How to get the Component id (HTMLB id)

Hi all,
I created an application that has two list boxes and one commend button. While clicking the button I need to know how many list items in the list box. Is this possible?
Anybody can guide me for this.
Helpful answer will appreciate.
Thanks & Regards,
Kathiresan R

hi,
In case you are using HTMLB controls what you are looking for is posible...
Do the below mentioned way...
As you need to get the number of items inside the selected list box on action of a button, it means first you need to catch the action generated by the button...
So inside your button, under button tage you can add/have a property called "OnClick("Method Name")"...
so now you define the method inside your controller...
public void method_Name(Event event)
//first het the list box ID:
ListBox lb=(ListBox)this.getComponentByName("Your_ListBox_Name");
now with ID
you can do,
int size=lb.getSize() //Returns the number of elements inside the list box...
for more information please have a look at the below thread...

F2 on Popups? (Or how to get the Component if F2 is not working)

Hello Experts,
I wonder if somebody has a tip how to get the component of popups?
The F2 Help is not working there.
The Popup I'm actually looking at is called by a button. Is it possible to find out the called component by looking at the button Event? (I have tried - but the source does not tell me any component)
Thanks for answers...
Regards
Chris

Chris,
F2 should definitely work if it is a UI component.
You see pop ups on button clicks and F4 value helps. F2 should work in these cases.
For some attributes with F4 help, a DDIC search help is attached. Here F2 does not work.
Anyhow to find out which component it is calling, you use this method
check in the event handler(for button pop ups) or in the outbound plugs specifies in GET_V method(for F4 pop ups) if there is a code like
CALL METHOD comp_controller->window_manager->create_popup etc.,
A Component Usage will be passed to the method. You can check for the component usage in the Run Time Repository.
You will get the component details.

        text: "Log On"
        font: Font {size:11 name: "Verdana Bold"}
        action: function() {
            showHello();
function showHello(){
   // add a label in index.fx whose text is "welcome!";
    }I want to show something on the index.fx but I don't know how to get the parent from the child component?
In Flex, we use parent or parentApplication, Is there a similar function in JavaFX?

Reusing the same Tile example, I had no problems, I suppose I was doing wrong the first time:
def IMAGES_WIDTH = 100;
def IMAGES_HEIGHT = 100;
var COLUMN_NB = 3;
var ROW_NB = 3;
var scene: Scene;
var previews: Container;
Stage
title: "Test of Tile layout"
scene: scene = Scene
    width: 500
    height: 500
    fill: Color.LAVENDER
    content:
      previews = Tile
        hgap: 10
        vgap: 10
        layoutX: bind (scene.width - previews.width) / 2
        layoutY: bind (scene.height - previews.height) / 2
        columns: COLUMN_NB
        content: for (i in [ 1 .. COLUMN_NB * ROW_NB ])
          ImageView
            id: "IV{i}"
            image: Image
              url: "{__DIR__}clock.gif"
              width: IMAGES_WIDTH
              preserveRatio: true
            onMousePressed: Hide
function Hide(evt: MouseEvent): Void
println("{evt.node} ({evt.node.id}) - {evt.node.parent}");
var nm: Node = evt.node.parent.lookup("IV5"); // Middle node
nm.visible = false;
var ntl: Node = evt.node.parent.lookup("IV1"); //Top left node
(ntl as ImageView).viewport = Rectangle2D { height: IMAGES_WIDTH/2, width: IMAGES_WIDTH/2 };
(evt.node.parent as Tile).hgap = 20; // Strange effect, but works

How to get the local file system path of an image that loaded into the image component in cq5?

Hi,
I'm having hard time uploading image from filesystem where as drag and drop works.
I'm not getting a path of image selected from filesystem.
here is my code..
private String populateImage() throws Exception {
                    if (currentNode != null && currentNode.isNode()) {
                                   Node ImageNode = JcrResourceUtil.createPath(currentNode, "image",
                                                                      null, "nt:unstructured", true);
                                   imageUrl = ImageNode.hasProperty("fileReference") ? ImageNode.getProperty("fileReference").getValue().getString() : "";
       imageUrl = imageUrl.trim();
        log.info("MANAGE PROFILE BEAN IMAGE URL INSIDE IF IS: " + imageUrl);
                    } else {
                                        imageUrl = properties.get("fileReference", "");
                                        imageUrl = imageUrl.trim();
                                        log.info("MANAGE PROFILE BEAN IMAGE URL INSIDE ELSE IS: " + imageUrl);
                    return imageUrl;
So if I drag and drop..
ImageNode.hasProperty("fileReference") is returning a valid path
but if I upload an image it is returning Null.
So how to get the path? any suggestions around would be appreciated...

