Jnet events in Webdynpro ABAP

Hi ,
I am urgently looking for the demo WD project in Webdynpro ABAP which demonstrate use of the different events for JNet for example :: CELLS_SELECTED , ROW_SELECTED , NODE_SELECTED .

Hi Nitesh,
Integrating custom java script is not supported. There are still a few benefits BSP has over WDA. Well, you could put the flash object inside of a BSP application and use portal eventing to communicate with WDA.
Best regards,
Thomas

Portal Eventing in Webdynpro ABAP

Hello,
I am trying to implement Eventing in Webdynpro ABAP using 2 components ,Com1 serving as the source component and Com2 serving as Target. In Com1 I created a Inputfield and a button ,and then tied an action to the button and called the FIRE method of the IF_WD_PORTAL_INTEGRATION and sent the value in the Inputfield as the eventing parameter.
In Com2, i subscribed to the event in the wddoinit() method and then defined an action for the same and got the parameter value sent in the Com1 and set the value in the context attribute in the Com2 which is bound to the inputfield.
But still the value sent in Com1 is not displayed in the Com2 Inputfield.
Any help would be highly appreciated.
Thanks.

Hi I assume the following, please correct me if my understanding is not correct.
1.First of all you try this in Portal.
2.The moment you fire the event, the comp-2 view is active and subscribed to the portal event.
If the above are true then tell me if the portal eventing enter into the action ?Have you checked in bebug that your action is triggerred on portal_event ?
If portal event is action handler is called then if you have a importing parameter portal_event_parameter then your input value should be there.

How to handle events in webdynpro abap

Hi,
can any body explain how to handle the events in webdynpro abap.
i want to know some concepts in general.
Thanks,

Hi Mahesh,
you can create event handlers under the actions tab in you view. evry event handler has an importing parameter wdevent of type ref to cl_wd_custom_event.
you can also create events in your component controller and they can be handled within your views
check cl_wd_custom_event class for details about what all information you get when an event occurs.
for further details you can check out the following links

Javascript server events in webdynpro ABAP

I am migrating an existing BSP application to webdynpro abap. Few of sections, in existing BSP application, uses java script coding to trigger few server events. For example it uses a flash charts on click of which some filtering logic is written on table. Similar logic needs to be placed for webdynpro. I used Iframe to display this charts. Charts are rendered properly but I am not able to raise the actions or trigger events on server as I dont have access to parent.document object of my parent view.
I get access denied/ permission denied error.
Cant we trigger server action or event using JavaScript from child IFrame.

Click event in Webdynpro abap for interactive form

Hi ,
I am using a ZCLI form to be developed using Webynpro abap . I am new to webynpro abap but I have worked in offlined upload of pdf forms . My problem is I created a wedynpro component and integrated the form .The form is only opening up if the layout choosen is standard layout . if it is a zcli form it is not opening up . I am also not able to capture the click event from the form .
some immediate help required.
My requiremnt is to save 2 fileds from a form in an interactive way to a SAP database using webynpro abap .
Regards
Abhil

Hi Abhil,
If your layout type is 'ZCI Layout' then you have insert the webdynpro script in the layout. After selecting the ZCI Layout click on enter and then go to layout tab, in this go to Utilities menu->select Insert WebDynpro Script.
If you do this then in the Hierarchy tab of adobe form you can see the (Variable) ContainerFoundation_JS, it means that you have inserted WebDypro Script in the form.
Finally activate the form and run the application.
Thanks,

OnSelect event for a Drop down UI Element in Webdynpro ABAP Select Options

Hi Experts
We have built our UI based on the webdynpro ABAP Select Options. We have a requirement that, when we change the value of a drop down box in the UI, I need to hide some fields. Can anybody help me out in handling of OnSelect event of a drop down box built using webdynpro ABAP Select Options. We are on SAP Netweaver 7.0 EHP1.
Rrgards,
Srikanth.
Edited by: Srikanth Kancherla on Apr 29, 2010 10:43 PM

Hi Srikanth,
as you seem to be already aware, the component is dynamically built.
so you would have to enhance the code that builds the element and insert a reference to a new action (enhancement) that could handle the onSelect event.
What is it about this that you particularly want help with?
Cheers,
Chris

PCUI - portal event - webDynpro Abap

Hello,
From standard PCUI, which used to create partner, I want to get a value partner and send it to a view that content Webdynpro Abap through portal Event.
Is it possible? How?

WebDynpro ABAP - inter session events possible?

