[S2] How to get the requested path from an interceptor
Is it possible to get the requested path from inside an interceptor? For instance, the following url was requested: http://myhost:8080/mywebapp/private/admin/json/companies.action So, from the interceptor, how can I get the /private/admin/json/companies.action part from that url? I searched across the ActionInvocation object but could not come with a solution. Regards, Célio - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: How to use the s:param tag with s:textfield?
I have the same problem, but as far as I could see, formatting support
in S2 is nasty. You can format something with s:text using the
format defined in your resource bundle, but you can't do that with
s:textfield. WTF?! Man, so far I've spent 3 hours trying to do make
that work, but just couldn't. I'm going crazy! Serious...

[S2] Incorrect validation behaviour
I have a couple of actions with validation configuration. The
validation works fine for most of them, except for one in which case
all the fields are always invalidated even when I fill them correctly.
Also, I noticed that, after submitting the form, the values of the
fields are not preserved. I can't understand why it doesn't work
right, because I simply copied and pasted from existing files of
another action. I've already spent hours trying to fix that, but can't
figure out what's wrong.

[S2] How to get an object from Spring inside an interceptor
Hi, I want to implement an OpenInView pattern interceptor involving Hibernate, but there's a problem. My SessionFactory is both created and managed by Spring, and my interceptor should have access to that SessionFactory, however I don't know how to do that. I have already searched a lot the web and the docs but couldn't find an answer. Does anybody know if that's possible (and how)?. Regards, Célio. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [S2] How to get an object from Spring inside an interceptor
2007/5/23, Guillaume Carré [EMAIL PROTECTED]:
if your SessionFactory is injected in your action, and all your
actions extend AbstractAction for example, that has a
getSessionFactory() method, you can do this:
public String intercept(ActionInvocation invocation) throws Exception {
Action action = (Action) invocation.getAction();
if (action instanceof AbstractAction) {
sessionFactory = ((AbstractAction) action).getSessionFactory();
...
}
The actions are unaware of any Hibernate type. This is mandatory
since I don't want my actions to depend on a specific persistence
mechanism. They only see DAO interfaces (which are also not dependent
on any persistence mechanism).
Thanks,
Célio.

[S2] Validation error messages are not being cleared
An action has this validation config:
validators
field name=nome
field-validator type=requiredstring
messageCampo obrigatório/message
/field-validator
/field
field name=identificacao
field-validator type=requiredstring
messageCampo obrigatório/message
/field-validator
field-validator type=regex
param name=expression[a-z]+/param
message
Digite apenas letras minúsculas. Não são
permitidos espaços,
números, nem caracteres acentuados.
/message
/field-validator
/field
/validators
The validation works fine, except that the field error messages are
not getting cleared when the user fills the fields correctly in the
second submit.
The procedure is:
1. Submit the form with all fields empty;
(Struts shows the validation error messages correctly.)
2. Fill all fields with good values and submit again.
(Struts duplicates the messages right above the previous ones.)
And as you submit the form over and over again, Struts keeps
invalidating the fields, duplicating the error messages. I'm using
Struts 2.0.6.

How do I implement client-side validation code for a custom validator?

How to dinamically load a select field
Well, perhaps dinamically is not the best way to describe it, but anyway what I need is to load a select field based on the value selected on another select field. Let's say you have a State field and also a City field. The user selects a state and the cities of that state are loaded in the City field. What's the best way to do that without having a page refresh? Regards, Célio. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Make Struts set form data onto the action in same order as the form's fields
Struts don't set the form data onto the Action in the same order in
which the fields appear in the form. For instance, suppose you have a
form like this:
s:form action=customer!save
s:token/
s:hidden name=id value=%{id}/
s:textfield name=customer.name label=Name size=30
maxlength=200/
s:textfield name=customer.phoneNumber label=Phone size=14
maxlength=14/
!-- ... and whatever a zillion fields more --
/s:form
And its corresponding Action, which is something like:
public class CustomerAction extends ActionSupport {
private int id = 0;
private Customer customer;
private CustomerDao dao;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Customer getCustomer() {
if (customer == null)
customer = id != 0 ? dao.get(id) : new Customer();
return customer;
}
public String input() throws Exception {
if (getCustomer() == null)
return ERROR;
return INPUT;
}
public String save() throws Exception {
if (getCustomer() == null)
return ERROR;
dao.save(getCustomer());
return SUCCESS;
}
}
You could expected that Struts, when submitting the form, would first
set the id, then customer.name, then finally custumer.phoneNumber.
However, it does not follow that order; actually, it does set the data
in random order. In this case, the order is important because, if the
user is altering an existing customer, its id must be set before
getCustomer() gets invoked. Otherwise, the action will create a new
customer with zeroed id.
The way I built both the action and the view prevents me from writing
a lot of extra code (like getters and setters for each of the form's
field), and that's why I would like to know whether there's a way to
make Struts follow the fields' ordering when submitting the data into
the action. And if there's not, may the Struts dev team implement
that, if possible.
Regards,
Célio.

