How to get Value of tree node without Reload Page

hi,
i worked with apex 4.2 and i created Tree and tabular form to retrieve the date according the value of tree select node the code of tree something like this
select case when connect_by_isleaf = 1 then 0
when level = 1 then 1
else -1
end as status,
level,
"ENAME" as title,
null as icon,
"EMPNO" as value,
null as tooltip,
'f?p=36648:34:5234984107903::::P40_SELECTED_NODE:'||empno as link
from "DEPT"."EMP"
start with "MGR" is null
connect by prior "EMPNO" = "MGR"
order siblings by "ENAME
and i put Selected Node Page Item: P40_SELECTED_NODE . the tree worked good and retrieve the data into tabular form according to tree node value
my Question :
1- i want to retrieve the data without submit the page where each time i select value from tree make page reload to update the tabular form with new value ,there is any way to pass the value of tree node to P40_SELECTED_NODE item and refresh tabular form without page reload .
2- i want when selected from tree run page process according to value of tree node i tray to create Dynamic action with *(jquery selector : div.tree li>a)* but the Value of node incorrect.

How to get the view tree from a jsp page

Hi,
I would like to get the view tree of a jsp page. The idea is to dynamically include the content of one or more jsf pages into a UIPanel during a "value changed" event.
So, i could get from an arbitrary page like ...
<%@ taglib uri="http://java.sun.com/jsf/core"   prefix="f" %>
<%@ taglib uri="http://java.sun.com/jsf/html"   prefix="h" %>
<h:panelGrid columns="3" width="100%" rowClasses="gridTop">
    <h:outputText value="#{someBean.someValue}"/>
</h:panelGrid>... the corresponding List of components...
Any idea?

Thanks for your answer Jayashri,
The view tree can be retrieved by this way during the page is parsed, for example with scriptlets <%%>, or once the page has been parsed (the view has been builded and attached to the FacesContext).
My problem is to get the view tree of a page from another Context.
The idea is to build a dynamic layout of some pages that represents "views". I can imagine this like the concept of perspectives and views of Eclipse IDE.
Because of the difficulty to build it with pure JSP (cannot use dynamic ID nor JSTL ForEach), I try to build it into my backing bean and to bind it with a <h:panelGrid/>. By this way, I'm not able to use the <jsp:include/> tag as I usually did to include some content into the view tree.
Sorry for my english ;)

How to get value of yes/no on dailog page

All . Quick question right now the delete button delete's when the trashcan is hit. so I am adding a oadialog page ( code between _________________) to get a confirmation to proceed. i have the dialog page working. when delete button hit, confirmation page with Yes/No buttons show up. if i hit either one then the page goes back to my main page . the question is how do i return the value of the yes and no button to the code . this code is in the processFormRequest section. thanks for everyone's input . i really appreciate the help every one gives in this forum.
also . i got this from the delete tutorial excercise in oaf. i dont see where it returns the value to yes and no......
_________________Adding this _________________ _________________ _________________ _________________ _________________
OAException descMesg = new OAException("FND", "FND_CANCEL_ALERT"); //FND_CANCEL_WARNING

(this exists already in code and deletes the proper record when hit)

Serializable paramDelete[] ={actionInMainPersonScreen, paramPbId};
OAApplicationModule am = pageContext.getApplicationModule(webBean);
am.invokeMethod("deleteOrgMethod" , paramDelete);
}

Still having issue. i have the delete working and the dialog page working independently of each other. However I am still having a problem getting the value of the Dialog Page Yes or No Value. I am trying to say if value = "Yes" (or whatever the value of Yes button on Dialog Page) then I will Delete the record. Ive tried both Yes No DeleteYes and DeleteNo to get the value. I also used messages to see if its working.
So what am I missing and how do i get the value from the Yes / No button to return so i can code it in a if else statement . The previous post confirmed what i had already done (thanks for that answer). thanks to all for helping
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)

Urgent: How to get value from Element Node?

