RE: passing object in request from jsp to action
Due to the nature of HTTP, you cannot pass an object from the client's browser to the Action. Instead you either need to a. pass the form fields/request parameters you need to build your object again or b. store the Object in the session so you can retrieve it when the Action is called.

RE: DynaValidatorForm and Checkbox
Having never used DynaValidatorForm before, I'm not 100% sure what
the means for accessing the properties would be. It's clear that
getCatalogID() is not going to be defined on DynaValidatorForm
as an available method. So I'd try calling getDynaProperty() and
if that doesn't work you should research further into how DynaForms
operate.
Sorry for the limited reply, but maybe it will help anyway.

Subject: RE: DynaValidatorForm and Checkbox
Ok,
making headway but have issue:
Since it is a single checkbox, I am using a Boolean, so here
is my bean:
form-bean name=covers
type=org.apache.struts.validator.DynaValidatorForm
form-property name=covers type=java.lang.Boolean
form-property name=catalogID type=java.lang.String
/form-bean
Now when the user submits the form, there will be a catalogID set.
So I am trying to pull out the catalogID like this in my Action class:
public ActionForward executeAction(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response,
AppObject appObject,
UserObject user)
throws Exception {
DynaValidatorForm theForm = (DynaValidatorForm)form;
String catalogID = theForm.getCatalogID();
Boolean checkbox = theForm.getCovers();
But it will not compile. How do I get the values from the
form? I usually create my own physical bean.
Thanks,
Scott

I have a couple of jsp pages where there is a single
checkbox on the page.
But as a newbie, I am not sure what type in the creation to
make it? A
String? A Boolean?
I usually use Boolean for checkboxes. (Read the docs about using the
'reset' method to make 'un-checking' the box possible.)
If it's a yes/no question, I sometimes use a pair of radio
buttons for Y
or N.

RE: bean in a Actionform
Hello Temp, It seems like you want to use a combination of the nested bean property naming and list-backed properties. I think your property name in the form element will be something like mybean.prop which will result in form.getMybean().setProp() when the form is submitted. I believe your setProp() should accept a String[] (array) rather than just a single String. Each of the items that is selected will be passed into setProp() inside this array. You may need to name your method setProps() (notice the 's' in the name) -- I'm not totally sure.

RE: DynaValidationForm Display In JSP?
Wow. I'm stumped. As I said, I don't have firsthand experience with DynaForms... Only thing I can think of is, did you set the input to your JSP correctly in the struts-config? Not to sound overly optimistic, but it's GOT to work. It uses the same functionality on the sending as it does when setting up the JSP, it's not like it's a separate (difficult) problem to solve. Maybe double-check your get() method to make sure it matches your set() as far as return type etc.? What exactly is the error you get when the JSP blows up? -Original Message- From: Scott Purcell [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 30, 2005 1:04 PM To: user@struts.apache.org Subject: DynaValidationForm Display In JSP?

Since it is a single checkbox, I figured I would throw this into the JSP page, and let it set checked or unchecked depending upon the form value.

RE: Place message in jsp from action?
Just having learned this last week, it's fresh in my mind. Looks like you are missing the call to this.saveErrors(errors); this puts the ActionErrors into the request for your JSP to display. The other thing I'd say is that ActionErrors is deprecated; you might use ActionMessages instead, which works EXACTLY the same way. Then you would use this.saveMessages(messages); Good luck, Mike PS - not sure you need to get the MessageResources explicitly -- maybe that's used by other code further down your class? -Original Message- From: Scott Purcell [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 23, 2005 5:25 PM To: user@struts.apache.org Subject: Place message in jsp from action?

RE: Displaying a HashMap as a select
Note that there's also the java.util.LinkedHashMap which will maintain whichever order you insert the values in. This gives you the consistency of TreeMap without the overhead of resorting, if your data is already sorted when you're populating the Map. It also has a funky LRU-style option that orders the items based on which ones have been most recently accessed, but I've never used that. I've found LinkedHashMap to be indispensible, and the performance is good according to the Javadoc. hth, Mike -Original Message- From: Jeff Beal [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 08, 2005 9:34 AM To: Struts Users Mailing List; [EMAIL PROTECTED] Subject: Re: Displaying a HashMap as a select Even if the results coming out of the database are sorted, throwing them into a non-sorted Collection, like a basic HashMap, will un-sort them.

RE: map-backed forms with multibox/multiselect lists?
The good news is that this DOES work.
I simply declared my methods to be
public void setFoo(String key, String[] foos)
{
...
}
public String[] getFoo(String key)
{
...
}
and everything works fine. It took a detour through the Struts
source (and ultimately from there through the beanutils source)
to figure this out, but the problem was essentially that when
doing the bean introspection, the beanutils first finds the getFoo()
method and stores its return type. It then looks for a setFoo()
method with the same argument type as the return type of getFoo().
If you try to return foo as an Object, it just won't work -- your
setter won't be found and the method will never be called.
thanks for the input,
Mike

Subject: RE: map-backed forms with multibox/multiselect lists?
I had the same problem some time ago (the solution vaguely
suggested by
Jack wouldn't had been an option since the properties were
dynamic so I
needed the key to distinguish between them). I asked on this
list for help
at that time, but didn't got an answer, so I guess nobody
succeeded in
doing something like this. Therefore I had to find some other
solution to
my problem...
I'm guessing this might be some sort of a problem with
commons-binutils
(although public void setFoos(String key, String[] foos)
isn't a valid
javabeans setter so maybe it's just a bit out of it's scope).
