Global_message in do_handle_event

Hi experts,
I think I have a pretty easy question:
I use the global_message parameter in the do_handle_event of my controller.
My question is:
How can I access my messages in my views to put out error messages or systemmessages?
I tried it with:
1) page->messages->assert_message ...
2) passing attribute messages of controller to view sideattribute ...
but both did not work.
Any suggestions?
Best regards Volker
**do_handle_event**
* error handling
 if lv_errmsg is not initial.
 data lv_errmsg2 type string.
 concatenate 'Fehler:' htmlb_event->name ';' htmlb_event->server_event '; Nachricht:' lv_errmsg into lv_errmsg2 separated by space.
 global_messages->add_message( condition = 'user'
 message = lv_errmsg2
 severity = 1 ).
 endif.
**user_view**
 <htmlb:textView text = "<%= page->messages->assert_message( 'user' ) %>"
 encode = "true"
 textColor = "red" />

Hi Volker,
I always use the MESSAGE attribute of the controller - that is automatically known in the page:
      me->message->add_message( condition = 'user'
                                    message = lv_errmsg2
                                    severity = 1 ).
I never used the methods parameter but I would guess you can share messages between subcontroller whereas subcontrollers all point the same instance as main controller's attribute MESSAGE.

ICCMP_BT_FOUP - How to call meth. 'DO_HANDLE_EVENT other Component/View?

Dear Experts,
when changing the field CONC_KEY-BTN in view BTSHeader in component ICCMP_BTSHEAD (Interaction Record Component)
the method DO_HANDLE_EVENT of the view controller is called.
The standard coding of the method is:
method DO_HANDLE_EVENT.
* Eventhandler dispatching
    CASE htmlb_event_ex->event_server_name.
      WHEN others.
        global_event = super->do_handle_event( event           = event
                                               htmlb_event     = htmlb_event
                                               htmlb_event_ex = htmlb_event_ex
                                               global_messages = global_messages ).
    ENDCASE.
endmethod.
The component ICCMP_BTSHEAD is used in component ICCMP_BT_INR. Also visible in component ICCMP_BT_INR is the component ICCMP_BT_FOUP (View:CREATEFOLLOWUP) used to create Follow-Up Documents like Service Tickets.
What I want to is that, if the value of the field CONC_KEY-BTN is '1', the fields of the view CREATEFOLLOWUP follow-up-document have to be not modifiable. If the value of field CONC_KEY-BTN is '2' the fields are modifiable and it is possible to create a Follow-Up Document. That is my basic requierement. Better would be if the view CREATEFOLLOWUP would not visible if the value of the field CONC_KEY-BTN is '1'. But that would be more difficult I think?
To make the fields not modifiable, I think I have to modify the Get and Set Methods of the specific Atributes. But my problem is how can I modify the above mentioned method 'DO_HANDLE_EVENT' (View: BTSHeader) so that the event 'DO_HANDLE_EVENT' of the view controller of view CREATEFOLLOWUP is called at the same time (The problem is that the 'DO_HANDLE_METHOD of view CREATEFOLLOWUP is not called when changing the field CONC_KEY-BTN of the view BTSHeader ).
Best Regards
Oliver

Hi Oliver,
In my opinion, the logic is not to be controlled at the do_handle_event level. ICCMP_BT_FOUP is created as a component usage right? So in the component ICCMP_BT_INR, there will be a navigation link defined with source as outbound plug of ICCMP_BT_INR and target as inbound plug of ICCMP_BT_FOUP. In this outbound plug, you can fill the param IV_DATA_COLLECTION as follows:
data: lr_current type ref to if_bol_bo_property_access,
                    lr_col      type ref to if_bol_bo_col.
lr_current = me->typed_context->YOUR CONTEXT NODE->collection_wrapper->get_current( ).
check lr_current is bound.
create object lr_col
    type
      cl_crm_bol_bo_col.
check lr_col is bound.
lr_col->add( lr_current ).
Now pass this collection to the target inbound plug.
In the inbound plug of the target, you can control the logic based on the value of the attribute field in the collection.
I think this should work.