Hi Experts,
I have a ABAP-WebDynpro application with various tabstrips to show and maintain process data within a production process. Each tabstrip contains several data of a specific process step. At the beginning, very few data are already present. While production progresses, chemical analysis is being taken and machine data is gathered. Assoon as new data for the process step is available, a refresh should be performed.
Though not perfect in every aspect, we made this scenario work in a similar way in ABAP Dynpro by using inter session eventing (ISE). Is there a possibility to trigger events in WebDynpro cross-session - for example after adding data to the database?
Best regards
Jens

There is no real cross session eventing available in Web Dynpro. The problem is two fold. First, UI updates can't be initiated by the server in HTTP (unlike the SAPGUI which does have a push mechanism to the client). This is a current limitaiton of HTTP itself and not something Web Dynpro related. So to trigger the phase model of Web Dynpro, something must occur on the client to trigger the server event. In NetWeaver 7.0 and 7.01 you have to use the timedTrigger UI element to acomplish this:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/da/a6884121a41c09e10000000a155106/frameset.htm
You then generally used a shared memory object (or even temporary database entries) to communicate data or events between to different processes. For instance a background job is running and places it status in a shared memory object attribute. The Web Dynpro can then fire a TimedTrigger every minute to check the value of this shared memory object attribute.
In NetWeaver 7.02 we improve this process with a new capability called the Web Dynpro Notification Service. Instead of the timedTrigger, we can simulate a push of data/events to the client using AJAX. We open an secondary server request to the ICM to check the status of an event. That way we don't have to disrupt the client side activity or incurre the full Web Dynpro Phase Model until we know a change in the status of our event has occured. Also since the status info is stored in the ICM Cache, you don't even have to fall into an ABAP Workprocess to check the status.

Need expertice opinion on WebDynpro ABAP vs FPM for heavy custom apps

Hi Experts,
I have a lot of custom UI development,.for external users in SAP. Most of these applications can be simply developed using WebDynpro ABAP framework. If I do the same development using FPM framework I may need to do lot of reaseach espcially controling the UI behaviours like hiding, changing table cell colors based on the data, manipulating the UI behavior in the runtime, lot more like this.
The question I have is , which one is the right tool for my development FPM vs WebDynpro ABAP, what is the value in building the same apps in FPM rather then WebDynpro ABAP? If I develop these apps in WebDynpro ABAP does my client loose any new capabilities in he future releases? are any other drawbacks?
The challenge i see the FPM Feeder classses doesnt have lot of interfaces other then few like ( IF_FPM_GUIBB_FORM, IF_FPM_GUIBB_FORM_REPEATER,IF_FPM_GUIBB_LIST,IF_FPM_GUIBB_SEARCH,IF_FPM_GUIBB_TREE,IF_FPM_GUIBB_LAUNCHPAD )
to extend more custom UI functionalities, and the other thing I may need to invest lot of time in reseacrhing and analysing the framework events etc....Please can you shed some light on it and put me in right direction.
Appreciate your time and help.
Thanks
Krishna

Hello Krishna,
the whole story revolves around reusability and abstraction, extensibility atleast in this context.
FPM offers more abstraction than Webdynpro. i am sure we all appreciate the standard webdynpro components for ALV, Value help, as this is something we could reuse and if we build our components that it manipulates itself with the help of configuration, customization and personalization.
So all the Standard SAP Dev could be enhanced (not modified) by simple, configuration, FPM is built around this concept.
So if you want to do custom development, which could be extended for your different customers with minimal efforts, you could go for FPM.
So here are some takeaways
1) FPM offers more abstraction than Webdynpro
2) FPM offers more reusability
3) Say manipulating the UI behaviour and say some customers wants view1 first and other doesnt want view 1 and wants only view 2. so in FPM you could simply do it with different configuration. and with Webdynpro, you need to manage this dynamically based on certain application parameter or you may end up copying certain comp,,or you use different usage,,,,and you could calibrate this.
Regarding limitation with FPM interfaces, could you explictly share what custom development you intend to do and in worst cases, you could always use freestyle UIBB,, which is webdynpro abap
in that scenario, atleast wiring, application config(app parameter, combination of webdynpro, with thier respective config),,could be reused.

