Thanks,
sathya.

Hi,
This is because their is no elements in the node which is bound to the table.
Following are some of the ways to make it editable.
1) Make the cardinality of the node boubd to the table as 1..n , So that atleast the first row is editable when the screen is launched.
2) Create an element of the node either in the init or create a button called add row and code as follows
wdContext.node<YourNodeName>.createAndAddElement();

Currency Key Reference field in WebDynpro Table Column

Hi Experts,
I am using a WebDynpro table (not ALV) showing multiple currency fields in a single row - each one potentially referencing a different currency key e.g. Japanese Yen and USD in a single row.
My currency context attributes are already defined as currency types, but how can I assign different currency key references to each of my currency context attributes? Or is this somehow done as a property of the table column UI element?
Thanks for your help,
Peter

Hi Kris,
You answer is very helpful, but I do have a question about going the DDIC route. So you are saying that if I take a DDIC structure into my context with multiple currency keys as reference fields for multiple currency fields, then my WebDynpro context will know exactly which currency key is the reference for which currency field without having do do this programatically as you described? If that's true, can I bring a whole DDIC structure over to the context and then delete the 'Dictionary Structure' refrence from my context node, so that I can add my own additional fields to the context node? E.g. in the case of DDIC structure VBAP can I get all my currency fields and their reference fields from the DDIC from VBAP and then delete 'VBAP' as a 'Dictionary Structure' from my context node and add my own custom fields. The fields I would have brought in from VBAP still retain their type and everything after the deletion of 'VBAP' as a 'Dictionary Structure', so my question is will it also retain the node_info of what currency key goes with what field?
Please let me know if you happend to have done this before.
Thanks,
Peter

Oracle - Webdynpro Tables

hi experts,
How to Store and fetch the data from oracle BD and after fetching i want to display that result in webdynpro table and storing is also from webdynpro view interface.
can anybody help me on end to end procdure how can i achive.
Advance Thank you,
vijai

Hi vijay,
<b> using EJB and connect with oracle.</b>
the step by step procedure is follow how to connect with oracle
1) Open the J2EE perspective
2) Create an EJB Module project
3) Right click on ejbModule, create a new EJB (select your EJB type)
4) While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5) Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6) Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7) Create an Enterprise Application project.
8) Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9) Right click on the EJB project, select Build EJB Archive
10) Right click on the EAR project, select Build Application Archive
11) Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
Java Build path - select the EJB project from projects , check the selected project under Order & Export
Project references select the EAR project
WebDynpro references select sharing references tab, click add & make an entry as : <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12) Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
MyEJB mybean = home.create();
int a = 0;
a= mybean.add(10,15);
wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
i hope that the above steps are useful for u.

Workbook w=Workbook.getWorkbook(f);
Sheet sh=w.getSheet(0);
int cols=sh.getColumns();
int rows=sh.getRows();
Cell c=null;
String s1=null;
String s2=null;
String s3=null;
String s4=null;
ArrayList al=new ArrayList();
int j=0;
for(int i=1;i<rows;i++)
ITableElement table=wdContext.createTableElementz
     s1=sh.getCell(0,i).getContents();
     s2=sh.getCell(1,i).getContents();
     s3=sh.getCell(2,i).getContents();
     s4=sh.getCell(3,i).getContents();
                         table.setName(s1);
     table.setAddress(s2);
     table.setDesignation(s3);
     table.setDummy(s4);
     al.add(j,table);
     j++;
wdContext.nodeTable().bind(al);

How to make 2 lines in a webdynpro table cell?

Hi
Is it possiable to create a WebDynpro Table Call that can contains 2 lines in 1 cell ?

Hi Ami,
There are a limited number of UI elements that you may use for a Table Cell Editor, however, with a TextView, you can display text that includes a line break.
The line break is achieved by including the carriage-return-line-feed characters in the Table's data source...
LOOP AT lt_flight_tab ASSIGNING <f>.
CONCATENATE 'Line One' cl_abap_char_utilities=>cr_lf 'Line Two' INTO <f>-test.
ENDLOOP.
Cheers,
Amy

Webdynpro table with dropdow list

hi experts,
i wanna webdynpro table rows have their dropdow list,and each row have it's own list values
how can i do
best regards
zlf

