Dropdown doesn't work when creating a new row in a table?

Hi Lars,
I hope this comment helps.

Dropdown produces 'no data' when adding record into an empty table

I have solved this issue by myself. if a query doesn't have no return record, table data should be set as "query.dataArray" like below. But I can't find the query parameter to judge whether there are some return record, so that I use a primary key column of my custom table. [image]
