You could do it with a simple crosstab.

See attached example.

Interesting solution but i don't want to print the values in a table.

I really want a String with comma separated values.
More one thing, i would like to limit the number of elements and if the
size is greater, add "..." at the end of the string.

Best regards

This can be done by doing the following:
1 - add the table to the report.
2 - set its visibility property to hide it for all formats.
3 - add oncreate script to table to initialize javascript array and var.

myarr = [];
i=0;

4 - add oncreate script for row to load the array

myarr[i] = this.getRowData().getColumnValue("col1");
i++;

5 - add a text element (make sure to set it to html) after the table to
build the string you want using the array.

<VALUE-OF>var teststr="";
if( myarr != null ){
for( j=0; j<myarr.length; j++ ){
if( teststr.length > 20 ){
teststr = teststr + "...";
break;
}
if( j == (myarr.length-1)){
teststr = teststr + myarr[j];
}else if( j == 0 ){
teststr = myarr[j];
}else{
teststr = teststr + "," + myarr[j];
}
}
}
teststr;</VALUE-OF>


See attached example.
