Add instance in a subform which also can be doubled

Question

Hi,
I have a subform X which can be doubled by a click on the button. In that subform X there is another subform Y which also can be multiplied to a maximum of 3.
Now when I add a subform X and i want to add some subforms Y. The form will only add the subform Y in the first subform X and not in the second one.
This is the script I use:
for subform x
if(Incitant52.subFoireAcheteur.all.length < 2){;
Incitant52.subFoireAcheteur.instanceManager.addInstance(true);
and for subform y
if(Incitant52.subFoireAcheteur.subAcheteur.all.length < 3){;
Incitant52.subFoireAcheteur.subAcheteur.instanceManager.addInstance(true);

Answer 1

To add instances to the second occurance of subform x you will need to address it with subformx[1].
Note that the [ ] brackets are not valid in javascript so your expression should look something like this:
xfa.resolveNode("Incitant52.subFoireAcheteur.subformx[1]").instanceManager.addInstance(1)
