What do you mean by dynamic? It has a very particular meaning in LiveCycle/XFA which is to grow or shrink the form based on data. Acrobat has no support for editing dynamic forms, as it can only edit AcroForms, which are static.
I too have a need to edit a form created in LiveCycle Designer. I see now that it has been renamed to Adobe Experience Manager Forms (AEM Forms). Getting a trial version requires working with a sales person. Not so interested in that...
Proposed Use: We will use the dynamic form as a template in a software program that will populate the fields and spit out a completed form?
Issue: We need to edit the field behavior of some fields to allow the entry of decimal points. Right now, the fields only allow whole numbers.
Can I take an interactive PDF form and convert it to dynamic in (AEM Forms)?
Is there a way to create a new dynamic form in Acrobat? Using the (AEM Form) to start with or from scratch)
Can I open the dynamic file (AEM Forms) in Acrobat and edit? Keeping it dynamic.