Hi All,
I have an xml like below:
<?xml version="1.0"?>
<Accounts>
<Account rowid="1">
<Account_Id>1</Account_Id>
<Customer_Id>1</Customer_Id>
<Account_Type>SB</Account_Type>
<Balance>1000.00</Balance>
</Account>
<Account rowid="2">
<Account_Id>2</Account_Id>
<Customer_Id>1</Customer_Id>
<Account_Type>CD</Account_Type>
<Balance>1000.00</Balance>
</Account>
</Accounts>
I am trying to get the value in the Account_Id element, but I am getting null everytime. Here is my code:
import com.sun.org.apache.xerces.internal.impl.xs.dom.DOMParser;
DOMParser parser = new DOMParser();
parser.parse("D:\\Temp\\PCORDBMS\\"+tableName+".xml");
Document doc = parser.getDocument();
NodeList nodes = doc.getElementsByTagName("Account");
for(int i=0;i<nodes.getLength();i++) {
Node fc=nodes.item(i).getFirstChild();
System.out.println(fc.getNodeValue());
I think, since fc node is of the type Element - getNodeValue() is not returning the value. I also tried getting child nodes, getting attributes for fc & then getNodeValue.
Am I missing something? Appreciate your help.
Thanks,
Niranjan

Hi Niranjan,
I used the JAXP DocumentBuilder and DocumentBuilderFactory classes. I use JSE 5.
Here's the complete code that works for me:
package com.trfsol.domtester;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
public class DomTester {
     * @param args
     public static void main(String[] args) {
          String filename = "C:\\Java workspaces\\Eclipse\\Workspace\\Test\\test.xml";
          try {
               // Parse XML file
               DocumentBuilderFactory factory =
                    DocumentBuilderFactory.newInstance();
               DocumentBuilder parser = factory.newDocumentBuilder();
               Document document = parser.parse(filename);
               // Get all "Account" nodes
               NodeList accountNodes = document.getElementsByTagName("Account");
               // Iterate over nodes
               for (int index = 0; index < accountNodes.getLength(); index ++) {
                    NodeList childNodes = accountNodes.item(index).getChildNodes();
                    for (int subIndex = 0; subIndex < childNodes.getLength(); subIndex ++) {
                         Node childNode = childNodes.item(subIndex);
                         System.out.println(childNode.getTextContent());
          catch (Exception e) {
               System.err.println("Exception: " + e.getMessage());

How to get the current tree element (node/childnode/childnode/...) ?

Hello!
I'm trying to create a kind of a navigation tree for my application.
It should represent some elements of an XML structure and some other nodes for other options.
The binding with the context is not a problem, I can create the tree up to all the levels I want to.
The problem now is, that I don't know, how to get the "current tree element", when there is any action.
For example:
public void onActionSelect(...) {
String test = wdContext.currentTreeNodeElement().getText();
wdThis.wdGetContext().currentContextElement().setSelectedElement(test);
With this method I can get the text of the "first level nodes". If I want to get the "second level node", I can do
String test = wdContext.currentTreeNodeElement().currentChildElement.getText();
..and for the next levels so on.
Isn't there any general method to get the information of the selected element without knowing before, whether it is a nodeElement or a nodeElement.currentChildElement or a nodeElement.currentChildElement.currentChildElement, ...?
Greetings,
Ramó

Hi,
if you following that pdf ,
i think your not implemented the below code in DomodifyView method
if (firstTime) {
      IWDTreeNodeType treeNode = (IWDTreeNodeType) view.getElement("TheNode");
      /* The following line is necessary to create parameter mapping from parameter "path" to parameter "selectedElement".
Parameter "path" is of type string and contains the string representation of the tree element (its corresponding context element to be exact)
that raised the onAction event. Parameter "selectedElement" is of type IWDNodeElement (or extends it) and is defined as parameter in the event handler
that handles the onAction. The parameter mapping defined here translates the String "path" into the corresponding context element that then can
be accessed within the event handler
      treeNode.mappingOfOnAction().addSourceMapping("path", "selectedElement");
      /* The following line is necessary to create parameter mapping from parameter "path" to parameter "element".
Parameter "path" is of type string and contains the string representation of the tree element (its corresponding context element to be exact)
that raised the onLoadChildren event. Parameter "element" is of type IWDNodeElement (or extends it) and is defined as parameter in the event handler
that handles the onLoadChildren. The parameter mapping defined here translates the String "path" into the corresponding context element that then can
be accessed within the event handler
      treeNode.mappingOfOnLoadChildren().addSourceMapping("path", "element");
please cross check once.
Thanks,
Ramesh

How to get values/data stored in the database into a list-item.