Hi,
I hope you already have a Solution, if not try the following:
1-Create a node"table"(0-n) in the context_View
2-Create 2 attribute in this node.
- The first"List_atr" to show the list
- The second "save_atr" to save the value selected from the list
3- Create a Table in the Layout_View, bind it dateSource to the node"table" in context_view
3.1- Add a Column in the Table (Layout_View),
     + add a TableCelEditor "DropDownByKey" elt to this Column,
     + bind the "selectedKey" of this Elt to the first"List_atr" in the node"table" in the context Node
     + Add a eventhandler(method)"onvalSelected" to the Events "onSelect" of this elt
3.1-implement the method "onvalSelected"
    here tel ur view ctrl to save the value selected in the second "save_atr" in the context_View
example code:
           wdContext.currentTableElement().setsave_atr( wdContext.currentTableElement().getshow_atr());
So if you know how to populate the first "show_atr" with some list, coo. So if the user selected one value in the dropdown list, the method will save it in the cell of the table row and so on for each rows.
If you have another questions just asked.
Best Regards

bindu

Hi, I solved the same problem by modifying the sort() method in the default TableSorter class so that it takes a column id and direction rather than an event.
I assume you have read the TableSorter tutorial.
Like this. (This was done on nw ce 7.1 btw but may work on older versions as well.
Oh and then you just call the sort method right after you have made the request
//Code that goes into controller/view to execute sorting
wdContext.currentContextElement().getPensionplanTableSorter().sort("MyColumnId", "Up", wdContext.nodePensionPlan());
//Part of TableSorter.java
//The original method that needs an event. Now it just calls the new method
public void sort(IWDCustomEvent wdEvent, IWDNode dataSource) {
     // find the things we need
     String columnId = wdEvent.getString("selectedColumn");
     String direction = wdEvent.getString("sortDirection");
     sort(columnId, direction, dataSource);
//This is the new method.
public void sort(String columnId, String direction, IWDNode dataSource) {
     if (columnId == null || direction == null ) {
          return;
     IWDTableColumn column = (IWDTableColumn) table.getView().getElement(columnId);
     NodeElementByAttributeComparator elementComparator =
(NodeElementByAttributeComparator) comparatorForColumn.get(column);
     if (elementComparator == null){
     //not a sortable column
          column.setSortState(WDTableColumnSortDirection.NOT_SORTABLE);
          return;
     // sorting
     elementComparator.setSortDirection(WDTableColumnSortDirection.valueOf(direction));
     dataSource.sortElements(elementComparator);

WebDynpro 中Table的column的换行.

dear all.
WebDynpro 中Table的column的长度太长了,有没有换行属性?
Edited by: Leo Wang on Jan 19, 2009 7:31 AM

首先要把Table的width属性设备成一个定值，或者将TableColumn的width属性设成一个定值，然后再将Column中的TableCellEditor设成TextView，然后再将TextView的wrapping属性设成true，当TextView中的文本长度超过了Column的长度后，TextView就会自动换行，这样就可以达到换行的目的了。

RFC data into WebDynpro Table based on Page selected by user in Portal

Hi All
I am new to webdynpro. we are developing an application in which we are supposed sent two parameters to RFC to retrive data. Two parameters are Role (plant) and page names(Sub - plant).
Finally there should only one RFC for whole application which takes parameters when user selects a role and page inside a role.
How can I do this. Please help me.

Hi,
1. Develop an RFC at the backend SAP system, which takes in 2 input ( plant and sub-plant) and gives the list of results as a table.
2. Create a model in the WD Java application to call the RFC.
3. call the rfc, get the output and print the result in a table designed in the view.
There is a sample application which can be found here
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/wd%20java/wd%20tutorials/creating%20a%20web%20dynpro%20application%20accessing%20abap%20functions.pdf
This does a similar application which you are trying to do. This takes in 2 input parameters from the user 'Departure city' and 'Arrival city' and prints the list if flights. If you go thru this sample application, you can develop urs very easily.
You can even get the source code of this project in the following link
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/webcontent/uuid/28113de9-0601-0010-71a3-c87806865f26?rid=/library/uuid/49f2ea90-0201-0010-ce8e-de18b94aee2d#15 [original link is broken]

WebDynpro, Table, selected rows, multiselect

Hi together,
I've got a problem with my "table-control" in WebDynpro.
I just want to read the selected rows in the tablecontrol.
To read one row is no problem:
wdContext.currentnode.....
But if there are more selected rows I don't know how to handle. Could I use the Context-Node, or do I have read the Table-Control-Attributes ? And how ?
Please help me.
Thx a lot.
Greetings
sb

You have to look at the selection of the context node used as table data source. The selected elements are given by
node.getCurrentElement() -> the lead selected element
node.isMultiSelected(i) -> if element at index i is part of multiselection.
