Hi,

Suppose the values is not there(null) and ur checking some conditions based on this value.
Null pointer exception will araise due to any nullvalue.
To avoid this plz put the check--> if(!value = null){........ }.

I have cross checked the models and found that the Model is there in the model types.
Can any one help me regarding this.
Waiting for the response ASAP.
Thanks

Hi,
I think you mean ear file and not par file. Check these threads. The exception is mentioned to be because of JCo problems only.

I have seen this funny error message crop up time and again. Though only for particulaer set of users only.
When developing cuetom applications you will have to do register the BLC compeonent as mentioned in the documentation below. If you dont register you are sure to get this error
http://help.sap.com/erp2005_ehp_04/helpdata/en/43/42b7eb8eba2a21e10000000a422035/content.htm
You should not get this error for standard applications as the BLC is always registerd as mentioned in the above documentaion
But when ever I got this error for standard applications, restarting the browser of the end users or in extreme cases the portal server resolved this issue. Fortunately I never got this error in production

Hi Puneet,
I am getting same exception in using FileDownload UI element as a Table Cell Editor.
I am loading input stream in FileDownload UI element on demand (that when user actually clicks on download link)
Can you please share what exact optimization you did in code and it worked for you?
Please help me with this issue.
Awaiting for your reply.

FPN error: com.sap.tc.webdynpro.services.exceptions.WDRuntimeException

Hi, all.
I am trying to initiate a webdynpro page from the producer to the consume portal via RDL. It works fine for a day. Then it starts giving me the error:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to load page ...
This error cannot be cleared by clearning the FPN cache or synchronize with the producer. Of course, you can also delete the page from the consumer and copy it over from the producer again. It will work. But this is not a good workaround for a production system. We also don't know the cause either. Here is the stack trace:

So far I found nothing on OSS or SDN on this FpnUnMarshallingException. Has anyone seen this error before?
Thanks.

Hi Jonathan,
you may deactivate the GPN cache as well as the old navigation cache. About the GPN there is note 1172433. Both caches are not used in FPN scenario and can lead to such strange problems. If this won't help please open a support message for this that we can analyse further.
Cheers,
Anja

I searched the forum but could not get a solution though mnay have faced this problem. This is for all applications and not only PCR.

Cannot access WebDynpro application:com.sap.tc.webdynpro.services.exception

Hello gurus!!
I am trying to access the "Emergency address" from the LWE and I am getting this error "Cannot access Web Dynpro application: com.sap.tc.webdynpro.services.exceptions.WDException$DummyLocalizableTextFormatter@76829226". Could anybody please suggest what could be wrong with this action "Emergency Address"?
Thanks much for your help with this,
Maria Kutty Somori....

Hi Yugandhar/Siddharth,
Emergency address is the standard callable object for Execution that is part of the Standard Life and Work events. I have customized to reorganize the actions depending on our requirements and i have created a different folder structure and different order of execution of callable objects.
How do I fix this "cannot access Webdynpro application" error? Please suggest.
Thank you so much,
Maria Kutty Somori.....

To explain further, I have 3 views in my webdynpro project, list view, results view and detail view that is embedded in the same window.
In the list view, I have a table of materials with linktoaction event that when clicked will go to detail material view to display material information. In this scenario this is working with no problems for all the items in the list.
When I do the same thing from the result view as the list view, only the first url link action works to display the detail view , the others fail with the above exception.
Any help on resolving this issue is appreciated.
Thanks,
Sunitha.

Ayyapparaj,
The lifespan of ResultsView is "FrameworkControlled".
Following is the code snippet for onclick of a row in the table in the results view,
     IWDMessageManager messageMgr =     wdThis.wdGetAPI().getComponent().getMessageManager();
//     getting the user's assigned SoldTo from the UME profile
      String[] customer = null;
      String SoldTo = null;
      try
                IUser user = WDClientUser.getLoggedInClientUser().getSAPUser();
                IUserAccount[] acct = user.getUserAccounts();
                customer = user.getAttribute(AvailabilityApp.NAMESPACE_LENNOX,AvailabilityApp.ATTR_SOLDTO);
                SoldTo = customer[0];
           } catch (UMException e)
                     // TODO Auto-generated catch block
                     messageMgr.reportException(e.getMessage(),false);
     //create the instance and pass parameters for RFC Z_RFC_HRP_MATERIAL_INFO_Input
     Z_Rfc_Hrp_Material_Info_Input input = new Z_Rfc_Hrp_Material_Info_Input();
     wdContext.nodeZ_Rfc_Hrp_Material_Info_Input().bind(input);
    input.setMatnr(wdContext.currentATP_To_AtpElement().getMatnr().toUpperCase());
    input.setUser_Id(SoldTo);
     //executing the RFC Z_Rfc_Wwhc_Zatp
     wdThis.wdGetAvailabilityAppController().ExecuteZ_RFC_HRP_MATERIAL_INFO();
     wdContext.currentContextElement().setReturnTextDisplay("Availability Results");
     wdThis.wdFirePlugToDetailView();
When it goes to Detail view and try to display the UI bound to the output from the above
Z_RFC_HRP_MATERIAL_INFO() , it shows this error.
Please note that the above code does not fail for the first row of the results table in the results view, but it does for all the others. Is there something that I am missing here ?
Thanks,
Sunitha.

Length of com.sap.ide.webdynpro.uielementdefinitions.Resource

Hi Experts,
I've used the FileUpload control in a WebDynpro page. I'm using the CE 7.1 version of NWDS.
This control has a Type property which I've bound to the following Simple Type:
com.sap.ide.webdynpro.uielementdefinitions.Resource
The default length of this type is 255 (binary).
When I try to upload a text file with the following name:
"111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111111.txt"
it shows blank in the file upload text field. Perhaps this is because I've tried to upload a file with a maximum name length which Windows XP OS allows. This is much larger than the 255 length limit of the built-in simple type.
Can anyone suggest me a workaround to bypass this limit on the length of the file name.
Regards,
Nitin

Hello,
Once you upload a file it gets stored in your controller context in binary format....0010100101011010....
Now from this context you can either reuse the content in current aplication at runtime...or you can later save this file on server.
But once upload is done...its only there in your controller context.
You first need to define a context attribute of type com.sap.ide.webdynpro.uielementdefinitons.Resource. The Resource type is a special dictionary simple type for MIME resources. At runtime the controller context attribute stores the MIME resource in an object of type com.sap.tc.webdynpro.services.sal.datatransport.api.IWDResource.
Hope you have properly referred to below article.
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/00062266-3aa9-2910-d485-f1088c3a4d71?quicklink=index&overridelayout=true

Java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/clientserver/uielib/st

Hi everybody,
I got trouble with my WebDynpro Application. When I deploy an application including a Table without being bound to any context node, the deployment works and the view is rendered properly. As soon as I bind this table to the context in order to fill the columns, I receive the Exception Message in the subject line. I tried running this application on several WEB AS Version from SP 14 to 17, however, I received the same Exception everytime. Is the framework of my NWDS broken or what is going on?
I'm grateful for every hint that could solve the issue,
thx and rgds,
Otto

Hi Sri,
Might it be the case that you have a component with the same names in some other DC which is also deployed on the server. Web Dynpro does not allow this (as stated in the message below).
Thus you could use the "Deployment Perspective" to undeploy the other DC before deploying the new one.
Cheers,
Martin
