Chained Dropdownlistbox - MVC

Hi All,,
I have 2 dropdownlist box in my view. i.e, COURSEGROUP and COURSE. When an entry in coursegroup listbox is selected , the COURSE listbox should be enabled and corresponding entries should be filled into the list items.
I have initially disabled the COURSE listbox.
I'm not using Model class for data binding.
My problem is:
When an OnSelect event occurs for COURSEGROUP list box, the control of program is going back to DO_REQUEST method and displays the same screen as earlier. The control is not entring the DO_HANDLE_EVENT method of controller..
I can also send the code if required.
Please help me out,,
Thanks in advance,,

Dropdownlistbox in iterator (mvc)

hi,
in my bsp i display a table via mvc iterator.
in the attributes of the iterator tab i have defined m_row_ref as type ref of the table displayed.
i have created as well a new field that i display in a dropdownlistbox.
this new field does not belong to the table displayed.
the question is:
do i have to add this new field to the table so that m_row_ref contains it?
or is there another way to know which value of the dropdownlistbox has been selected?.
Best regards.

Hi,
In the Attribute of the Iterator decalre a table which hold the key and the value.
Example
LT_SEQ_NO Instance Attribute Public Type CRMT_PRT_MAP
Populate the this table where ever you feel comfortable. I would declare constructor method of the iterator and populate it there.
go to method IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START
METHOD IF_HTMLB_TABLEVIEW_ITERATOR~RENDER_CELL_START .
DATA: lo_text TYPE REF TO cl_htmlb_textview,
 lo_ddlb TYPE REF TO cl_htmlb_dropdownlistbox.
FIELD-SYMBOLS: <dat> TYPE ANY.
row_ref = p_row_data_ref.
CASE p_column_key.
 WHEN 'SORT_NUM'.
 CREATE OBJECT lo_ddlb.
 GET REFERENCE OF lt_seq_no INTO lo_ddlb->table.
 lo_ddlb->id = p_cell_id.
 lo_ddlb->nameofkeycolumn = 'ENTRY_KEY'.
 lo_ddlb->nameofvaluecolumn = 'ENTRY_VALUE'.
 lo_ddlb->selection = get_column_value( p_column_key ).
 p_replacement_bee = lo_ddlb.
 WHEN OTHERS.
 CREATE OBJECT lo_text.
 lo_text->id = p_cell_id.
 lo_text->wrapping = 'FALSE'.
 lo_text->text = get_column_value( p_column_key ).
 lo_text->design = 'STANDARD'.
 p_replacement_bee = lo_text.
ENDCASE.
ENDMETHOD.
Modify the method as per your need.

Hello,
I have configured BizTalk Services Hybrid Connection between Standard Azure Website and SQL Server 2014 on premise.
Azure Management portal shows the status of Hybrid Connection as established.
However, the website throws an error when trying to open a connection

I tried various options with the connections sting (IP address instead of machine name, Trusted_Connection=False, Encrypt=False, etc. the result is the same

How to add a UIResponer object in the Responder Chain ?

Hello,
I'm quite new in iPhone developement and in Objective-C programming, and I am not very good (of course I'm French :)).
I'm sure my problem is simple, but I can't find a clear response in the doc and on the Web..
I have a custom view which implements the touchesBegan, touchesMoved, and touchesEnded methods in order to handle touch screen events. For a clear separation between View and Control (MVC pattern), I want to delegate these events to another class which inherits from the UIResponder class. How can I do that ?
I think I have to move the touchesBegan and touchesMoved methods into my new UIResponder class, but how can I indicate to the View that it must forward the events to my new UIResponder class ? In the doc (iPhone OS Programming Guide, Event Handling) it is said that we have to modify the Responder Chain, but I don't know how to do that... In the init method of my custom view, I just can't call the becomeFirstResponder method with my UIResponder class as a receiver because the canBecomeFirstResponder return NO.
Please help me ! I'm sorry to be such a noob.
Thank you !!

I think my problem is near to be solved : I have overriden the nextResponder method and returned my UIResponder object in my custom view . So I can handle the touch events in the responder. But the canBecomeFirstResponder still return NO in the init method of my custom view. Does someone know about that and can explain it to me ?
Thanks !

Chained Dropdown in Tableview?

Hi. I currently have 2 dropdowns in my Tableview. I need to make them chained. I don't know how to trigger an event within the tableview, so that if I select an item in one dropdown, the 2nd dropdown (only for that row) is updated with new values.
I had used a blog, and am able to create the chained behavior outside of tableview (on just a plain html page)...I just can't figure out how to trigger event within tableview. Any help is much appreciated.
Oh, and my application is NOT MVC.
Thanks in advance,
Lisa

Hi Lisa,
when you rendered a column as dropdown in table view it should also have an option to trigger an event when you select one entry in that. like OnSelect of dropdown 1 - trigger a event and then handle this event to refresh the droo down 2. I am not sure if you already tried this.

