OT RE: Deprecated: ActionError

[Richard Hightower <rh...@arc-mind.com>]

It's is hard to argue with sound reasoning like canine's genitalia and queen
of abomination.

What don't you like about this? You never stated a reason.

:)

The html:errors tag forces you to put HMTL markup in the resource bundle.

EVIL! (sorry I could not think of a something catchy like canine's
genitalia)

Resource bundles are for I18N not HTML markup.

I don't see a problem with <html:errors property="foo" />.

I am trying to understand. What is the beef?

Sure I know how to get the messages out using html:messages but i cant
see how this improves on html:errors

I've tried using jstl to drill to the specific error but just cant do
it.

<c:out value="${messages.errors.foo}" />

Sorry I'm sure there are lots of great reasons, but

<html:errors property="foo" /> was the canine's genitalia IMO and the
messages lib to access errors is the queen of abominations in respect
to html:errors ..

Re: OT RE: Deprecated: ActionError

[Mark Lowe <ma...@talk21.com>]

Now i know that the deprecation of ActionErrors != deprecation of 
<html:errors

no beef at all. I just don't like

<logic:messagesPresent bla bla


<p class="error"><html:errors property="foo" /></p>

works just fine, no formatting in props file.

thats enough, i'll leave these folk to get back to their work. and i'll 
continue lurking on the list rather than talking.

cheers mark
