Livecycle Designer ES8.2


Not applicable

I've got the following problem:

I want to remove and add a subform using "setInstances". In the sample files, there is an interactive purchase order example using a JavaScript and although I use the same syntax, nothing happens.


Do I have to make any specifications beforehand? What other failure sources could there be?

The subform which is to be added/removed by clicking on a button (Butoonchildren) is called "children", and the JavaScript used is the following:

form1.personal.childrenHeader.Buttonchildren::click - (JavaScript, client)

if (_children.count == 0) {


this.resolveNode ("caption.value.#text").value = "Clear Subform";


else {


this.resolveNode ("caption.value.#text").value = "Add Subform";


The important thing for me is to add/remove the subform; it is less important whether the text shown on the button changes or not.

Help is greatly appreciated - thank you!

I've got the following problem:

I just started using Livecycle Designer ES8.2.

I have a program with 140 dynamic forms, coded by somebody no longer around.

I am only able to see a few (30) of the forms in the "Design View" from all the members in the Hierarchy Pallette (140). Is there a filter or a function limiting the members been display in the Design View?