How to extend the sap.ui.core.mvc.Controller ?

We are in the process of building a web application that allows users to "plugin" their own views (pages). When they create there own views there are a number of activities that are common across all pages that occur in the onInit() and onExit() methods, additionally, we may provide additional utility functions that should be available to the controller.
Currently when creating a controller the standard is to use sap.ui.controller("some.name", { controller specific functionality } ); I would like to create a sap.ui.MyController("some.name", { controller specific functionality }); that contains the utility functions and extra functionality in the LifeCycle methods so that these are automatically available to anyone defining this type of controller.
I believe the documentation I need to reference is boilerplate code for typed Controller however I am unsure on how this can be used
I assume that I define the controller abc/xyz/MYController.js
jQuery.sap.declare({modName:"abc.xyz.MYController", type:"controller"}); // declaring a special type of module
abc.xyz.MYController = function () { // the constructor
    sap.ui.core.mvc.Controller.apply(this, arguments);
jQuery.sap.require("sap.ui.core.mvc.Controller"); // this is currently required, as the Controller is not loaded by default
abc.xyz.MYController.prototype = jQuery.sap.newObject(sap.ui.core.mvc.Controller.prototype); // chain the prototypes
/* end of boilerplate code for typed Controller */
abc.xyz.MYController.prototype.onInit = function() {
    // modify control tree - this is the regular lifecycle hook
    console.log("Inside my new controller.");
Then use it in app/pageController.controller.js ...
jQuery.sap.require("abc.xyz.MYController");
abc.xyz.MYController("app.pageController", { ..... });
When I try this I get the Error
Uncaught Error: failed to load 'app/pageController.controller.js' from /mywebapp/js/app/pageController.controller.js: Error: Controller type app.pageController is still undefined after trying to load it. sap-ui-core-all-dbg.js:20313requi
Any help with this would be appreciated.
Regards,
Trevor

Hi Trevor
may this code snippet will help.
    jQuery.sap.declare("example.MyController");
    jQuery.sap.require("sap.ui.core.mvc.Controller");
    "use strict";
    sap.ui.core.mvc.Controller.extend("example.MyController", {
        onInit: function () {

All I want is for the tree table renderers or editors to use the table created on the vieew part of this mvc
i will greatly appreciates your help

As a start point take sources of JTable (the component and datamodel) and rebuild them. I have made such component for my company product. To write it I spend 5 days and about two weeks for debugging. This code cannot be very simple. As it should be fully mutable. For example, each line should have bkcolor, fgcolor, font, etc. Each sell has bkcolor, fgcolor, font, insets, border, alighnment, visibility, etc. Each node has its cell, indent and array of data cells. To support fast scrolling the painting should be buffered. My components also supports text line wrapping. The tree component consists of three parts: the header, the left part and the matrix of data. This component can be printed (this is a secial code for paging and scaling).

Hey Jan,
Oracle's E-Business suite is moving to a JSF solution. This is really for three main reasons (abbreviated version):
1) JSF is much more focused on the 'view' components. The component model has a clean separation of the component definition from its rendering. This, among many other things, allows us to provide a consistent development environment and APIs for developers building apps for browsers, mobile devices, telnet devices, etc.
2) JSF has a better defined lifecycle. The JSF lifecycle maps much closer to the phases that enterprise applications need when processing data from a web application. We are able to easily extend this to add things not currently in the spec, like portlets, wireless, etc., as well as more easily plug new components into the framework.
3) Once you remove the JSP tags & FormBean from Struts, all you are left with is the navigation. There is nothing special in the Struts navigation that would cause us to try to make the two technologies work together. In fact, the Faces navigation will not be robust enough in its current form to support the declarative navigation requirements for Oracle apps. We plan to extend the JSF navigation and then work to submit that back into the standards.
Hope this helps,
Ted Farrell

