Enhance standard class with event handler method

In trying to enhance a standard class with a new event handler class, I find that the ECC 6.0 EHP4 system does not appear to recognise the fact the method is an event handler method. The specific example is a new method to handle the event CL_GUI_ALV_GRID->USER_COMMAND.
I notice that the flag called Active has not been ticked - see image below. Perhaps this is the reason why the event handler is not being triggered.
Note that there is an event handler for the same event in the standard class which obviously is executed as expected. Any ideas on limitations in the system or I am missing a step?
Thanks
John

Thank you for your replies.
There is a bug in the ALV handler of a standard SAP class (when executed in ITS WebGUI) and I was hoping to create a custom event handler as an Enhancement to execute some custom code to sort of "handle the bug".
I agree - ideally it should be done in a Z class but that will not give me access to the object methods and attributes of the enhanced class.
Cheers,
John

View not copied or enhanced with wizard Error while creating Event Handler method in Z Component

Hello Friends,
In one Z Component (Custom Component), in one of the views, while creating event handler, it gave me error message that view not copied or enhanced with wizard.
I am aware that in Standard Component, if we want to create the event handler method then we need to first Enhance the Component and then we need to enhance the view.
But, in the Z Component (Custom Component), how to create event handler method in one of the views as while creating event handler method i am getting view not copied or enhanced with wizard error.

Hi,
Add a method in views impl class with naming convention eh_on__* with htmt and html_ex parameters. I dont have have the system right now. Please check any existing event import export parameters.
Check out do handle event method in the same class.
Redefine that method. Call that event method in this handle method. See existing code for reference.
Attach that event to the button on click event in .htm page.

Enhanced SAP class with new methods - Not showing these from standard task

Dear Gurus,
I have enhanced SAP standard class with new methods. After I have activated my new methods and would like to create a workflow task using these new methods. when I create a task and input object category as "ABAP Class" and object type is SAP enhanced class. When I try to drop down for methods SAP is not showing my new methods. I do not know why. Am I missing any? Any help would be appreciated.
Note: Remember I am trying to use SAP ABAP class custom methods.
Thanks,

JDEV 10.1.3: Issue with Inherited public event handler methods in beans

I have a bean validator method which it inherits from another base class.
I am able to pick this method using the property inspector and it works fine.
But in the jspx source view, i see a red wiggly line under the expression. Is this a bug or some bizzare way of enforcing some best practice (if using inherited event handler methods in beans is NOT a best practice)?
The same is true for value change listeners.

I started from scratch and the problem remains. Only one commandButton can fire an event which sets a variable that controls a af:switcher. The effect is similar to what the "blocking" attribute does but it is set to false on my components. Any ideas, time has already run out.

Repetitive call of event handler method

hi,
       i ve some 8 screens with alv grid controls on each...i'm using
same subroutine for event handling for all the controls...the problem
is whenever i navigate from 1 to the other and return back to the same,
after data change, the event handler method is getting called as many times
i ve navigated....for toolbar actions i used befor user command event and
overcame but for data changed i got struck... Plz tel me the reason and how can we avoid.....
Thanks

Problem with event handling

Hello all,
I have a problem with event handling. I have two buttons in my GUI application with the same name.They are instance variables of two different objects of the same class and are put together in the one GUI.And their actionlisteners are registered with the same GUI. How can I differentiate between these two buttons?
To be more eloborate here is a basic definition of my classes
class SystemPanel{
         SystemPanel(FTP ftp){ app = ftp};
         FTP app;
         private JButton b = new JButton("ChgDir");
        b.addActionListener(app);
class FTP extends JFrame implements ActionListener{
           SystemPanel rem = new SystemPanel(this);
           SystemPanel loc = new SystemPanel(this);
           FTP(){
                   add(rem);
                   add(loc);
                   pack();
                   show();
       void actionPerformed(ActionEvent evt){
        /*HOW WILL I BE ABLE TO KNOW WHICH BUTTON WAS PRESSED AS THEY
           BOTH HAVE SAME ID AND getSouce() ?
           In this case..it if was from rem or loc ?
} It would be really helpful if anyone could help me in this regard..
Thanks
Hari Vigensh

