Hi,
a somewhat related question. It's now possible thanks to the Decorator
for my webapp to display validation bubbles after a form submit. I'd
also like to be able to set an error somewhere in the beginning of the
rendering process and have it show. I'm having a hard time figuring out
how to accomplish this. By the time setupRender or beginRender occurs,
it seems the form.recordError(String) method and its overload do not
affect the current render cycle.
I tried doing something along the lines of dumping the first render
cycle, returning false at a late render cycle and going back through,
but that doesn't seem to do anything useful.
To give more perspective, my application manages a session timer, and
when the timeout occurs the user gets booted to the main page. As before
I don't want to introduce more text to the page and would prefer to have
the login form of the main page grab the user's focus with a "Session
has timed out" pop up bubble.
I am passing an activation context to the main page, and having this
pipe into the login component via a parameter. The trouble is what can I
do within the Login component to display the popup error when it becomes
aware the parameter for the session timeout is triggered.
Thanks,
Rich

Thanks Josh,
that was exactly what I was looking to do. Hopefully I'll be able to
start seeing these things on my own sometime soon!

If you are looking to get the error bubble to pop up after you submit
the form you could use this:
public class BubbleValidationDecorator extends BaseValidationDecorator {
private final Environment _environment;
private final RenderSupport _renderSupport;
public BubbleValidationDecorator(Environment environment,
RenderSupport renderSupport) {
_environment = environment;
_renderSupport = renderSupport;
}
public void afterField(Field field) {
final ValidationTracker validationTracker =
_environment.peekRequired(ValidationTracker.class);
if (validationTracker.inError(field)) {
_renderSupport.addScript(
"$('%s').getFieldEventManager().showValidationMessage('%s');",
field.getClientId(),
validationTracker.getError(field));
}
}
}
Add to AppModule:
