Where to get struts repository

We have a struts application where we use struts-menu (just upgraded
from 2.3 to 2.4.1-went pretty seamless once I got the right collections
jar).  

 

The repository for each user is generated dynamically.  The menu is used
in a form to allow the user to select preferences-the menu items are
checkboxes.  Works very nicely.

 

Currently, I place the repository in a request attribute
('reqRepository') and then set the 'repository="reqRepository"'
parameter in the useMenuRepository taglib.  That also has been working.

 

Here's the problem.  I am moving from a homegrown form validation
mechanism to the standard struts validator.  The problem is that if
there is an error on the form, then the form is redisplayed.  However,
since the repository is in the request context, it is gone if the form
needs to be redisplayed with form validation error messages (and hence
the taglib throws an exception since it can't find the repository and
the jsp page generation terminates prematurely).  I'd prefer not putting
the repository in the session context as then I have to worry about
getting rid of it.

 

I thought the solution might be to make the repository another field in
the struts ActionForm since the validator seems to keep the form intact
even though it's a request object.  But, I if I write
'repository="{myForm.myRepository}", then it doesn't work (presumably,
because the taglib is looking for an attribute name).  

 

Is there a way to accomplish what I want without putting the repository
in the session context?
