Hi,
See, if you bind only one attribute to the readonly then the entire column would be readonly or editable. I can think of two ways to solve this problem.
1. Add a new attribute to your node like _readonly
Bind this _readonly to the celleditor readonly property of the table coulmn.
You can fill this attribute either in the back end per row or loop through the node in the webdynpro and by default set it false. Enable true based on your condition.
2.Bind the attribute property read_only to the cell_editor readonly property of the table column.
Based on your condition use the if_wd_context_element method set_attribute_property to set read_only property true or false.

How to use EVS with different data in each row, in a Java Web Dynpro table?

Hi all,
I am using EVS in a column of java web dynpro table.
Let's say the name, and context attribute, of this column is column1.
It's filled dynamically using an RFC, that uses as input parameter the value of another column, and related context attribute, from the same table (Let's call it column2). Obviously, from the same row. So, in other words: the values of the EVS in column1 of row1, are dependent of the value of column2 of row1. And the values of the EVS in column1 of row2, are dependent of the value of column2 of row2. And so on... Hope i could explain myself ok.
The code I'm using works great for filling the EVS dynamically:
IWDAttributeInfo attrInfo = wdContext.nodeDetail().getNodeInfo().getAttribute(nodeElement.COLUMN1);
ISimpleTypeModifiable siType = attrInfo.getModifiableSimpleType();
IModifiableSimpleValueSet<String> value = siType.getSVServices().getModifiableSimpleValueSet();
value.clear();
if(this.initRFC_Input(nodeElement.getColumn2())){
     for (int i = 0; i < wdContext.nodeRFCresult().size(); i++){
          value.put(wdContext.nodeRFCresult().getRFCresultElementAt(i).getLgort()
             , wdContext.nodeRFCresult().getRFCresultElementAt(i).getLgobe());
In this code, nodeElement is the context row of the table that is passed dynamically to the method when the value of colum2 is changed.
HOWEVER, the problem I'm having is that after executing this code, EACH NEW ROW that is added to the table has by default the same values as the first row, in the column1 EVS. And, for example, if I refresh the values of the column1 EVS in row 2, all EVS values in the other rows are also refreshed with the same values as the ones of EVS in row 2.
How can I make sure each row EVS has its own set of independent values, so they don't mess with each other?
Hope you guys can help me. And please, let me know if I didn't explain myself correctly!
Thanks!

I just did as you said (I think), but it's still having the same behaviour as before (same data for all EVS in the table).
Here´s what I did:
I
In node "Detail" (cardinality 0...n, singleton set to true), which is binded to the table, I created a child node named "Column1Values" wth cardinality 1...1 and singleton set to false.
"Column1Values" node has an attribute called "column1", of type String.
I did the binding between attribute "column1" and the column1 inputfield celleditor in the table.
I created an event called Column2Changed and binded it to the column2 celleditor of the table. I added a parameter called nodeElement of type IPrivateCompView.IDetailElement to this event, and mapped it to the column2 editor in the table so that I can dynamically get the nodeElement that is being affected.
I added the following code to the onActionColumn2Changed(wdEvent, nodeElement) method that gets created in the view:
IWDAttributeInfo attrInfo = nodeElement.nodeColumn1Values().getNodeInfo().getAttribute("column1");
ISimpleTypeModifiable siType = attrInfo.getModifiableSimpleType();
IModifiableSimpleValueSet<String> value = siType.getSVServices().getModifiableSimpleValueSet();
if(this.initRFC_Input(nodeElement.getColumn2())){
     for(int i =0; i < wdContext.nodeRFCresults().size(); i++){
          value.put(wdContext.nodeRFCresults().getRFCresultsElementAt(i).getId(),
                              wdContext.nodeRFCresults().getRFCresultsElementAt(i).getDesc());
And with this, I still get the original problem... When the EVS of one row is updated, ALL other EVS of the table get also updated with the same values.
What am I missing? Sorry Govardan, I bet I'm not seeing something really obvious... hopefully you can point me in the right direction.
Thanks!

