RE: Question on the ActionForm design for dynamic data?
Title: Question on the ActionForm design for dynamic data?
I have
been struggling with this problem for a while.
I used
the way Jeff recommended and made the application working, however, because I am
not using the struts taglib displaying the collection data, there is no sense to
put that collection in the form. So I do validation and populating
the session data in the action. I don't like that. I am pretty much
sure there should be a way to use nested form in struts. So that I can use
something like following to display the contributors:
"/>
I
tried couple of ways. No one works so far.
One of
the approaches I tried is to have the a PlanForm and a
ContributorForm. And one of the properties/fields in PlanForm is
ContributorForm[]. I think it is a way to do it. But I don't know
how.
Can
someone point me to some solution. I really
appreciate.

Why
should not the reset() be used? Isn't it called automatically,
anyways? Such as when the validation of the form
fails?

(1) Have a Vector / Collection of contributors
(ie. getContributors()) belonging to your form. Inside that function,
check to see if you need more rows by using code similar to the
following:
public Vector
getCustomerContacts()
{ CustomerContact
lastCustomerContact =
(CustomerContact)this.customerContacts.lastElement();
if (!lastCustomerContact.isEmpty())
// is this slot being
used?
this.customerContacts.addElement(new CustomerContact());
// always have one available slot at the end of the
matrix
return this.customerContacts; }
(2) Do not use the reset() method.
(3) On your JSP, use code like
this:
<% int i = 0;
%>
<% i++;
%>
(4) Have a button on the form "Add more rows"
in which case the form posts to itself and will cause a new row to be added
at the bottom of the grid.
Hope this help,
Jeff

Subject: Question on the ActionForm
design for dynamic data?
Here is the situation.
I am developing a system to maintain a
contribution plan. I need to input the plan information first and
add unlimited number of contributors, specifying each share of the
plan. So there will be a page with contribution plan information and
a list of all the contributors. The information you can edit on this
page is the percentage of share of each contributor. Validation rules are:
share need to add up to 100 and share figure is an integer between 0 and
100. Since the number of contributors is unknown in advance,
how should I design the ActionForm?
Thanks a lot,

Radio Buttons With Generated Values
HI! I am pretty new to struts and I'm working my way through the different types of controls (select, multiboxes, etc). I am having rouble generating a list of radio buttons. I have a Map (actual a Properties object but its returned as a Map) which contains two entries: "DEBIT", "Debit my credit card" "INVOICE", "Send me an invoice". The Map object is available in my JSP page as the bean paymentTypeData: It is also accessable via another bean paymentData using the getter method getPaymentType(): I am trying to generate the following HTML: Debit my credit card Send me an invoice The closest I can get is (some spacing removed) INVOICE Debit my credit card DEBIT Send me an invoice by using the following JSP: I've had to put the 'value="fred"' in there, as value is required. Removing it gives "required attribute `value' missing from `html:radio' " Any suggestions about how I set dynamic values for "value"?

Title: RE: Access to form data.
Martin,
I have a similar problem too.
May I ask two general questions?
1.When should I use the formBean attribute on the tag?
2. What is the relationship among ActionForm, actionformbean and actionformbeans.
I tried to find the answer myself, but couldn't. Thanks a lot, and sorry for the dummy questions.

Subject: e: Access to form data.
When you use the formBean attribute on the tag, you are
defining a bean which corresponds to the ActionFormBean instance for your
form bean definition (i.e. the entry) in struts-config.xml. You
are not defining a bean corresponding to your ActionForm bean itself.
If your form bean exists in some scope already (i.e. either Struts put it
there when processing a request or you put it there when processing an
action), then all you need is:
where "yourFormBeanName" is the name of the attribute used to store the
bean. If Struts created the form bean for you, the attribute name is the
name you specified in the entry in your struts-config.xml file.
Hope this helps.

If you are forwarding the set as part of the ActionForm, Struts may have
recycled it and called reset().
You might need to do something like,
request.setAttribute("searchResult",searchForm);
before returning, and then check for searchResult in your JSP.

Resin's XSL tranformations not possible?
I was trying to use Resin's XTP capability (JSP pages initially tranformed with XSL stylesheets) with Struts. I started with converting struts-example web-app's registration.jsp. I simply added the following declarations at the top of the file: and slightly reformatted the file to make it well-formed xml. I also changed file's extension to .xtp (making appropriate changes to struts-config.xml) so the file is mapped to Resin's XtpServlet instead of JspServlet. When I try to browse the file, I get the following exception: /struts-example/registration.xtp:175: expected at com.caucho.jsp.JspParseException: /struts-example/registration.xtp:175: expected at at com.caucho.jsp.JspParser.error(JspParser.java:1063) at com.caucho.jsp.JspParser.parseCloseTag(JspParser.java:929) at com.caucho.jsp.JspParser.parseNode(JspParser.java:324) at com.caucho.jsp.JspParser.parseJsp(JspParser.java:286) at com.caucho.jsp.JspParser.parse(JspParser.java:185) at com.caucho.jsp.JspParser.parse(JspParser.java:159) at com.caucho.jsp.XtpPage.getJspPage(XtpPage.java:532) at com.caucho.jsp.XtpPage.compileJspPage(XtpPage.java:375) at com.caucho.jsp.XtpPage.subservice(XtpPage.java:220) at com.caucho.jsp.Page.service(Page.java:407) at com.caucho.server.http.Invocation.service(Invocation.java:285) at com.caucho.server.http.QRequestDispatcher.forward(QRequestDisp atcher.java:157) at com.caucho.server.http.QRequestDispatcher.forward(QRequestDisp atcher.java:76) at org.apache.struts.action.ActionServlet.processActionForward(Actio nServlet.java:1747) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1 584) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:490 ) at javax.servlet.http.HttpServlet.service(HttpServlet.java:102) at javax.servlet.http.HttpServlet.service(HttpServlet.java:83) at com.caucho.server.http.Invocation.service(Invocation.java:291) at com.caucho.server.http.RunnerRequest.handleRequest(RunnerReq uest.java:333) at com.caucho.server.http.RunnerRequest.handleConnection(RunnerR equest.java:266) at com.caucho.server.TcpConnection.run(TcpConnection.java:140) at java.lang.Thread.run(Thread.java:479) Has anyone used Struts with Resin's XTP? -- úukasz Kowalczyk