MVC Drop Down List Event Handler

Hello,
I am trying to create a bsp page using MVC design pattern. I have 3 drop down list fields which are dependent on each other. Example: When you select a value in list 1, drop down list 2 becomes enabled for selection with values based on list 1. At this point of time list 3 should be disabled. Once you select value from 2, list 3 becomes enabled with values based on list 2 selection.
I have seen a webblog on this topic from Raja but it was designed for bsp page flow design. Could you please guide how do I achieve this in MVC?
Please help.
This is what I did:
I have 1 controller and 1 view.
In my view:
=========================================================
<htmlb:gridLayoutCell columnIndex="2" rowIndex="1">
<htmlb:dropdownListBox id = "DDLB_PLANT"
 tooltip = "Plant"
 table = "<%= v_plants %>"
 onSelect = "DDLB_PLANTEvent"
 selection = "<%= v_plantsel %>">
 nameOfKeyColumn = "WERKS"
 nameOfValueColumn= "DESC_TEXT">
</htmlb:dropdownListBox>
</htmlb:gridLayoutCell>
<htmlb:gridLayoutCell columnIndex="2" rowIndex="2">
<htmlb:dropdownListBox id = "DDLB_SHIFT"
 tooltip = "Shift"
 table = "<%= v_shifts %>"
 onSelect = "DDLB_SHIFTEvent"
 selection = "<%= v_shiftsel %>">
 nameOfKeyColumn = "SHIFT"
 nameOfValueColumn= "SDESC">
</htmlb:dropdownListBox>
</htmlb:gridLayoutCell>
where v_plants and v_shifts are page attributes (table) that is being populated in DO_REQUEST method of controller. v_plantsel and v_shiftsel are type string (page attribute).
In DO_HANDLE_EVENT (controller)
DATA: event_id TYPE REF TO if_htmlb_data,
 ddlb_event TYPE REF TO cl_htmlb_event_selection,
 data TYPE REF TO cl_htmlb_dropdownlistbox.
event_id = cl_htmlb_manager=>get_event( request ).
IF event_id IS NOT INITIAL.
 ddlb_event ?= event_id.
 IF ddlb_event->id EQ 'DDLB_PLANTEvent'.
 c_plantsel = ddlb_event->selection.
 ELSEIF ddlb_event->id EQ 'DDLB_SHIFTEvent'.
 c_shiftsel = ddlb_event->selection.
 CLEAR data.
 data ?= cl_htmlb_manager=>get_data( request = runtime->server->request
name = 'dropdownListBox'
id = 'DDLB_PLANTEvent'
IF data IS NOT INITIAL.
c_plantsel = data->selection.
ENDIF.
ENDIF.
ENDIF.
=========================================================

Mvc - connection pool - jstl - oh my!

I am trying to understand how to use the mvc model to break my existing jsp's up. I finally got my connection pool working yesterday(yay!) so now I want to get everything organized into servlets. My understanding of servlets sucks - and I have not written one yet. Researching it on the net hasnt helped much - a bit overwhelming..
Please tell me if my logic is on track or not - keeping in mind the mvc model - keeping in mind I dont know how to write a servlet : )
DATABASE package;
public static dbpool getConnection() {
// write JNDI information
public static void dbpoolClose(Connection connDB) {
// close connection
}Then in a servlet I would try to write something like this...
MyBean {
// call the connection method
- do crud operations
- use getters and setters
- close statements that I have open
// call the close connection method
}Then in my JSP( I have JSTL working YAY!!) I wil call the bean/getters/setters and use JSTL to manipulate and present the data? Is this close to being in the MVC model?
I havent found an example using the mvc using a connection pool, database operations and a jsp - that I have been able to understand.. so If I am waay off.. sorry.

Basically, use the servlet to tell other classes what to do (these can be other servlets or whatever).
Those classes prepare the data you want to have the JSPs show and process the data returned from the JSPs.
The JSP does nothing except display data presented to it by the servlet (and may have URLs or forms to provide input to servlets.
At its simplest, there's no controller at all (so no C). A JSP calls a servlet which processes the data sent to it and prepares new data for another (or the same) JSP to which it forwards the request when done.
That data can be stored in the Http session or (sometimes) better in the request.
More usually, a controller will receive all requests from and determine to what servlet to send them.
The servlet then either determines on its own to which JSP to send the results or gives those results back to the controller which will do that for them and forward to the proper JSP.
If needed you can thus chain requests so that a request goes to a servlet, from there to another servlet and then to a JSP (for example), each time via the controller.
This can be handy to break up complex processing in small steps where those small steps could also occur separate.

Dropdownlistbox

Hello,
we have 2 dropdownlistboxes in a MVC based BSP Applikation. Depending the selection of the first dropdownlistbox, we want to set the attribute "disabled" of the second dropdownlistbox, so the user cannot select anymore from the second dropdownlistbox.
If we switch back the selection of the first dropdownlistbox the user should be able again to select values from the second one.
it works fine the first time we call the page, but not when we change the selection.
any help is greatly appreciated.
thx and regards from Michael

Hi Mike,
glad to help.
The issue with binding to the model is that the user interaction forces a HTTP request back to the server whereas the client-side scripting technique does not.
IMHO the server callback diminishes the user experience.
Cheers

I have a MBPro mid 2013 with 1 Thunderbolt port. Just bought a Mac monitor and want to daisy chain a PC monitor to it. Use a Mini DVI to VGA adapter from MBP to PC monitor. How do I daisy chain the 2 monitors?

