Re: prepopulating a dropdown box _in_a_struts_way_.

[Adam Hardy <ah...@cyberspaceroad.com>]

There are also limitless ways in struts of instantiating the lists of 
beans or values for dropdowns.

In my experience the only factors involved in making a list available to 
a JSP taglib are: (1) which list is needed (2) what parameters are 
required to constrain the list and (3) how long it should be cached for.

I think this is widely known as 'view logic' - and there's a whole heap 
of functionality coming up in future versions of struts to help on the 
view logic front, I believe. Since I am currently in retro-mode working 
with 1.1 at my current job, I'm not sure what version brings view logic 
- anyone?

I envisage at some point a view logic component that integrates with the 
taglibs and some config xml to allow struts developers to set up 
dropdown lists without mixing it in their actions, with declared cache 
levels (application / session / request scope), automatic i18n with 
substitution of resource strings, and stuff like that. Does this match 
anyone else's plans?
