Thank you for your response and helpful insight. Based on your
comments and my further research, it appears that a secondary data source (XML
in my case) does not store data and therefore when I open my form to edit it in
SharePoint, the data is not showing in the controls due to the data not being
stored in the controls because the I am using a secondary data source for the
non-repeating controls.
With that being said, how can we fix the issue we are having
while keeping the secondary data source in place? In other words, is there a
workaround to have the data show in these controls when we open the form while
keeping the secondary data source in place? We need this secondary data source
to be able to put non-repeating controls (for data that is consistent for all
line items).
Regarding your comment about making the project name a field in
the list…do you mean make project name a field in the XML list? If so, can you
give us the code for that…is it something like <Field:projectname
/> ?
