When you drag the table back in, go to the Property Editor, under Binding, and click on the Data set Binding button. Make sure it is set to the proper value of the parent table.

This was a example that i was studying, but in my main project the problem persist.

I have an entity Person and this person can have a list Kids.
for both entities i have a respective dataset.

Person: OPEN

hMap = reportContext.getPersistentGlobalVariable("data");
person_iter = hMap.iterator();

Person: FETCH

if( person_iter.hasNext() ){

personAux = person_iter.next();
person = personAux("person");

if ( person.getName() != null ){
row["name"] = person.getName();
}

return true;
}else{
return false;
}

Kids : OPEN
kids_iter = person.getKids().iterator();

Kids: FETCH

if( kids_iter.hasNext() ){

kids = kids_iter.next();

if ( kids.getName() != null ){
row["name"] = kids.getName();
}

return true;
}else{
return false;
}

for now i just want to show the name of the person and the name of their kids. The name of the person always appear, but the name of the kids never, but i have the names in my variable, i checked using SystemOutPrint.

I tried to solve this, the same way the previous sample, but i cant.
The dataSets have only one output (name).

Do you have an ideia, how should i try to solve this ? Thxx ^_^
