public class Context extends SimpleBindings
ActionRequest context.
The request context is mapped to a proxy instance of the bean class on which the action is
being performed. The proxy instance can be accessed via asType(Class) method.
Example (Java):
Context context = request.getContext(); SaleOrderLine soLine = context.asType(SaleOrderLine.class); SaleOrder so = context.getParentContext().asType(SaleOrder.class);Example (Groovy):
def context = request.context def soLine = context as SaleOrderLine def so = context.parentContext as SaleOrderThe instance returned from the context is a detached proxy object and should not be used with JPA/Hibernate session. It's only for convenience to get the context values using the bean methods.
