Hi,
I'm still having a hard time grasping this. I tried thinking of a way to
trigger an event in the CustomerLogin component to resubmit so the
errors would show, no go. I tried using the onActivate of the container
Page to load things in the CustomerLogin component and then resubmit the
page, no go. I tried using RenderSupport like in the ValidationDecorator
to add the error script, but RenderSupport isn't available inside the
component before the render cycle and it's too late at setupRender phase
or after.
Strangely enough, if I include <t:errors/> in the form of CustomerLogin,
it actually displays the error, which really suprised me when I did a
sanity check. I'm not sure why that gets triggered and not the AJAX
bubbles from the ValidationDecorator that works in other places after
form submit.
At this point if you couldn't tell I'm trying any half-baked alternative
strategy I can imagine to try and make progress. There's got to be
something I'm missing no?
Included below is some related code, this is all triggered by the
activation URL <http://localhost/myapp/index/expired>
Thanks,
Rich

//return this;

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:
