How to display an error Message in Web Dynpro

Hello,
I want to display an error message in Web Dynpro. I'm using this,
IWDMessageManager message = wdComponentAPI.getMessageManager();
message.reportSuccess("<some relevant debug message>");
However, the message is always shown at the bottom of the screen. It is possible to select the location in the screen for showing this object? Or what is the best way for doing this? I've tried to use a Label but I can't set the type (warning, error, info) it's only a message.
Thanks
Regards
SU

Hi,
see the link here
[https://cw.sdn.sap.com/cw/docs/DOC-37733|https://cw.sdn.sap.com/cw/docs/DOC-37733].
as advised, you create a usage group for dynamic components, add component usages to the group based on your conditions.

Work on tasks without using the Web-Dynpro

Hello everybody,
i´m new at BPM and i have a question about tasks. Is there a way to work on tasks with the BPM API or something without using the Web-Dynpro? The System i work with is the CE 7.2. I can also use a CE 7.3 test System.
thanks
Edited by: jtrebess on Oct 5, 2011 3:57 PM

Here ist the scenario: I have to write an application which has its own UWL. I know that it is possible to read tasks for the current user. Is it also possible to manage the task with the BPM-API? Is it possible to get the output parameter and to transfer the required Input parameter?

UI-Type using the Web Dynpro Dode Wizard

Hi,
every time i use the Web Dynpro Code Wizard and choose the Form i still get the UI-Element-Type "InputField". Is it possible to select ohter Element-Types for example DropDownByIndex or Text_Edit?
i hope we can fix this.
best regards,
Michael

Ofcourse you ca change it to UI-type that you want.
change the Standard Cell Editor to DropDownbyKey all the UI elements will change(Default it will be InputField because most of the forms contains more number of InputFields ), also you can change the individual context attribute UI type also by changing the CellEditor of a table Column.

First,I created a Web dynpro DC,and make the component to public .
Then,I created another Web dynpro DC,Add the first DC in Used DCs,But in this Web dynpro, I can't use first Web dynpro Method,can anyone tell me how to do it?

Go for below document.

What is the right way to display a table in Java web dynpro using a node.

Hi experts,
I am trying to show a node of cardinality 0...n as a table in an adobe form in Java web dynpro. But its not showing it properly. Can anybody please tell me what is the right way to display a table on adobe form using a node of cardinality 0...n or 1...n in Java Webdynpro. In ABAP webdynpro, we can drag and drop a node of cardianlity 0...n or 1...n to show as a table and it works fine. Is the same possible in Java webdynpro also. Please help.
Thanks and Regards.
Vaibhav Tiwari.

Please refer to my post.. you will get the answer
Dynamic Table - same data repeating in all rows
Special care should be taken in designing the context for table attribute.
The attribute type singletone also plays a important role. I have this doubt from the beginning when you have reported this problem for the first time but finally you marked it as solved so i thought there might be some other issues but again when you reported that again i did some analysis.
Now coming to final solution :
For designing a table in adobe interactive form you have consider following
You have to design the view context upto three level, I am explaining you the properties
PDFDataSource (Parent Level1) - Cardinality 1:1 - Signetone -True - This is assigned to datasource
TableList (Parent Level2) - Cardinality (1:1) - Signetone -True
TableWrapper(Parent Level3) - Cardinality (0:n) - Signetone -True
TableData (Parent Level4) - Cardinality (0:1) - Signetone - false (This is the main point)
Then under TableData value node, you have to put all your table attributes.
This Value Node name can be anything but hierarchy should be same as I have mentioned above.
Please try out these steps and get back to me if you have any doubt.

Load and Display Multiple Images in a Web Dynpro Table

I am new to Web Dynpro and I am wondering if anyone can help me with an application that I am currently developing. I have a particular requirement to store images in a database table (not MIME repository) and then display them in a WD table element. An image can be of JPEG, PNG or TIFF format and is associated with an employee record.
I want to create a view in my application that displays multiple images in a table, one image per row. I want to do this using Web Dynpro for ABAP, not Java. I have looked into pretty much all examples available for Web Dynpro and came to the conclusion that Components such as WDR_TEST_EVENTS and WDR_TEST_UI_ELEMENTS do not have any examples of images being stored in a database table and viewed in/from a Web Dynpro table element. Programs such as RSDEMO_PICTURE_CONTROL, DEMO_PICTURE_CONTROL and SAP_PICTURE_DEMO do not show this either.
The images to be displayed in the Dynpro table are to come from a z-type table, stored in a column of data type XSTRING (RAW STRING). So I would also like to know how to upload these images into this z-type table using ABAP code (not Java).
Your help would be greatly appreciated.