Pop Up Error using MVC method after Validation in DO_HANDLE_EVENT Method

Hi Experts,.
I am rather new to BSP applications and I am working using MVC at the moment. I have a requirement which apparently is simple, but am yet to get that done successfully.
I have a couple of buttons on my BSP View screen, on click of these buttons, the User Name would be verified with entries in a Custom table and if the User Name is not found, an error message would pop up stating, "You are not Authorized to use this option".
On click of the button, the event which is triggered is handled in the DO_HANDLE_EVENT Method of the Controller for the view.
The check is performed in that method. Thereafter the method DO_REQUEST follows automatically which loads the view yet again. I want to throw a pop up error message at this instance if the User Name was not the authorized one.
I have used Java Script to throw pop up message but only in case of field content validation where I did not need to navigate away from the view for the validations. But how do I bo about for this example.
Any help would be highly appreciated.
Regards,
Subhrangsu

Hi
1. You can call the view in pop-up because you will be calling the controller using open.window.
Here is the sample code:
method DO_REQUEST .
data:
        li_vw           type ref to   if_bsp_page,
        lv_form_field   type          string,
        li_md           type ref to   zcl_model01.
dispatch_input( ).
li_md ?= get_model( 'm01' ).
lv_form_field = request->get_form_field( 'invoice_create' ).
if lv_form_field is initial.
*------ Request to display main page
    li_vw = create_view( view_name = 'main.htm' ).
    li_vw->set_attribute( name = 'model' value = li_md ).
    call_view( li_vw ).
elseif lv_form_field eq 'true'.
*------ Request to display Invoice page in pop-up
    li_vw = create_view( view_name = 'invoice.htm' ).
    li_vw->set_attribute( name = 'model' value = li_md ).
    call_view( li_vw ).
endif.
endmethod.
Layout :
   function do_Invoice()
      { var s=0; r=1; w=300; h=300; x=screen.width/2;
        x=x-w/2;
        var y=screen.height/4;
        y=y-h/2;
        popUp=window.open('main.do?invoice_create=true','win','width='+ w
        +',height='+ h +', left=' + x +',top='+ y +');

Do_handle_data vs do_handle_event

Hi experts ,
can we explain differences b/w Do_handle_data vs do_handle_event

DO_HANDLE_DATA => This is the very first method that the runtime would come to after user has made inputs on the view or a user action has been triggered. This method has an importing parameter called FORM_FIELDS. You can check this see which field have been changed on the view.
DO_HANDLE_EVENT=> This is the event handler of the controller. From here the controller is routed to the different event handler methods depending on the user actions triggered.

Hi Vaishali,
Check the below code.
TYPES: BEGIN OF T_FLIGHT,
         FLDATE   TYPE SFLIGHT-FLDATE,
         SEATSOCC TYPE SFLIGHT-SEATSOCC,
       END OF T_FLIGHT.
DATA: X_AIR TYPE T_FLIGHT.
SELECT SINGLE FLDATE
              SEATSOCC
         INTO X_AIR
         FROM SFLIGHT
        WHERE CONNID = '0017'.
In your code IT_AIR must not be an internal table. It should be a structure or a work area. Because you are selecting a single record.
Your structure must have only two fields( FLDATE and SEATSOCC ) if you are selecting in the above mentioned way.
Please make sure that your structure is in propper format.
Please close the post if it solves your problem.

MVC: DO_HANDLE_EVENT

Ok this is a silly one and I'm just too close to it I think.
I have a View/Controller: header.htm/header.do and one View/Controller: admin.htm/admin.do
In my header I put a dropdownlist and I call header from inside my admin.do
<bsp:call url="header.do" comp_id="hd" />
But the DO_HANDLE_EVENT for header.do never activates when I select from the dropdownlist only DO_REQUEST, dispatch_input( ) never goes into DO_HANDLE_EVENT??
What am I doing wrong?

OK I am calling ADMIN.DO via the URL
ADMIN.DO loads the VIEW "admin/default.htm" which has a BSP call
<%@page language="abap" %>
<%@extension name="bsp" prefix="bsp" %>
<%@extension name="htmlb" prefix="htmlb" %>
<%@extension name="xhtmlb" prefix="xhtmlb" %>
<htmlb:content design="design2003" >
<htmlb:page title="Solution Central" >
 <htmlb:form method = "POST"
 id = "frmDetail" >
 <bsp:call comp_id = "hd" />
 <htmlb:group id = "myG"
 design = "sapcolor"
 tooltip = "Input selection"
 width = "100%" >
 <htmlb:groupHeader>
 <htmlb:textView text = "Administration Tasks"

