Hi John, I'm pretty sure I'm not following you. Here's my understanding:
I currently have an ActionCell in an IdentityColumn. You're saying I can replace the ActionCell with a ButtonCell. I need to have a class implement FieldUpdater<T, C>, and pass that to the IdentityColumn that holds my ButtonCell. T is the class of my row object. C is ??? So you're saying that clicking on the button will fire a ValueChange call that will cause my FieldUpdater to have update (int, T, C) called, which can then use the T parameter to fire off my command? Other problem: ButtonCell implements Cell<String>. But I need to pass it my row object, so that it can change its title based on non-string information in the row. (i.e. I want one button that will say "Show 'x'", where x is the number of items in a list in the row object, or to disable the button and put "Nothing" as the title if the list is empty. I don't see how I can do that with a ButtonCell. Am I missing something?