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.

Integration of a Tree Structure in a Web Dynpro Table

Hi,
I am implementing an Integration of a Tree Structure in a Web Dynpro Table.
The Tree-Table os working as required, but I can not work with the OnLeadSelect Action of the table.
The Action does not work as required, meanning, it returns all the time the first row and not the "lead select".
As far as I read I should add some code to the wdDoModifyView method, but I did not figure out exactly what...
Thanks in advance,

Display data in Web DynPro table from database via EJB

I have a JavaBeans model which has a method populateDataToTable()to retrieve data from database via Session bean (calling entity bean, returning ArrayList of data) and the data needed to be display in the Web DynPro table.
User Interface (Web DynPro) <-> JavaBeans Model <-> Busineess Logic (session bean) <-> Persistence (Entity Bean)<-> DB table.
The context bindiing and table part is ok. How do i load the data to the table ? what the coding to put in wdDoInit() ?
Any help would be appreciated.

in wdinit(),
Collection col = new ArrayList();
try{
MyCommandBean bean = new MyCommandBean();
col = bean.getDataFromDbViaEJB();
wdContext.nodeMyCommandBean().bind(col);
} catch (Exception ex) {
   ex.printStackTrace(ex);
in your JavaBean model class, MyCommandBean getDatafromDbViaEJB() method:
Collection col = new ArrayList();
Collection newcol = new ArrayList();
//include your own context initialization etc...
col = local.getDataViaSessionBean(param);
// if your returned result also a bean class, reassigned it to current MyCommandBean
for (Iterator iterator = col.iterator(); iterator.hasNext();) {
    MyOtherBean otherBean=(MyOtherBean)iterator.next();
    MyCommmandBean bean = new MyCommandBean();
    bean.attribute1 = outBean.getAttirbute1();
    // get other attibutes
    newcol.add(bean);
return newcol;

Drag and Drop between Web Dynpro Tables on Cell Basis

Hi Experts,
I need to develop a Drag and Drop Functionality as follows:
I have two tables. I want to drag a row of the first table and drop it in a particular cell of the second table.
Is it possible to implement this using the Web Dynpro Drap and Drop Functionality?
If not, does anybody have an idea of how to implement this using other concepts (Flash Integration, Building up a Grid of Images and defining those as drop tragets, etc..)??
Valuable Advice is highly appreciated!
THANKS, Johannes

Thanks for the Video.. It gives some information about Drag and Drop, but still, it does not say what I need to know.
Again:
I need to know if there is a way to drag particular cells in a Web Dynpro Table to other locations in that same table. Plus: I need to know if there is a way to drag and drop rows of one table into particular cell of another table.
Similar to what we do in our Outlook Calendars: We have a week in view and we see our appointments as blocks within that week view. Now, we can drag and drop these blocks to other locations. That is what I need to implement!
Does anybody have an idea?
THANKS, Johannes

Internet Explorer limitation for Web Dynpro Table Data

Hello everybody,
I am having a trouble while trying to display a Web Dynpro table in Internet Explorer. This table is bound to a Context Node that is filled up manually with code, and for example if I passed more than 116 elements to the node the table only shows 116. Since this issue only happens with IE, I consider that it is related to the client part, something related with JavaScript. Any idea/suggestion?
Many thanks in advance,
Jesus

Hello Siva,
Thank you very much for your response. There is no message error, it is just not showing the entire node content, the weirdest thing is that even though WD is client independent this only happens with Internet Explorer. It works properly with any other browser such as Mozilla FF, Chrome and Safari browsers when the table has above 116 elements. When the table has below 116 elements it works properly with any browser. I have tried with IE6.0 and 7.0 using NWDS 7.0 and EP 7.0 SP 18.
The table is child of a Group element which in turn is child of the Root Element.
Best Regards,
Baez