Hi levi,
Thankx..
I solved the problem ..using same concept but in a different way..
One thing i wanted to make clear is that the two buttons are in the SAME CLASS and i am forming 2 different objects of the SAME class and then putting them in a GUI.THERE IS NO b and C. there is just two instances of b which belong to the SAME CLASS..
So the code
private JButton b = new JButton("ChgDir");
b.setActionCommand ("1");
wont work as both the instances would have the label "ChgDir" and have setActionCommand set to 1!!!!
Actually I have an array of buttons..So I solved the prob by writting a function caled setActionCmdRemote that would just set the action commands of one object of the class differently ..here is the code
public void setActionCommandsRemote()
     for(int i = 0 ; i <cmdButtons.length ; i++)
     cmdButtons.setActionCommand((cmdButtons[i].getText())+"Rem");
This just adds "rem" to the existing Actioncommand and i check it as folows in my actionperformed method
     if(button.getActionCommand().equals("DeleteRem") )
                    deleteFileRemote();
      else if(button.getActionCommand().equals("Delete") )
                 deleteFileLocal();Anyway thanx a milion for your help..this was my first posting and I was glad to get a prompt reply!!!

How to Call Event Handler Method in Another view

Hi Experts,
                   Can anybody tell me how to call Event handler Method which is declared in View A ,it Should be Called in
view B,Thanks in Advance.
Thanks & Regards
Santhosh

hi,
1)    You can make the method EH_ONSELECT as public and static and call this method in viewGS_CM/ADDDOC using syntax
    impl class name of view GS_CM/DOCTREE=>EH_ONSELECT "method name.
             or
2)The view GS_CM/ADDDOC which contains EH_ONSELECT method has been already enhanced, so I can't execute such kind of operation one more time.
                     or
3)If both views or viewarea containing that view are under same window , then you can get the instance ofGS_CM/DOCTREE from view GS_CM/ADDDOC through the main window controller.
lr_window = me->view_manager->get_window_controller( ).
    lv_viewname = 'GS_CM/DOCTREE '.
lr_viewctrl ?= lr_window ->get_subcontroller_by_viewname( lv_viewname ).
Now you can access the method of view GS_CM/DOCTREE .
Let me know in case you face any issues.

The ALV object Grid methods allow the same functionality as ALV grid report function modules but are displayed within
a screen (dialog program). SAP has provided a suit of programs which demonstrate how to For examples see standard SAP
programs as detailed below:
BCALV_EDIT_01 This report illustrates the simplest case of using an editable/noneditable ALV Grid Control.
BCALV_EDIT_02 This report illustrates how to set chosen cells of an ALV Grid Control editable.
BCALV_EDIT_03 In this example the user may change values of fields SEATSOCC (occupied seats) and/or PLANETYPE.
The report checks the input value(s) semantically and provides protocol messages in case of error
BCALV_EDIT_04 This report illustrates how to add and remove lines to a table using the ALV Grid Control and how to
implement the saving of the new data.
BCALV_EDIT_05 This example shows how to use checkboxes within an ALV Grid Control. You learn:
     (1) how to define a column for editable checkboxes for an attribute of your list
     (2) how to evaluate the checked checkboxes
     (3) how to switch between editable and non-editable checkboxes
BCALV_EDIT_06 This example shows how to define a dropdown listbox for all cells of one column in an editable ALV
Grid Control.
BCALV_EDIT_07 This example shows how to define dropdown listboxes for particular cells of your output table.
BCALV_EDIT_08 This report implements an ALV Grid Control with an application specific F4 help. The following aspects
are dealt with:
     (1) how to replace the standard f4 help
     (2) how to pass the selected value to the ALV Grid Control
     (3) how to build an f4 help, whose value range depend on a value of another cell.

