Update collection using ajax

could anyone tell me how can I implement the update collection using ajax? I saw the example from carl's wonderful solution for "collection control" but he didn't implement update and delete single record. I am trying to make it, but i stoped at the point to auto assign the item value to update statements. I don't know how can I get the value immediately when I change it. Thanks in advance.

Karen,
did you find any solution for this problem?
I am struggling with a similar problem.
I found out that the seq_id is not available, which results in the error "no data found".
At the moment, I don't see how to provide the seq_id correctly.

Invalid table name error when updating object in collection using SQL

Hi,
I have pl/sql code where I am selecting a object from a collection using sql select query. I am processing this record and now I want to update the collection with the new object. ie. ensure that the object that was fetched be removed and this new one be added.
considering my_ot is the object type and my_tt is the table type.
DECLARE
my_col my_tt;
my_col1 my_tt
my_var my_ot;
my_var2 VARCHAR2(10);
BEGIN
// populating my_col1 with select query
//populating my_col with select query
FOR my_col1.FIRST .. my_col.LAST LOOP
//populating my_var2
BEGIN
SELECT my_ot(c.field1, c.field2 ,c.field3) INTO my_var FROM TABLE(my_col) c WHERE c.field3 = my_var2
//processing the field my_VAR
UPDATE TABLE(my_col) c SET c.field1 = my_var.field1 , c.field2 = my_var.field2 , WHERE c.field3 = my_var.field3;
EXCEPTION WHEN NO_DATA_FOUND
my_col.EXTEND;
my_col(my_col.LAST) := // new my_ot object
END;
END LOOP;
Here, when compiling the update query is not being compiled. I am getting a error 'invalid table name'. Is there any way to modify an object in the collection without knowing its index?
If not, is it possible to find the index of a object in the collection in select query?
Thanks in advance
Paddy

Hi,
Is there any way to find the index of a object in the collection? Then I will simply replace the object at that index, right!
Thanks
Paddy

SharePoint 2013 RSS Viewer not loading when other Custom web part using Update Panel or Ajax Timer control

Hi,
SharePoint 2013 RSS
Viewer web part failing to complete loading when the page loads.
This happens when having RSS Viewer and then adding a Custom webpart with an updatepanel and timer control.
I had used Ajax update panel and timer control to load the web part asynchronously after the main page is fully loaded.
The RSS-Viewer web part hangs in loading state while the custom webpart loads just fine.
The issue occurs when an like button click or Timer Tick event fires after the page
is loaded.
Haven't been able to track the issue.
Couple of workaround I tried to call a server side button click event from the custom web part after the page gets fully loaded using JQuery shown below did not work out either.
$(document).ready(function () {
$('#<%= netButton2.ClientID %>').click();
And
document.onreadystatechange = function () {
if (document.readyState == "complete") {
$('#<%= netButton2.ClientID %>').click();
Please let me know how to resolve this issue.
Thanks,
Franklin

Hi Johan,
The assignment of this user on the given task might be corrupted. Try to remove the resource from the task, publish the project, assign the resource again and publish again the project. If it is not working, try to unpublish the task (column "publish")
and publih it again.

How to use Ajax Get Multiple Values in Tabular form?

