosk. So, what I'm trying to accomplish is to set a page item value on the page when the hyperlink is clicked that will be used in a page query to pull the orders. I am not much of a javascript programmer, so I'm having some issues. Here is what i'm currently attempting:
Withiin the FOR loop that builds my markers, I have defined a 'function' as follows:
htp.print('function setKioskCode (P4_KIOSK_CODE) {');
htp.print('var kioskcode = '||''''||<location from cursor loop>||''''||';');
htp.print('$x('||''''||'P4_KIOSK_CODE'||''''||').value = kioskcode;');
htp.print('}');Then, this is how I'm building the hyperlink in the info window (i've removed the link tags and single quotes so I could post the code). Using this method, I get an error on the load of the map page that says ' Expected ")" '. I can't find any syntax errors in what i have done from what I can tell (I could definitely be wrong!).
l_order_link := href="f?p='||v('APP_ID')||':6:'||v('SESSION')||'" onclick="javascript:setKioskCode('||''''||'P4_KIOSK_CODE'||''''||');">OrdersWhen I remove the parameter value from the javascript call like this. It loads the map successfully, but, of course, the hyperlink on the marker info window doesn't work.
l_order_link := href="f?p='||v('APP_ID')||':6:'||v('SESSION')||'" onclick="javascript:setKioskCode();">OrdersAny help would be much appreciated. And please let me know if you need any further info.
Thanks,
Troy

Thanks for the reply, Jari.
I have determined you definitely have to use the v('APP_ID') and v('SESSION') in the href statement. Otherwise, it puts the &APP_ID. and &APP_SESSION. in the URL.
I tried the 'onclick' syntax you provided and it still does not work. I get the error I reported above. It's looking for the closing parenthesis and doesn't like a parameter being provided. If i remove the parameter from the function, the page loads and the hyperlink goes to the proper page but it doesn't populate the page item. I don't know why it doesn't like a parameter for the function.
Thanks, Troy.

Set page item from a stored procedure

Dear reader
We would like to have a stored procedure to run every 10 minutes. When the procedure starts, the user has to be warned that the update process is running.
When the procedure is finished, the user should receive a message that the update process is finished.
What I had in mind was to set a Page 0 item 'P0_REFRESH' and set his value depending on the status of the update. Then add a dynamic action with a change event. So everytime the value of this page item changes, the user will receive a correct message.
Does anyone know if it is possible to set a page item from a stored procedure?
Kind regards

I found a solution by querying the user_jobs table. In Apex, I created two page 0 items that hold the current status of the job (online, offline) and the old value of the job.
Online of offline in the current status item is determined by a decode on "this_sec".
The enext step was to include a html region in P0 that contains some javascript. This javascript will display a message when the values of the new status is different from the old status ;)
Many thanks for bringing up the ideas.

Setting page items from Stored Procedure/Package

Hi,
Can anyone tell me if it is possible to set the values of page items from stored pl/sql code. I have some reasonably complex biz logic that I want to package and store in the database (not just call an anonymous pl/sql block through a page process). However within that stored code I want to set items on my page based on input parameters, other items on the page or calculations eg.
I want to do something like:
:P6_INT_ACC_START_DT := p_bony_auction_dt + 1;
when trying to compile this code I get invalid bind variable error
I also tried:
V('P6_INT_ACC_START_DT') := p_bony_auction_dt + 1;
but got invalid use of V function error
Any ideas?
Thanks, Robert

Call apex_util.set_session_state:
apex_util.set_session_state(p_name => 'P6_INT_ACC_START_DT', p_value => p_bony_auction_dt + 1);
...although be aware of date-to-varchar2 conversion and use date format masks explicitly.

Setting Page Items from SQL Query

Hi, 
I am using "SQL Query (PL/SQL function body returning SQL query)" for a report. In the body of the sql query, after calling a function, I have the following statement: 
APEX_UTIL.SET_SESSION_STATE( p_name => 'P13_MESSAGE', p_value => 'Contact Tech Support' ); 
and I find that I cannot save the query. I get an error message: 
Unexpected error, unable to find item name at application or page level.
ERR-1002 Unable to find item ID for item "P13_MESSAGE" in application "4000". 

