Well the solution for your problem is the one below.
I don't if your using velocity to generate your tiles file (I use velocity
just to build SQL/DAOs with the OJB framework).
If this is true, then you just have to make it generate a tiles file with a
controller class defined by you.
The runtime argument must be handled by you, programatically, in your own
tiles controller class.