Hi All-
I am trying to use AJAX to get multiple values in tabular form by using Denes Kubicek's example in the following link -
http://apex.oracle.com/pls/otn/f?p=31517:239:9172467565606::NO:::
Basically, I want to use the drop down list to populate rest of the values on the form.
I have created the example(Ajax Get Multiple Values, application 54522) on Oracle site -
http://apex.oracle.com/pls/apex/f?p=4550:1:0:::::
Workspace: iConnect
login: demo
password: demo
I was able to duplicate his example on page 1 (home page).
However, I want to use system generate tabular form to finish this example, and was not able to populate the data correctly.
Page 2 (method 2) is the one that I am having trouble to populate the column values. When I checked application item values in Session, and the values seems to be populated correctly.
This is what I have done on this page:
1. Create an Application Process On Demand - Set_Multi_Items_Tabular2:
DECLARE
v_subject my_book_store.subject%TYPE;
v_price my_book_store.price%TYPE;
v_author my_book_store.author%TYPE;
v_qty NUMBER;
CURSOR cur_c
IS
SELECT subject, price, author, 1 qty
FROM my_book_store
WHERE book_id = :temporary_application_item2;
BEGIN
FOR c IN cur_c
LOOP
v_subject := c.subject;
v_price := c.price;
v_author := c.author;
v_qty := c.qty;
END LOOP;
OWA_UTIL.mime_header ('text/xml', FALSE);
HTP.p ('Cache-Control: no-cache');
HTP.p ('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn ('<body>');
HTP.prn ('<desc>this xml genericly sets multiple items</desc>');
HTP.prn ('<item id="f04_' || :t_rownum || '">' || v_subject || '</item>');
HTP.prn ('<item id="f05_' || :t_rownum || '">' || v_price || '</item>');
HTP.prn ('<item id="f06_' || :t_rownum || '">' || v_author || '</item>');
HTP.prn ('<item id="f07_' || :t_rownum || '">' || v_qty || '</item>');
HTP.prn ('</body>');
END;
2. Create two application items - TEMPORARY_APPLICATION_ITEM2, T_ROWNUM2
3. Put the following in the Page Header:
<script language="JavaScript" type="text/javascript">
function f_set_multi_items_tabular2(pValue, pRow){
    var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
'APPLICATION_PROCESS=Set_Multi_Items_Tabular2',0);
if(pValue){
get.add('TEMPORARY_APPLICATION_ITEM2',pValue)
get.add('T_ROWNUM2',pRow)
}else{
get.add('TEMPORARY_APPLICATION_ITEM2','null')
    gReturn = get.get('XML');
    if(gReturn){
        var l_Count = gReturn.getElementsByTagName("item").length;
        for(var i = 0;i<l_Count;i++){
            var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
            var l_ID = l_Opt_Xml.getAttribute('id');
            var l_El = html_GetElement(l_ID);
            if(l_Opt_Xml.firstChild){
                var l_Value = l_Opt_Xml.firstChild.nodeValue;
            }else{
                var l_Value = '';
            if(l_El){
                if(l_El.tagName == 'INPUT'){
                    l_El.value = l_Value;
                }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
                    l_El.parentNode.innerHTML = l_Value;
                    l_El.parentNode.id = l_ID;
                }else{
                    l_El.innerHTML = l_Value;
    get = null;
</script>
Add the follwing to the end of the above JavaScript:
<script language="JavaScript" type="text/javascript">
function setLOV(filter, list2)
var s = filter.id;
var item = s.substring(3,8);
var field2 = list2 + item;
f_set_multi_items_tabular2(filter, field2);
4. Tabular form query:
select
"BOOK_ID",
"BOOK",
"SUBJECT",
"PRICE",
"AUTHOR",
"QTY",
"BOOK_ID" BOOK_ID_DISPLAY
from "#OWNER#"."MY_BOOK_STORE"
5. In Book_ID_DISPLAY column attribute:
Add the following code to element attributes: onchange="javascript:f_set_multi_items_tabular2(this.value,'#ROWNUM#');"
Changed to -> onchange="javascript:setLOV(this,'f03');"
Now, T_ROWNUM2 returns value as f03_0001. But, TEMPORARY_APPLICATION_ITEM2 returns as [object HTMLSelectElement]...
Please help me to see how I can populate the data with this tabular form format. Thanks a lot in advanced!!!
Ling
Updated code in Red..