I do have the field 'P13_MESSAGE' on my page. 
Can't this API call be used within such a query type? Is there an alternative to this? 
Thanks in advance 
Vasan

Scott,
I have given the source of the region, below. Its type is 'SQL Query (PL/SQL Function body Returning SQL Query'). 
"Get_State_Hit" is a procedure in a package. I have not shown the name of the package here.
Please give me your suggestion. Thanks Vasan 
========= 
DECLARE 
l_sql varchar2(100);

ELSE
Get_State_Hit ( another set of values from user-interface );
apex_util.set_session_state( p_name => 'P13_MESSAGE', p_value => ' MsgString 2' );
END IF;

Access page item from Javascript

I have searched the forum, and based on my findings this is what I've done so far:
I have a page item where the Google Map key is stored. I want to access it from Javascript so that I can call the Google map with the key. (Note: The key can't be hardcoded as it will be pulled from DB according to the environment/url the app is running on. e.g. - dev, test, production.)
Here's a javascript code block:
<script>
 var google_key = $x('P1_GOOGLE_KEY').value;
 var l_url = "http://maps.google.com/maps?file=api&v=2&key=" +
 google_key +
 "&sensor=false";
</script>I have tried, $v('P1_GOOGLE_KEY') , $x('P1_GOOGLE_KEY') , &P1_GOOGLE_KEY. and none of them work.
How do I access a page item from Javascript?
Thx!
Marc

Marc,
I am going to take a shot in the dark, but are you referencing this item outside of a function in your head tag? So basically it tries to reference the item on load? If so this is not going to work because the item does not exist yet. If you are using jQuery change your code to look like:
$(document).ready(function(){
 var google_key = $x('P1_GOOGLE_KEY').value;
 var l_url = "http://maps.google.com/maps?file=api&v=2&key=" +
 google_key +
 "&sensor=false";
});This will tell the javascript to fire after everything has fully loaded. If you are not using jQuery then you can use a little javascript snippet from here to add a ready event to your page. or you can copy paste this into a script tag.
(function () {
var ie = !!(window.attachEvent && !window.opera);
var wk = /webkit\/(\d+)/i.test(navigator.userAgent) && (RegExp.$1 < 525);
var fn = [];
var run = function () { for (var i = 0; i < fn.length; i++) fn(); };
var d = document;
d.ready = function (f) {
if (!ie && !wk && d.addEventListener)
return d.addEventListener('DOMContentLoaded', f, false);
if (fn.push(f) > 1) return;
if (ie)
(function () {
try { d.documentElement.doScroll('left'); run(); }
catch (err) { setTimeout(arguments.callee, 0); }
else if (wk)
var t = setInterval(function () {
if (/^(loaded|complete)$/.test(d.readyState))
clearInterval(t), run();
}, 0);
document.ready(function (){
var google_key = $x('P1_GOOGLE_KEY').value;
var l_url = "http://maps.google.com/maps?file=api&v=2&key=" +
google_key +
"&sensor=false";
Good Luck,

Set page item when going to single row view

Is there a possibility to set page items when going to single row view in an interactive report?
APEX 4.1
Edited by: Niels Delaere on Nov 21, 2011 4:59 AM

Thank you for your response, can you (or anyone else) give me a little more help? I can't seem to figure out how to get this working. The thing you are doing in your demo application is exactly what I want to do. Take two values of a certain row and set them in page items Where after in single row view users can see 3 additional regions with additional information based on these values.

Creating page items from pl/sql procedure and using them on a page

I have a page containing 2 select lists (P21_DEPARTMENTS and P21_DATE). Originally I added them as items that were "select list with submits". The problem is that based on the clearance level of the currently logged on user I only wanted the P21_DEPARTMENTS to be a select list if the user was an administrator. If however the user is not an admin then I want the page to have a hidden form field called P21_DEPARTMENTS that stores the user's department and has a label item that has the department name.
There is also a report region that generates a table based on the department selected from the select list (if the user is an admin) or the value stored in the hidden form field if the user is not.
My problem is that I cannot have both those items on the same page and use the HTML built-in authentication to determine which item should be rendered because I need to use the same ID for both items so that the stored procedure in my report region doesn't break. HTML does not permit items to share the same ID.
I tried to circumvent the problem by creating a stored procedure that performs all of the item rendering in the procedure and uses "htp.p()" to output all of my HTML code. This solution would allow me to pass a parameter into the procedure informing me as to whether or not the user is an administrator. If the user is an administrator the procedure would use a conditional statement and render a select list. If not, the hidden form field and label option would be used instead.
I finally got the stored procedure working perfectly. Now I am encountering the most bizarre thing. Since the "select list with submit" was not working (I used the same code that gets generated when I created other items using htmlDB's GUI) I decided to use a JavaScript function instead that gets triggered by the onChange event. I send along the value that is currently selected in the select list and in the function I set:
location.href='http://www.myoraclesite.com/pls/htmldb/f?p=111:21:729740000000000000::NO::P21_DEPARTMENTS:1';
In theory this should work. The problem is that it doesn't. The page reloads and the P21_DEPARTMENTS select list is not pre-selected.
The only thing I can think of is that when htmlDB generates page items that you've created with it's own admin tool it assigns some internal guid or something as opposed to when someone tries to generate dynamic page items of their own from a pl/sql procedure it's like the application doesn't even know they exist.
Any help would be GREATLY appreciated.
My only other solution would be to create a totally separate page (one for admin and another for non-admin). I would really like to avoid this.
Thanks in advance.

