Exercise: connecting the Application Layer to the Data Layer. Data page does not fill
Hi,
Can anybody provide me/us with this exercise a screenshot of the Data Transform rule the Data Page uses to map the data from the ..Data.. class to the ..Interface class as described in the documentation? Though I created the Data Page in the right class, together with the Data Transform, the latter does not allow me to 'smart prompt the right data fields. Testing the Data Page does not return any results in the XML, just a message saying: 'valid'
Thanks
regards,
Maarten

Sorry for the delay.
Here are a couple of screenshots of the data transform used.
and the pages and classes tab (this should already be set for you if you use the magnifying class to create the data transform)
let me know if this helps
Hi,
Following on above issue, I tested the database connection of my dataclasses. Both return an error on a key mismatch. I followed the exercices putting the right property key in. But both for pa_account and pa_contact, the error suggest these properties have not been set as the table keys. Below the errors:
There is a key mismatch: the keys defined for class Edu-B2B_CRM-Data-pa_contact do not match the primary key columns for external data table public.pa_contact in database CourseDB ; the class keys are [ContactId] , but the table's primary keys are []
There is a key mismatch: the keys defined for class Edu-B2B_CRM-Data-Account do not match the primary key columns for external data table public.pa_account in database CourseDB ; the class keys are [AccountNumber] , but the table's primary keys are []
