RE: what setters do i implement in an indexed tag--NewBie question
John
Made few changes and code worked fine.
Would like to extend this so that it will work for handling Dynamic
table situation-- Let me explain
If u see in Action form reset method I initialized it to 5 (num="5 "for
testing) so the page loads with five empty rows, But we have a
requirement where the user can add more rows to the table and click
submit.
1. Action form code:
private ArrayList personList;
public void reset(ActionMapping mapping, HttpServletRequest request){
this.personList = new ArrayList();
// String num = request.getParameter("personListLength");
String num ="5";
try {
if (num != null) {
int len = Integer.parseInt(num);
for (int i = 0; i < len; i++)
this.personList.add(new PersonBean());
}
}catch (NumberFormatException e) {
e.printStackTrace();
}
}
public PersonBean getPerson(int ndx) {
return (PersonBean) personList.get(ndx);
}
public void setPersonList(int ndx, PersonBean p) {
personList.set(ndx, p);
}
public ArrayList getPersonList(){
return this.personList;
}
2. jsp
3.PersonBean:
public class PersonBean implements Serializable
{
String firstName;
String phoneNo;
public PersonBean()
{
super();
}
public String getFirstName()
{
return firstName;
}
public void setFirstName(String newFirstName)
{
firstName = newFirstName;
}
public String getPhoneNo()
{
return phoneNo;
}
public void setPhoneNo(String newPhoneNo)
{
phoneNo = newPhoneNo;
}
}
Let me know if u need any further info.
Thanks

Sashi, your person bean must have getName(), setName() and getPhoneNo(),
setPhoneNo().
Everybody: I haven't come across the html:taglib indexed property
before. This seems to do what nested: tags do - is this functional
overlap?
Generally with JST taglib as well, there seems to be a wide choice of
taglibs to use - is this going to consolidate at some point in struts'
development?

Forgot to mention, I believe for the case of indexing using
logic:iterate your id must match your property. So in your example set
id="personList"
Now if you switch over to nested:iterate, the whole id thing goes away
and the property and type attributes are sufficient.

RE: what setters do i implement in an indexed tag ?
I'm following closely Dave's example code and almost have it working, except
that on post of the JSP form the parameter's values (which are correct) are
not stored in the Formbean's list. So seem to have had the same problem and
solved it. However, I fail to see what the difference between your 'hacked'
version and Dave's original code is. Please enlighten me.

RE: what setters do i implement in an indexed tag ?
Here is a hacked version of the code posted by David Hay previously. The
code here will compile and run - a Vector is populated then displayed.
After a post, the vector is retrieved from the form and then System.out is
used to show its size.
This should help others that are having problems with indexed tags. You'll
need to point your browser to somthing that looks like
http://localhost/struts/ShowParameters.do once you've copied all the files
into the correct locations.
There were two issues with the way i was trying to do it, firstly it seems that unless
the scope of the form is set to session (or not specified) it doesn't work and
secondly because i was using a different id for the name in the logic:iterate /
html:text tags (when i set them to
"parameter" it worked).

Re: what setters do i implement in an indexed tag ?
Hal,
Thanks, your post is what I needed.
However, I believe there is a bug in your post. In the following code
snippet:
if (index > interestRates.size()-1)
{
interestRates.add(index,new InterestRateJBean());
}
using the add to insert a "slot" at an indexed location may cause other
locations in the ArrayList to be shifted over. This may be a problem since
there is no guarantee that the indexed properties are processed in order --
I found that some of my attributes became scrambled e.g., attribute for row
2 updated in row 1.
I replaced this code with the code below and everything appeared to work
correctly.:
int count = Index - this.interestRates.size() + 1;
for (int i = 0; i < count; i++) {
this.interestRates.add(new InterestRateJBean());
}
Basically, if I get an index of 5 then I make sure there are 6 (5 + 1) slots
in the ArrayList.
Hope this helps.
Stephen

| In the indexed tags write up at

the

|
| public void setParameter(int index, Parameter p){...};
|
| In your case that means:
|
| public void setParameter(int index, FieldMapping f) {...};
|
| You probably don't need:
| public void setFieldMappings(java.util.Vector newFieldMappings) {
| fieldMappings = newFieldMappings;
| }
| unless you use it in your action to populate the form object before

Hi,
You need 3 methods, a getter and a setter for the Vector (or other
arraytype object) and a getter for single object in your arraytype
object, i.e., getObject(int inx){ return myVector.elementAt(inx) }
Just like on the webpage mentioned.
the setters needed should be defined on the object your are returning
in the getObject method. That is, what happens when the form fild data
is passed to the form object is:
getObject(inx).setProperty(someProperty).

In the indexed tags write up at
http://www.husted.com/about/struts/indexed-tags.htm, it only mentions the
two types of get methods required in the action form. It doesn't mention the
setters that are required. It looks like the getParameterList() method is
only used by the iterate tag. To populate the form on submit the only setter
needed is:
public void setParameter(int index, Parameter p){...};
In your case that means:
public void setParameter(int index, FieldMapping f) {...};
You probably don't need:
public void setFieldMappings(java.util.Vector newFieldMappings) {
fieldMappings = newFieldMappings;
}
unless you use it in your action to populate the form object before
displaying the form jsp.
I am about to try this myself so this is just a guess.

Subject: what setters do i implement in an indexed tag ?
I've created a page using indexed tags (neat stuff!).
Here is what is currently working for me:
o If i populate the form's vector, values from that vector are displayed in
the jsp
Here is what it not working:
o when the form is posted back, the vector is null (in the struts perform()
method)
I suspect i haven't implemented some sort of setter within the form but i
can't find an example as to what method should be implemented. I've tried
ArrayList and using parameterList instead with no different result.
Thanks,
Waz.

RE: what setters do i implement in an indexed tag ?
Hi,
You need 3 methods, a getter and a setter for the Vector (or other
arraytype object) and a getter for single object in your arraytype
object, i.e., getObject(int inx){ return myVector.elementAt(inx) }
Just like on the webpage mentioned.
the setters needed should be defined on the object your are returning
in the getObject method. That is, what happens when the form fild data
is passed to the form object is:
getObject(inx).setProperty(someProperty).

RE: what setters do i implement in an indexed tag ?
Ignore my previous post because I was mistaken. You don't need a setXYZ(int
index, XYZ x) method because struts will call the "public XYZ getXYZ(index
i)" method and then call the appropriate set method on the bean that is
returned. This worked for me (with last nights CVS):
/td>
which generates field names like "interestRate[0].monthId"
so struts will call form.getInterestRate(0).setMonthId(somevalue)
I had this in my form class:
ArrayList interestRates; // initialized in constructor and reset()
public InterestRateJBean getInterestRate(int index)
{
if (index > interestRates.size()-1)
{
interestRates.add(index,new InterestRateJBean());
}
return (InterestRateJBean) interestRates.get(index);
}
Again, I just got this to work so I may be missing something.
