I've tried to approach the problem from different angles, but unsuccessfully.
Let's suppose the following scenario (that's what I'm working on right now actually). You have an event registration form and you may register another participant with you; you're using suggestion (autocomplete) to enter other participant's name; if this person is already in the system, field is marked with a checkmark; if not, user is prompted to enter email so the system could send an invitation upon form completion. What do we need to implement it? 1) handle autocompletion selection event (that's already done, the resulting mixin is pretty straightforward once you realize the mechanics of jQuery autocomplete). 2) update the form based on autocompletion result. Now, here is a problem: - if we use a component event request that updates form zone, yes, we can get what we want, but everything user has entered into other fields is lost; obviously this is not acceptable - if we trigger form submission (it's possible to do that using hidden submit, it's not very elegant, but it works), we have to go through form validation which fails in most cases because at this point form is not yet completed; user receives non-relevant validation errors - FormInjector might be a solution, but it can only add something to a form, rather than update its current controls So none of the above can actually solve the problem. Are there any other approaches to this? -- Ilya Obshadko
