Navigation Error in Web Dynpro Application

Hi All,
I developed a web dynpro application with 2 views.
I implemented the navigation paths(in and outbound plugs). I have a Next button in the first view and when
I clicked the next button it opened the second view.
It was working fine until, i created custom controller
and defined model node and model binding by calling RFC.
In the first view, i created a model node corresponding to the custom controller model node and defined the context mapping between the first view and the custom controller.
When I run the application (the first view displays data calling RFC) once I clicked the next button i got this error message.

Hi
Are you having any inputfields in your next view?If yes then check if you have bound the context attribute to it.
I think you haven't done that.

Hi,
Add additional info including the ST22 dump for security you can run find and replace in the st22 dump text and relplace ahost name and sid.
Also when do you get this dump exactly i.e. what are you doing or how are you accessing the webdynpro for the error to be generated.
What is your system patch and kernel levels.
Please provide more information otherwise this is just a guessing game.

Deployment error for Web Dynpro application

Hello, I have developed a new Web Dynpro Welcome application in my local system, which is my laptop. I have both the NW Dev Studio and the app server on my laptop.
When I try to deploy and run the application I get the below error. As far I am concerned I have logged in as j2eadm user and trying to deploy.

Window size, and navigation issues with Web Dynpro and GP

I have a Web Dynpro application which navigates to other Web Dynpro applications. I also need to integrate this application into a GP. When I create a process that calls the Web Dynpro app, two things I've noticed are:
1. The window size presented in the GP process is too small, and there is no way to scroll to see the rest of the app. How can I change the initial size of the Window to show the entire application? This is an absolute show stopper...
2. Other functionality is made available to the Web Dynpro app by navigating to other Web Dynpro applications. Outside of the GP, this works correctly. However, from within the application when started via a GP, I get the following error when I try to trigger an action that will lead to a navigation event:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Cannot navigate via outbound plug CreatePdf of view TestView because there is no navigational link attached to it
at com.sap.tc.webdynpro.progmodel.view.View.navigate(View.java:541)
at com.sap.tc.webdynpro.progmodel.view.View.navigate(View.java:462)
Any ideas? Do I have to manually instantiate the various components when the root Web Dynpro app is called from a GP?

Update: this was my mistake - I had neglected to configure all the view containers in the WebDynproCO window, which was generated by adding the GP interface to the component. All is well.

The Web Dynpro application 'PageBuilder' has expired

Hi Alll,
We are implementing ESS/MSS and the Portal was working fine.
We set it up for SSL/https and it was working just fine. However when we call it from reverse proxy server the web dynro applications through the following error:
The Web Dynpro application 'PageBuilder' has expired. Restart the application. Choose 'Refresh' in the iView tray or use the browser 'Refresh' button to restart the iView
Details: No details available
When I tested this with a transaction iview they work just. Also when tested directly from Portal they work fine.
Can anyone assist on this please?
Thanks,
Mike

Hello Mike,
After a user is logged in and requested an ESS/MSS application. The pagebuilder service is requested to built the page.
When the user is still logged in but is not working with this application the pagebuilder receives a timeout after a while and the session is expired. The pagebuilder has sometimes the status stopped, you can see this in the Netweaver Administrator. (Search for the pb in the application area)
If an other user is requesting an application the pb service is started again and the page built again.
If you want to get rid of the warning you could set the "timeout" parameter to a higher value in the configtool.
Kind regards,
Marcel

Hi Thorsten,
Close your explorer, open a new explorer and run the application from the new browser.

Hi,
I am getting below error:-

Can anyone help me on this.

Hi Rali,
I think you have not been using this application from long time. So the Portal session time must have expired. Well, Let us know if the problem persist even after RESTART of the browser.

Default expiry time of a webdypro is 3600 sec.Try to increase it in the visual j2ee admin tool.

I am getting a error while executing the Web Dynpro Application Page.

Hi All,
I am getting a Error while executing a web dynpro application :::
: Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered. Component: Z_WEP_PERSONAL_DATA, View: OVERVIEW, Window: Z_XXP_PERSONAL_DATA
I have checked this error description in ST22 :
What happened?
    The exception 'CX_WDR_RT_EXCEPTION' was raised, but it was not caught anywhere
     along
    the call hierarchy.
    Since exceptions represent error situations and this error was not
    adequately responded to, the running ABAP program
     'CL_WDR_CLIENT_APPLICATION=====CP' has to be
    terminated.
Error analysis
    An exception occurred which is explained in detail below.
    The exception, which is assigned to class 'CX_WDR_RT_EXCEPTION', was not caught
     and
    therefore caused a runtime error.
    The reason for the exception is:
    Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered. Component:
    Z_XXP_PERSONAL_DATA, View: OVERVIEW, Window: Z_XXP_PERSONAL_DATA
Can u plz help me regarding this error.
Thanks,
Deepika

>Navigation in Phase WDDOMODIFYVIEW Cannot Be Triggered
Looks to me like you are trying to fire a navigation plug within WDDOMODIFYVIEW. According to the rules of the WD Phase Model this is not allowed.

