Re: [Springframework-developer] VelocityView and exposeHelpers

[<jue...@we...>]

I've removed the deprecation from "exposeHelpers(Context, =
HttpServletRequest)", as there is a valid use case: instantiating =
further Velocity tools that need a Velocity Context.
=20
I've also added an overloaded "exposeHelpers" variant that takes =
VelocityContext, HttpServletRequest and HttpServletResponse: mainly for =
creating subclasses of ViewTool that depend on a Velocity ViewContext, =
with ChainedContext being the only out-of-the-box implementation and in =
turn depending on HttpServletRequest and HttpServletResponse.
=20
Finally, I've added an overloaded "createVelocityContext" method that =
takes model Map, HttpServletRequest and HttpServletResponse: You could =
potentially create a ChainedContext instance there, if you wanted =
request attributes etc to be visible in the Velocity template mode. =
Tools that depend on ViewContext could then simply take the passed-in =
Velocity Context as-is, passing it into "init".

Betreff: [Springframework-developer] VelocityView and exposeHelpers



Hi.
A guy in the user mailinglist has pointed out a problem.
It tries to configure the velocity-tools in the exposeHelpers method but
he can't since they require a HttpServletResponse (arguably).
Maybe there should be an overrided version of the exposeHelpers method
having both request and response as args.