Event handler method

Hi all,
I want to know the significance of creating event handler method in Class builder.
and how it can be used at the time of event trigger.( Is it called automatically or programmer need to call it explicitly in the program.)
Thanks,
Sushant singh

Hi Sushant,
1. In ABAP Objects, triggering and handling an event means that certain methods act as triggers and trigger events, to which other methods - the handlers - react. This means that the handler methods are executed when the event occurs.
2.To trigger an event, a class must
Declare the event in its declaration part
Trigger the event in one of its methods
3.You declare events in the declaration part of a class or in an interface. To declare instance events, use the following statement:
EVENTS evt EXPORTING... VALUE(e1 e2 ...) TYPE type [OPTIONAL]..
4. An instance event in a class can be triggered by any instance method in the class. Static events can be triggered by any method. However, static methods can only trigger static events. To trigger an event in a method, use the following statement:
RAISE EVENT evt EXPORTING e1 = f1 e2 = f2 ...
5. Events are handled using special methods. To handle an event, a method must
be defined as an event handler method for that event
be registered at runtime for the event.
Declaring Event Handler Methods
Any class can contain event handler methods for events from other classes. You can, of course, also define event handler methods in the same class as the event itself. To declare an event handler method, use the following statement:
METHODS meth FOR EVENT evt OF cif IMPORTING e1 e2 ...
6. Registering Event Handler Methods
To allow an event handler method to react to an event, you must determine at runtime the trigger to which it is to react. You can do this with the following statement:
SET HANDLER h1 h2 ... [FOR]...
It links a list of handler methods with corresponding trigger methods. There are four different types of event.
7. Timing of Event Handling
After the RAISE EVENTstatement, all registered handler methods are executed before the next statement is processed (synchronous event handling). If a handler method itself triggers events, its handler methods are executed before the original handler method continues. To avoid the possibility of endless recursion, events may currently only be nested 64 deep.
Handler methods are executed in the order in which they were registered. Since event handlers are registered dynamically, you should not assume that they will be processed in a particular order. Instead, you should program as though all event handlers will be executed simultaneously.
Reward if useful.

Accessing exception information in an event handler method

Hi,
I am trying to handle an event thrown by a fatal exception. I am able to capture the event in this event handler method. However, I need to access the PREVIOUS of the exception in this event handler method and am not sure how to do it.
Can some one please help with this?
Thanks
Saravanan.

Hi,
Look at this code end check if your program works in the similar way.
Here, i'm changing an atribute from one class from other class.
If it doesn't works and you can't change an atribute directelly, i really don't know other way to do this.

Handling exceptions for a event handler method.

Hi Mates,
I have two custom container in which i am displaying an alv grid usind objects. when a double click event is performed in one of the alv the other alv should be displayed. I now have to handle exceptions of the class CX_SY_DYN_CALL_ILLEGAL_TYPE. This is raised for an invalid parameter type when calling a method dynamically. I cannot use the keyword "RAISING" in the definition of the event handler method. i checked with the syntax of the method definition in abap dictionary, there were no addition "RAISING" for an event handler method. please provide me with the solution (a sample code would do.)

Hello,
May be you should read about the TRY ... CATCH block which is used for handling exceptions.
Basic construct of your code should look like this:
TRY.
" Your Dynamic Method call
CATCH CX_SY_DYN_CALL_ILLEGAL_TYPE.
ENDTRY.
If you want to get the error message text:
DATA:
lcx_excp TYPE REF TO CX_SY_DYN_CALL_ILLEGAL_TYPE,
v_err_msg TYPE string.
TRY.
" Your Dynamic Method call
CATCH CX_SY_DYN_CALL_ILLEGAL_TYPE INTO lcx_excp.
v_err_msg = lcx_excp->get_text( ).
ENDTRY.

Is there any way to send value to my attribute through event handler method

While I give value to the img array it does not print while I call object for this class. Is there any way that I could give value for img attribute
// Attribute
public var img:Array;
// Constructor
public function ReadXML(myfile:String) {
            img=new Array();
            xmlFile=myfile;
            var loader:URLLoader=new URLLoader;
            var url:URLRequest=new URLRequest(xmlFile);
          loader.addEventListener(Event.COMPLETE,onXMLLoad);
            loader.load(url);
// Event handling Method
        function onXMLLoad(event:Event):Array {
            var xml:XML=new XML(event.target.data);
            //trace(xml);
            //trace("Number of Contacts : " + xml..person.length());
            //trace("First contact’s favorite food : " + xml.contacts.person[0].@favoriteFood);
            img["height"]=100;
            img["width"]=200;
            return img;

what are you trying to do?
if img has anything to do with an image, explain.
if img is supposed to be an associate array, use:
var img:Object;
img=new Object();
etc

Populating database tables in event handler method - error

Friends,
I am trying to insert values into ztable in an event handler method in a WDA application.
This is the code. ZDATA1 is a ztable with two fields: MANDT and ZKTOKD of data element char01.
types: begin of zs,
zktokd type char01,
end of zs.
data: zitab type table of zs,
zstruct like line of zitab.
zstruct-zktokd = 's'.
append zstruct to zitab.
INSERT zdata1 FROM TABLE zitab.
I am getting the error: "The Work area "ZITAB" is not long enough...
Please let me know what is missing.
Thanks and Regards.

