Messages in webdynpro abap

hi all,
can any one help me by provinding me with a small example on how to implement messages in a webdynpro application.
Thanks in advance,
chandana.

Hi,
Use the IF_WD_MESSAGE_MANAGER interface .
All messages will be displayed in a dedicated message area.
By default the message area appears at the top of the page.
The message are can be moved like a UI element in a view. You find a UI element (Message Area) in the UI library Pattern. Messages will be placed in this area, if it is available.
Use the WD code wizard to create the required coding to report a message. (Generate Message radio button)
Generated/sample code will look like this.....
   * get message manager
data: l_current_controller type ref to if_wd_controller,
      l_message_manager    type ref to if_wd_message_manager.
l_current_controller ?= wd_This->Wd_Get_Api( ).
CALL METHOD l_current_controller->GET_MESSAGE_MANAGER
RECEIVING
    MESSAGE_MANAGER = l_message_manager
* report message
CALL METHOD l_message_manager->REPORT_ATTRIBUTE_ERROR_MESSAGE
EXPORTING
    MESSAGE_TEXT   = 'REPORT_ATTRIBUTE_ERROR_MESSAGE'
    ELEMENT        = Elem_Flights
    ATTRIBUTE_NAME = 'CITYFROM'.

How to use messages in WebDynpro-ABAP

Hi,
How to use messages in WebDynpro-ABAP.
Does it has any class to manage messages like IWDMessageManager or we can just use standard SAP Message types.. like E,W,X,I,S..
I hope it have a message container to display messages.
Thank U for Ur time.
Cheers,
Sam

Hi Sam,
U can hard code the message or u can use the Assistance class's text elements to store the messages.
1) Code to display hard coded message:
report message
CALL METHOD l_message_manager->report_attribute_error_message
EXPORTING
message_text = "Enter the correct Connection ID"
element = elem_flightinfo
attribute_name = 'CONNID'.
2) Code to display message from text element of assistance class:
lv_text = wd_assist->if_wd_component_assistance~get_text( key = '002' ).
report message
CALL METHOD l_message_manager->report_attribute_error_message
EXPORTING
message_text = lv_text
element = elem_flightinfo
attribute_name = 'CONNID'.
Where Message "Enter the Correct Connection ID" is stored in Text Element with key '002'
Hope this helps,

Troubles generating an error message in WebDynpro ABAP

Good evening guys.
I set the following code in enhancement method (pre-method) of ONACTIONNAVIGATE method, which is triggered after push the "Review" button in WebDynpro Application FITE_REQUEST:
method PRED78YJIDJ8M8KXTC2MXQI1XK5O . "Exit of ONACTIONNAVIGATE (in ZENH_FITV_FPM_02 )
data: L_CURRENT_CONTROLLER type ref to IF_WD_CONTROLLER,
        L_MESSAGE_MANAGER    type ref to IF_WD_MESSAGE_MANAGER,
        TEKSTO TYPE STRING.
IF NAVIGATION_TYPE = 'FORWARD'.
    L_CURRENT_CONTROLLER ?= WD_THIS->WD_GET_API( ).
    call method L_CURRENT_CONTROLLER->GET_MESSAGE_MANAGER
      receiving
        MESSAGE_MANAGER = L_MESSAGE_MANAGER.
report message
CALL METHOD l_message_manager->REPORT_T100_MESSAGE
EXPORTING
    MSGID                     = '00'
    MSGNO                     = '398'
    MSGTY                     = 'E'
    P1                        = 'Test'
    P2                        = 'Test2'
   P3                        =

   SCOPE_PERMANENT_MSG       = CO_MSG_SCOPE_CONTROLLER

   SHOW_AS_POPUP             =
   CONTROLLER_PERMANENT_MSG =

   ENABLE_MESSAGE_NAVIGATION =
RECEIVING
   MESSAGE_ID                =
ENDIF.
endmethod.
Unfortunately, this code is not working, because the message is not appearing. I generated this piece of code with the WebDynpro Code Wizard, but even so is not working.
The standard application generates standard messages an places them in WDR_MESSAGE_AREA WD component, in the View MESSAGE_AREA, regarding blanks in text fields that are located on another WebDynpro component (FITE_VC_GENERAL_DATA, view GENERAL_DATA_VIEW). I put my own code in WD component FITV_FPM, in the LAYOUT_VIEW. But I wanna the messages also appear at WDR_MESSAGE_AREA WD component, MESSAGE_AREA view.
Do you know why I am having trouble generating an error message in this standard Webdynpro? It is not possible to generate an error message to appear in another Webdynpro component, but the same WD application?
Regards guys!

Hi
you can store message ID, message no and message type in the context node in ur exit and make this context node interface enabled. Map this node to the component where you want todisplay the message. read the context node .
Call the method for displaying the messages and pass message id, no and type from context node.
invalidate this context node using method "invalidate" from interface if_wd_context_node.