Ling
Lets start with looking at what the javascript code is doing.
function f_set_multi_items_tabular(pValue, pRow){
/*This will initiate the url for the demand process to run*/
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
                          'APPLICATION_PROCESS=Set_Multi_Items_Tabular',0);
if(pValue){
    /*If there is an value than submit item name with value*/
    get.add('TEMPORARY_APPLICATION_ITEM',pValue)
    get.add('T_ROWNUM',pRow)
}else{
    /*Else set the item TEMPORARY_APPLICATION_ITEM to null*/
    get.add('TEMPORARY_APPLICATION_ITEM','null')
/*Submit the url and te returned document is of type XML*/
gReturn = get.get('XML');
if(gReturn){
    /*There is something returned*/
    var l_Count = gReturn.getElementsByTagName("item").length;
    /*For all elements of the tag item*/
    for(var i = 0;i<l_Count;i++){
      /*Get the item out of the XML*/
      var l_Opt_Xml = gReturn.getElementsByTagName("item")[i];
      /*Get the id of the item*/
      var l_ID = l_Opt_Xml.getAttribute('id');
      /*Get the element in the original page with the same id as
      **the item we have in the XML produced by the ondemand process
      var l_El = html_GetElement(l_ID);
      /*Now get the value of the item form the XML*/
      if(l_Opt_Xml.firstChild){
        var l_Value = l_Opt_Xml.firstChild.nodeValue;
      }else{
        /*There is no value*/
        var l_Value = '';
      if(l_El){
        /*There is an element with the same id as the item we are processing*/
        if(l_El.tagName == 'INPUT'){
          /*The element is an input item just set the value*/
          l_El.value = l_Value;
        }else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
          /*If it is a span elment and has the class grabber
          **Then set the innerHTML of the parent to the value
          **and the id of the parent to the id
          l_El.parentNode.innerHTML = l_Value;
          l_El.parentNode.id = l_ID;
        }else{
          /*Else set the value as innerHTML*/
          l_El.innerHTML = l_Value;
get = null;
Now where it went wrong in your initial post
The XML that was returned by your XML process would be something like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_1">CSS Mastery</item>
<item id="f03_1">22</item>
<item id="f04_1">Andy Budd</item>
<item id="f05_1">1</item>
</body>
When you don't use apex_item to create your tabular form a item in the table will look like
<input id="f02_0001" type="text" value="CSS Mastery" maxlength="2000" size="16" name="f05" autocomplete="off">
Notice the id's f02_1 and f02_0001 don't match.
So to make it work the XML would have to look like
<body>
<desc>this xml genericly sets multiple items</desc>
<item id="f02_0001">CSS Mastery</item>
<item id="f03_0001">22</item>
<item id="f04_0001">Andy Budd</item>
<item id="f05_0001">1</item>
</body>
To do that simply use lpad in the ondemand process like
HTP.prn ('<item id="f02_' || lpad(:t_rownum,4,'0') || '">' || v_subject || '</item>');
HTP.prn ('<item id="f03_' || lpad(:t_rownum,4,'0') || '">' || v_price || '</item>');
HTP.prn ('<item id="f04_' || lpad(:t_rownum,4,'0') || '">' || v_author || '</item>');
HTP.prn ('<item id="f05_' || lpad(:t_rownum,4,'0') || '">' || v_qty || '</item>');
Keep in mind that the above is based on your original post and #ROWNUM# not being lpadded with zero's.

How to add a new record in updatable report using apex_item

Hi,
i am using an updatable report using the following select
select
aPEX_ITEM.POPUP_FROM_QUERY(2,emp_code,
' SELECT emp_surname, emp_code FROM hrm_employee ' ,null,null,null,null,null,'onchange="f_set_multi_items_tabular(this.value ''#ROWNUM#'''

100,
'style="width:190px" ',
'f11_' || '#ROWNUM#'
) Name,
" REST_DATE",
"REMARKS",
from "roster"
when i click on the button add row , only the column rest_date and the remarks are enable.
why is the apex_item.text and apex_item_popup_from_query is disable ? and how i can make it enable.
thanks
regards
jerry

I could see that you are using the addRow() function to generate new blank row.
I guess, this function(used by the builtin tabular form s) , identifies editable columns when they are marked so at the report column attributes.
When you use apex_item API, it expects the columns to be standard report column and hence render the new rows as such.
Some one from the development team might be able to give a better answer on that.
As for avoiding this issue
<li>One method , would be to define the columns editable(and display types) in report column attributes.
<li> You can duplicate the last row using jQuery( *$('tr.highlight-row:last).after( $('tr.highlight-row:last).clone() )* ) and removing the field values, but events(for example datepicker) would remain attached to the original row , so it isn't very straightforward either.
<li>If you want to use apex_item you would have to use a pseudo union to DUAL for generating a blank row and re-render the report either by a page load or a Dynamic Action. Sounds like a nice idea for a plugin.
Now , if you want to add rows multiple times without saving them, then you would need to store the values in a collection at load and update the collection before adding the row.

