Backoffice : How to populate reference editor values based on user input.

Hi All,

For one of my requirements, I want to populate reference editor values defined in one of the step and this values will be based on user selection in previous step.

So, I have 2 items suppose A and B and have one to many relation defined in items.xml. In ConfigurableFlowWizard's step1, if user choose any value of item A and click next then only associated values must be prefilled in reference editor for item B.

What can be the best solution for this kind of problem?

Thanks, Ved
