Hello,
I am currently developing a custom connector.
Is it possible to create a selection field like the "Count" in the Hello World Sample Connector:
In this selection field, however, should the selection values be generated dynamically.
Specifically, the possible values should result from a result of a NativeQuery from a database and, for example, map the schemas of a database.
Is it also possible to create several selection fields and make their results dependent on each other?
For example, I want to select a schema in the first field and a table that exists in this schema in the next step.
Thank you very much!
Solved! Go to Solution.
@tanito In the sample, the record is hard coded but there is no reason why you shouldn't be able to make this dynamic but I will have to test. As long as you bring the data back as a record (single field). Documentation.AllowedValues = {1, 2, 3} <-- this is an ad-hoc record
For the second part, making them dependent on one another, I don't think that is possible given what they have exposed via the UI, which is very basic. It might be better to instead build the hierachy as part of the Navigator dialog if possible.