I would love to be able to generate my menus and
various other items in my htmlDB applications in much
the same way I can using ASP, PHP and Cold Fusion.
Users should have the ability to write server-side
code wherever they feel like it. The way htmlDB works
right now I spend more time trying to figure out how
to create simple effects and generate simple
interfaces when I need to be building a portal. Ami - it's important to understand that HTML DB is not like other languages. Thus, trying to force concepts which are common in other languages into HTML DB will often result in more work.
It's definitely worth the time to go over the HTML DB 2-day Developer, which can be found here: http://www.oracle.com/technology/products/database/htmldb/pdf/B14377_01.pdf
I can build a portal using Classic ASP, C#, PHP or Cold
Fusion in like 1/10 of the time that it takes me to
build one using htmlDB. I understand that this is not
meant for the hard-core programmer but no web
programming application in today's day and age should
prevent experts from getting under the hood.And I can build a Portal in HTML DB in 1/10 the time it will take me to do it in any other language. It's like anything else - proficiency comes with practice and work.
As for getting under the hood, there is plenty of places you can do that with HTML DB. Keep in mind that HTML DB itself is an HTML DB application, so the limits on what you can build with HTML DB are virtually limitless.
Sorry for the vent there. After spending the last 2
days trying to figure out how to implement such a
straightforward thing and now being informed that it
can't be done kind of bugged me.I understand your frustration, as I've been there before. My rule for beginners is that if you are writing more than a line or two of code in the first week, you're doing something wrong. Stop, take a break, and then use the ample resources (including searching this forum) to help solve your problem. There are plenty of resources available for you to learn about HTML DB on the HTML DB home page: http://otn.oracle.com/htmldb

Conditionally set page item based on value of another item

Hello,
I have a form that is used to create/apply changes to records. There is an application item (APP_ITEM_PROFILE)
that is set on login which contains a value for the user's Profile ID. This Profile ID is used through out the
application for authorizations (conditionally present tabs, etc).
I've set a page item on the form equal to APP_ITEM_PROFILE so that the record is stamped
with that user's profile ID when they create a record. Users with different Profile IDs may later make changes to
the record but I want to keep the original Profile_ID on the record.
I am trying to populate the Profile ID conditionally in the form based on the existence of a
record ID. If there is no ID (a new record is being entered), then I want the
Profile ID to be that of the current user (APP_ITEM_PROFILE). If there is an ID (modification is
being made to an existing record), then I want the keep the Profile ID that was originally saved
with the record in MyTable.
I have this as the source for :P11_PROFILE_ID. The type is PL/SQL Expression or Function, Always, replacing... but it
is not working (page not found when page is run):
begin
if :P11_ID is not null
then
select PROFILE_ID
into :P11_PROFILE_ID
from MyTable
where ID = :P11_ID;
elsif :P11_ID is null
then select nv(':APP_ITEM_PROFILE') into :P11_PROFILE_ID from dual;
end if;
end;
Item Descriptions:
ID is the record ID.
:P11_ID is the page item of the record ID (Display as Text, saves state).
PROFILE_ID is the user's Profile ID.
:P11_PROFILE_ID is the page item of the user's Profile ID.
:APP_ITEM_PROFILE is the user's Profile ID that is set on login.
Any help is greatly appreciated.
Thanks,
Matt
Update:
I found one of Scott's answers:
Using IF Else to determine the value of a Item
and modified the above code to:
declare l_ret number;
begin
if :P11_ID is not null
then
select PROFILE_ID
into l_ret
from MyTable
where ID = :P11_ID;
else select :APP_ITEM_PROFILE' into l_ret from dual;
end if;
return l_ret;
end;
It seems to be setting the Profile ID correctly when the ID is not null, but not when a new record is being created. In the latter case, there is no value.

Setting Session item from outside of APEX

Hi All,
First a little background: I've been learning APEX for a couple of days now. I'm evaluating it to see if it's suitable for the application we need to make, otherwise it'll be done in PHP.
The application needs to act as a web service client: as requirement number 1, we need to interface with a 3rd party IDP server to get a SAML2 assertion. This assertion will later need to be injected into the SOAP header of web service call, but I'm not worrying about this bit for now.
I've gotten half way there. I've created a new page with a process at runs before the header. This can handle creating our authn request (which is a bit of xml) and forward the browser onto the IPD server for authentication (with anthn request set as a GET parameter that has been deflated and base64 encoded). Whoo!
Once the IDP server has finished authenticating the user, a http post (with the SAML assertion we need) is done back to the application.
Now as I understand it, I can't get the IDP to post back to an APEX page directly, as we need to access the HTTP Post data. So, I plan on writing a PL/SQL procedure (which I've added to the FLOWS ok list to be called via the PL/SQL gateway).
So inside this procedure, I'm not in APEX, but I'll want to keep track of the SAML Assertion (which will just be a CLOB for arguments sake) such that I can use in APEX for when I make my SOAP call. If it was down to me, I'd have a table with session_id and the assertion, and just query that from APEX.
BUT this 3rd party that we have to work with is the government, and they've given us rules. We aren't allow to store these assertions, they can only exist in the scope of a users session (no storing in files, databases, anything that could be permanently stored on the hard drive), virtual memory is ok though.
So, after all that useless info, onto my question: Can I set an apex application item from this pl/sql procedure? If so, how would one do it? Now I understand that in the background, an item is probably written to a table, but I'm going to gloss over that for now (in the hope that the people certifying the app do the same).
Thanks for all the help,
Tim

