Hi Gurprit,
A null value is being passed at runtime. Make sure that you enter values when filling in the form.
Also check for the cardinality of the nodes being used. You can also initiliaze your value attributes as follows:
In wdDoInit() method:
wdContext.currentNodeAElement.setValueA("");
Context is as follows:
RootNode
|____NodeA
|_____ValueA
Hope it helps.

Replicate ME52N create attachment and attachment list in Web dynpro

Dear Experts,
Please can someone provide sample code and 'How to' steps to replicate ME52N create attachment and attachment list in Web dynpro?
I've looked at FILEUPLOAD and FILEDOWNLOAD in Web dynpro and this seems suitable for only 1 file attachment.
Many thanks, Jas.

Hi ,
If your are having a UI like ME52N and you want an attachment feature in each row, I have below suggestions:
Suggestion 1: If you use ALV
Add a column in list of type Xstring or which ever suits your document specificatio
Add a Button on the ALV for attachment,
On click of the button you can Popup a browse window and user can select the file.
The content of the file can be stored as Xstring for that Line item.
Suggestion 2: IF you use Table UI element
Add an attreibute to context node of type Xstring
In the Table set, you can set FIleUpload as the editor for this column.
I hope it helps.

Sumit

How to view online and offline assets

I have to delete a page from clients website. I'm in CC and when I go to manage sites, I no longer see the server on the left and the HD on the right. How do I get my assets to display the way I need to work? I've googled, gone to help and I'm not really seeing an answer. Thx.

If you are looking for an option to view remote and local view of the site in same window, you need to expand the files panel. It's not in Manage sites.
Have a look here http://help.adobe.com/en_US/dreamweaver/cs/using/WSc78c5058ca073340dcda9110b1f693f21-7ed0a .html

How to create table in interactive form via Java Web Dynpro

Hi,
How to create table in interactive form via Java Web Dynpro ?
Any online tutorial / example ?
Thank you.
Regards,
Eric

Hi Eric,
Just choose the UI element Table from Form Library and drag and drop it on the form. now choose the no. of rows and columns and other settings you want about table from the wizard initiated through this process. This all is what you have to do to create the table. Now to bind it to the fields of the data source bind the individual colums to individual attributes of the node in the datasource.
Hope it will solve your query.

How to create parent and chile process in java

i'm beginning in java, and i want to ask something, please help me...
1. i want to ask how to create parent and child process in java???
example :
if have one window and explore menu, when i click the explore menu.
new window come out.
how if i close the parent window the child window will close too...
2. what is the method from runtime class to get available memory and Active Threads count

ONE way to do what you wanted is this.
class Parent{
Child c = new Child
allChildren.add(c);
//if close
iterate through list
(Child)allChildren.get(index).close();
ArrayList allChildren;
class Child{
public void close(){ }
i dont know if you can get the thread count. but you can
get the current thread by using System.
Memory: Runtime.freeMemory() .maxMemory() .totalMemory()
http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html
Careful though you have to do a calculation to get the
actual memory because those 3 methods refer to freeMemory
of the CURRENT heap not the total memory.
i think its: total - (max - free)

How to create table and digital signature ?

Hello,
I would like to ask two questions regarding SAP interactive forms by adobe.
1st question:
How to create table in interactive form?
Table that i can add rows and column and will show it in the form.
Example the rows and columns that i want:
ID: Name: DOB:
1 Jack 01/02/80
2 Ivy 10/12/82
2nd question:
How to create digital signature ?
I'm creating a adobe forms which need employee to sign on the form. I use signature field at my form. However, i don't know how to create a new signature and insert in the signature field.
Can any one provide the answer with step by step guide?
Thanks a lot

