For my DataConnection I am using the following connection string:
https://sharepoint.mycompany.com/departments/legal/contractmgmt/_vti_bin/listdata.svc/Contracts()?$select=CompanyName,ContractDateNeeded,Id,CompanyContact,StartDate,CompanyAddress,CompanyCity,CompanyState,CompanyZip,CompanyContactPhone,CompanyContactEmail,ContractAmount,ContractType,BusinessUnit,ContractNotes
this statement seems to work fine, as I can view my results in the browser and in the form if I do a filter on the Change REST URL and execute the query again.
Once I put in the ID number in (), I do receive a reply from the browser, and I can see the data by viewing the source but, agreed, I do not get a result when executing through IP
https://sharepoint.mycompany.com/departments/legal/contractmgmt/_vti_bin/listdata.svc/Contracts(366)
other example above in thread...
For now, I abandoned using the id in the () and am filtering on another unique identifier, although I think it would be smarter to be able to use the ID within the brackets for selecting the data.
I have reviewed your video a few times and it looks very similar, just different results.
One question I did have was how did you get the data from the user information list? I tried https://sharepoint.mycompany.com/_catalogs/users/_vit_bin/listdata.svc but that did not work. This data would be very handy.
Thank you,
