[T5] Inline display of general exceptions
Hi there,
I would like to display exceptions that occur in my pages in a user friendly way. Mostly they originate from the underlying Web Service Backend.
I like the layout used by the "Errors" component (red square). So my first thaught was: why not use this component. However, when trying to achieve this I found that the purpose of 'Errors' is to display ValidationExceptions that occur in forms.
How can this mechanism be extended to general runtime exceptions thrown in onActivate() and possibly other event handlers?
I know how to customize ExceptionReport, but this is not what I want. I would like to see those red squares on the top of the screen that are embedded in the page.
Thanks for any advice.
Lothar

To be honest, I'd define a different object to store the exceptions,
and a matching component to display them.
For one of my clients, I've been working on a generalized way to store
application messages (info, warning, error) and control how long they
are displayed (once, until dismissed, until page changes). I may be
able to spin that off into a general purpose library (perhaps under
the tapx umbrella).

Not just validation errors. You can get the ValidationTracker from the
Environment and use void recordError(String errorMessage) to record a
message.
@Environmental
private ValidationTracker validationTracker;
Or inject the form and use the recordError() (which just delegates to the
ValidationTracker.