Webdynpro ABAP/Portal. Plugin HTTP connection issue on WaitingEventQueue.js

Hello,
We are experiencing a strange Portal Behavior with our Webdynpros. Our portal contains several iViews including some Webdynpro (ABAP) and some reporting transaction calls that use SAPgui for HTML.
When portal is called for the first time and a user logs in, two connections of type RFC can be seen for that user in SM04 in our ERP system. All iViews work as expected. For example, calling the Time Management webdynpro closes one of the RFC connections and starts a new Pluguin HTTP connection. We can go back and forth between the welcome page and this Webdynpro with no issues.
If we then select one of the reporting transaction codes, the portal launches the SAPGUI for HTML. Report retrieves and shows data, and then we close using the "Exit" button provided by the sapgui for HTML
Next we try again to launch any webdynpro (abap), but SM04 shows that the new Plugin HTTP session gets stuck and spinning mid way, and will stay there. Refreshing the Portal screen with F8, navigating back and forth, logging off and on again has no effect. The webdynpros will not launch again. Only webdynpros are affected, any of the reporting transactions can be called successfully over and over.
We have figured that deleting Temporary Internet files (we are using IE 7), and in particular by just deleting the WaitingEventQueue.js?XXXXXXXXXXX file, the system will break away from the spin loop and show the webdynpro again, but eventually it will get stuck again, and asking the users to delete their Temporary Internet Files every 5 minutes is not a workable solution
I have reviewed the contents of this javascript file at different points during the test, and the contents do not change, so deleting the file and the recreate process must be resetting somehow the queue and allowing for a new correct communication.
Is there a way to properly reset this event queue (for example from ABAP, when the webdynpros are reloaded) in order to avoid the spin loop?
Thanks for any help!
Andres

Well, we got the issue resolved, so here is what we did, in case anybody is interested:
Tested again our portal with multiple versions of Internet Explorer, in particular IE8 and IE6, the Webdynpro behavior was normal (no timeouts or locks). It even worked when we installed IE7 in a brand new machine and tried our portal.
So we started suspecting if maybe the particular IE7 that we install internally (with specific settings and policies) may be the culprit. We took a desktop that was producing the timeouts and used the following options in IE7:
Tools->Internet Options->Advanced(tab)-Reset Internet Explorer settings
and, voila! the next time we ran there, the portal did not create any timeouts.
We even asked our desktop support team to uninstall and reinstall IE7 in the same machine after we did the reset, and even after the re-install that the timeout problems did not re-appear.
One of the things that the "reset" option does is delete the Add-ons used by IE.
So as a last test, we took a machine that was presenting the problem and went to the Internet Options to disable all the add-ons (in the Programs Tab). The error disappeared.
And even after enabling back all the add-ons, the error would not return.
Conclusion:
Without being able to pinpoint the specific add-on (or combination) that causes the problem, we suspect that some of them conflicted, causing IE7 to behave abnormally. Disabling them all, restarting Internet Explorer, and enabling them again, makes the WaitingEventQueue.js work as it should

Interactive Adobe Forms using WebDynpro ABAP

Hi,
I could able to design and execute my interactive adobe form using webdynpro ABAP. Here what i am doing is i am creating context with my structures and table types and pdfobject of type xstring and passing the proper inputs in interactive form properties, in template sources i am provinding the interface and form name of my own choice and it is getting created automatically by the system, every thing works fine here and i could able to execute my form from web dynpro application.
Here my requirement is i have already created structures and table types after that i went to transaction SFP and created an interace and by using that interface i have created form and i have designed the layout. Now what i want to do is i want to integrate this form in my webdynpro appliction and i want to execute it from webdynpro applicaton. When i try to do i am getting short dump, is my approach feasible or not . kindly suggest. If we can achieve this what is the way to achieve.
Please do send your suggestions.

Hi
When u click on button..u will have to get the data from node which is existing on the Intereactive form and pass it to other view via writing logic in button event handler.
The data can be displayed in other view as result.
I hope u got it.
Provide REWARD points..:-)

Retreival of Dynamic Table Datas from Adobe to WebDynpro- ABAP

Dear Friends,
I have Developed an application in Webdynpro-ABAP, where i have integrated Adobe form in the webdynpro.
In the adobe form, dynamic table is there where we can add and delete the rows at runtime.
I am trying to retreive the table datas at runtime from the adobe.
I can able to retreive only the first record from the table, even if the table contain more than one rows.
As per the below code i have retreived the count, where it is showing the count as 1.
using the method get_static_attributes_table i am trying to fetch all the records, but i can able to retreive only the first record.
lo_nd_zsm_fm_transport_tra = wd_context->get_child_node( name = wd_this->wdctx_zsm_fm_transport_tra ).
lo_nd_tr_details_i = lo_nd_zsm_fm_transport_tra->get_child_node( name = wd_this->wdctx_tr_details_i ).
count = lo_nd_tr_details_i->GET_ELEMENT_COUNT( ).
elems_bank_table = lo_nd_tr_details_i->get_elements( ).
lo_nd_tr_details_i->get_static_attributes_table(
importing
    table = ls_tr_details_i ).
Even Cardinality i have maintained as 1.N for the node.
Kindly provide me the solution.
Thanks and Regards,

