CheckBox and Boolean[] Array - Incorrect Values Submitted When CheckBox is unchecked
Hi, I'm trying to iterate through a Boolean Array using logic:iterate and then display these as check boxes. This works fine, but when submitting the form and resending the Boolean Array back to the Action class, only the values that are true are returned. In the struts documentation it says: WARNING: In order to correctly recognize unchecked checkboxes, the ActionForm bean associated with this form must include a statement setting the corresponding boolean property to false in the reset() method. But this only implies for a single property. Is there a workaround or a fix for this? My jsp code: logic:iterate id=flag name=myForm property=flags logic:equal name= flag value=true input type=checkbox id=flags name=flags value=on checked=checked /logic:equal logic:notEqual name= flag value=true input type=checkbox id=flags name=flags value=on /logic:notEqual /logic:iterate Cheers, Chico. -- The content of this e-mail is confidential, may contain privileged material and is intended solely for the recipient(s) named above.

If that is the case, then why does it work with single boolean properties? I only get this problem when working with an array.

RE: CheckBox and Boolean[] Array - Incorrect Values Submitted Whe n CheckBox is unchecked
Yeah of course I gotcha now ... Cheers chico -Original Message- From: Galbreath, Mark [mailto:[EMAIL PROTECTED]] Sent: 04 October 2002 13:26 To: 'Struts Users Mailing List' Subject: RE: CheckBox and Boolean[] Array - Incorrect Values Submitted Whe n CheckBox is unchecked I'm not sure what you mean. If a checkbox or radio button is not checked, it has NO state. This means boolean false is never passed. Only boolean trues are passed in the request object. If you are defining individual objects as boolean in your ActionForm, the JVM assigns their state to false by default, so any individual object that is passed in the request object will be true and change the state accordingly. It may look like your form is setting your ActionForm booleans to false, but it is not - the JVM is. This is why it won't work with an array - the JVM sets arrays to null by default.

The reason for this is that the html spec in all its gory... uh I mean glory... has in its infinite wisdom defined that a checkbox ( radio button I think) that has not been ticked will not submit any value to the server.

There seems to be two main answers: 1 - do not use so many tags. 2 - find an Servlet Container that will handle tags in a speedy manner. Have I missed any? As for answer one - I am currently beginning the design stage of a project that will use struts ( our first one) and am looking forward to finding tags that clean up my code. I could probably get away with not using the bean write tags for all my labels but I am experimenting with the format attribute for currency and dates ect. It seems that fifty tags is a number that comes up from time to time. How does looping over tags factor into this? As for answer two: - Craig mentioned in this post that the nightly build of tomcat handles this much better. The nightly build thing will be a tough sell for me. Is there a particular production container that (at this time) is known for it's efficient tag handling (code generation, pooling ect) ? Summary: We are doing an internal A/R application. If you include labels, it is not hard to exceed 50 tags. I would be disappointed to find out that I cannot make use of the full power of Struts, and have to replace some tags with a scriplets. But at the same time I would like to know of some of these issues that I might face. Thanks.

We have hundreds of this tag in our page (it's a really complex page I assure you). Drilling down again to find the root cause I found the problem was that bean:write tags call request.getLocale(). request.getLocale(), for some reason we couldn't fathom, took ages to execute.

Populating complex java objects in forms
Hi, If I've got a complex java object (i.e Customer) in the Form class, I can then read off this object in the jsp page, but when submitting to the Action class the Customer object is null. The jsp would look like: html:form action=/updateCustomer Customer Name: html:text property=customer.name/ br a href=javascript:document.forms[0].submit();Update Customer/a /html:form So this would display the current customer name, but if I change the customer name and then hit the submit link, I find the customer instance is now null in the updateCustomer action class.

Hi, I'm trying to find the best way in struts of passing a collection of new values to an action class, but there doesn't seem to be an easy way of doing this ... Here's a given scenario: got a form with an arraylist. in the jsp do a logic:iterate within a html:form tag, and within the iterate tag do a html:hidden property=myArrayListElement value=0/ when I then invoke the action class, I would expect that my arraylist would then have multiple values of 0, but instead it's null. Similar sort of thing happens with string arrays ... so am I correct in saying that struts populates single form elements (like strings), but does not populate collections? At the moment I have to have a hidden String element, which when I submit the form, I have to manually populate this string with the collection values, and comma separate them. This seems a lot of work to do something so simple. Does anyone know of an easier way round this?