Hi Pradeepa,
you said you have your digital signature in
BMP format? That means Bitmap and would mean you are actually talking about a picture! THIS IS NOT A DIGITAL SIGNATURE!
A digital signature is a cryptographic key (aka public key cryptography) that is used to digitally sign a document, or at least a hash value derived from the document. Digitally signing means, applying the key in a well defined way (this is the algorithm used) to the document or hash value. You do this with your private key and the receiver of the document can then use your public key (which you can distribute in any way you want, even unsecure) to unencrypt the hash value. If this succeeds the receiver knows that the document was signed by you.
This is because both keys are mathematically related in such a way, that what one key encrypted can only be decrypted by the corresponding other key and by no other key. You even can´t decrypt a document with the same key it was encrypted with, this is the difference to symmetric encryption - please have a look at help.sap.com and search for digital signatures.
The named formats (afs, pfx and p12) are ways of coding the key, together with information about your person, such as email address and information about validity of the key into a
certificate. This type of certificate is then called a x.509 certificate and is the same you might have seen when connecting to a secure webserver such as the one of your bank website.
Signing a form with such a certificate provides for mathematically and therefore business related proove of a users identity.
In case you are really using a bitmap, this cannot work and would not serve you any good.
Ask yourself this question: I want to make sure that the form was signed by a specific person. How can I make sure that the signing can only be done by the person pretending to have done so?
A bitmap contains a picture, probably of the persons handwritten signature. How can I make sure that this picture was NOT recreated in MS Paint or Photoshop by someone else?
The answer is:
you can't! Therefore this way of prooving identity is useless.
You need to provide your users with digital signatures, put these in the certificate cache of your IE. If a user then clicks on the signing field, the private key is used to digitally sign the form - create a hash value of the form and encrypt it with the private key. After the form is send back to the server or you, you use the corresponding public key to decrypt the hash value and, as said above, if this succeeds, identity of the signer is proven.
THIS IS AN OVERSIMPLIFICATION! You might want to take a look at Adobe Reader Credentials.

 Christian

How to create Parent and Children is a tree table / trigger sequence number

How to create Parent and Children is a tree table when the primary key of the parent is generated via a trigger and a sequence number in the database?
My problem is when I create a parent and then right away a children. The parent still not have a primary key until the transaction get to the database. I get a error when trying the create the children, cannot insert null in the foreign key field of the children.
Please help.
Stephane

You should have the parent key be marked as a DBSequence type.
Then you should have the association between the master and detail defined as composite association to make sure that the posting order to the database is correct.

Here you go..Just follow these steps blindly and you are done.
1) Create a year prompt with presentation variable as pv_year
2) Create a report say Mid report with year column selected 3 times
- Put a filter of pv_year presentation variable on first year column with a default value say @{pv_year}{2008}
- Rename the second time column say YEAR+1 and change the fx to CAST(TIME_DIM."YEAR" AS INT)+1
- Rename the second time column say YEAR-1 and change the fx to CAST(TIME_DIM."YEAR" AS INT)-1
Now when you will run Mid Report, this will give you a records with value as 2008 2009 2007
3) Create your main report with criteria as Year and Measure col
- Change the fx for year column as CAST(TIME_DIM."YEAR" AS INT)
- Now put a filter on year column with Filter based on results of another request and select these:
Relationship = greater than or equal to any
Saved Request = Browse Mid Report
Use values in Column = YEAR-1
- Again,put a filter on year column with Filter based on results of another request and select these:
Relationship = less than or equal to any
Saved Request = Browse Mid Report (incase it doesn't allow you to select then select any other request first and then select Mid Report)
Use values in Column = YEAR+1
This will select Year > = 2007 AND Year < = 2009. Hence the results will be for year 2007,2008,2009
This will 100% work...

How to implement XI interfaces in online and offline modes?

Hi Everybody,
Can you please tell me how to implement XI interfaces in online and offline modes?
thanks a lot,
Ramya Shenoy.

Hi,
Are you looking for Push and Pull mechanism of PI?
When the adapters like SOAP, HTTP, IDOC, etc. send the data to PI , it is nothing but a push mechanism, and hence the communication is synchronous by default.
But adapters like JDBC, File, etc. they fetch the data from Source Applications, so it is a kind of Pull mechanism for PI, and
by default communication is asynchrnous.
Pls elaborate exactly what are you looking for?
