Re: Correct Prepopulate Method (simple problem)
Hi Jack, I have been thinking of posting the same problem but was watching this thread to arrive at something that would help me.. Anyways, as you mentioned in this reply that it can be done using single Action, I am into the same. I want to populate the form using dispatch action. All the things are in place in the framework I am trying to build for one of the project. But somehow I could not digest the idea of having 2 actions to populate the form and do some action. I would like it to be a Single Action using DispatchAction so that all the code related to the single form is kept at one place and is not scattered across the forms. Plz reply back its urgent.

RE: Tiles does not function in case validation error?
Daniel, Why aren't you doing one of the following: 1. set your input from "/ChgPassword.jsp" to the tile "user.chgPassword". 2. change validate="true" to validate="false" then perform the validation call in your Action whenever you need it. That way, you'll know when validation fails and can send the visitor to the "failure" mapping instead of using the action's "input" attribute.

Re: Correct Prepopulate Method (simple problem) SOLVED.
Okay, after some review of my code and such, it is now working! There is not one definite thing, I just double-checked everything I had after taking a break. I want to thank everyone for their input (and patience) and the side emails making sure I was up and running. This is a great community, and even though I'd much rather lurk, the support is great. As Jack suggested, I will move to DispatchActions now, a lot of the work up until now was a proof of concept for Struts/iBATIS to see how they handled CRUD operations. I'm converted. - Nic.

I would not have know this was it. So, your client on a browser is seeing a list of users, chooses a user, then has that users attributes displayed and can update them. Right? If so, this is easy. You can use one JSP page or two for this. Either way it does not matter. I would use one, but you look like you would use two. Let's do that: Let's also use two Actions -- GetUserAction and UpldateUserAction, although I would only use one and would use DispatchAction in some way. But, only use one ActionForm -- UserForm -- which will have a field for identifying the user, e.g. id, and fields for the values your user has, e.g. name, soc_sec_no, etc. Select a user from the first JSP page and call GetUserAction. If successful, the GetUserAction will process the action by getting the User and populating the user's fields in the UserForm, and returning an ActionForward to the second page, where the form values will be displayed. It is that simple. On Mon, 14 Mar 2005 11:53:12 -0800, Nic Werner <[EMAIL PROTECTED]> wrote: I apologize as I seem to have hijacked this thread in a direction I didn't intend. Jack, I didn't mean for you to pick through my code, it was just in response to Joe helping me. To answer your question Dakota Jack, in an overall view what you have said is correct: From a page of Users, I want to click on one to open a JSP page that I can 'Edit' the User attributes, and then have that individual attribute data 'Updated'. It really is very simple. Reading the replies here and the Struts FAQ, everyone says "Create two actions, one to pre-populate the data, and the other to save that data" - So, the first action populates the data in the Execute() function, returns an ActionForward to the 'Edit' JSP. But in order for html:form to display that populated data, I have to refer to the first Action, not the second, barring me from submitting this data to the second page. I've got to have this wrong! I've re-read these responses and pored through my Struts book but I'm obviously missing something Thanks everyone for your input, I only post to the list when I'm truly stumped. - Nic.

Maybe I can do it for you and you can just confirm: You want to have a page with values in a form call an action to "edit" using the values and then to return to some page that will have these values displayed and the page will be used by the client to "update" the data?

Ted's experience mirrors what I see in Struts-based apps in general, but with *lots* of variation in how big the team is before roles become specialized. To some degree, that in turn depends on whether the project team is itself part of a larger organization that has skill specialists available that can work part time on multiple projects, versus a relatively smaller organization that asks their developers to wear multiple hats. The nice thing about a framework like Struts is that it can accomodate any of these working styles fairly gracefully.

Re: Output PDF
Sounds like in 6.0 they went back to sending two extra requests
instead of one extra. I'm assuming this from your statement. I
haven't verified this with our application. The first request (the
one generated by the user to get the PDF) should still have a valid
userAgent (MSIE). The subsequent requests should have the "conType"
userAgent. Can you verify this?

RE: Output PDF
This intrigued me, since our app also has some generated PDFs. Sure
enough, there's a double-get occurring w/ our IE clients (IE 6.0).
Problem is that the "USER_AGENT" header for get #1 & #2 are identical.
In fact, the only difference I can see in all headers is that get #1 has
an "ACCEPT-LANGUAGE" header, whereas get #2 does not. Everything else
is the same
So what gives? Did MS "fix" the wrong end of this bug in IE6? Is it
safe to just look for the existence of the "ACCEPT-LANGUAGE" header?

