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

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.

Error in event handler method in window

Hi,
I have created configuration in SEFVISU, to receive the workitem i have created a parameter in event handler method in window
but it is throwing dump The ASSERT condition was violated, if i remove that parameter means application executing properly but i am not able to pass the unique, values please guide me.
Regards,
Srini.

Hello Srini,
are you talking about the default event handler method of the window? if so then you need to ensure that the parameter name defined in the event and passed in name are same. And also its better to go for the parameter type as STRING.
other option would be instead of defining the static parameters in the event handler method, you can get the parameters from the WDEVENT itself by accessing WDEVENT->PARAMETERS table.
hope this helps.

Using page attribute in event handler method of controller

Hi all,
I have created a page attribute GT_TABLE. I need to use this table in one of the event handler methods of the controller of the same page. I tried to use the GET_ATTRIBUTE method but it always returns an empty table.
Can someone please guide me in this respect.
Thanking you in advance,
Regards,
Sumit.

Hi Sumit,
The page attribute you mention (GT_TABLE) it's an internal table, isn't it? So far I know, the value of internal table will gone when BSP finish to load in server. If you want to keep the data in internal table, you need to load the internal table into Session (in one of page event in BSP).

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.

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

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 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.

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.

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?

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.

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

Event handler method definitions - whats the difference

hi folks,
i'm a newbie and have just started trying to get my head
around flash 8 actionscript.
is anyone able to advise me what is the
distinction/difference/subtlety between defining an event handler
method ON a keyframe as compared to defining an event handler
method WITHIN a keyframe.
evidently this is a keypoint to understand so if i don't get
this clear i expect it'll cause me grief later.
thanx for your response.
regards,
avonova

I wouldn't say ON a keyframe, that sounds like on a frame. I
believe you mean the difference between on(clip event) which is
placed on an instance of a movieclip or myClip.onClipEvent which is
code placed on a timeline/frame.
Thanks aniebel for that link. David Stiller is a genius and
really hit the point.
For me code consolidation is certainly the biggest reason for
it as well. But from that you start to see ways to put your code
together that are just better and lead naturally into OOP style and
concepts.
avonova – it is totally worth learning how to do it
this way. In AS3 you will no longer be able to use any of the
on(clipEvent) style coding. (Still supported in CS3 if you publish
to earlier versions of AS2 or 1.)
