How to create dynamic event handler methods?

Hello!
Is it possible to create dynamic event handler methods in the views of WDC and then subscribe to an event of another WD component completely dynamically.
Many thanks,
Smitha.

By first realising AJAX is not Java but JavaScript and then reading a tutorial on JavaScript DOM manipulation and then by reading a tutorial on AJAX and then by applying your knowledge and then in the end by integrating it in your JSP.

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.

How do I create an Event Handler for an Execute SQL Task in SSIS if its result set is empty

So the precedence on my entire package executing is based on my first SELECT of my Table and an updatable column. If that SELECT results in an empty result set, how do I create an Event Handler to handle an empty result set?
A Newbie to SSIS.
I appreciate your review and am hopeful for a reply.
PSULionRP

Depends upon what you want to do in the eventhandler. this is what you can do
Store the result set from the Select to a user variable.
Pass this user variable to a Script task.
In the Script task do whatever you want to do including failing the package this can be done by failing the script task, which in turns fails the package. something like
Dts.TaskResult = Dts.Results.Failure

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.

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.

Repetitive call of event handler method

hi,

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.....

Dynamic Event Handler

I'm looking for a dynamic event handler subscribe/unsubscribe process, something like this:
foreach (Control ctrl in form.Controls)
if (ctrl.GetType() == typeof(TextBox)
TextBox tb = (TextBox)ctrl;
if (tb.Name == "tbLocationName")
==>tb.TextChanged -= new EventHandler(tb_TextChanged);
Is this structure possible? Currently, I have to iterate a literal list of controls and I'm looking for something a little more compact.
timSF

You could create a MethodExtension for that :). Method extensions need to be declared in a static context, so to keep things organized you can create a seperate static class for all your MethodExtensions (or group them by category).
Here is an example:
using System;
using System.Collections.Generic;
using System.Windows.Forms;
namespace ExtensionExample
public partial class Form1 : Form
private List<TextBox> _unsubscribeList = new List<TextBox>();
public Form1()
InitializeComponent();
textBox1.TextChanged += Textbox_TextChanged; //Subscribe to event
textBox2.TextChanged += Textbox_TextChanged; //Subscribe to event
textBox3.TextChanged += Textbox_TextChanged; //Subscribe to event
textBox4.TextChanged += Textbox_TextChanged; //Subscribe to event
textBox5.TextChanged += Textbox_TextChanged; //Subscribe to event
FooBar();
public void FooBar()
_unsubscribeList.Add(textBox1); //Add Textbox1
_unsubscribeList.Add(textBox5); //Add Textbox5
//'this' == our Form => Method Extension
this.TextBoxes_Unsubscribe(Textbox_TextChanged, _unsubscribeList); //Call Method Extension
private void Textbox_TextChanged(object sender, EventArgs e)
var txtbx = sender as TextBox;
Console.WriteLine("Text Changed: " + txtbx.Name);

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

How to create the event in the report for jobs scheduling.

Hi Experts,
i have a requirement like as follows:
The following triggers for Batch Jobs in the SCM system will be created.i.
Background Processing Event = u201CAPO Background Processing Eventu201D. After sending the Event, write a Log Report line u201CEvent u201CAPO Background Processing Eventu201D sentu201D.
Could you please suggest me how we create the Event or which transaction ?
Please give me a steps for creating events so that based on these events we use
CALL METHOD cl_batch_event=>raise
    EXPORTING
      i_eventid                      = p_bpeve
      i_server                       = p_server
      i_ignore_incorrect_server      = p_ignore
    EXCEPTIONS
      excpt_raise_failed             = 1
      excpt_server_accepts_no_events = 2
      excpt_raise_forbidden          = 3
      excpt_unknown_event            = 4
      excpt_no_authority             = 5
      OTHERS                         = 6.
Right now i received message "APO Background Processing Event" is doesn't exists.
Thanks in Advance.
Puneet.

Hi Puneet,
Goto transaction SM62 and in there to BckProcEvents tab. There you can create the events.
You just need to specify the name and Description of an event.
Hope this serves your purpose.
Thanks

How to create dynamic context based on a structure defined in the program?

Hi Experts,
         I need to create a dynamic context based on a structure wa_struc which i have define programatically.
When I pass wa_struc to structure_name parameter of create_nodeinfo_from_struc, i get a runtime error:
"Parameter STRUCTURE_NAME contains an invalid value wa_struc."
How to create dynamic context based on a structure defined in the program?
I have written the code like this:
TYPES: BEGIN OF t_type,
            v_carrid TYPE sflight-carrid,
            v_connid TYPE sflight-connid,
         END OF t_type.
Data: i_struc type table of t_type,
         wa_struc type t_type.
data: dyn_node   type ref to if_wd_context_node.
data: rootnode_info   type ref to if_wd_context_node_info.
rootnode_info = wd_context->get_node_info( ).
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
parent_info = rootnode_info
node_name = 'dynflight'
structure_name = 'wa_struc'
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( name = 'dynflight' ).
dyn_node->bind_table( i_struc ).
Thanks

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :
The following error text was processed in the system PET : Line types of an internal table and a work area not compatible.
The error occurred on the application server FMSAP995_PET_02 and in the work process 0 .
The termination type was: RABAX_STATE

How to create dynamic variable in Java?

Hi,
I want to create dynamic varible , using ArrayList or Vector. The number of array i dont knwo, so how to create dynamic ArrayList or Vector.
for example:
ArrayList1,ArrayList2,ArrayList3.....n
or
Vector1,Vector2,Vector3 .....n, the n value i will get at run time, so how to create the dynamic ArrayList or Vector or i can use any other Object in java,
Pls provide your input.
Sridhar

1. I have a HashMap with dataok ... fair enough.
2. depending on its size, i need to create variable
to store them.uhm ... why? If you have a variable number of elements in the map then you'd need to generate a variable number of variables (a number, that is not know at compile time, as it seems). Now if you could somehow create those variables, how would you access them? You'd have to generate the code handling them as well ...
Tell us what kind of data you've got and what you want to do with it. There's certainly a better solution to your problem.

Button's Event Handler Method not getting triggered

To add a button I have written the following code:
clear ls_button.
    l_import = 'Mass Upload'.
    l_enabled = 'X'.
    clear ls_button.
    ls_button-on_click = 'UPLOAD'. "IMPORT FILE
    ls_button-text     = l_import.
    ls_button-enabled = l_enabled.
    INSERT ls_button INTO rt_buttons INDEX 5.
Created a new Event Handler method for it and wrote the following code:
gr_file_popup = comp_controller->window_manager->create_popup(
    iv_interface_view_name = 'ZSRQM_INCID_H/FileUploadwindow'
    iv_usage_name = 'ZCufileupload'
    iv_title = l_title ).
gr_file_popup->set_on_close_event( iv_view = me iv_event_name = 'upload' ).
gr_file_popup->open( ).
When i run in th component in debug mode,my event is not getting triggered.
Please suggest.
Regards
Najam

Try the following code in first part...
clear ls_button.
    l_import = 'Mass Upload'.
    clear ls_button.
    ls_button-on_click = 'UPLOAD'. "IMPORT FILE
    ls_button-text     = l_import.
    ls_button-page_id = me->component_id.
    ls_button-enabled = abap_true.
    INSERT ls_button INTO rt_buttons INDEX 5.