Tim,
I am working a similar issue, but slightly different. I am trying to determine if we are trying to answer the same question.
Here is what I understand about your initial posting...
You are authenticating a user.. that must make a call to some "place".. then wait for that place to respond with an OK message, without storing the value. There is enough lag in this process that you want the response from "the place" that you want the response from "the place" to change the session value in the Web based UI. Is this correct?
Issue: Even if you did have this process setting the session value, the client web browser would not respond unless it was in some type of checking loop.
If you are in a checking loop, you would have the ability to call the "service" in some sort of checking mode from APEX.
If this is a smooth process (no major lag), you could manage it within a custom authentication scheme. Is this the area you are working in?
I understand your need to set from an outside connection. But if you are using the outside database connection method, you are isolated to a different session... I would believe (I do not work for Oracle) for security reasons.

Example of setting page item using javascript

Does anyone have an example of setting the value of a page item (hidden) using javascript? I have seen the following in the Forum but I am having trouble implementing it. If someone could show an example of a region it is called from, and the javascript (and where it is placed), that would be great.
I have tried something similar to this without luck so far:
function setValue(){
$x('P1_FIELD').value = 'Oracle';
Thanks!
John

Hi VS,
you should really use a "Set Value" dynamic action for that, that's much more transparent than using the onclick definition in the button attributes.

Set listbox items from web service response

Hi All
I am trying to set list box items from a web service response. Couple of issues over here:
1. The user should be able to select multiple items from the list. Hence if I set "Allow multiple values" and set Commit on "exit", then after the web service returns the output, no data is displayed in the listbox. I need to click inside the list box to see the data returned by the web service. How to overcome this..?? ( However this problem (clicking inside the listbox to see the items) does not exist if "Allow multiple values" is unchecked and Commit is set on "Select". )
2. After the list box is filled up, certain default values should be selected. This selection is based on one of the response field (which is actually a table with multiple values... ). Hence, how to capture this response field and set the default values in the above list..??
3. The same case for a dropdown. The values are visible in dropdown. However, a default value should be selected and displayed after returning a response from web service. Again, this default value is dependant on another field in the response as in point no.2
I am trying to use postExecute event as described in [this|http://forms.stefcameron.com/2009/03/23/pre-process-web-service-responses/] link...however not able to achieve the functionality. Please provide suggestions / inputs.
Thanks
Deepak

Hello,
first: I don´t know anything about the right solution. I am unaware of the existence of the solution, because there were quite many of question about this multiple selection problem and I don´t remember a single "answer".
I can recommend you to simplify everything and create the functionality yourself. I have done that before to avoid these "Adobe-standard" problems. If you have a problem with autofill of the object, ask your WS to send you a single string and pass it yourself using scripting (JS).
And if you have problems with multiple selection, create your own field/ object. Get the string of values, parse it, create multiple lines of the dynamic table with some suitable tool to check/ select the rows you need (use checkbox for example, and your text as a table row). This way you can selected anything you want with no problems at all. It wil only cost you some extra work.

Setting page items when tab pressed?

Does anyone know if you can set a page item when a standard tab is pressed on a page?
Dan

Or you might mean this:
On the page on which you want to set an item:
computation ->
add ->
item on this page ->
select all the appropriate values using "after submit" for the computation point ->
enter the computation static or dynamic value ->
condition type: request = expression1 (where expression1 is the name of your static tab -- ex: T_MYTAB)
You can also use one of the request !=, request in, request not in options for the condition type.

Xsql:set-page-param from multirow select into array variable

I'd like to set an XSQL page array variable to the result of a query that returns multiple rows.
Can I do something like this:
<xsql:set-page-param name="users[]">
select username from all_users
</xsql:set-page-param>
The documentation only mentions usage like
<xsql:set-page-param name="users[]" value="SCOTT SYS SYSTEM"/>

The set page param is only designed to look at the first column of the first row of its query results.
If you supplied a PL/SQL function that would return the list of users as a space-or-comma-separated string, then you could use:
select your_function() as user_list from dual
and then add the treat-list-as-array="yes" attribute to achieve this.
