Problem with Webdynpro

Hi Guys,
i am creating a new webdynpro but i have a small issue when i create the view in the layout is not showing the layout button screen, but is showing page cannot be displayed. can you pls help me in solving this issue.
thanks advance.

Hi Amit Kumar
For this you need to add the IP address and path in your hosts file
for this
go to C:Windows:/system32/drivers/etc/hosts and open the hosts file in a notepad
and add your server IP address and path
for eg: like this
10.10.30.89 ecc
or
if your server is a local system then your ip + path as
10.10.30.89 localhost.
after this restart your system, then the layout will open..
Cheers

Pls reward points if helpful.

Problem with WebDynpro using ReverseProxy

When calling a WebDynpro-Application through a ReverseProxy (mapping e.g. https://portal.intranet.company.ch to https://portal.ssl.company.ch) the first screen of the application can be called, but nothing happens when clicking on any of the controls/links or the message "500 Internal Server Error: The Web Dynpro Application 'xyz' has expired. Please restart the application either with the refresh button or click the following link xyz." appears.
Anybody has the same problems, any ideas why or how to solve it?

See OSS-Note <a href="https://service.sap.com/sap/support/notes/839969">https://service.sap.com/sap/support/notes/839969</a>
For EP6.0 you could use a Reverse Proxy Filter: <a href="https://service.sap.com/sap/support/notes/791080">https://service.sap.com/sap/support/notes/791080</a>
With NW04 all links in J2EE/Portal (inlcuding WD) should be relative and thus also WD should work through Reverse Proxies

Firefox 2.0 - Problems with Webdynpro and HTML iviews

Hello all,
We have implemented the SAP Netweaver portal 7.0 SP 10. Everything works fine on IE 6.0 and 7.0. When we tested it on Firefox 2.0, we encountered the following problems:
1. The links on the detailed navigation area are missing
2. Web Dynpro applications dont work very well. Eg: Clicking on "Next" button does not take you to the next view, OVS does not work etc.
3. SAP transaction iViews(HTML) don't show up at all.
Although the <a href="https://websmp108.sap-ag.de/~sapidb/011000358700001936242005E#391,7,SAP NetWeaver 7.0 (2004s) Browser Support For End Users and Admin Functionality">PAM</a> indicates that Firefox 2.0 is supported for Webdynpro and HTML iviews, I am not sure why this is happening. Can someone help?
Thanks and Regards,

Adobe are working on updating their add-on for Firefox 4 - http://kb2.adobe.com/cps/896/cpsid_89622.html
McAfee have released a version of the Site Advisor for Firefox 4, but this add-on has caused problems for some people such as not being able to permanently hide the add-ons bar and issues with the back button not consistently working.

Firefox 3..7 problems with webdynpro for abap

Hello,
webdynpro for abap is not running in firefox 3.7 alpha.
Is the problem known?
Regards
Oliver

That isn't even a final release level of the browser - so it of course woudn't be supported. Check the PAM (Product Availability Matrix) http://service.sap.com/pam for the latest supported browser versions. Often you need the latest support package in order to have correct rendering on newer versions of the browsers.

Problem with WebDynpro tutorial

Hello Folks,
i currently try out WebDynpro to get some experience with this technology.
I used the "Web Dynpro for ABAP: Tutorial 1- Create a simple Web Dynpro Application" and created a table display using this "context" stuff with reference to a table. Because I have not yet filled the sflight-tables i simply used T002T as a table (the language texts".
When I run my application in the browser I cant see any data. But the number of rows shown in the "scroll down" menu are exactly the number of rown in this table. I even restricted the selection of table further and then also have exactly the correct number of rows beeing displayed in the browser.
Having the correct number of rown is nice, but there is not data beeing displayed.
The 41 rows I selected and that are now displayed are simply empty.
Has anyone of you a clue what the reason could be? I think the binding is correct and the internal table is correctly filled by the method (because I can see the correct number of rows in the browser).
I usually prefer to find these errors by my own to learn but after 6 hours I thought that one of you might have the question or a good hint impromptu.
Regards, Hendrik

Hi Hendrik,
Are the column headers being displayed ?
If not that means you have only done the data source binding and not the column binding.
for this you need to right click on the table ui-element and say create binding, in the popup you select the node and its corresponding attributes, also select the cell editor ( u can go for textview ), next mark the binding 'checkbox' for each of the attributes, i think you would have missed out on this. Finally click on OK.
Activate and test.

Shweta

Authorization Problem with WebDynpro Services

Hi,
cam someone help me with this error:
No authorization to log on as a trusted system (Trusted RC=1)., error key: RFC_ERROR_SYSTEM_FAILURE
Thanks in advance,
Raj

This means that the user id that you have provided does not have the correct authorizations to log on to the system. You must provide that user id with the needed authorizations to proceed. I believe the authorization object is S_RFC. Give the rights for this and the problem should be resolved.