 </htmlb:groupHeader>
 <htmlb:groupBody>
 </htmlb:groupBody>
 </htmlb:group>
 <xhtmlb:protectDoubleSubmit text = "Loading..."
 active = "true"
 title = "Please Wait" />
 </htmlb:form>
</htmlb:page>
</htmlb:content>
The DO_INIT of ADMIN.DO (ZCL_C_ADMIN)
model ?= create_model( class_name = 'ZSC_CL_M_MAIN'
 model_id = 'mf' ).
header_controller ?= create_controller( controller_name = 'header.do'
 controller_id = 'hd' ).
DO_REQUEST (ADMIN.DO)
* Object definitions
data: iterator TYPE REF TO ZSC_TABLE_ITERATOR_SYSTEMS.
* Create objects
CREATE OBJECT iterator TYPE ZSC_TABLE_ITERATOR_SYSTEMS.
* Create pointer to model
model ?= get_model( 'mf' ).
* Data definitions
data: default_view type ref to if_bsp_page.
* Start event handling
dispatch_input( ).
* Create view
default_view = create_view( view_name = 'admin/default.htm' ).
* Call view
call_view( default_view ).
DO_REQUEST (HEADER.DO)
* Data definitions
data: default_view type ref to if_bsp_page.
* Create view
default_view = create_view( view_name = 'header.htm' ).
* Set Attributes
default_view->set_attribute( name = 'lv_name'
 value = m_usrname ).
default_view->set_attribute( name = 'lv_fullname'
 value = m_usrfullname ).
default_view->set_attribute( name = 'lv_lang'
 value = m_usrlang ).
default_view->set_attribute( name = 'lv_lang_graphic'
 value = m_usrlang_graphic ).
default_view->set_attribute( name = 'lv_id'
 value = m_usrid ).
default_view->set_attribute( name = 'lv_dept'
 value = m_usrdept ).
default_view->set_attribute( name = 'lv_global_menu'
 value = m_global_menu ).
* Call view
call_view( default_view ).
My page displays wonderfully and I see everything with all my data.
It's just not jumping in to process that dropdownlistBox
 <phtmlb:comboBox id = "MyGlobalMenu"
 table = "<%= lv_global_menu %>"
 nameOfKeyColumn = "menu_id"
 nameOfValueColumn = "menu_img"
 nameOfValue2Column = "menu_text"
 onSelect = "MyGlobalMenuSelect" />
Here the code is ComboBox but either way. The DO_HANDLE_EVENT just doesn't fire.

Trigger DO_HANDLE_EVENT

All,
I have 2 BSP appl, one with flow logic say ZFL & another one MVC say ZMVC. When I execute the ZFL, I wanted to navigate to ZMVC & trigger particular event(DO_HANDLE_EVENT) of ZMVC & control should remain in ZMVC.
Hope this is clear. How to achieve this?
Pls guide me..
Regards,
BM

Durai Raj,
without any user action in ZFL/page ? --->Yes
do you want to show the ZMVC page to user or automatically the ZMVC page should trigger DO_HANDLE_EVENT upon loading ZMVC page? --> I wanted to trigger the DO_HANDLE_EVENT automatically and outcome will be shown to user.
And one more, I dont wanted to show any page from ZFL.

BM

On press enter what function should call for DO_HANDLE_EVENT

hi
I want to do operations on press enter so wat is the
code for press enter?
And how i get this event in ONINPUTPROCESSING .
and i m using HTMLB
Thnks

Hi Prashant,
What kind of operations..is it for an inputfield?If yes then you can use the attribute SubmitOnEnter of inputfield.
or you can handle the enter key event using javascript.
Have a look at
[this thread|Re: Hitting the "Enter" Key] and [this thread|How to submit the page on hitting the enter key]
Serach forum , there are lots of threads on this.

Get values of table in tableview

Hello,
I have a tableview - which has a table and out of all the columns only 2 are user input - one is an amount field and other is a currency key. I dont have multiselct option in the tableview. I want to read the table in DO_HANDLE_EVENT which has amount >0 for a row.
Can I do this without multiselect option - i dont want the users to select row and then enter money..I just should be able to process only rows with no 0s.
Please advice..
Thanks
Thilothama

Hi,
you should implement DO_HANDLE_DATA,
CALL METHOD super->do_handle_data
    EXPORTING
      form_fields     = form_fields
      global_messages = global_messages.
LOOP AT form_fields INTO l_fields WHERE name CA 'table_id'.
    SPLIT l_fields-name AT '_' INTO w_table w_row_index w_column_index.
    CASE w_column_index.
      WHEN '2'.
       if formfields-value > 0.
       endif.
      WHEN '3'.
       if formfields-value > 0.
       endif.
    ENDCASE.
ENDLOOP.
given column 2 and 3 are the ones you want to check

Controller request to another one which is in another bsp appl. + attrib.

Hi everybody,
how can I call a controller from another controller which is in a separate BSP-application and how can I get some of its controller attributes? I've split the whole application in two seperate one in order not to lose the overview.
Shouldn't be that complicated, or?
Thanks for any help.

