Populate too much ...

[Xavier Combelle]

In MyAction1 I set a field of a form MyForm at null.
The I make a forward to MyAction2.
And when MyAction2 read the field, it is set with 
wich were before MyAction1 reseted it.

It seems that is because the struts framework
execute the populate between the MyAction1 and the MyAction2.
So I set the attribute redirect at "true" 
and the field still reseted.

So I'm perfectly happy, my project work, 
but I am still a little bit worried,
Is it really necessary to ask the client
to execute a redirect, since all the treatment
is done on the server side ?


Regards,
Xavier

Maybe you should check if the class you are look for is really in the jar

maybe you should use a form with session scope instead of request scope
so the data edited in the fields which are not in the present form will

I think that all the complex traitment on objects returned by logic

RE: I am seeing double executions of my actions on a single form submit

[Xavier Combelle]

To avoid double post problem,
from a double click of the user or from IE,
you can use the Token functionnality of struts
This functionnality seems not be documented,
but I described it in a previous mail to the mailing list
wih subject :
"Did not found doc about Tokens"

Did not found doc about Tokens

[Xavier Combelle]

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 
tag
the Action called by the link should follow the same process than
SaveSomethingAction

RE: Problems with ActionMessages... (again)

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)

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 ...

RE:

About the reset method, you should know that 
it is called each time your action is called,
before your action is called, just before the
struts framework populate the form with the parameter of the request

but here the problem is that you used


which check in the parameter

instead of 



which should check in the form bean

So in your point of view, a DynaActionForm should be enougth for
any kind of form ?

RE: MVC Design: property in ActionForm or Bean with property in ActionForm ?

[Xavier Combelle]

I have nearly the same think
but I use to create properties as Integer which avoid me
to make a call to Integer.valueOf()

Am I wrong ?

RE: actions only for html:form ?

[Xavier Combelle]

I think you should try something like
loggoff
which call an action without using any form

for the problem of reload page,
i think in the preceding action,
you should save the path in the session scope

Xavier

RE:

[Xavier Combelle]

Maybe your form is in the request scope instead of
session scope ( just set scope to session of the action mappiing
instruts-congig.xml )
So your form settings will be kept between two calls of your page

RE: scope

[Xavier Combelle]

I think you could solve this problem by specifying
in the input attribute af your action the action which populate
the JSP page instead of the JSP page itself
or by putting the first time the bean in session scope

RE: Problem with unicode

[Xavier Combelle]

I think you should use the attribute filter="false" of the write tag
which will disable the character filtering by struts.

see the following adress for more detailed explaination

RE: [Re: [how many form for update and create action ?]]

[Xavier Combelle]

I finaly chose to use the same action and the same form for create and
update.
This decision allow me to simplify my code, but I used two jsp because on
the
specification, the create and the update page are visually different

thanks to all for help me about your advices .

how many form for update and create action ?

[Xavier Combelle]

I have a conceptual problem in my struts application

I am programming an application which give the possibility
to create, update and delete several information, for exemple 
the name and the price of an item.

So I need to give to the user two possibilities :
 1- the possibility to create an item
 2- the possibility to update an item
so i use two action, one for each possibility

Should I use the same form bean to update and create or
should I use different form bean, one for update and one for create ?
and if I should use different form bean, should they have the same type ?

Greetings,

Xavier
