Maybe you could show more of your .tml (and .java) file(s). I'm new to Tap5 and all I've discovered so far in the realm of models is how to supply a one to a BeanEditor and to a Grid. I've never gone to the level of t:gridcell and from what I've learned one generally does not need to -- you can configure a lot at the t:grid level and via nested t:parameter elements.
