Form preprocess - jira

Question

Hi, I have an action class responsible for form preprocessing: public class ManageTemplates extends JiraWebActionSupport method is connected with view:

Select user/s

And I want to get form parameters... The easiest way is to get params via request object, but I think that's not best practise. How should I serve request? I would appreciate for source code examples:)

Hi, some webwork example below.