Subject: Re: Output PDF
I'm assuming that your browser client is IE. If so, the reason your
Action is being called twice is because of a "feature" in IE 4.x+. If
your application returns data that is to be handled with an ActiveX
control (ie Adobe Acrobat Reader) the browser sends additional requests
to the server. In IE 4.x and 5 it actually sends three requests. For
IE 5.5+ it sends two.
Assuming that your using IE 5.5+, the first request is the original
request (duh), but then IE sends a second request to get the
content-type. Who knows why they can't figure this out on the first
request ;) This second request has it's userAgent header set to
"contype". You can solve this problem and increase the performance of
your application by writing a Servlet filter that sits in front of
whatever Actions you have setup to serve PDF content. Have this filter
look at the userAgent header of each request. If it's set to "contype"
just send an an empty response back to the client with the content type
set to "application/pdf". Simple as that.
Now, the reason your getting an exception in the second code snippet you
provided is because after you do your forward the JSP calls
response.getOutputStream(). This is done behind the scenes but you can
see it if you look at your generated Servlet code. This method can only
be called once during the lifestyle of the request, hence your
exception.
It's generally a bad idea to have a JSP produce binary content anyway.
They were designed for Text or HTML output.
I wrote a generic/reusable Servlet whose sole purpose in life is to
write binary content back to a client. I called it BinaryOutputServlet.
You put your binary data (byte[]) and the content type of the data in
the request scope and forward to it. It gets the data and content type
out of the request and writes it back to the client. It can be used for
any type of data this way. I would recommend doing something similar
since Actions are really for control. By writing back to the client
from an Action you are violating the MVC model anyway.
I hope this helps. Oh, and you can read all about the "feature" of IE

Re: Output PDF
Woh! IE *does not* use the URL to determine content type. It's
determined by the MIME type sent back with the response from the
server.
And, by default, the option to have IE save encrypted data to disk is
turned on, so there won't be an issue with PDFs and SSL unless
Micro$oft has changed this is XPSP2. I'm running XPSP2 at home and
have no problem viewing PDFs over an encrypted connection. Micro$oft
would be breaking a lot of clients if they chose to change that
setting.

I'm assuming that your browser client is IE. If so, the reason your
Action is being called twice is because of a "feature" in IE 4.x+. If
your application returns data that is to be handled with an ActiveX
control (ie Adobe Acrobat Reader) the browser sends additional
requests to the server. In IE 4.x and 5 it actually sends three
requests. For IE 5.5+ it sends two.
Assuming that your using IE 5.5+, the first request is the original
request (duh), but then IE sends a second request to get the
content-type. Who knows why they can't figure this out on the first
request ;) This second request has it's userAgent header set to
"contype". You can solve this problem and increase the performance of
your application by writing a Servlet filter that sits in front of
whatever Actions you have setup to serve PDF content. Have this
filter look at the userAgent header of each request. If it's set to
"contype" just send an an empty response back to the client with the
content type set to "application/pdf". Simple as that.
Now, the reason your getting an exception in the second code snippet
you provided is because after you do your forward the JSP calls
response.getOutputStream(). This is done behind the scenes but you
can see it if you look at your generated Servlet code. This method
can only be called once during the lifestyle of the request, hence
your exception.
It's generally a bad idea to have a JSP produce binary content anyway.
They were designed for Text or HTML output.
I wrote a generic/reusable Servlet whose sole purpose in life is to
write binary content back to a client. I called it
BinaryOutputServlet. You put your binary data (byte[]) and the
content type of the data in the request scope and forward to it. It
gets the data and content type out of the request and writes it back
to the client. It can be used for any type of data this way. I would
recommend doing something similar since Actions are really for
control. By writing back to the client from an Action you are
violating the MVC model anyway.
I hope this helps. Oh, and you can read all about the "feature" of IE here:

Re: Output PDF
Why are you doing that in a jsp? You can do it in an action, but it
will not work that well (but it will work better tahn in a jsp, i
promise).
The other issue is that a URL ending in /foo.do?name=value will not be
seen by IE as a pdf. You should probably use a servlet for this
instead, then you can map the URL like the one above as this:
/foo/name/value/file.pdf, that will trick the browser into thinking
that it is just a static file.
Another problem you will have is that if you are using ssl, IE will
not allow acrobat to read from the cache. Your users will have to hack
the registry to make it work.

