insertInstance fails on second row

InsertInstance function doesn't seem to work on Row1[2] and beyond but it works for Row1[0] and Row1[1].

Basically insertInstance generates errors whenever there's more than 1 row instances premade inside Designer.

Error: Index value is out of bounds

Picture below is of object hierarchy.

Each "+" button calls the addRow function inside the script object

Hi,

I think radzmar is correct in suggesting renaming the rows.  The index property in a reference like currentObj.parent.parent.index is meant to return the position in like named objects, which in your case includes "Row1[0]" you have defined in the template.  So it is not insertInstance you are having trouble with but the index property.

You can use an expression like;

     xfa.resolveNodes('Table1.#subform.[layout=="row"]')

to return a list of all the rows in a table regardless of the rows name.

Thanks for the response.   I'm aware of the workaround of naming each row uniquely. 

Because the code uses length from resolveNodes to count the number of rows, all the rows have to remain as instances not unique names.

Is there a way to work this without remaining the rows?

Instead of naming all rows "Row1", you should name them individually.

The script then could be:

if (this.parent.parent.instanceManager.count < 100) {

    this.parent.parent.instanceManager.addInstance(true);

}