Problem with Webdynpro Tables and Scatter-chart

I have a Webservice who returns two one-dimensional arrays. I want to know how to fill one table with these arrays. And how to get this data displayed in an two dimensional scatter-chart as x and y Values.

Create a context node "Rows", cardinality 0:N, add attributes A, B (type as needed e.g. "string").
Fill the node with the content of your arrays array1, array2 (assuming both arrays have same length):
for (int j = 0; j < array1.length; ++j)
IRowElement row = wdContext.nodeRows().createRowsElement();
wdContext.nodeRows().addElement(row);
row.setA(array1[j]);
row.setB(array2[j]);
Display in a Table: Create a Table T, add columns CA / CB, add to each a TextView as cell editor. Bind cell editor's property "text" to attribute A / B.
For display in BusinessGraphics element, read the documentation at

FYI. Problem about webdynpro embedding

Dear Expert:
I encountered a problem with webdynpro embedded in portal.
Let's make it simple,
the source of a UI element Image in the webdynpro binds to a link   -> ftp://...../test.jpg
in my program I change the link dynamically after some action.
Everything works fine if I run this webdynpro.
But the strange thing is when I embed the webdynpro into portal, the image could not be displayed, even
it could not be shown if I bind it to the fixed link. (ftp:///)
I tried other source like http://///test.jpg, it works in portal,   but how FTP source fails?   I check there is no cache.
Thanks very much for your insight.

Please check your application log and/or default trace to see what exactly happened. It might have something to do with security (depending on your landscape between portal, Web AS, FTP site), how you generated the URL in your WD application. Please refer to this doc (p.18)

Problem with connector for ABAP Webdynpro

Hello,
I have a problem with a new Business Package :
Portal Runtime Error
An exception occurred while processing a request for :

Component Name : com.sap.portal.appintegrator.sap.WebDynpro
I think the problem is coming that I have no customized the connector with good values. Do you know a good blog or document to create a system alias dedicated to abap wedynpro or its bsp ?
Regards,

Yes, the UserId is the same in the portal and the BackEnd.
Previously we used the ITS for our ESS and now we are using the Portal, so all have an UserId and all personal have the same Id as before.
The first month it worked fine but when the password went out, in Back End, after 30 days, the question for login information appeared.

Problem with IWDTable in webDynpro

Hi,
I am using IWDTable ui element in my web dynpro application to display records, it works fine with IE-6 & IE-7, but in Mozilla firefox, if I click on the scroll buttons nothing happens.
I am using NWDS - 7.0.9, Mozilla - 2.0.0 & WAS - 6.40
How to resolve this error?
Thanks in advance.
Best regards,
Nilesh

Hi Nilesh,
there is number of issues with FireFox support and WebDynpro, so I suggest having a look at the SAP Support Portal and searching for known issues. I had various problems with the latest FireFox version (2.0.0.11) which were documented there - although no solution was provided.
Good luck!

Problem in Webdynpro and Adobe form with signature field

Hi experts!
I have a problem with Signature Field in Adobe Form showed in a Web Dynpro Abap.
During the execution I fill the Signature field correctly but when I push any other button of the Webdynpro, the Adobe Form shows me the next error.
After click OK, the webdynpro is hang and not respond.
Any idea why not respond?
Thanks.

Hi friend,
Its not like that the Adobe created using SFP is non interactive.
We can create interactive forms using SFP transaction using java code.
I think it will be the problem with ADS just check with your basis people i think they will configure you the settings which works fine.
To check whether the settings are perfect you can try executing the standard programs FP_TEST_00 and
FP_PDF_TEST_00. If it works fine then some other problem exists else check with your basis team.
Just check this and revert me if you have any issues. I will help you
Thanks,
Sri Hari

Problem with SLD and Creation of JCo

Hello everyone!
I have a problem with the SLD and the Creation of JCo on the Portal, in trying to create the JCo always tells me that the name used there in the SLD, being that the facility is new.
Who performs the installation, set in the SLD the ECC 6 PRD, delete it to see if I could create a JCo but still the error again when creating the ECC 6 PRD in the SLD I said that already exists and can not create it.
I found a forum which recommended re-import the cimsap .... .... zip and zip CR_Content which would clean everything, I managed to import the zip cimsap ... but in trying to raise CR_Content gives me the following message "All incremental updates of the selected aggregate import for export SAP_CR line have already been loaded before. You require a newer import to update your current content SAP_CR version 4.11." .
I recommend, do the installation again, reload the cimsap.zip and CR_Content.zip a copy homogeneous.
from already thank you very much

Hello!!
The "SLD" with which I am working up to Portal, the "ECC" installs itself as "ABAP.
Who did the installation and initial configuration, do not leave any documentation about it.
Now I need to create the systems and "JCo" necessary to enable them to implement the "ESS", but errors are presented above.
Some days ago I managed to update the CR_Content, which allowed me to create the "JCo" but at the time of the test, says' com.sap.mw.jco.JCO $ Exception: (103) RFC_ERROR_LOGON_FAILURE "name or password incorrect .
I managed to also create the portal systems, "System Administration -> System Configuration -> Content Portal" and to test it fails on "Test Connection with Connector", which as noted is associated with the connectors "JCo".
For the creation of the system, I think I should create something in the Visual Administrator ", but within the documentation that I do not see anything about it.
thanks for your help!

