Hey everyone,

I've been asked to build a form that is way more complex than anything I've done in the past. I just wanted to ask the experts here a few questions before I get started, to make sure that I don't make any huge mistakes.

The complexity of the form lies in the huge number of nested repeatable subforms, the fact that it's three forms in one (which form being shown depends on a selection from a drop down list), and the fact that the form needs to be designed to export its data cleanly to xml.

As far as building the form goes, I'm comfortable with everything except for the exporting to XML. I've done this a few times, but I'm not sure that the assumptions I've made are correct. I've tried reading the help files, but I'm not sure I'm getting it.

Pretty much, I make use of a ton of subforms in order to make sure that the layout of the form works dynamically. I don't want all of these subforms to show up in the xml import. The way I've been doing it is to set the data binding on these subforms to 'No data binding.' Does this have any impact on how data is saved to the form? If I don't want the value of a field to be exported, can I set it's binding to 'no data binding', or will that cause prevent the values from being saved?

My final question is about the 'Use name' binding. Up until now, in past forms I've made sure that all fields have different names. This form is so large, and has so many similar elements that it would be useful to be able to resue field names in different areas of the form. For example, two of the versions of the forms has a section for associated addresses. The fields in these sections are the same. Can I name them the same thing, so long as they are within different subforms? Or will this cause a conflict when exporting/saving.

Sorry for the long post. In short:

1) What afftect does the data binding 'no data binding' have on subforms and fields, with regards to saved data and exported data? Are there any 'gotchas!' that I should be aware of?

2) What are the guidelines I should follow to ensure that I don't come across any naming conflicts? Do I just need to ensure sibling feilds aren't named the same, or should all names be distinct?

I would appreciate any help that you guys might be able to offer.

- Scott

Scott,

1) No date binding means a form object is not included in exported XML. Data binding has no effect upon saving data when saving a form, the form will contain the data.

2) For me, rule #1 is use a schema and schema binding. It is worth the upfront investment in time. What you see in the schema is what you see in the output data, given a form object is bound to the schema. You can bind a single schema element to multiple form objects if you need to re-use data across sub-forms, also. Rule #2, again for me, is to explicitly define sub-form names to simplify schema binding and avoid name collisions.

I've attached a very simple form (with the schema embedded), the schema and exported xml to demonstrate.
