Thanks.
There are a couple of issues.
1. The Submit button's Postback settings must be set to "Always".
2. In the mapping file, I see:
<RepeatingGroup>my:myFields/my:Inspectors/my:InspectorsGroup</RepeatingGroup>
<Relationships>
<RelatedList />
<RelatedListId />
</Relationships>
<Mapping>
<FormField IsRichText="false" IsId="false" IsAttachment="false">my:myFields/my:Inspectors/my:InspectorsGroup/my:InspectorName</FormField>
The FormField (underlined and bold) must be relative to the root node (bold).
3. Non repeating fields must also be relative. Instead of
<Mapping>
<FormField IsRichText="false" IsId="false" IsAttachment="false">my:myFields/my:GeneralInfo/my:TicketNumber</FormField>
You should use
<Mapping>
<FormField IsRichText="false" IsId="false" IsAttachment="false">../../my:GeneralInfo/my:TicketNumber</FormField>
I have attached an updated mapping.xml. Hope this helps.