Problem with MultiLeadSelection in a table

Hi All,
I am still having the problem with the multilead selection in a table.
I am setting the table properties to multi and I have an event handler for the onaction property, named as leadselection.
I am writing the code below for the event handler.
public void onActionLeadSelect(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
int selectedRow = firstNode.nodeOPENITEMS_open().getLeadSelection();
    int sizeOfOpen = wdContext.nodeOPENITEMS_open().size();
     IOPENITEMS_openElement element = (IOPENITEMS_openElement)firstNode.nodeOPENITEMS_open().getElementAt(selectedRow);
     for(int i=0;i<wdContext.nodeOPENITEMS_open().size();i++){
          if(wdContext.nodeOPENITEMS_open().isMultiSelected(i)||selectedRow == i){
               wdContext.currentContextElement().setMultiDocNumber(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(selectedRow).getDOC_NO());
               wdContext.currentContextElement().setMultiItemno(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(selectedRow).getITEM());
               wdContext.currentContextElement().setMultiRepItem(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(selectedRow).getREP_ITEM());
               wdContext.currentContextElement().setMultiSubitem(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(selectedRow).getSUB_ITEM());
What i am trying to do is..On multiselection or on single leaad selection, I should pass the whole amount to the BAPI or the amount related to only the leadselection.
But when I am trying to run..this code..I am nt able to select in a multiple way..and more over if I press ctrl then I am able to make the other rows highlighted with orange color..but not normally and after making them highlighted also i am not able to pass the amount for all the selected rows..together..
Kindly suggest me..something..
Regards
DK

Hi,
Try this ,
for(int i=0;i<wdContext.nodeOPENITEMS_open().size();i++){
if(wdContext.nodeOPENITEMS_open().isMultiSelected(i)){
wdContext.currentContextElement().setMultiDocNumber(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i).getDOC_NO());
wdContext.currentContextElement().setMultiItemno(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i).getITEM());
wdContext.currentContextElement().setMultiRepItem(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i).getREP_ITEM());
wdContext.currentContextElement().setMultiSubitem(wdContext.nodeOPENITEMS_open().getOPENITEMS_openElementAt(i).getSUB_ITEM());
If you use the selectedRow variable in if condition, it will fetch only one row from table. Because the getLeadSelection() method gives the number of row which got selection on first click before pressing Ctrl key. So you can get only one value for leadselect. that's why the if loop failure for other selected rows.

karthik

Problem with breakpoints in Web Dynpro components

Hello experts,
I have problems with breakpoints in methods of Web Dynpro components. Sometimes everything works as expected and a new window with the debugger comes up. Sometimes the breakpoints are ignored, and debugging is impossible. It even happens that a colleague can debug and I can't or vice versa.
I am setting breakpoints with button "Set/Delete External Breakpoint", and the message always is "Breakpoint is set for user xxx". But sometimes when I display a method there is a warning that external debugging is not active. What does that mean and what is the reason for that?
As adviced in the SAP help document "Debugging Web Dynpro ABAP Applications" I have enabled the new Front-End Editor and the new debugger, but still the problem exists. Does anybody experience similar problems or have an explanation for this?
A second question concerns the different types of break points. My Web Dynpro component has an assistance class, and if I want to set a breakpoint there, I can choose between a session breakpoint and an external breakpoint. What exactly is the difference between these types? And here in the forum I sometimes read about internal breakpoints. Is this even a third type, or the same as session breakpoints?
Thanks, Karsten

Hi Kartsen.
External Breakpoint -> can be started from outside the SAP GUI (e.g. WebDynpro)
Session breakpoints are used if you start a programm or something like that in SAP GUI.
I have the same problem ... sometimes he does not recocnize a new break point ... so I just reload the page and the break point works.
If external debugging is not active, you habve to activate it in SE80 Utilities->External Breakpoints.
Also make sure that in your Settings the correct debugging user is set:
Utilities->Abap_Editor->Debugging.
Cheers,
Sascha

Thanks for your help
Best Regards

Hi,
May be you can put an external breakpoint in the method "_get_attribute_rtti"(of class CL_WDR_CONTEXT_NODE_INFO).
From that you can find out which attribute is causing the dump , and try to solve the issue . May be some data dictionary object is not transported to production.(Assuming that you have permission to put breakpoints in production system..:))