Re: Correct Prepopulate Method (simple problem)
No problem, Nic. Just trying to see what the problem is. Glad I asked. I would not have know this was it. So, your client on a browser is seeing a list of users, chooses a user, then has that users attributes displayed and can update them. Right? If so, this is easy. You can use one JSP page or two for this. Either way it does not matter. I would use one, but you look like you would use two. Let's do that: Let's also use two Actions -- GetUserAction and UpldateUserAction, although I would only use one and would use DispatchAction in some way. But, only use one ActionForm -- UserForm -- which will have a field for identifying the user, e.g. id, and fields for the values your user has, e.g. name, soc_sec_no, etc. Select a user from the first JSP page and call GetUserAction. If successful, the GetUserAction will process the action by getting the User and populating the user's fields in the UserForm, and returning an ActionForward to the second page, where the form values will be displayed. It is that simple. On Mon, 14 Mar 2005 11:53:12 -0800, Nic Werner <[EMAIL PROTECTED]> wrote: > I apologize as I seem to have hijacked this thread in a direction I > didn't intend.

Re: Output PDF
I'm assuming that your browser client is IE. If so, the reason your
Action is being called twice is because of a "feature" in IE 4.x+. If
your application returns data that is to be handled with an ActiveX
control (ie Adobe Acrobat Reader) the browser sends additional
requests to the server. In IE 4.x and 5 it actually sends three
requests. For IE 5.5+ it sends two.
Assuming that your using IE 5.5+, the first request is the original
request (duh), but then IE sends a second request to get the
content-type. Who knows why they can't figure this out on the first
request ;) This second request has it's userAgent header set to
"contype". You can solve this problem and increase the performance of
your application by writing a Servlet filter that sits in front of
whatever Actions you have setup to serve PDF content. Have this
filter look at the userAgent header of each request. If it's set to
"contype" just send an an empty response back to the client with the
content type set to "application/pdf". Simple as that.
Now, the reason your getting an exception in the second code snippet
you provided is because after you do your forward the JSP calls
response.getOutputStream(). This is done behind the scenes but you
can see it if you look at your generated Servlet code. This method
can only be called once during the lifestyle of the request, hence
your exception.
It's generally a bad idea to have a JSP produce binary content anyway.
They were designed for Text or HTML output.
I wrote a generic/reusable Servlet whose sole purpose in life is to
write binary content back to a client. I called it
BinaryOutputServlet. You put your binary data (byte[]) and the
content type of the data in the request scope and forward to it. It
gets the data and content type out of the request and writes it back
to the client. It can be used for any type of data this way. I would
recommend doing something similar since Actions are really for
control. By writing back to the client from an Action you are
violating the MVC model anyway.
I hope this helps. Oh, and you can read all about the "feature" of IE here:

If both the "pre-populate" action and the "update" action have a reference to the same ActionForm, you should be good to go. (Just be sure to set validate="false" on the "pre-populate" action.) Here's the sequence of events: 1) The Struts RequestProcessor receives a request that it maps to prepopulate.do 2) It sees that prepopulate.do requires a "YourFormBean" object in request scope, so it checks the request. 3) Since at this point, there is none, it creates a new instance of the appropriate ActionForm subclass and saves it in the request 4) Your prepopulate action is called. Since YourFormBean exists, all you have to do is copy the appropriate properties from your model layer into that object. 5) The prepopulate action returns a "success" forward, which points to editYourFormBean.jsp 6) This JSP page has an tag that points to update.do. The form tag class consults the configuration classes and sees that the form for that action is also of type "YourFormBean". Since this form bean already exists, the form fields are populated with those values. Does that help? -- Jeff -- Jeff Beal Webmedx, Inc.