When you say path you mean you want the path to print out in your HTML? Is that accurate? If so you generally need to constructe that path based on the path to the current component. So if you component is located at /content/mysite/en/about/mypage/jcr:content/parsys/image then the path to the image would generally be something like /content/mysite/en/about/mypage/jcr:content/parsys/image.img.jpg/1283829292873.jpg. The .img. selector triggers the servlet associated with the foundation parbase - /libs/foundation/components/parbase/img.GET.java. The reason you reference it this way is that there is no filesystem path to the image - it is stored in the repository not on the file system, and it requires a servlet or script to ge the binary from the repository and steam it.
Normally the way you'd construct this is to use the out of the box Image class - so look at /libs/foundation/components/image/image.jsp. Now this example assumes that your component where you loaded the image extends /libs/foundation/components/parbase. If it doesn't then you either have to change your sling:superResourceType to /libs/foundation/components/parbase or some other component that does exten /libs/foundation/components/parbase.

How to get the list of component?

 How to get the list of component through java API in Adobe CQ5?

There are probably more than a few ways, but here is a little component .jsp code that uses the jcr query api to pull out all the components and list them on a page. If I know CQ, there might be a way to ask for a list of components another way though, maybe through another API, or possibly a .json url, I might remember reading something about that, somewhere, lol, but this at least gets you the list in a somewhat simple way.
Code Example:
<%@include file="/apps/psul/components/global.jsp"%>
<%@ page import="javax.jcr.*,
 javax.jcr.query.*"
%>
<%
 // Login to create an anonymous session on the default workspace
 Session session = resourceResolver.adaptTo(Session.class);
 //Declare a query for all the components in the system
 String SQL = "select * from cq:Component";
//side note: if you want just the components in your site area, then make the query more like below...
// SQL = "select * from cq:Component where jcr:path like '/apps/yoursitename/%'";
 QueryManager qm = session.getWorkspace().getQueryManager();
 Query query = qm.createQuery(SQL, Query.SQL);
 QueryResult result = query.execute();
 NodeIterator nodes = result.getNodes();
 while (nodes.hasNext()) {
 Node node = (Node)nodes.next();
 %>
 <%=node.getName() %> (<%=node.getPath() %>)
<% } %>

How can I get the component LTC1060 in the multisim 10 library ?

How can I get the component LTC1060 in the multisim 10 library ?

ahnsei ,
This is a switched capacitor filter - with a variety of configurations for each mode of operation based on the switching frequency. To create a transistor level SPICE model would be unrealistic (which is probably why you haven't found one), so I would suggest looking at the datasheet and specifically, looking at each mode of operation and seeing if you can approximate the filter topology with an expression for the transfer function given in the datasheet (by calcuting based on the switching frequency).
Based on the expression you get, you can use the Multisim component "TRANSFER_FUNCTION_BLOCK" to plug in the correct transfer function and thus approximate the behavior of the filter in the circuit.
This transfer function can be found in the Master database -> Sources -> CONTROL_FUNCTION_BLOCKS. There was a previous discussion giving some additional details on how to setup the transfer function block:

How to get the room id & user id in our component

Hi Experts,

In that UI commend they mapped with the roomid and userid.
I need to know how to get the room id & user id in our component.

Hi Kathiresan,
you can get the Room ID and the User ID over the API.
Getting User ID within WebDynpro application:
IUser user = WDClientUser.getCurrentUser().getSAPUser();
String logonId = user.getUniqueId();
Getting User ID within custom Portal Component:
IPortalComponentRequest request = (IPortalComponentRequest) httpRequest;
IUser user = request.getUser();
String logonId = user.getUniqueId();
Getting Room Id of a user who belongs to this room:
IUser user = request.getUser();
IRooms roomsAPI = (IRooms) PortalRuntime.getRuntimeResources().getService(IRooms.PORTAL_SERVICE_ID);
IRoom[] myRooms = roomsAPI.getAllRoomsForUser(user);
String roomId = "";
for (int i=0; i<myRooms.length; i++) {
IRoom room = myRooms;
if (room.getName.equals('nameOfRoomToFind')) {

How to get the Dynamic UI component value from JSFF page to any managedbean

HI ,
We have list of bean objects in jSF page we are iterating the list of bean using the forEach loop and displaying the value into Input type text (UI component) value filed .
If we try to get the UI component value in Managed bean we are not getting the dynamic values .
The below piece of code used to retrieve the dynamic values from the JSF page doesn't have any form :
UIComponent component = null;
FacesContext facesContext = FacesContext.getCurrentInstance();
if (facesContext != null) {
UIComponent root = facesContext.getViewRoot();
component = findComponent(root, componentId);
then component type casting to the based on UI component which we trying to access and getting the value as " NULL " ..Please let me know how to get the dynamic values form the JSF ?
Please let me know if any other approach or any changes required on above ?
Thanks

Hi,
the root problem is this
<h:inputText id="it3" value="#{familyList.ctn}" />
<tr:commandButton text="Save" id="cb3"Note how each row writes to the same managed bean property, thus showing the same data. Instead your managed bean should expose a HashMap property that you then apply values to using a key/value pair. The key could be the ID of the field, which then you also should dynamically define e.g. cb<rowIndx>. The command button could then have a f:attribute assigned that has the row HahMap key as a value. This way you truly create value instances for the object
