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.
With Regards,
Nitesh Shelar.

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.

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

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,

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.

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

Webdynpro ABAP webservice call to external server - Cookie issue

Hi,
We are experiencing cookie issue while calling webservice to Tivoli system hosted on IBM websphere.
Steps we have done as follows:
1. Created a ABAP Proxy class from Tivoli WSDL.
2. Configured T-Code LPCONFIG to point to above proxy class and logical port.
3. Configured SM59 RFC connection to point to Tivoli server using basic authentication mechanism (User ID/Password).
4. Called webservice method from WebDynpro ABAP program.
After above steps, we are able to call the webservice method successfully but second time we are experiencing Cookie being adding to the request and eventually no response back to our program.
When we investigated this cookie issue with IBM Websphere people, they says thay have enabled SSO Config instead of basic authentication and that's why a cookie is being added to the request and fails. when they disabled SSO, we are able to call webservic method sucessfully sevaral times. but now this cannot be no longer disabled as other applications are using SSO enable option. So, we are thinking, is there something that can be done in SAP ECC itself as we see the option of using SSO in SM59 instead of User Id/Password but not sure How?
If anybody has undergone this scenario/SSO config from ECC SM59 successfully, Please reply back.
Thanks in advance
Praveen

Here is the link that explains how SSO can be configured in SAP.
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/65/6a563cef658a06e10000000a11405a/frameset.htm
Once done, under Client PSE in Tcode STRUST, you can upload the certificate obtained from the SSO enabled system and use the client PSE (Default) in the SSL Client Certificate area of SM59
I see Thomas has already responded to you and he has written a blog on how to set this up as well.

Webdynpro ABAP called from IView JAVA works over http but doesn't over http

Hello gurus, like I said in the subject, we have integrated inside our JAVA portal a WebDynpro ABAP and it's working good over http protocol (http://<servername>:<http_port>/irj/portal), but when you browse the portal over https protocol (https://<servername>:<https_port>/irj/portal), everything works fine exept the WebDynpro ABAP, is like if the javascript components didn't be loaded completly, because the buttons doesn't make anything, and only half of the table that is supossed to be loaded is showed.
Do you know what kind of configuration I'm missing?
Thanks and best regards

You have to note here that for webdynpro ABAP applications, the http/https request is actually served by the backend server.
So, while accessing your webdynpro ABAP application, the request will be like:
https://<mybackendserver>:<backendport>/bc/sap/.....
While creating a system object in your portal (System landscape), you will need to adjust the protocol to https and also set the appropriate https port of the backend server. Also, HTTPS/SSL communication should be enabled on your backend server.
Please check the definition of your system object.
You can find more information by turning on a HTTP trace and checking how the request is routed to the backend server upon accessing the WD4A application.
Thanks,
Shanti

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

Advantages of BSP over Webdynpro ABAP

Hi,,
Can anyone please explain what are the advantages of BSP over WebDynpro ABAP, In what cases do we need to stick with BSP?
Thanks,

Hi,
There is a SAP web GUI map and it contains different technologies as follows:
If you have the SAP screen already available , then the best solution would be to go for the ITS solution(Web Gui).
But if you were to compare the man days required to code a dynpro and a web dynpro screen from scratch then they would approximately be the same.
Yes if you want to leverage on Web Dynpro you will have to currently code all screen from scratch , and encapsulate your backend logic as function modules.
Apart from BSP you have the option to use Portal Development Kit (if you have SAP EP in your landscape) . JSPHTMLB(tag libraries)JCO running on WAS 6.2 or 6.4 or other Java server.
If you have just one screen and currently dont have the WAS 6.4 in your landscape and it would involve delays interms of procurement , setup and training, then its better you go with either of the above solutions depending on the skillsets in your team.
If you can make an FM of your trx, the BSP solution might be the easiest step. No additionial knowledge (except from some HTML(B)) is needed.
Advantages of web dynpro:
Additionally,
I would say if you would want a quantum leap in advantages by preferring a UI solution , then it has to be webdynpro be it ABAP or Java.
Some of the features that I have heard about and noticed as well is
-> Metadata based which means tomorrow SAP could easily support a new client without you not requiring even to change a line of code.
-> Support for Java gui and Win gui for web dynpro coming up(over http)
-> More professional UI and flicker free
-> Faster development time when compared to BSP or JSP
-> Future proof
Disadvantages:
On the down side
-> You loose control on so many things that you took for granted in web programming such as javascript support, DHTML
Hope this will help you.
Cheers,
Darshna.

Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input

Dear Friends,
We are facing a serious problem for debugging. Expecting valuable input for the same.
Debugging is not working in R/3 from WebDynpro-ABAP developed webpage input in Production Server.
The debugging (for WebDynpro-ABAP application) is working in Dev. Server for
1st ] Within R/3
Ex. debug for bapi within R/3. i.e. value enter as input in R/3 only.
2nd ] From webpage to R/3
Ex. Some input given on the internet web page developed through WebDynpro and external breakpoint set in R/3 it works. It directs to R/3 code through debugging.
In Prod. Server the 1st case above is working but the 2nd case is not working.
In Prod. Server the WebDynpro developed applications are running successfully through internet explorer webpage inputs. So running the application is not a problem in prod. Server but debugging of the same is the problem.
The setting which are done in Prod. server are,
1] RZ10 in parameters are set for port and host name.
2.1] In SMICM check for ICM.
2.2] Host file updated in Windows-System 32.
3] In SICF following services are active,
