Problems with ActionMessages... (again)
Hi,
I´m just not getting anywhere with the ActionMessages. I wrote to the
mailing list about a week ago and got no answer. Unfortunately since
then, I still haven´t managed to solve the problem myself.
Aaahhhrrrgggg!
I´m trying to display a message in my jsp which I have defined in my
action as follows:
ActionMessages messages = new ActionMessages();
ActionMessage newMessage = new ActionMessage("regform.myMessage ");
messages.add(ActionMessages.GLOBAL_MESSAGE, newMessage);
saveMessages(request, messages);
And in my jsp:
<html:messages id="message" message="true">
<bean:write name="message"/>
</html:messages>
I´m getting exactly the same error as described in the thread below
(which also received no answer on this topic):
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg34621.html
If anyone knows how to solve this, please help!
Regards,
Michael

Sorry for my previous mail,
I forgot to remove something
that is what i wanted to say :
I am amazed that nobody answered you ...
so, I will do my best
maybe you should use Action.MESSAGE_KEY instead
ActionMessages.GLOBAL_MESSAGE
it seems it's what it is specified in
http://jakarta.apache.org/struts/userGuide/struts-html.html#messages
message : By default the tag will retrieve the request scope bean it will
iterate over from the Action.ERROR_KEY constant string, but if this
attribute is set to 'true' the request scope bean will be retrieved from the
Action.MESSAGE_KEY constant string. Also if this is set to 'true', any value
assigned to the name attribute will be ignored. (RT EXPR)

Xavier

Did not found doc about Tokens
Posted by Xavier Combelle <xc...@kaptech.com>.
I post this message because I did not found any doc about the
createToken, isTokenValid, resetToken API.
So I will explain what I understood about it from the struts-exemple
if something is wrong, I would like that someone will say to me
and if there is some doc tell me where ...
The token API is created to avoid that the user
to submlit twice the same form.
It is used with one ActionForm and two Action:
- the SomethingForm which contain the user's input
- the EditSomethingAction which populate the SomethingForm from the DB or
clear all the field if it is a create Case
- the SaveSomethingAction which save the SomethingForm in the DB
To avoid that the user call submit twice the SomethingForm and
save twice the same data in the DB,
the struts framework propse the xxxToken API.
It is used as following
in EditSomethingAction, make a call to createToken(request) and that all !
in SaveSomethingAction, make a call to isTokenValid(request) and
resetToken(request)
as in the following algorithm
if ( ! isTokenValid(request) )
{
/*
* return forward towards an error page
* saying to the user that he has submit twice
* or
* forward toward the succes page if we don't want the user see anithing
*/
}
else
{
/*
* process the save in the DB
*/
if ( allTheSaveHasSucceed )
{
resetToken(request) ;
}
}
You much take care that there is only one token in the session
so that this process can't support nested transactions.
So you should keep simple use of it.
The same API can be used to avoid that the user click twice on
a link by setting the 'transaction' attribute at "true" of the <html:link>
tag
the Action called by the link should follow the same process than
SaveSomethingAction

Thanks for your response though!

Not sure if that is a fix, but its a start.

I am amazing that nobody answer you, so i checked the struts exeemple
( file LinkSubscriptionTag )
it appears that you must'n directly call
ActionMessages messages = new ActionMessages();
but yous should use
MessageResources messages =
MessageResources.getMessageResources
("org.apache.struts.webapp.example.ApplicationResources");
I am amazed that nobody answered you ...
so, I will do my best
maybe you should use Action.MESSAGE_KEY instead
ActionMessages.GLOBAL_MESSAGE
it seems it's what it is specified in
http://jakarta.apache.org/struts/userGuide/struts-html.html#messages

will