I have a MBPro mid 2013 with 1 Thunderbolt port. Just bought a Mac monitor and want to daisy chain a PC monitor to it. Use a Mini DVI to VGA adapter from MBP to PC monitor. How do I daisy chain the 2 monitors?

Hall Palm Desert,
if your Mac monitor has Thunderbolt ports, and the PC monitor is on the end of the daisy chain, then you might be able to do it by connecting your PC monitor’s VGA cable to a Mini DisplayPort-to-VGA adapter (e.g. Apple, NewerTech), connecting that cable’s Mini DisplayPort end to one of the Mac monitor’s Thunderbolt ports, and then connecting a Thunderbolt cable between the other port on the Mac monitor and your MacBook Pro.

Questions on Multiprovider and Process Chain

Hai All,
          I have two questions. One on Multiprovider and the other on Process chain.
1. Multiprovider:
          For example, I have 2 ODSs. ODS1 has Objects ORDER NUMBER, COUNTRY and PRODUCT, ODS2 has objects ORDER NUMBER, DELIVERY STATUS, CREATION DATE.
Now if I make a multiprovider on ODS1 and ODS2, then as ORDER NUMBER is common in both the ODSs, can I make a report like this:
ORDER NUMBER - DELIVERY STATUS, CREATION DATE?
         I have a problem here bacuase its not getting those details from the other ODS even though the ORDER NUMBER(value) is same. Am I making nay mistake or is it a system problem.
I beleive thats how a Multiprovider works.
2. Process chain:
                I have an END connector in my process chain that connects 3 processes and lets the following task start only after the success of all the above 3 processes.
The system is displaying the END connector seperately under each process. But the name and everything else is same. Is this a setting somewhere in the process chain?
Thank you.

Hi,
1. Those fields are in ODS2, you don't need to make a multiprovider.
2. You mean an AND connector. Maybe you need to refresh the screen. if this doesn't work, delete the three and connectors and insert a new one.
Hope this helps.
Regards,
Diego

Hello again!
Anyone that can help me figure out how to implement this in an MVC layout, I feel stuck.
I post a little program that open and display an image file so that you better can understand what I whant to do.
ShowImage
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.io.File;
import javax.swing.filechooser.*;
public class ShowImage extends JFrame{
     //Variables
     JFileChooser fc = new JFileChooser();
     PicturePanel pp = null;
     ShowImage () {
          super("Show"); //Title
          //Create the GUI
          JPanel top = new JPanel();
          add(top, BorderLayout.NORTH);
          JButton openBtn = new JButton("Open");
          top.add(openBtn);
          openBtn.addActionListener(new Listner());
          //Settings for the GUI
          setDefaultCloseOperation(EXIT_ON_CLOSE);
          pack();
          setVisible(true);
     class Listner implements ActionListener {
          public void actionPerformed(ActionEvent ave) {
               int answer = fc.showOpenDialog(ShowImage.this);
               if (answer == JFileChooser.APPROVE_OPTION){
                    File f = fc.getSelectedFile();
                    //Check
                    System.out.println(f);
                    System.out.println(pp);
                    if (pp != null)
                         remove(pp); //Clean so that we can open another image
                    //Check
                    System.out.println(pp);
                    //Set the PicturePanel
                    pp = new PicturePanel(f.getAbsolutePath());
                    //Check
                    System.out.println(pp);
                    //Add PicturePanel to frame
                    add(pp, BorderLayout.CENTER);
                    validate();
                    pack();
                    repaint();
     //Main
     public static void main(String[] args) {
          new ShowImage();
}PicturePanel
//Import Java library
import javax.swing.*;
import java.awt.*;
public class PicturePanel extends JPanel {
     //Variables
     private ImageIcon picture;
     //Method to get information of the selected file
     PicturePanel (String fileName) {
          picture = new ImageIcon (fileName); //Get the filename
          int w = picture.getIconWidth(); //Get the image with
          int h = picture.getIconHeight(); //Get the image height
          //Set preferable size for the image (Use the properties for the selected image)
          setPreferredSize(new Dimension(w, h));
          setMinimumSize(new Dimension(w, h));
          setMaximumSize(new Dimension(w, h));
     //Method to draw the selected image
     protected void paintComponent(Graphics g) {
          super.paintComponent(g); //We invoke super in order to: Paint the background, do custom painting.
          g.drawImage(picture.getImage(), 0, 0, this); //Draw the image at its natural state
}//The endEdited by: onslow77 on Dec 16, 2009 7:30 PM
