<p>Hi there,</p>
<p><br>
</p>
<p>we've been using a WAHtmlErrorHandler for quite a while in our
application, but there are some limitations to that appraoch:</p>
<ul>
<li>If an error happens in a subcomponent, the HTML Error handler
will only be displayed in place of the failing component, not as
a page of its own. This is irritating for quite a few users,
some even don't realize an error occured and contniue clicking
and stuff...</li>
<li>I haven't found a way to allow the user to go back to the last
page and redo their changes</li>
</ul>
<p>Let me give you an example of what I'd like to achieve:</p>
<ol>
<li>A user submits a form and thus a callback is called on the
server</li>
<li>The callback handling code runs into a resumable exception</li>
<li>We display a full page saying: "Hey, this and that is wrong,
you better go back and change your input" <br>
(Unfortunately, the situations I am speaking about cannot be
validated before the user submits - think of it as an optimistic
locking failure)</li>
<li>This error page offers a "I want to go back and be a good user
and correct my input" link or button. It is a root component,
coverng the whole page under all circumstances</li>
<li>The callback of that link does resume the exception, maybe
clear up some data and go back to the component the user came
from<br>
</li>
</ol>
<p><br>
</p>
<p>Has anybody done this? Is it described somewhere?</p>
<p>Thanks,<br>
</p>
<p><br>
</p>