Output PDF
I'm using Jasper to create PDF's through my Actions and cannot figure out a
good way to export the resulting byte[] to the user.
Currently the tail end of my Action class looks like this:
byte[] reportBytes = null;
File jasperReport = new File(location);
try {
reportBytes = JasperRunManager.runReportToPdf(jasperReport.getPath(),
parameters, dataSource);
log.info("Found : " + reportBytes.length);
} catch (JRException e) {
e.printStackTrace();
}
response.setContentType("application/pdf");
response.setContentLength(reportBytes.length);
ServletOutputStream ouputStream = response.getOutputStream();
ouputStream.write(reportBytes, 0, reportBytes.length);
ouputStream.flush();
ouputStream.close();
return(null);
This will display the pdf, but the action class itself somehow get called a
second time as the above log statement is displayed twice.
I also tried to set the byte[] on the request and forward onto another page
which does:
<%
byte[] reportBytes =
(byte[])request.getAttribute("REPORT_BYTES");
response.setContentType("application/pdf");
response.setContentLength(reportBytes.length);
ServletOutputStream ouputStream = response.getOutputStream();
ouputStream.write(reportBytes, 0, reportBytes.length);
ouputStream.flush();
ouputStream.close();
%>
But this complains about: getOutputStream() has already been called for this
response
Any ideas?
Re: Correct Prepopulate Method (simple problem)
I apologize as I seem to have hijacked this thread in a direction I didn't intend. Jack, I didn't mean for you to pick through my code, it was just in response to Joe helping me. To answer your question Dakota Jack, in an overall view what you have said is correct: From a page of Users, I want to click on one to open a JSP page that I can 'Edit' the User attributes, and then have that individual attribute data 'Updated'. It really is very simple. Reading the replies here and the Struts FAQ, everyone says "Create two actions, one to pre-populate the data, and the other to save that data" - So, the first action populates the data in the Execute() function, returns an ActionForward to the 'Edit' JSP. But in order for html:form to display that populated data, I have to refer to the first Action, not the second, barring me from submitting this data to the second page. I've got to have this wrong! I've re-read these responses and pored through my Struts book but I'm obviously missing something Thanks everyone for your input, I only post to the list when I'm truly stumped. - Nic.

Re: RE: Struts - Page Centric Framework[Scanned]
In Struts, the Front Controller and Dispatcher are combined. Which begs the quesion: Do you actually miss a Front Controller, which provides a centralized access point for presentation-tier request handling? Or do you just miss a Dispatcher, which selects the views to handle the response. (Struts comines these into something J2EE Patterns calls "Service to Worker".) Which is to say, do you need to do something special with each request, or is that you just need more help in selecting the response? > I was wondering if any of you knew a Struts like > framework in the .NET world. Maverick has a .NET version of a Struts-like framework, but we haven't been using it. > how do you use ASP.NET? We've been setting our workflows up as panels. One of our pages might have a dozen different panels, which are turned on and off as a client proceeds through a workflow. For the most part, the panel approach lets us get away without a Dispatcher. Pages lead from a main menu down to a mulit-panel work flow, and then back to the main menu. What I started to miss was the centralized Application Controller features of Struts. Features like * command selection * input validation * text formatting * message handling * fault trapping * type conversion * logic processing * control population and harvesting If you think about it, none of these features need to be tied to a particular presentation layer technology. Most of the featuires are found in Struts, and some other frameworks. (I think of Struts as the "unabridged" framework. Many others do what you need, but Struts does it all.) ActionMappings select a command. ActionForm validates input. ActionErrors handles messages. ExceptionHandler catches any runtime faults. BeanUtils converts types and formats text (to a degree). Action processes logic. Taglibs populate controls, and the ActionForms harvest input (using JavaBeans as transfer objects). What we are starting to do is use the inheritence properites of the Page Controller for dispatching, and then calling a Controller from the code-behind. So instead of the Front Controller deciding which Command to call, the code-behind decides for itself which Command it needs to call. We're pushing as much logic up into the Application Controller as we can. We like to test-first, and so we want to test as much of a transaction script as possible before plugging it into the presentation layer. What's left for the Code Behind is bundling up the input, passing it to the appropriate Command, unbundling the output, and then turn on or off the appropriate peansl If you get past the trees, and into the forrest, it's starting to feel a lot like Struts again :) -Ted. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Correct Prepopulate Method
This is where I must be doing something wrong, my UserUpdateAction isn't finding the pre-populated form. Here is my code for both: Hm. is UserUpdateAction expecting certain properties to survive between the requests which are not in the request parameters? By default, form beans have request scope, so a new instance of UserBean is created upon submission to /userUpdate.do and populated with request parameter values. If you want values to be in the UserBean on both requests, you need to include them in the form on UserEdit.jsp, if only as hidden fields. You can add the "scope='session'" attribute to both mappings and then Struts will store the form in the user's session, which would deal with that problem; this method is often used in a "wizard" process where several screens are used to sequentially populate a form without needing to use hidden fields to repeatedly resubmit values. Any chance its something like this?