RE: Passing a collection (ArrayList or string array) to the Action cl ass from the jsp page ...
Just found out where the problem lies ;) The following does not work: % int i=0;% logic:iterate id=myElement name=myForm property= myArrayList html:hidden name=myElement value=%=new Integer(i).toString()%/ %i++;% /logic:iterate But the following does: % int i=0;% logic:iterate id=myElement name=myForm property=myArrayList html:hidden property=myArrayList value=%=new Integer(i).toString()%/ %i++;% /logic:iterate So the problem seems that you must specify the html element tag with the collection name, and not reference it to the iteration element. Maybe the struts documentation should be updated to clarify this situation.

RE: Java Trivia
Java does have pointers, it is just hidden from the developer! And if you are passing objects around it depends if they are mutable or not. For instance if you pass a primitive value in a method and then change its value, it's only changed inside that method call cause primitives are immutable. The same thing for Strings because they are immutable, you cannot change the contents of the string once been set. But for instance for StringBuffer it is not the case because they are mutable, the same which vectors and so on. If you want a separate copy of that instance you must use the clone method. Therefore if you pass a Vector in a method and then change it inside that method, it will have changed the instance you passed in.

HTML Base Tag using SSL
We have a problem using the html:base tag when displaying a Struts JSP Page under SSL. SSL is configured on our web server (BEA WebLogic) to listen on the default port (443). When the JSP page is displayed in the browser the source HTML code shows the base tag with port 80 instead of port 443 (or blank). If we change the web server configuration so that SSL is listening on a different port (eg. 7002) then the base tag is correctly rendered with :7002. The problem may be arising because when we try to set the URL with :443 in the address the browser automatically removes the :443 and it looks like the html:base tag assumes SSL is on port 80 when it resolves it.

Trying to set the output from jsp page into GZIP format ...
Has anyone tried this?
In the servlet you can simply do the following:
PrintWriter out;
boolean supportCompression = false;
if (request instanceof HttpServletRequest) {
Enumeration e =
((HttpServletRequest)request).getHeaders(Accept-Encoding);
while (e.hasMoreElements()) {
String name = (String)e.nextElement();
if (name.indexOf(gzip) != -1) {
supportCompression = true;
}
}
}
if (!supportCompression) {
System.out.println(-- NOT
COMPRESSING);
out.getWriter();
}
else {
System.out.println(--
COMPRESSING);
if (response instanceof HttpServletResponse) {
OutputStream out1 = response.getOutputStream();
out = new PrintWriter(new GZIPOutputStream(out1), false));
response.setHeader(Content-Encoding, gzip);
}
}
But because I'm using struts, changing the JSP page into a servlet will b
difficult if not impossible.
Does anyone know of another way around this?
cheers,
Chico.

RE: Logic-Iterate not finding scope of Bean
you can also have two separate action classes that use the same form, where you use the first action class when you first go into that page, then use the second when you are submitting or whatever in the form -Original Message- From: Luna, Kat [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 07, 2001 7:58 PM To: [EMAIL PROTECTED] Subject: Logic-Iterate not finding scope of Bean Hi all, me again with my afternoon question.. I have a UserAction class that extracts a list of Users from the database and stores them in an ArrayList. Success from this Action forwards to user.jsp which I want to display the list in table format. I have: %@ page language=java % %@ taglib uri=/WEB-INF/struts-logic.tld prefix=logic % %@ taglib uri=/WEB-INF/struts-bean.tld prefix=bean % html:html headtitle/title /head body table logic:iterate id=user name=UserAction property=userList type=com.test.User TR TDbean:write name=user property=username//TD TDbean:write name=user property=password//TD /TR /logic:iterate ..etc but this causes the UserAction to run again (essentially calling the database and building the ArrayList again). Is there a way to have this bean init() when the jsp page loads and then iterate through the ArrayList instead of calling the Action first and then displaying the page? And if so, do I need to add anything to struts-config.xml to tell the page where to find/identify the UserAction bean?

displaying html errors in order
i can display errors fine, but they are displayed not in the same order as i created them ... I see this is because the ActionErrors class uses a HashMap and therefore doesn't return them in a given order (i think it sorts them according to the hashcode value). I can use the property tag in html:errors tag to display each error individually, but then it displays my error header and footer for each error displayed ...