Hi, I have solution for read data from dynamic table and add these added row to WD4A context (and then save them to DB) (in ONACTIONPROCESS_SUBMIT event):
DATA: l_fp TYPE REF TO if_fp.
l_fp = cl_fp=>get_reference( ).
DATA: l_pdfobj TYPE REF TO if_fp_pdf_object.
l_pdfobj = l_fp->create_pdf_object( ).
l_pdfobj->set_document( pdfdata = lv_pdfsource ).
l_pdfobj->set_extractdata( ).
l_pdfobj->execute( ).
DATA: pdf_form_data TYPE xstring.
l_pdfobj->get_data( IMPORTING formdata = pdf_form_data ).
DATA: converter TYPE REF TO cl_abap_conv_in_ce, formxml TYPE string.
Converter = cl_abap_conv_in_ce=>create( input = pdf_form_data ).
Converter->read( IMPORTING data = formxml ).
TYPE-POOLS: ixml.
DATA: l_ixml TYPE REF TO if_ixml.
l_ixml = cl_ixml=>create( ).
DATA: streamfactory TYPE REF TO if_ixml_stream_factory,
istream TYPE REF TO if_ixml_istream.
streamfactory = l_ixml->create_stream_factory( ).
istream = streamfactory->create_istream_string( formxml ).
DATA: document TYPE REF TO if_ixml_document.
Document = l_ixml->create_document( ).
DATA: parser TYPE REF TO if_ixml_parser.
parser = l_ixml->create_parser( stream_factory = streamfactory
                                           istream = istream
                                           document = document ).
Parser->parse( ).
the code above allows you to read xml data from pdf file, then you need only to read xml and adding rows to your context:
data : item type string. DATA: nodechild TYPE REF TO if_ixml_node,
        Childschild TYPE REF TO if_ixml_node.
    data: num_of_children type i,
          x type i,
          y type i,
          num_of_attribute.
node = document->find_from_name('ZAM_PROTSTROJF').
num_of_children = node->num_children( ).
nodechild = node->get_first_child( ).
data: wa_strojdetail type ZAM_PROTSTROJF,
      wa_strojdetail_tab TYPE TABLE OF ZAM_PROTSTROJF.
wa_strojdetail-docnum = ls_zam_protstroj-docnum.
wa_strojdetail-bukrs = 'VVS'.
wa_strojdetail-mandt = sy-mandt.
y = 1.
do Num_of_children times.
       num_of_attribute = nodechild->num_children( ). " Childschild->num_children( )." Getting the number of attributes
       Childschild = nodechild->get_first_child( ).
       wa_strojdetail-itemnum = y.
       x = 1.
       do num_of_attribute times.
          item = Childschild->GET_value( ).
          CASE x.
            WHEN 4.
              wa_strojdetail-anln1 = item.
            WHEN 5.
              wa_strojdetail-anln2 = item.
            WHEN 6.
              wa_strojdetail-bubtr = item.
            WHEN 7.
              wa_strojdetail-belnr = item.
          ENDCASE.
          Childschild = Childschild->get_next( ).
          x = x + 1.
      enddo.
      y = y + 1.
      APPEND wa_strojdetail to wa_strojdetail_tab.
      nodechild = nodechild->get_next( ).
enddo.
This is complete solution for adding rows in interactive forms and working with them in WD4A!

Webdynpro ABAP independent application

hello,
I have developed independent application of webdynpro ABAP
i want to integrate it on portal
i have page, create iview, assign application url to the iview - all this i do in portal content administration etc
but in later versions, instead of iview etc, there is bankend transaction code, ie tcode in R/3 where I can assign my web dynpro application to portal
I need the name of that transaction code. kindly help with your inputs
thanks
bhakti

Hi Bhakti,
AFAIK there is no such kind of facility available so that you can directly assign your webdynpro into the portal using any t-codes.
But the SAP Enterprise Portal supports the Web Dynpro application development with functions like:
Event handling of portal events
Navigation between Web Dynpro applications within the portal or to any portal content
WorkProtect mode
And With Web Dynpro you create interactive Web-based user interfaces for business applications. The portal allows the role-based and secure access to different kinds of information (structured or non-structured), services, and applications using a Web Browser.
For portal integration, refer the below document which will give you an idea.

I am not really sure about your requirement. With my limited understanding of that , i think that you have few possibilities.
1. You can let the ess/mss application communicate with WDA application via a Poral event.
2. You can enhance the ESS WDJ component and use RFC destination to get the data from info type and build your own view in WDJ.
