create subform using addInstance(), rename the subform, delete it later

Hi,

I have a form where users can enter a case number and click a button.  The button then creates 3 subforms throughout the main form using addInstance().  In the first subform there is a button that says "Delete Section".  Once that is clicked I want all 3 subforms to be deleted.  The user may have created a number of sections so I need to identify the correlating two sections.

I thought I could just rename each subform based on the case number that the user entered and then reference each subform to be removed that way, but it doesn't work.

I can 'apparently' rename the subform, but when using the new name when using removeInstance() it doesn't work.

Test rename of subform:
// this is in the initialization parameter of the field containing the policy number

this.rawValue = "123"
app.alert(this.parent.name);  // provides the current subform name correctly.  
this.parent.name = this.rawValue; // should change the subform name to "123"
app.alert(this.parent.name); // shows the value "123" which is what I would expect and want

BUT

if I now click a button saying: ._123.removeInstance(0);
it doesn't work.
If I now click a button saying: .OriginalFormName.removeInstance(0);
it works.

So it doesn't appear that the subform name is really being changed at all.  It's a ruse  :-(

Any help would be great.

I don't have an answer to your question (I don't use Designer).

One of the Adobe Blogs has been dealing with the Instance manager quite a bit. You might be able to get an answer to your question when you either contact the blogger directly, or by posting a comment in the blog: http://blogs.adobe.com/formbuilder/scripting/instance_manager/