Error processing a page when using AJAX

hi apex forum.
I need your help with a problem that presents me with an application in apex 4.2.
I have developed a html screen, in which I have created a table that contains a detailed items and on which the user can enter some values. these data that user enters, I calculate a total at the end of the page. To view the current total of the entries , the user presses a button that uses AJAX (to avoid having to refresh the whole page) to calculate totals and at the same time, i call an AJAX process to add each record to an apex_collection , until here everything perfect.
The problem is that when I want to save the information to pass it from apex_collection to the database (by pressing a button and make the official insert), I must first have to refresh the page, if not do it this way, Apex generate an Error Message.
it's important to say that error does not apper, if before pressing the button, i first refresh the page. Any suggestions??
I think I should use some internally command to synchronize or update the page.... any suggestions are welcome.,
thanks in advance,

Soooo...
What is the error you are seeing?
Is the multi-row process still there? What exactly happens on submit (computations, validations, processes)?
Have you tried to run with debug enabled and were you able to see where the error originates?

Using AJAX to call a method of controller.

I am working with weblogic 10.2 .I need to call a method of the controller using Ajax (because i don't wan to refresh the whole page).
I am new to Ajax.
Can any one provide me the stub or prototype for calling a method of contoller from jsp using AJax.

Another approach, if you would like to call a Pageflow action and then update only a portion of a portlet with the result, would be to use the Dynamic Content taglib.

Help required for using ajax in netweaver

Hi..
Can i Use Ajax for my netweaver applications?? If yes, then how?? Any pointers regarding that will be adequately rewarded points..
Thanks

For pure JavaScript enabled AJAX application, no problem. You just write the application as usual and send XMLHttpRequest with parameters to server, then update the web page with your JavaScript code;
I can show you some sample code here:
<script type="text/javascript">
        function createXMLHttpRequest() {
             var xmlHttp;
            if (window.ActiveXObject) {
                    xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
            else if (window.XMLHttpRequest) {
                    xmlHttp = new XMLHttpRequest();
            return xmlHttp;
        function onclick_changeModelHouse(id) {
            var xmlHttp = createXMLHttpRequest();
            xmlHttp.onreadystatechange = function(){
                 if(xmlHttp.readyState == 4) {
                      if(xmlHttp.status == 200) {
                           // here you get your page component with id or any you like,
                                // then update it with data returned from the request you sent;
                               // Here I update one image url path;
                              var img = document.getElementById("houseModel");
                               // suppose you return the image file name;
                     img.innerHTML="<img src='images/" + xmlHttp.responseText + "'>";
            xmlHttp.open("GET", "http://myserver:8080/myApp//AjaxImageService?model="+id, true);
            xmlHttp.send(null);
</Script>
For some button in your page you add javascript code like
onClick="onclick_changeModelHouse(id)"
somthing.
You need develop servlet to response your request, and usually you need pass back your data in XML format, here I just use plain text for easy understanding.

How to update collection when checkbox changed in report

I have a report based on a collection:
select seq_id
       ,c001
       ,c002
       ,apex_item.checkbox(1,seq_id,decode(c003,'J','CHECKED','UNCHECKED')) selected
from apex_collections
where collection_name='CONCOLLECTION'When the checkbox changes I want to store the new checked/unchecked status in the collection.
Steps towards a solution I've come up with:
1 Create a dynamic action: Change, jquery selector : input[name="f01"]
2 Create javascript to store value (=seq_id) of changed item into a hidden page item.
3 plsql code to update collection member with seq_id that is now in hidden item.
Is this the way to do it?
If so, it's the javascript of step 2 that I can't figure out.
thanks, René

thanks this works.
Using javascript I store the seq_id and the checked value in 2 page items
$s('P70_SEQ_ID', $(this.triggeringElement).val() );
$s('P70_CHECKED', $(this.triggeringElement.checked).val() );The checked value I get is <empty> when checked and 'undefined' when unchecked. Based on this I can now update the collection.
declare
l_selectie varchar2(1);
begin
if v('P70_CHECKED')='undefined'
then
    l_selectie := 'N';
else
    l_selectie := 'J';
end if;
apex_collection.update_member_attribute(p_collection_name => 'CONCOLLECTION'
                                             ,p_seq             => v('P70_SEQ_ID')
                                             ,p_attr_number     => 3
                                             ,p_attr_value      => l_selectie);
end;

