InfoPath Dev

I've got a problem with my InfoPath form where I am unable to isnert a choice section between two choice sections of the same kind in a repeating choice group.  When I insert the section, I receive the following error:

InfoPath cannot insert the section or row because of an error

The attempted fragment operation cannot be completed because there is no valid insertion point for the fragment

My XSD Date Source for the form is as follows:

 <xs:schema>
  <xs:element name="richBody">
    <xs:complexType>
      <xs:sequence>
        <xs:choice maxOccurs="unbounded">
          <xs:element name="element1" maxOccurs="unbounded"/>
          <xs:element name="element2" maxOccurs="unbounded"/>
        </xs:choice>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

When my form opens, element1 is the default choice section, and is automatically inserted into "richBody".  Now I want to insert another element1 section after my first element1.  I now want to insert element2 after the first element1.  This is when I get the error.  The error doesn't occur if I add element2 after element1, then add a second element1 after element2.

Hopefully this makes sense, and somebody can help me out with the problem.  I'm running close to a deadline, and I am not sure what to do at this point.  Thanks in advance!!

Anybody know why I'm having this issue?

The problem is that your schema is not properly defined. The key issue is that you are marking your individual elements as repeating (i.e. maxOccurs="unbounded"). These are not what gets repeated, it is the choice that gets repeated. If you did nothing other than remove the unbounded from element1 and element2, you'd stop getting your error.

However, the safest thing to do is to create a choice schema in the InfoPath designer and then model yours after the way InfoPath "likes and expects" the schema to be. That is how I figured out why yours wasn't working. I just compared yours against one created in InfoPath.

Below is an example of your schema upgraded to look more like the way InfoPath would design one. Note that the main difference is that the choice is inside a group and not directly off the root--but that isn't required.
