Hi Scott,
Thanks for your reply.
I did not realize that globalOnly was a property of af:messages. In that
case,
I say that by default we SHOULD render all messages just like the desktop.
The
user can choose to set globalOnly to true for PDAs if they want. This gives
ultimate control to the user.
In terms of the disclosure, etc., I don't think we have time for that. For
now I want
to implement it as the desktop does, to limit the number of areas the app
developer
might have to configure.
I agree that the renderers for PDAs and Desktop should be different.
Thanks,
Piyush

Subject: Re: "messages" component on PDAs
Piyush,
I don't know why the messages don't display at all. I agree with you that
they should.
Beyond that, I don't agree with anything else. I think the rendering of
the messages component on a portable device needs some special attention
that cannot be "solved" in the base renderer. As for not rendering
component level messages, there is an API on the messages tag called
"globalOnly". Disregarding this attribute and NEVER displaying the global
messages is bad form. Especially since an app developer can adjust this
for themselves using an EL expression and some logic to detect formfactor.
A better implementation might be to display global messages and then (if
globalOnly is false) put the component level messages in some sort of
disclosure or provide a nav icon or something with a way to return back to
the original page..

Hello,
I have two questions regarding PDA renderers for "messages" component.
*1) Can we make one common renderer for PDA and Desktop for a "messages"

Desktop and PDAs have different renderers for a "messages" component.
They are both located in
org->apache->myfaces>trinidadinternal->ui->laf->base->pda/desktop->MessageboxRenderer.java
With current trinidad code, on a desktop, the demo-app renders a message
box that displays messageType (like Error) and the message (Label :
Conversion Error) in the following format: (see desktop_messages.JPG)
On Pocket PCs (PIE and IE mobile) PDA message box is not rendered and it
displays nothing.
I did not understand why in the first place we need a different renderer
for PDAs ? So, I tried something different. I copied the contents of
DESKTOP MessageBoxRenderer.java into the PDA MessageBoxRenderer.java of a
PDA. And it worked !!! PDA displays errors in the desired format.
Everything appears same
as desktop except the skin and the absence of Error Icon (X) on left of
Label which I think are skinning issues. (see pda_messages.JSPX)
*2) Since, limited screen size is a handicap on a PDA device, it does
not make sense to show messages that are specific to a component (in this
case an inputText) within "tr:messages" component (Label : Conversion
Error) as well as below the component they belong to. (ex: Specified
value is not a val....).*
*In that case, shall I alter the PDA renderer from 1) to exclude any
messages being added to the "messages" component if they are specific to
a component?
*
** Sincerely,
Piyush Hari
