Hi,
I believe you can achieve what you want by grabbing the ValidationTracker
from the Environment. The Form component pushes it to the environment during
beginRender and pops it in cleanupRender, your component will beginRender
after the form.
you would do something like:
@Inject
Environment _environment;
void beginRender() {
...
ValidationTracker tracker = _environment.peek(ValidationTracker.class);
tracker.getHasErrors();
}
I haven't run, or even compiled this code, and I'm still back in 5.0.6 so
perhaps something has changed, but I'm fairly certain it should work.
Good luck,
Josh