how to get values/data stored in the database into a list-item.
i tried to make a list item without any values assigned to it...but i got the below error.
FRM-30191: No list items defined for required poplist.
or
FRM-32082: Invalid value for given item type.
List EMPNO
Item: EMPNO
Block: EMP
Form: MODULE5
FRM-30085: Unable to adjust form for output.
then according to some docs, i tried the the following for the trigger
when-new-form-instance
declare
     rg_name varchar2(40) := 'emp_rec';
     status number;
     groupid recordgroup;
     it_id item;
begin
     it_id := Find_Item('empno');
     groupid := create_group_from_query(rg_name, 'select empno from emp');
     status := populate_group(groupid);
     populate_list(it_id, groupid);
end;
but yet didnt work... :(
so how the heck do i get values fetched from the database table into the list item?

for list items you need to values in the record group, one is the shown value and one is the returned value.
Check out the online help for the populate_list built-in.
You'll need something like select ename,ename from emp as the record group query.

How to get current version of safari. without having safari browser?

how to get current version of safari. without having safari browser?

I don't understand the question. Safari is a browser.
Can you elaborate on what your are trying to do that initiated the question? People may be able to come up with some other option that gets you working the away you want.
When you respond, please post the version of the Mac OS and the version of Safari you currently have. Otherwise, people are guessing and the quailty of help you get plummets.

How to get value of URL parameter

Hi,
If an ABAP Web Dynpro URL looks like this: http://<server>:<port>/sap/bc/webdynpro/sap/zny_test1?sap-client=100&sap-language=EN, how to get value of the URL parameter sap-client at runtime in the application?
Thanks,
Nancy

The framework currently strips all the framework specific params.
Perhaps the will be made available in a future release. Thomas, any comments ?
However, I dont understand the requriement to know the sap-client URL value.
If your code is running, a user has successfully connected to system a therefore he has a session open and this session is associated with exactly 1 client at any point in time.
See SYSTEM VARAIBLE SY-MANDT.
this represents the client in which the users session is running and negates the need to see
sap-client URL value.

How to get List Item attachments name without write any custom code or any database query?

Hi,
How to get List Items attachments name without write any custom code or any database query?

You can get it from Rest,
There are 2 options,
1) create a 'Result Source' which has a search query for that List which has attachments
- Use rest query to get the 'Filename' , it will have the attachment file name
For example, if the result source id is : 73e6b573-abf8-4407-9e5f-8a85a4a95159 , then the query will be
http://[site URL]/_api/search/query?querytext='*'&selectproperties='Title,Path,FileExtension,SecondaryFileExtension,Filename'&sourceid='73e6b573-abf8-4407-9e5f-8a85a4a95159'&startrow=0&rowLimit=100
You can refine the query, be giving proper 'querytext'
2) Use the List rest api
For example if your list guid is :38d524a1-e95c-439f-befd-9ede6ecd242e
You can get he attachments for 1st item using this
http://[Site URL]/_api/lists(guid'38d524a1-e95c-439f-befd-9ede6ecd242e')/items(1)/AttachmentFiles

How to get value of html combo box (i.e select) in jsp?

Hello,
I was just wondering how to get value of html combo box in jsp page. My code for combo box is:
<select name="combo" size="1">
<%
List<Project> projects = mgr.getProjects();
for(Project project : projects){
%>
<option value="<%= project.getId()%>"><%= project.getName()%></option>
<%
%>
</select>
I thought combo.value might give me the value, but it throws exception.
Any help is appreciated.
Thanks.

The combo does not exists in Java, but only in HTML. You have to submit the form containing the combo and then use request.getParameter("combo") to get it's value ;-)

How to get value of a textfield which has been set as Renderd false.

Hi all
how to get value of a TEXTFIELD which has been set as Renderd false.
i am getting the value of this textfield from an lov but dont want to show it to the user.
getting error as:
attribute xxxx required for view object yyyyy.
pls help
naveen

You can create item inside your LOV region, set the item style to formValue. You can associate this to a View Object field. It can also act as mirror of any other text input field.
FormValue can hold the value and will not be diaplyed to user. You can read value from it controller
example
OAFormValueBean orgValue = (OAFormValueBean)webBean.findChildRecursive("OrgIdFormVal");
Or you can read it fro the VO associated with this form value.