Re: Make Struts set form data onto the action in same order as the form's fields
2007/1/25, Dave Newton [EMAIL PROTECTED]: From my point of view it seems like your implementation is broken: if you need to create a Customer from an ID passed via a form or URL then you either need to implement Preparable or do the DAO operations in the (in your case) input or save methods. The DAO operations already do that. The problem happens when the user is *altering* an existing customer (creating a new customer works fine), more specifically when the user is submitting changes from the form to an existing customer object (alongside with an existing id); in that case, the id must be set before getCustomer() is called, otherwise a new customer will be created with zero id. Loading the form with an existing customer works fine. Submitting changes to it is where the problem resides. The idea behind getCustomer() is to abstract the retrieving of the customer object wherever it's called along the action's code so that I don't have to care about whether it's an existing customer or not. Implementing Preparable does not seem to solve the problem because the parameters are set before the prepare() method is invoked.

Re: Make Struts set form data onto the action in same order as the form's fields
2007/1/25, Tom Schneider [EMAIL PROTECTED]: This is an issue with the typical edit/save scenario. The problem we are discussing is that the domain model is needed in some form before the parameter can be repopulated from the form save. The technique you are using is to reread the data from the database before the parameters are set. An alternative technique would be to put the domain model into a place in the session--so on the save, you can retrieve the the model from the session and then allow the parameters interceptor to populate the new data. (This is referred to as detached objects in the Hibernate world) The advantage of putting the model in the session is that if some else modifies the data before you reread the data, but after you have displayed the edit page, you will not have the original model. This particularly a problem with a model where you are dealing with lists of domain objects. In this case, the edit will fail because you will be trying to set parameters on items that might not exist anymore. (Or you've pulled in data that the user doesn't know about) Therefore the safer technique is to save off the model. If you're concerned about putting too much into the session, you can store the data in a cache, such as ehcache, that will store items to disk if there are too many things in memory. (This is the technique that we used--we called it a model repository and we created a couple different implementations) I would love to see something like this out-of-the-box with struts2, but nothing currently exists. Thanks, I really appreciate your suggestions. However, I prefer a stateless approach because (I think) it helps to keep things simple in this case. Using some kind of cache between page requests is more like a stateful approach that I would like to avoid here for simplicity reasons. Well, having Struts passing parameters in the order defined by the html form would solve my problem. :-) Regards, Célio. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Make Struts set form data onto the action in same order as the form's fields
2007/1/25, Tom Schneider [EMAIL PROTECTED]: Unfortunately I don't think that's possible. The parameters get put into a map structure, so the original parameter order is lost by the time it gets to the servlet API. We've run into several instances where something will work on one app server, but break on another because we had duplicate parameters on the url--so depending on how the app server handled it, we would get one or the other value. I can't imagine that any java web framework could do this successfully. That's sad! :-( Célio. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: preInvokeJS does not work for a tag
Hi Musachy,
2007/1/2, Musachy Barroso [EMAIL PROTECTED]:
What version are you using? using head svn , I modified showcase's
remote link first example to this:
s:a
theme=ajax
href=%{ajaxTest}
indicator=indicator
targets=t1,t2 notifyTopics=/after
preInvokeJS=alert('test')Update 'Div 1' and 'Div 2', publish topic
'/after', use indicator/s:a
and it shows test. preInvokeJS is deprecated. If you are using head
svn, use notifyTopics instead. See showcase for examples, or this link:
http://struts.apache.org/2.x/docs/ajax-tags.html
I don't know much about ajax (well, almost nothing), but using the
ajax theme in my case is not a kludge?

preInvokeJS does not work for a tag
Hi,
The preInvokeJS attribute does not work for the a tag as described
in the example from http://struts.apache.org/2.x/docs/a.html. That
feature seems to be originated from the issue
http://issues.apache.org/struts/browse/WW-912. Below is a snippet of
my source JSP code.
s:a href=%{delete} preInvokeJS=confirm('%{getText('confirm-delete')}')
s:text name=record.delete/
/s:a
The anchor works properly, except that it does not call the confirm()
method. The generated HTML gives me this code:
a href=/sed/listUsers!delete.do?id=1Deletar/a
And there's no occurrence of the word confirm in the whole HTML code
nor there's any reference to an external JS file.
I presume I'm not missing anything. Any guess whether this feature is
actually working or not?

Values of multiple select tag are not being selected
Given the following code:
myPage.jsp:
s:select name=selectedRoles list=allRoles listKey=id
listValue=name multiple=true
label=%{getText('roles')}/s:select
MyAction.java:
public SetString getSelectedRoles() {
SetString ids = new HashSetString();
for (Role role : selectedRoles)
ids.add(Integer.toString(role.getId()));
return ids;
}
public ListRole getAllRoles() {
return roleDao.list();
}
All the available roles are properly loaded to the list but the ones
returned by getSelectedRoles() are not appearing selected in the list.
I have compared my code against the Employees Manager's (from
struts2-showcase-2.0.1) and my code seems to be correct. In addition,
I debugged getSelectedRoles() to check if the selected role ids are
being correctly returned, and they actually are.
I can't catch anything wrong in my code. Could anybody help me on this?

Célio.