Problem with Table display in Adobe Form of Web Dynpro ABAP

Hi Team,
I'm trying to display a table in Adobe Print Form (not interactive). The table is bound to the context node in the Web Dynpro ABAP where the cardinality is 0:N. I get a short dump. Don't know what to do here. I'm able to display individual fields from my context successfully. Looks like something is missing when I try to display a table. Any pointers to display a data table in Adobe? Any step by step example you know of where I can find out what I did wrong? Many thanks for your time
We are on support pack SP06 on 2004S release.
DUMP INFORMATION:
Short text
    Access via 'NULL' object reference not possible.
What happened?
    Error in the ABAP Application Program The current ABAP program "CL_WD_ADOBE_SERVICES==========CP" had to be terminated because it has come across a statement that unfortunately cannot be executed.
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not caught in procedure "CREATE_PDF" "(METHOD)", nor was it propagated by a RAISING clause.

Hi Thomas,
We upgraded our system(2004S) to SP10 so that we can use the ADOBE form printing in Web Dynpro ABAP but could not apply note 1034425 because of the validity constraints in SNOTE. All the pre-requisite notes are already in the system apart from one note 1029721 which talks about supporting input helps. We don't want to use input helps in our system and cannot upgrade to SP11 because of problems with Business functionality.
Questions:
1) Is note 1034425 absolutely dependent on 1029721?
2) If NOT, can someone please correct the validity so that we can implement using SNOTE.
3) Would it be OK if we manually apply the changes specified in 1034425 without implementing 1029721?
4) If all of the above is not applicable, is there any other note which fixes the above mentioned short dump.
Your help in this matter will greatly help us in using the ADOBE services provided by SAP WDA.
Thanks much

No. There is no container for displaying SAPGUI inside of Web Dynpro. The closest you could get to this would be the SAPGUI for HTML running inside an iFrame, but that is completely different than what you are talking about (and also not recommended). Dynpro/SAPGUI output is a very different technology thatn Web Dynpro and the two can't be mixed directly. You need to find a way to extract the data you need without any calls to visualize it.

Displaying KM Property structure in Web Dynpro

Hi All,
From SAP Help:
<...>
A property structure displays properties of a resource (folder, document, or link) in a fixed order.
A property structure can be displayed in the following places in the system:
· In the Details dialog box for a document or folder under Settings ® Properties.
· When creating or editing a document or folder, using the link Show Properties.
<...>
How to proceed when I want the property structure to be displayed as a Web Dynpro.
Do we have to build a "WebDynpro-PropertyStructureRenderer" or are there short-cuts possible??
Kind regards,
Maarten

Hi Maarten,
There are commands to allow you to open the Details page to the Properties page.
See the UI commands called "details_properties" and "details_properties_ex"
These generate links directly to that page for a resource. You can see similar
examples of how these are formulated using the "Status Explorer" Layout set.
You can do this by opening a KM iView in a new window and adding
"&rndLayoutSet=ConsumerTreeStatusList" to the end of the URL.
The parameters allow opening the page with or without the rest of the details page
navigation. The effective parameters will look something like this (for permissions,
but properties is similar):
&Standalone=true&command=permissions&isp=permissions&StartUri=/documents&StartPage=StandaloneDetailsPage
You would have to generate the corresponding URL in WD.
Regards,
Darin

Find keyword used in Web Dynpro Application?

Hi folks,
I have a simple question with regards to Web Dynpro for ABAP: Is it possible to search in my application for a keyword that I have used?
For e.g., I wish to search for the keyword "loop" to find out which parts of my program have this matching string. I have many views, windows, and code in my component controllers.
Is that possible? Please advise. Thanks in advance.

Read this thread:
how to view COMPONENTCONTROLLER interface 's implement class
With my approach you can access the generated class and search on it globally from SE24 (efectively searching across the whole component).
With Thomas approach you can only search on controller by controller basis but may be a bit less complicated to use.