I just drag and drop the Ajax update panel in aspx page that used in custom field solution. then i just run the code and see the result on the new form in the custom list. so i dont think, we need to do more work on this.
Thanks,

Example: Cascading Popup LOVs (Solution using Ajax)

If you need popup LOVs to depend on each other, here's a way to do it:
Put this in the header text of the page:
<script type="text/javascript">
function clearFormData(data) {
var items = new Array();
items.push(data);
for (var i = 0; i < items.length;i++) {
var item = items;
document.getElementById(item).value = '';
if (document.getElementById(item+'_HIDDENVALUE')) document.getElementById(item+'_HIDDENVALUE').value = '';
return true;
function setSessionData(data) {
var get = new htmldb_Get(null,document.getElementById('pFlowId').value,null);
var items = new Array();
items.push(data);
for (var i = 0;i < items.length;i++) {
var item = items[i];
var tempObjID = (document.getElementById(item+'_HIDDENVALUE')) ? item+'_HIDDENVALUE' : item;
get.add(item, document.getElementById(tempObjID).value);
get.get();
return true;
</script>
These are some helper functions (makes it easier to port to other pages, you could also put them in an external js file).
Now on the second (or whatever) popup LOV (one that needs the value of another), put following code into the field "Form Element Option Attributes":
[i]onclick="setSessionData('P1_FIRST_POPUP')"
Change "P1_FIRST_POPUP" into the id/name of the popup LOV that the second depends on.
Now to clear the second one (if there is already something in it) you can put this into the "Form Element Option Attributes" field of the first popup LOV:
onclick="clearFormData('P1_SECOND_POPUP')"
Change the "P1_SECOND_POPUP" into the id/name of the popup LOV that depends on the first one.
If you need more than one item to be set in the session use the javascript functions like this:
onclick="setSessionData(['P1_FIRST_POPUP','ANOTHER_ITEM';'AND_SO_ON'])"
onclick="clearFormData(['P1_SECOND_POPUP','ANOTHER_ITEM';'AND_SO_ON'])"
This is the best solution I figured out so far for cascading popups.
Demo: http://apex.oracle.com/pls/otn/f?p=36908:2
If you need cascading select boxes it's better to use this solution: http://apex.oracle.com/pls/otn/f?p=11933:37 .
Edit:
- works now regardless of being logged in or not, I just forgot to take ou the 0 in the htmldb_Get call (=> always
sent the session id "0", which didn't exist)
- added a link to the demonstration

excellent tip for using ajax to update session state.
one small change to share:
function setSessionData() {
var get = new htmldb_Get(null,document.getElementById('pFlowId').value,null,null);
for (var i = 0; i < arguments.length; i++) {
var item = arguments\[i\];
var tempObjID = (document.getElementById(item+'_HIDDENVALUE')) ? item+'_HIDDENVALUE' : item;
get.add(item, document.getElementById(tempObjID).value);
get.get();
return true;
set 4th argument to htmldb_Get constructor to null.. causes the script to retrieve the value from the hidden form field, rather than being set explicitely.
just noticed this code is different from the demo, which does set a static value of 2. Tempted to hit cancel, but maybe this can avoid someone else a lot of head scratching.
also, was having issues with Array.push() during debugging to find the above issue.. and changed the way html form element id(s) are passed to the function; opted to use the implicit "arguments" array instead. Minor, but worth noting.
thanks again for the useful piece of code.
edit:
this wiki doesn't parse brackets well; added char escapes so they'll show.. will need to remove by hand.

Parameter passing using ajax

hi,
I am trying to pass more than one parameter while sending the form to the action class using the ajax technology in struts, but unable to do tha.
Can anyone suggest any way for that.
Moreover, Can anyone tell does the form gets submitted when page is updated using ajax technology. If the form gets submitted, i can retrieve the values in the action class.
My code in the js file is like that:
var url = "DynamicXYZAction.do?strLimitLevel=" + escape(strLimitLevel)+"&strBusiness="+escape(strBusinessId);

Send the parameter values with the request url.

