Ted,
I studied the Stripes API a while ago and found nothing relavant and that‘s why
I came up with the interceptor. At first I was also a bit surprised that the
current action bean’s context was not exposed in the customization APIs
(formatters, type factories etc.).

Thanks for the info. Does it mean there is no built-in global static method to
get the actionbean or context of current thread?

Hi Ted,
To obtain the current action bean/bean context within the formatter (and other
Stripes extension APIs) I use a custom RequestResponseThreadLocalInterceptor
that binds the current request/response/servlet context to a set of
thread-locals during the RequestInit stage and performs a cleanup during the
RequestComplete stage. Then I can access the current request/response/context
anywhere in the „Stripes request processing chain“ regardless of whether the
invoked component exposes the current request/response/context through its API.
Once you get hold of the current servlet request, you can access the current
action bean as it is bound to a request attribute
(StripesConstants.REQ_ATTR_ACTION_BEAN). And once you have the current action
bean, you can access its context.
Note: When using the above technique you just need to keep in mind that the
action bean gets bound to the current request at some stage between the
RequestInit and RequestComplete (I would bet on the ActionBeanResolution
stage). So for example the action bean would not be available during the
RequestInit stage. I think you should not have a problem with the formatter as
its format method is most likely invoked after the action bean has been
resolved and bound, but it is definitely something to be aware of.
Cheers,
Honza

I am using freemarker (jsp should be similar)
<@s.text name="dateTime"
value=actionBean.customeDateTimeString(actionBean.dateTime/>
does not work. I created a method in bean, getCustomDateTimeString() to
generate the special string.
BTW, I am trying to go the route of creating a custom DateFormatter.
How can I reference the action bean/context from within the formatter?
Thanks

Well that wouldn't really make sense seeing as validation is only converting
from a request string to an object. once you have the object, its the jsp that
needs it formatted differently.
At that point you have the object in your action bean and you want to display
it a certain way. you have a bunch of options now. you can create a getter that
does the formatting manually and call that from the jsp. you can use a jsp tag
to convert it ( most useful if you want certain dates to display differently).
or if you are using the object as a form parameter, you can register the type
converter for the class and that's where the auto conversion happens. but now
you are limited in that all dates are formatted this way.
In the end if its just for display, a fmt tag is the best route because you can
use different formats wherever you want. Id argue that's the jsps
responsibility anyway.
