Heres a simple form to help illustrate the issue. This is not the complete code for a form since it was way too long (or bloated rather) to post. So if you open Adobe LiveCycle and create a blank document, insert the following as the main content.
Then save it as a pdf. If you open the pdf and save it you'll see the subform went from showing up once to showing up twice. Does anyone see why this code/markup would cause another instance of the form to be created when it has been saved?
I'm not that familiar enough with LiveCycle to understand all of the generated syntax, but it doesn't seem like anything should be doing this. I thought that maybe the buttons responsible for adding another instance of the form were firing without me knowing, but that doesn't seem to be the case as removing the buttons entirely doesn't resolve the issue.