Values having html tags not getting populated while using AJAX in APEX

for(var i = 0;i<l_Count;i++){
var l_Opt_Xml = gReturn.getElementsByTagName("item");
var l_ID = l_Opt_Xml.getAttribute('id');
var l_El = html_GetElement(l_ID);
if(l_Opt_Xml.firstChild){
var l_Value = l_Opt_Xml.firstChild.nodeValue;
}else{
var l_Value = '';
if(l_El){
if(l_El.tagName == 'INPUT'){
l_El.value = l_Value;
}else if(l_El.tagName == 'SPAN' && l_El.className == 'grabber'){
l_El.parentNode.innerHTML = l_Value;
l_El.parentNode.id = l_ID;
}else{
l_El.innerHTML = l_Value;
get = null;
</script>
And I have the application process as follows
BEGIN
OWA_UTIL.mime_header ('text/xml', FALSE);
HTP.p ('Cache-Control: no-cache');
HTP.p ('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn ('<body>');
HTP.prn ('<desc>this xml genericly sets multiple items</desc>');
HTP.prn ('<item id="f05_000' || :T_ROWNUM || '">' || :TEMPORARY_APPLICATION_ITEM || '</item>');
HTP.prn ('</body>');
END;
If I have :TEMPORARY_APPLICATION_ITEM as 'Vikas' it gets displayed properly but if I have '<b>Vikas<b>' it shows null. if it has any HTML tags function l_Opt_Xml.firstChild.nodeValue is not working properly .Please tell me what modiifcation can I use in function l_Opt_Xml.firstChild.nodeValue to get Values with HTML tags also to get displayed.
Thanks,
Vikas

Vikas,
Try escaping special characters: htf.escape_sc(:TEMPORARY_APPLICATION_ITEM)Regards,

Loading complex report data into a direct update DSO using APD

Dear All,
Recently, I had a requirement to download the report data into a direct update DSO using an APD. I was able to perform this easily when the report was simple i.e it has few rows and columns. But I faced problems If the report is a complex one. Summing up, I would like to know how to handle the scenarios in each of the following cases:
1.   How should I decide the key fields and data fields of the direct update DSO ? Is it that the elements in ROWS will go to the
      key fields of DSO and the remaining to the data fields? Correct me.
2.   What if the report contains the Restricted KFs and Calculated KFs? Do I have to create separate infoobjects in the BI
      system and then include these in the DSO data fields to accommodate the extracted data ?
3.   How do I handle the Free Characteristics and Filters ?
4. Moreover, I observed that if the report contains selection screen variables, then I need to create variants in the report and
     use that variant in the APD. So, if I have 10 sets of users executing the same report with different selection conditions, then
     shall I need to create 10 different variants and pass those into 10 different APDs, all created for the same report ?
I would appreciate if someone can answer my questions clearly.

Hi ,
PFB the answers.
1. How should I decide the key fields and data fields of the direct update DSO ? Is it that the elements in ROWS will go to the
key fields of DSO and the remaining to the data fields? Correct me.
--- Yes , you can use the elements in the ROWS in the Key fields, but in case you get two records with same value in the ROWS element the data load will fail. So you basically need to have one value that would be different for each record.
2. What if the report contains the Restricted KFs and Calculated KFs? Do I have to create separate infoobjects in the BI
system and then include these in the DSO data fields to accommodate the extracted data ?
Yes you would need to create new Infoobjects for the CKF's and RKF's in the Report and include them in your DSO.
3. How do I handle the Free Characteristics and Filters ?
The default filters work in the same way as when you yourself execute the reoprt. But you cannot use the Free characterisitics in the APD. only the ROWS and cloumns element which are in default layout can be used.
4. Moreover, I observed that if the report contains selection screen variables, then I need to create variants in the report and
use that variant in the APD. So, if I have 10 sets of users executing the same report with different selection conditions, then
shall I need to create 10 different variants and pass those into 10 different APDs, all created for the same report ?
--- Yes you would need to create 10 different APD's. Its very simple to create, you can copy an APD. but it would be for sure a maintance issue. you would have to maintain 10 APD's.
Please revert in case of any further queries.
