Setting table row value from java code

Hi, I have the following class as a handler for a particular detail row in one table of my report. I plan to dynamically enter data for this row. How do you set values from this method?

public class TableRow extends RowEventAdapter {

@Override
public void onCreate(IRowInstance rowInstance, IReportContext reportContext) {

rowInstance.getRowData().getColumnValue(0)="Some value"; //This throws an error for obvious reasons. What is the alternate?

}
}

Thanks in advance

Once you have the row handle you can access the cells directly using: 
rowInstance.getCells().get(i) 
where i is the cell index. 
 
I am by no means an expert but this should work. Also look at:

Couldn't find .getCell() method, thers only a .getRowData()..

Tried in all the methods for the table (onPrepare,Render,Create)

This is a Birt 2.2.2 example

I have put together an example. I am using javascript but the classes are the same and you should be able to deduce the java classes. You will see I have a table that I named "MyTable" (look in properties). If you highlight the detail row and click on script you will see the script. It is very simple and does the following:
- Gets a handle to the table using the name
- Gets a handle to the first row
- Creates to labels and inserts them in each cell

You can dynamically add a row if you like by using something like:

rowParm = new RowOperationParameters(2, -1, 1);
dynamicTable.insertRow(rowParm);
myNewRow = dynamicTable.getDetail().get(1);

I hope that this will help

thanks, that helped

Glad to be of help :-)

Monma,

Based on your JavaScript code, I was able to convert it into the equivalent Java code:

ElementFactory ef=reportContext.getReportRunnable().getDesignHandle().getElementFactory();
TableHandle handleTable= (TableHandle) reportContext.getReportRunnable().getDesignHandle().getModuleHandle().findElement("dynamicTable");

RowHandle myRow=(RowHandle) handleTable.getDetail().get(0);
//Fetching existing detail row. How to dynamically add these detail rows???

CellHandle firstCell=(CellHandle) myRow.getCells().get(0);

CellHandle secondCell=(CellHandle) myRow.getCells().get(1);

LabelHandle label1=ef.newLabel("Label1");

try {
label1.setText("First label");
} catch (SemanticException e) {
// TODO Auto-generated catch block
writeToFile(e.toString());
}

try {
firstCell.getContent().add(label1);
} catch (ContentException e) {
// TODO Auto-generated catch block
writeToFile(e.toString());
} catch (NameException e) {
// TODO Auto-generated catch block
writeToFile(e.toString());
}

Is there a way to dynamically add the detail rows as well instead of fetching existing ones and adding labels to them??

I am not sure I understand. You are adding rows dynamically. The labels are not necessary you can also use a data element or any other element that can hold your data.