Error while implementing a web service in web dynpro application

HI All,
I am trying to use a webservice in a web dynpro application.
Web service description:- This is a very simple application which takes two String inputs and when submitted displays the string in the concatenated form.
Web dynpro:- I used this web service in the web dynpro as an adaptive web service model.
The Layout design consists of two input fields which are mapped to the request fields
ex : - Request_Add.Add.S1 and Request_Add.Add.S2
A text area to display the response:- Request_Add.Response.AddResponse.Response
And a button which invokes the execute method
public void onActionWebserviceCall(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionWebserviceCall(ServerEvent)
    wdThis.wdGetWebserviceCompController().executeRequest_Add();
    //@@end
When I am trying to run the application I am getting error:-
Exception on execution of web service with WSDL URL 'http://<Host>:<Port>/EjbWebservice/Config1?wsdl' with operation 'add' in interface 'EjbWebserviceVi_Document'
Kindly reply.
Thanks
Neha

Hi,
Yes I have tested the web service in Navigator . The WSDL is also properly generated.
I have not publish the web service in UDDI but as per my understanding this is not necessary. please correct me if I am wrong.
Thanks

Problem while navigating the different portal Web Dynpro application

Hi .
while navigating from one application to another.
my IE browser stuck with the error.
Can't execute the code from the freed script.
it occurs:
when i navigate from tree structure 's child to another web dynpro application.
what to do ...
Regards

Hi John,
How have you added the required jar files. For DC projects you cannot use project properties and add the jar files to the build path (In case you have followed this method).
You will have to add the public part (i believe it is ejbclient.jar and is generated automatically when you create an EJB DC) of the EJB DC as used dc.

Error - Creating a Web Dynpro Application Accessing ABAP Functions

Dear All,
we are trying to implement a web dynpro application with accessing ABAP functions.
Previous tasks:
-     insert the ABAP system into the SLD from the NWDI System (Transaction RZ70; the ABAP system is correctly insert into the SLD => technical systems)
-     equipped the JCO connections with the web dynpro content manager (ping and test = OK)
Its the standard tutorial out of the SDN called Creating a Web Dynpro Application Accessing ABAP Functions.
Some hints:
-     There are no errors after the implementation and the rebuild of the project in the NWDS
-     The auto deployment works fine to the development runtime system. The application is shown in the Web Dynpro content manager
-     The In the build log I found these entries:

-     Im able to start the application out of the Web Dynpro content manager with run => only the user interface is displayed without any functionality
-     The normal start over the NWDS fails => error text
com.sap.tc.webdynpro.services.sal.core.DispatcherException: The requested deployable object 'local/J08_Flugdat_Daventdcflight~xxx.com' and application 'FlightListApp' are not deployed on the server. Please check the used URL for typos.
There two different URLs in use.
Start via NWDS:
http://frasapp562:50000/webdynpro/dispatcher/J08_Flugdat_Daventdcflight~xxx.com/FlightListApp
Start via web dynpro content manager:
http://frasapp562:50000/webdynpro/dispatcher/xxx.com/aventdc~flight/FlightListApp
For test purposes, we started the BAPI (BAPI_Flight_Getlist) on the ABAP system directly. It works.
Any ideas about the system behaviours (different URLs and missing functionality)?
Thanks a lot in advanced!
Best regards
Christoph

The Error has been solved The implementation of a method was missing....
Thx

Error while accesing ABAP web dynpro application

Hi Experts,
We are getting warning symbol on web page status bar, when we are accessing the ABAP web dynpro application
only first page of application is getting loaded and when we click on page it is showing error on status bar and we can perform any thing.
once we double click on warning icon,
below details are coming:
Line: 1491
Char: 3
Error: Object Expected
Code: 0
URL: url of the ABAP web dynpro application
This scenario is occuring for many ABAP WD application for a client.
Please guide how to solve this issue?
Thanks!
Piyush

Hi
First try a very simple application with nothing in it just one text saying Hello World
Run it and see what happens.
Also check if your url uses FQDN name. something like https:
company.name.co:50000\.......
If you do not use the FQDN it will always show a script error on the bottom and some functions will not work e.g
dropdowns.
regards
Yuval.