Is what I am doing calling JSP pages directly? From my struts-config
below I show them being mapped to Actions.
My question was that I have to set the html:form action to be the
calling Action in order to populate it, but I want it to submit to a
different page, and if I follow the Apache struts example as below, it
doesn't follow correctly.
I think I'm missing something. Your struts-config looks fine:
My struts-config:
type="com.racquetclub.action.UserEditAction"
name="user">
type="com.racquetclub.action.UserUpdateAction"
name="user">
So the user goes here:
yourserver/yourCtx/userEdit.do
your UserEditAction executes, and is given an instance of ActionForm
based on the form-bean config with the ID "user". It prepopulates and
delivers to the UserEdit.jsp page.
This page includes a form which looks like this:
...
If I set the html:form to be "userUpdate", I get a blank form back, not
prepopulated. That was my catch, setting it to 'userEdit' gets the right
info in the form, but I need that data to go over to 'userUpdate'.
Isn't this the model? Action A populates Bean, JSP displays it, and JSP
submits to Action B for processing.
When the tag executes, it uses "/userUpdate" to look up an
action mapping, where it finds that it needs an ActionForm linked to
the id "user" for prepopulating its fields. It should find the same
one which was prepopulated, and the fields should be filled according
to what UserEditAction set up.
This is where I must be doing something wrong, my UserUpdateAction isn't
finding the pre-populated form. Here is my code for both:
UserEditAction:
SqlMapClient sqlMap = DatabaseManager.getInstance();
//ActionForm userForm = (ActionForm) form;
try{
UserBean userForm = (UserBean)form;
UserBean user;
user =
(UserBean)sqlMap.queryForObject("selectUser",userForm.getUserId());
BeanUtils.copyProperties(userForm,user);
}
catch (Exception e)
{
e.printStackTrace();
throw new RuntimeException("Error initializing
MyAppSQLConfig class. Cause: " + e);
}
return (mapping.findForward("display"));
-
UserUpdateAction
SqlMapClient sqlMap = DatabaseManager.getInstance();
UserBean userForm = (UserBean)form;
UserBean user;
try{
sqlMap.update("updateUser",userForm);
}
catch (Exception e)
{
e.printStackTrace();
throw new RuntimeException("Error initializing
MyAppSQLConfig class. Cause: " + e);
}
return (mapping.findForward("success"));
When the form submits, it is processed by a different action at a
different path linked to the same form-bean ("user"). You might want
to add "validate='true'" to the "/userUpdate" mapping, unless you're
not performing any validation with Struts.
What isn't working? It sounds like you think your form has to submit
to "/userEdit", but it doesn't, if you have another action mapping
which uses the same ("user") form bean.

Validator Framework question
I am trying to use the validator framework for some simple form-field
validation. Under web-inf, I have placed the default validator-rules.xml
eg:
/WEB-INF/validator-rules.xml (from the extracted examples).
and
/WEB-INF/validation.xml (from the storefront example, see below);
and in my struts-config.xml file I added this:
So it appears I have put the proper pieces in place, but when the webapp
starts-up, I get the below error, which looks like it cannot find the files?
Also, I have validated that the files are not bad xml.
Any ideas?
Thanks,
Scott

Re: Request Processor validation Question
Hi Scott, Check the javadocs for the RequestProcessor. Any method which has an ActionMapping as an argument can be used to figure out the action (ex: mapping.getPath()). If you plan to do authorization the method processRoles() is a good candidate to be overriden. - Original Message - From: "Scott Purcell" To: user@struts.apache.org Subject: Request Processor validation Question Date: Mon, 14 Mar 2005 09:31:35 -0600 > > Hello, > I have extended the RequestProcessor and I am looking for a way to > find out where the page is going to.