How to validate new added fields in CRM UI 5.1

Hello Experts,
Actually I am new to SAP CRM 5.1 recently We have added one New tab at Item level with new fields which are existing in CRM Gui, now i want to validate the fields
EX : 3 text boxes are there
1. shift Hrs 1
2. shift Hrs 2
3. shift Hrs 3
all these are numeric type
and next below one field is there
4. Estimated Annual running Hours
this should have the values of
Multiplication of all above 3 field values and should be displayed in the 4 th one.
please suggest me how to write the code, where to write the code.
very very very urgent.
sunil.

Hi Sunil,
Upon pressing enter, 'submitonenter' event is fired. So, in DO_HANDLE_EVENT of your view controller class add following piece of code and ur logic:
CASE htmlb_event_ex->event_server_name.
WHEN 'submitonenter'.
Add directly multiplication logic or define a method in view controller class and call that method here.
WHEN OTHERS.
CALL METHOD SUPER->DO_HANDLE_EVENT
        EXPORTING
          EVENT           = EVENT
          HTMLB_EVENT     = HTMLB_EVENT
          HTMLB_EVENT_EX = HTMLB_EVENT_EX
          GLOBAL_MESSAGES = GLOBAL_MESSAGES
        RECEIVING
          GLOBAL_EVENT    = GLOBAL_EVENT
ENDCASE.
Note: if DO_HANDLE_EVENT is not redefined, please do define again.
Cheers,
Prasad

MVC sub controller event handling for tabStrip

Hi all,
This is my first time on SDN so please forgive any procedural errors. I am developing an application for several dealer functions and use tabstrip and MVC. My main controller / view contains the tabstrip items and I call a seperate sub controller from the main view for each of the tabstrip items.
(<bsp:call comp_id="track"/> where comp_id is a sub controller created in method do_init of the controller.) The sub controller classes were created using the MVC design pattern, each with a view and a model.
Problem: When I am in any of the called sub controller views / tab items and I enter some data for the specific tab item, the do_handle_event method for that specific view / tab item sub controller is not activated. Processing goes directly to the do_handle_event of the main controller.
My understanding of the process is that the do_handle_event for a sub controller will be activated first before processing return to the parent controller. This will allow me to use the tab items as independent views with the processing logic being handled by the relevant model. Am I correct in this assumption? I have read the forums on the handling of tabstrips and have looked at the sample applications but somehow I am missing a bit of the logic. Can someone please help?
Regards,
Jan van der Spuy

Hello Bernhard/Shiva,
I have changed the comp-id and debugged the DO_REQUEST event for main controller in more detail.
The field values are
htmlbevt_t<htmlb:button:click:null
hmlbevt_f<htmlb_form_1
htmlbevt_o<htmlb_button_1
htmlbevt_i<onTracking
htmlbevt_c<0
onInputPro<htmlb
tracking_t<9346100P&A
tracking_t<1010

m_subcontrollers[1]-INSTANCE
METHOD DISPATCH INPUT
Call registered controllers with form fields
Call all registered controllers, even if no form_fields for them are r
LOOP AT m_subcontrollers ASSIGNING <controller> where hide = ''.
 CHECK <controller>-fields[] IS NOT INITIAL.

performance shortcut if no subcontroller is present
 if m_subcontrollers is intial.
 do_handle_data(
 form_fields = form_fields
 global_messages = global_messages ).
 return.
 endif.
From here it goes to the DO_HANDLE_DATA method of the subcontroller and returns.
A bit further in the logic of DISPATCH_INPUT() is where things go wrong.
* Dispatch event to controller
if event_value is not initial.
 if event_comp_index = 0.
 component_event = do_handle_event(
 event = event_value
 htmlb_event = request_event
htmlb_event_ex = event_data
global_messages = component_messages ).
 And the values are as follows:
component_event (NO VALUE) IS THIS THE PROBLEM?
request_event
event_data
component_messages

*******Kindly Clarify*********

global_event = do_handle_event(
        event = event
        htmlb_event = htmlb_event
        htmlb_event_ex = htmlb_event_ex
        global_messages = global_messages
The various values are as follows:
EVENT                                srms2_create
HTMLB_EVENT
HTMLB_EVENT_EX
GLOBAL_MESSAGES
After this code is executed the method DO_HANDLE_EVENT of the class CL_CRM_BSP_FRAME_MULTISELECT gets selected.
But I want the method DO_HANDLE_EVENT of the class "CL_CRM_BSP_FRAME_SRES" to get called.
Kindly guide me how to accompliosh the above.
Please reply.

Vijay