Display of messages in webdynpro ABAP views

Hi,
In a ABAP WD component I have 2 views, connected through a navigation link.
If in the first view, a message is displayed using the message manager, a message area is shown on the top of the view with the message in it.
If now I navigate to the other view, The message area is still being displayed without any message in it.
Perhaps the message log is not empty.I do not wish to display the message area when there are no new message is reported.
How do I go about it?
Regards,
Rahul
Message was edited by: Rahul Kumar

Hi Rahul,
The message area is still displayed, because the message is stored inside of the history. Without displaying the message area, the user won't be able to access the message history. There are plans to allow a developer to switch off the history though (being just plans, so no eta).
Best regards,
Thomas

Hi,
There is no provision to add a Toolbar button in Message Area unless you enhance the WDDOMODIFYVIEW of WDR_MESSAGE_AREA component (or do a modification) of method CREATE_ALL_MSG_TAB( ) of class CL_WDR_MESSAGE_AREA and adding a new toolbar item using add_toolbar_item( ) method.
Please note that the modification/ enhancement will reflect in all the WDA application not just your particular component.
hope this helps u,

I don't think you quite understand how hibernation mode works.
"The state of a computer is stored into its main memory, which is also called RAM. When a
computer is powered off, the contents of this memory are irremediably wiped out. Hiberna-
tion works in the following way: before being powered off, the computer saves all the con-
tents of the memory to a ﬁle on the hard disk drive. On wake up, data stored in this ﬁle is
read out and restored to the memory. Therefore, the RAM contents are the same before
and after the hibernation process, and the state of the computer is also the same. The
saved ﬁle is named sleepimage, and is located in the /private/var/vm directory. Hi-
bernation is sometimes also called “software suspend” or “suspend to disk”.
The default suspension feature of Mac OS X, called sleep works in a different way. When
entering sleep, every subsystem of the computer is shut down, except the main memory
which is still powered. This process preserves the contents of the memory, and allows the
computer to wake up quickly. However, a sleeping computer still consumes a small
amount of power. Sleep is sometimes also called “hardware suspend” or “suspend to
RAM”.
Apple introduced the safe sleep feature in Mac OS X 10.4.3 for the Powerbook HD line of
laptops. This feature is a variation of the default suspension behavior. The main memory is
still powered during the sleep, but the contents of the memory are also saved to the disk at
the beginning of the operation. The saved ﬁle will only be used if the laptop runs out of bat-
tery power while sleeping, in order to restore the original state of the computer.
This safe sleep feature is what makes hibernation possible in Mac OS X 10.4.3 and above."

WebDynpro ABAP in WebAS 640

Hi,
I have installed both Netweaver Java and ABAP edition on the same machine successfully. I can started both instances on the same time. No problem so far....
However, when trying WebDynpro ABAP, I got the system message "The runtime of WebDynpro ABAP is removed for WAS 640 (note 774655)".
Q: When this feature will be available?
Thanks and regards,
Fendy

I'm am seeing bits and pieces of WebDynpro ABAP in the 6.40 Sneak Preview as well, but it seems to have been stripped out. Like Peter has stated, it was not supposed to be in the 6.40 release.

Webdynpro ABAP not working from internet

Hello,
I´m new at webdynpro and portal...
We have a ess portal with webdynpro abap and java. Our employees may access it from intranet and all works fine, and from internet when they are in the outside.
From internet the webdynpro abap gives the message that the server cannot be reached. The server is our production backend and is not open to the exterior.
Is there a way to make this work, from inside and outside?
Teresa

Yes sure,
so you have to set the parameter wdisp/add_clientprotocol_header = 1 in the web dispatcher profile.

Is WebDynpro ABAP a viable option?

Hi all
Some generic questions, is WebDynpro ABAP a viable option? Can I suggest it to the customers? Is it a good practice to have UI and Business logic on the same server? Y are two strains of webdynpro one for ABAP and one for Java necessary?
I have also heard ESS MSS runs on both ABAP and Java WebDynpro. Y is SAP complicating the skillset required to deal with Business Packages? Please give me links or direct answers as suitable. Thank you all.

Hi Volker
All that I have written is based on help.sap.com. And here is the link (Go to WDJ in Travel manangement and look at constraints).
<a href="http://help.sap.com/erp2005_ehp_02/helpdata/en/46/51f0e994b85e40e10000000a11466f/frameset.htm">ECC 7.0 WDA</a>
And yes you are right, ECC 6.00 is enhanced using EHPs -> enhancement package. I am talking abt EHP 2.
I am using CAF on NW 7.0 and hence the concern. And when I say composite my UI is essentially calling faceless services. That alone gives me the power to orchestrate processes quickly. The only reason I put these questions is because the same are coming out of my customers too!! And I need to give a concrete answer on the UI paradigm as well. Though I have made up my mind the future releases of ESS MSS is troubling to hear. Thank you for the patience shown in answering my questions.

ADS Error while calling WebDynpro Abap with Adobe Form

Hi Experts,
I have created an Adobe Form and its interface in Transaction SFP. In a WebDynpro Abap Component I created an UI-element "Interactive Form" with the context of my form. So the WebDynpro Context was created automatically. Then I tried to call the WebDynpro Application in the Internet Explorer but got the error message:
german(original):
WebDynpro Exception: Der Aufruf des ADS schlug fehl. Informationen zur Ursache finden Sie im error.pdf auf dem Applikationsserver.
english:
WebDynpro Exception: The call of ADS failed. You find information in error.pdf on Application server.
How can I call error.pdf and what can that be? One WebDynpro Component with the form runs without any problems, the other one doesn't do this. I have no idea if it is a problem with context or server or something else.
I hope you can help.
Thanks al lot.
Best regards,
Ingmar

Relavance of assistant class in Webdynpro ABAP.

When we can create a object for a class in the attributes tab of the component controller and acess the methods of the class directly, why do we need a assistant class.??
Moderator message : Search for available information, post the question in Web Dynpro forum, thread locked
Edited by: Vinod Kumar on Dec 22, 2011 3:09 PM

Hai,
In webdynpro ABAP,we use to write all the coding part within the component itself but there is a provision with which we can write the necessary business logic outside the component that is in a class and we can use that class as the assistance class in the current component. It is same as model class.
