Handling User Interaction
These methods are used to create prompts that will be shown to the user. They are useful for automatically generating parameter pages. The template that is used to create the layout of the page is specified by the action sequence and can be either an HTML template or an XSLT template. If a template is not specified a default XSLT (system/custom/xsl/DefaultParameterForm.xsl in the solution folders) is used.