Hi,
The error is here
types: begin of zs,
zktokd type char01,
end of zs.
data: zitab type table of zs ,
zstruct like line of zitab.
"passed the Internal table name which is wrong
Correct one
data:
zitab type table of zs,
zstruct like line of ZS. " Here we have to give the type you have declared above.
" Zstruct acts like a workarea.
Regards

Migration from Serial polling to Serial queue with event handler

Hi, I am trying to migrate from classical serial polling communications to serial queue with "event handler" for the buttons pressed by the user. I have placed four while loops, one for the event handler, a second one for serial reading, a third one for serial writing (depending on what button was pressed) and the last one for processing what was read from the serial reading while loop, via a queue.
My attached device reads the signals from 8 sensor ( 4 temperature and another 4 temperature plus humidity in the same sensor ) and send them via serial to Lavbiew.
First of all, only once just after running the LV program, I must turn on my attached device with an ON command plus a carriage return after that the device will respond with the number of sensors plugged to it, disabling the corresponding buttons in the front panel. Then labview must wait until I pressed Acquire Button (event handler) and send a CF command plus what sensors to acquire plus a carriage return, then the device will respond continuously to labview with the sensor readings until I press the stop button (event handler), there is also another button to exit the program, also with event handler.
I am having problems using the event handler and the queues because I am new using these structures, I have looked at the LV examples but there is nothing concrete on using serial with event handler and queue.
Take a look at my VI and you will soon notice what kind of problems I am having, any suggestions will welcome.
Thank's in advance.
Regards.

Hi Luisete,
Maybe the problem arise because you are En- and DeQueue in parallel. You do a lot of things in parallel, that is nice if you are sure that one loop doesn't have to wait for another loop. Make sure you don't dequeue before enqueue.
Hope this helps
I never knew that the standard error cluster output could be wired directly to the loop control of a while loop.
First time I see this

Need Help with Event Handler Code - Doesnt come up in Event Handler Manager

Hello there,
Below is the code snippet that I am using to create a event handler:
package com.oracle.events;
import com.thortech.util.logging.Logger;
import com.thortech.xl.client.events.tcBaseEvent;
import com.thortech.xl.dataobj.tcDataObj;
import com.thortech.xl.util.logging.LoggerModules;
public class tcCheckOvrallProvStatusUDFs extends tcBaseEvent
     private static Logger logger = Logger.getLogger(LoggerModules.XL_JAVA_CLIENT);
     public tcCheckOvrallProvStatusUDFs()
          setEventName("Generating tcCheckOvrallProvStatusUDFs");
* @Override
* @throws Exception
     protected void implementation() throws Exception {
          tcDataObj data = getDataObject();
          String OIDProvStatus = data.getString("usr_udf_oidusrprovstatus");
String EBSProvStatus = data.getString("usr_udf_ebstcausrprovstatus");
          if (OIDProvStatus.equals("Provisioned") && EBSProvStatus.equals("Provisioned")) {
               setOverAllProvStatus(data);
     * @param data
     * @throws Exception
     private void setOverAllProvStatus(tcDataObj data) throws Exception
          data.setString("usr_udf_ovrrscprovstatus", "Provisioned");
Its a simple code that I am using to populate value of a UDF field depending on the value of other 2 fields. I want to trigger it on Post-Insert and Post-Update events.
But even if I restart the OIM server after placing the successfully compiled file (0 errors, 0 warnings) into the EventHandlers folder of OIM_HOME; it doesnt show up in the Design Console -> Development Tools -> Business Rule Definition -> Event Handler Manager. :( In order to create a event handler i need that file to show up in the lookup of event handlers/adapters. This JAR file doesnt come up over there.
Is there anything missing within the code ?
What else needs to be specified?
Please provide some guidance.
Thanks,
