Re: Action Messages
Ray,
it's not clear what you are trying to do that is different from
standard. Struts puts the ActionErrors in the request by default. The
Messages too.
I used to know this inside out but it's been a year or so... but I think
the key is like this:
request.getAttribute(org.apache.struts.Globals.MESSAGE_KEY);
request.getAttribute(org.apache.struts.Globals.ERROR_KEY);

request.setAttribute ( ERRORS, errors );
but I can't get the messages associated with the property to allow me to
manipulate my page.
What I would like is:
for ActionErrors to be a collection, the I could iterate on the errors and
get the key and the values. I could iterate on the values, or reteive a
specific one.
I want the ability to inspect an error condition and if it exists or not and
generate jsp accordingly with an error message.
Does anyone know how to do this?
it would look like, but I dream too much
c:choose
c:when test='${ not empty ERROR.confirmMatch }'
c:forEach var='message' items='${ERROR.confirmMatch}'
trtdfmt:message key='${message}'//td/tr

Re: Action Messages
Hi, Ray,
Why is what you are doing superior to the standard? The standard is
something like the following and is very efficient, I think?
table
tr
td
!--
ERRORS
--
logic:messagesPresent
ul
html:messages id='error'
li
bean:write name='error'/
/li
/html:messages
/ul
/logic:messagesPresent
!--
MESSAGES
--
logic:messagesPresent message='true'
ul
html:messages id='message' message='true'
li
bean:write name='message'/
/li
/html:messages
/ul
/logic:messagesPresent
/td
/tr
/table

RE: Action messages.
You can fake it and do this... have a hidden span in your page that, just before you submit your form, you display. You will probably also want to wrap everything else in your page in a span and hide it at the same time. I say this is faking it because the browser won't have any idea what's going on on the server, which might be OK. If you want some sort of progress bar though, something that actually has knowledge of what's going on on the server, what you'll need to do is kick off a thread in your Action, and store some reference to it persistently (i.e., session or a database, etc.). Then, you'll have to have a page on the browser with something like a meta-refresh that calls some special Action that can check the status of that thread, maybe get some sort of percent complete or something like that to display back to the browser. Obviously, if faking it is good enough, as it usually is in these cases, that's by far the better choice.

Re: Action messages.
Thanks Frank, Do you have any sample code of using SPAN ? I think this is also good to avoid 2 submit´s click.

Re: Action messages.
I'm not sure what you mean by avoid 2 submit 's click. If your referring to the pooling method requiring a submit after the initial one (potential any number of submits really), then yes, you would avoid that. Here's an example off the top of my head (so the disclaimer is it might not be perfect!): htmlheadtitle/title/headbody span id=pleaseWait style=display:none;Please wait, doing server work.../span span id=mainContent style=display:block; form name=myForm method=post action=whatever.ext Field A: input type=text name=fieldAbr Field B: input type=text name=fieldBbr input type=submit value=Call Server onClick=mainContent.style.display='none';pleaseWait.style.display='block';return false; /form /span /body/html Note the return faksel in the onClick of the submit button... I just did this so you'd see it work, without it the form submission proceeds and you won't see anything because you immediately get no return. Or something like that anyway :) The point is, remove that to try this for real against a real server. I think that'll do it, let me know if you need any further help.
