I have a connector that selects data from an external database in Bonitasoft, I was able to assign the result of this select to a process variable and display the contents of that variable in the UI Designer in an Input type field, however I need to display this in a table, as I configure This in the UI Designer to display the contents of my process variable in a table, if possible show the step by step thank you. Another thing as I can also pass the contents of my connector to a business variable and then display in UI Designer also if needed
First of all I want to draw your attention that using business or process variables to store data already stored in an external database will lead to duplication. Recommended solution would be to use a REST API extension (such as REST API SQL data source) to query the data from the external database and use this REST API extension in the forms.
Now if you are ok with duplication of data you can refer to an example I create that demonstrate how to set process and business data with PostgreSQL connector output and then display the variables in form table widgets.
I highly recommend to use business variable and if possible consider migrating the data from the external database to the business data database.
