validator + pre processing before foward
Hi all, I am using struts validator. I have a form that needs a object in the request to populate some bean:write outputs and some form input elements values. When I submit this form to an action mapping that has validate=true and the validation is not successfull, the user returns to the original page with the form, but my object is not in the request anymore, naturally. Is there a way to use validator and still be able to set a object in the request (or do something) before the user is forwarded to getInputForward()?? For now, I have disabled validator for this action and I am validating inside my action execute() method. (I use dyna action forms, that´s why I don´t use form.validate() ). Any suggestion?? tks Felipe - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
client side validation - DynaValidatorActionForm
Hi,
I have a Form Bean of type DynaValidatorActionForm that is shared among
multiple actions.
I set validation.xml with something like the code bellow. But when I tried
to enable client side validation placing html:javascript and adding onsubmit
to html:form I can´t get it to work
What I see is that having strus-config´s action-mapping´s path in the name
attribute of validation.xml form element, it causes the javascript validate
function to be created as something with / character in the middle,
causing the problem.
Am I doing something wrong??
validation.xml:
formset
form name=/createAddress
field property=city depends=required
arg0 key=prompt.city/
/field
/form
...
/formset
Javascript generated by Validator:
script type=text/javascript language=Javascript1.1
!-- Begin
var bCancel = false;
function validate/createAddress(form) {
if (bCancel)
return true;
else
return validateRequired(form);
}
...
html:form :
. onsubmit=return validate/createAddress(this)

RES: from Action to Facade: simple attributes or Business Objects
Tks for the reply Tim.
I now see the advantages of my latter case.
But being my form bean a DynaActionForm, can I still use
BeanUtils.populate()??
If not, what would be the alternative?
Tks
Felipe

Assunto: RE: from Action to Facade: simple attributes or Business
Objects
The philosphy is that the Actions (controller) move bean properties
from form bean(s) into business beans, and pass the business bean into a
business object to perform an operation. I.e., the action should
contain all of (and only) the web-specific portion of the application.
I.e., the latter case in your example. Think about what happens if you
add a property? How many places do you need to change it? One less (at
least) in the patter case. You can (typically) use BeanUtils.populate()
do move all properties in one fell swoop.

Hi,
I was wondering what do experts recommend:
inside Action´s execute method we should pass the attributes
to the Facade or create the business objects in the Action
and pass them on?
1)
execute(){
Facade.addUser(name, surname, login, birth, );
}
or
2)

I need to check the Session for an authenticated user before

To do this I subclassed ActionServlet and only call

if (request.getRequestURI().endsWith(welcome.do) |

else if (request.getSession().getAttribute(USER) == null)

}
I also know about the ability to subclass the RequestProcessor
and
providing my own implementation of the processPreprocess method
to
accomplish the same thing.
Does anybody know of any serious disadvantages or side effects
of
subclassing the ActionServlet class rather than the

This way you can't extend other 'struts core actions' (Dispatch,
Lookup...).
I think a better way may be:
- Using a filter (servlet 2.3) in order to pre and post process the
request
- Extending RequestDispatcher
Regards,
Guido.
PD. I am not sure, but i think you can find a discussion about that in
Struts in Action.

Basically subbody1 2 are just extra tiles? Try this - your tiles-defs.xml:
definition name=tile.foo extends=mainTemplate
put name=body value=/foo.jsp /
put name=subbody1 value=/foo2.jsp /
put name=subbody2 value=/minifoo.jsp /
/definition
in your mainTemplate.jsp, you would have:
tiles:get name=body
put name=subbody1 beanName=subbody1/
put name=subbody2 beanName=subbody2/
/tiles:get
in your foo.jsp you would have:
tiles:insert attribute=subbody1 /
I haven't actually done tiles to 3 levels deep, just 2, but I've never
heard of any problems with it.
