JSTL formatNumber and Locale
Hello,
I use the following syntax into a jsp page:
fmt_rt:formatNumber groupingUsed=true var=minInc scope=page
minFractionDigits=1 maxFractionDigits=1
value=${scenarioForm.minIncome}/
nested:text property=minIncome value=${minInc} /
The minIncome is initially defined into the scenarioForm as something
similar to an ordinary double, i.e. 2.0
The double is displayed into the minIncome text field as 2,0
accordingly to my regional settings. Ok
When the action defined for this form is executed the form minIncome
property value is converted to a numeric format. Ok
But... when I submit the form the validate() method is executed. If it
returns some errors, the request is redirected to the original page
before any regional-to-numeric conversion is performed, so now the
formatNumber tag doesn't like the format of the minIncome property:
2006-04-19 09:29:45,967 [http-0.0.0.0-8080-1] ERROR [ROM] [USER:
tremal] javax.servlet.jsp.JspException: In lt;formatNumbergt;, value
attribute can not be parsed into java.lang.Number: 2,0
How can I solve this? I would immediately convert the value in the
scenarioForm.setMinincome() method, if the http request object was
somehow available, as this method is called before the validate().
Infact, I need to know the user Locale to parse the string to a number
correctly (do I?). I may convert the value in the validate() itself
before proceeding with the validations, but I don't like this
solution, as it's advised against performing other than simple
validation in that. I may define an additional form field with the
user locale read from the request, but I'd rather use a smarter
solution.
Any suggestions?

Re: Can struts do it?
2006/4/21, Marco Mistroni [EMAIL PROTECTED]:
I have a DynaActionForm. It has two array fields (String[] ownerRef and
Boolean[] suspendPart) and some other fields. I want to populate these
arrays from a form and be able to submit the value from the page.
That's it.
why don't you define an array of beans, each of which containing two properties:
class myBean{
}

class myBean{
String ownerRef;
Boolean suspendPart;
// getters and setters ...
}
Than you may add an array property to your form:
myBean[] simpleIterate
Iterating through this array, reading and setting properties would be
much easier.
In your business logic then, you may populate the original arrays

Re: sslext
2005/12/6, Jim Reynolds [EMAIL PROTECTED]: If I put a object into the request, and switched protocols, the request object was no longer found? Since most struts work has I see that when sslext switches from a protocol to another what is really happening is: a redirect is sent in the response to the user. So the client performs another request with the swapped protocol. So: 1-The client send a request with the first protocol 2-The server send a redirect to the client 3-The client sends a new request with the second protocol The original request is lost in 2, so if you put something in the request before 2, that may be lost as well. I said 'may' because, if I remeber well, sslext itself saves the request object in the session and when the new user request arrives restores the old request appending it as a query string on the new one. This is a behaviour not always good if you are coming out from a secure page (as may be the case when you perform a login) because I noticed that sometimes, exiting from a secure login session, you can see the username and password in the browser url. I resolve it with an addictional redirect (using a JSP forwarding to another, but there are many ways) to clean the request query string before leaving a secure channel. Even if sometimes the usage of sslext is a bit tricky, I think it works well for many things and I use it in my commercial applications. -- TREMALNAIK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
nesting radio buttons
Hello, I'm trying to render a questionnaire on a page using radio buttons. The questionnaire is built as a list of questions, each with some answers the user may check using radio buttons. input type=radio name=question1 value=1 input type=radio name=question1 value=2 input type=radio name=question1 value=3 . input type=radio name=question2 value=1 input type=radio name=question2 value=2 input type=radio name=question2 value=3 My form has an ArryList property, populated with QuestionBean beans which have a property that is an ArrayList of AnswerBean beans. I'm trying to populate the page with a sintax of the form: nested:iterate property=questions nested:message property=questionLabel/ ... nested:iterate property=answers html:radio idName=answers value=value property=question / /nested:iterate /nested:iterate I was not able to find the correct syntax. If i ue the html:radio tag I'm not able to set an indexed radio name, if I use the nested:radio / I'm not able to set a value for the 'value' attribute other than a costant. How did you solve this problem? Any hint would be appreciated thanks, -- TREMALNAIK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Forwarding to the previous page
Hi, I have a menu on my application, which is tiled in all the pages. I have an action of the menu which is common to all the page in which I am, so the execute() method of the action class associated to it must return a forward to the page which called it. I know how to map the forward of an action to a specific, struts-config hard-coded page. How can I deal with this kind of dynamic forwarding? Id est forwarding the action to the page which called it?

Re: Forwarding to the previous page
2005/9/7, Duane Rosengartner [EMAIL PROTECTED]:
This works very well for me.
a class=button href=javascript:history.back()Back/a
aehm,probabily I didn't explain well my problem: I don't have to get
back to the previous page from the actual. Look at this code:
public class DisplayAboutAction extends Action
{
public ActionForward execute(ActionMapping actionMapping,
ActionForm actionForm,
HttpServletRequest httpServletRequest, HttpServletResponse
httpServletResponse)
{
// do stuff.
ActionForward af = new ActionForward();
af.setPath(previousPagePath);
return af;
}
}
I need to get a value for 'previousPagePath'.
I'm trying something like :
bean:page id=reqq property=request /
html:link action=next.do paramId=old_page paramName=reqq
paramProperty=servletPath
but I'm using Tiles, so what I have as 'old_page' parameter is not the
action 'previous.do' but '/jsplayout.jsp' instead
thanks,

Re: Forwarding to the previous page
2005/9/7, Frank W. Zammetti [EMAIL PROTECTED]: I don't think there's anything inherently in Struts to do that, however, it shouldn't be too hard to do on your own... how about this right before you return your ActionForward from ANY Action: session.setAttribute(previousPage, mapping.getPath()); I was thinking of a navigation bean to store in the user session, but is that 'modifying ANY action' that I was trying to get rid of. thanks -- TREMALNAIK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: logout problem
2005/9/5, Adam Hardy [EMAIL PROTECTED]: Fourthly I think the work involved in making something track all sessions like this and then inactivate any that stop would be considerable. At least I can't think of a suitable algorithm off the top of my head. I had the same problem: avoiding duplicate user login and at the same time giving the user the possibility to log again in case of browser/network failure without waiting cache/session timeout. I solved redirecting the user to a new login page, if she tries to relogin while a session is still alive. So it's up user responsability deciding to force out the old session. She should know if he's kicking out his boss ;) -- TREMALNAIK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: showing nested collections in a JSP
2005/8/17, [EMAIL PROTECTED] [EMAIL PROTECTED]: I think I can figure out how to display the tables using the nested:XX tags, but cant figure out how to display the nested collection by radio button. I guess I need to understand how to index a collection dynamiclly. I know JSTL is the preferred way, but I'm stuck with only the struts tags to build Don't know if I undeerstood well your need, but I would use client logic, as javascript functions, to realize this behaviour. Why don't make use of the 'style' property of visual elements to hide/display them depending on radio button clicking events? -- TREMALNAIK - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
