force resultset as array

Hello,

I have small problem with TT while getting DBIx::ResultSet. For instance
I have stash variable team which ich DBIx::Result (one entry). In DBIx
exists relations team_accesses as has_many. So in TT I am using:

team_accesses = team.team_accesses;

Problem is: 
	when team has no accesses, variable team_accesses is empty string ('')
	when 1 access exists, variable contain hash which is result
DBIx::TeamAccess. 
	when exists more than 1 access, variable contains array of
DBIx::TreamAccess.
Is the way how to say TT, that result needs to be converted to array?

I tried: team_access = [ team.team_accesses ], but my results are,
[ '' ], [DBIx::Result], [[DBIx::Result]]

Thanks for help