Request Processor validation Question
Hello, I have extended the RequestProcessor and I am looking for a way to find out where the page is going to. The reason for this is as follows. I am giving each user a UserObject when they hit the site. Later on, after they log in, I set some flags to know they are valid inside the application. I am just using a boolean "isLoggedIn". Anyway I need a way to find out which Action they are heading to and put some logic in my extended RequestProcessor class, that could check which Action and send them to the login, if an action they want to use is past the login page. If I know the action and they are just logging in, I will not show them a "session expired" flag. But if they are heading for an inside page (a page they need to be logged in for), and the object says "not logged in" then of course, I want to take them to the front door and show a msg stating "session expired.". I have gone through the RequestProcessor docs, but do not see anyway to get the action.? Any ideas. Thanks, Scott

Re: [OT]Pop-Up Window and getParameter()
yes, but you'd need to store all data from a popup window via javascript into your document (web page) OR to have an action inbetween, which is called on pop-up window submit, and stores the values in the session or something for later retrieval. leon On Mon, 2005-03-14 at 06:56 -0800, Caroline Jen wrote: > I have used the getParameter() to retrieve data from > web page text fields.

[OT]Pop-Up Window and getParameter()
I have used the getParameter() to retrieve data from web page text fields. No problem so far. Now, I have a web page that has a number of text fields. In addition, the JavaScript is used in this web page to pop-up another window for users to enter more data in some text fields and a textarea. When uses click on the OK button provided in this pop-up window, it disappears from the screen.

Is what I am doing calling JSP pages directly? From my struts-config

My question was that I have to set the html:form action to be the

different page, and if I follow the Apache struts example as below, it
doesn't follow correctly.
I think I'm missing something. Your struts-config looks fine:
My struts-config:
type="com.racquetclub.action.UserEditAction"
name="user">
type="com.racquetclub.action.UserUpdateAction"
name="user">
So the user goes here:
yourserver/yourCtx/userEdit.do
your UserEditAction executes, and is given an instance of ActionForm
based on the form-bean config with the ID "user". It prepopulates
and delivers to the UserEdit.jsp page.
This page includes a form which looks like this:
...
When the tag executes, it uses "/userUpdate" to look up
an action mapping, where it finds that it needs an ActionForm linked
to the id "user" for prepopulating its fields. It should find the
same one which was prepopulated, and the fields should be filled
according to what UserEditAction set up.
When the form submits, it is processed by a different action at a
different path linked to the same form-bean ("user"). You might want
to add "validate='true'" to the "/userUpdate" mapping, unless you're
not performing any validation with Struts.
What isn't working? It sounds like you think your form has to submit
to "/userEdit", but it doesn't, if you have another action mapping
which uses the same ("user") form bean.

Re: Correct Prepopulate Method
Nic, the pages don't matter in a real sense. Actions process requests using the data from ActionForms and then return an ActionForward. Anytime you want to process a request use them. It is that simple. If you just explain what you want to do, we can give you a dozen ways to do it in all probablility that are easy to follow. Just state what you want to happen from the point of view of the client using the browser or the browser itself. Okay? I promise you that it will be very easy if you state the problem and quit worrying about pages.

Re: session and request scope
Radu. To avoid such problems you may use contextes. When you have contextes stored in the session and you store your values only in this context you have no problem to clean the session. There is a small architecture project called struts-it (struts-it.org) in detail http://plstrutsit.sourceforge.net/architecture/presentation.html, provides such a context. The signature of an execute-method is such as public void execute(Context context); where a context is a commons-chain context. The Request processor has the responsibility to create such contextes and share them over an use-case. This approuch is available for struts 1.2 as well as struts 1.1. I think the struts-chain (1.3) has the same approuch. Dealing witch contextes is quite nice, because you can use this context in the business layer too.

class TagUtils, retrieving a message bundle, code modification re quest
Hello, I've been looking into the source code (of both 1.2.4 and 1.2.6, not cvs), and I have a question about the way a message bundle is looked up based on its name. I understand from the code that the resource bundle is search: - in the page context - if not found, in the request context - if not found, in the application context This process make perfectly sense for me but I'm surprised how the search in the application context is done. From the code, we can see that the bundle is first searched by its name + the module prefix, then by its raw name. I would have done it the other way around, for two reasons: - If I specify in the code the correct bundle name with the module prefix appended, there is an extra search done (the one for "name + module prefix + module prefix") - If I have two resources bundles, one in the default module, one in a module "foo", with the same name in the config file, let's say for pictures (so it would be called "ImagesResources"). If I am in the module foo, I can't get access to the bundle "ImageResources" of the default module because it will always find the bundle "ImagesResources/foo" first. Before proposing reporting anything in bugzilla, I would like to know the opinion of the community on this issue (assuming that I managed to make it clear): should the lookup in application context be done first by raw name or by "name + module prefix"?
