I'm also having trouble concerning indexed properties with BeanUtils. If
the type of the indexed property is String, then BeanUtils.populate throws
IllegalArgumentException.
Using your NameBean in an example:
...
NameBean nameBean = new NameBean();
BeanUtils.populate(nameBean,new String[] {"John", "Paul", "Jack"});
// above throws IllegalArgumentException!
...
If I take the same indexed property and change it to an int
BeanUtils.populate works!
I've posted this problem to both the jakarta-commons-dev and struts-user
lists with no response. So I don't know if it is supported or not. Please,
can someone give us an answer???

Subject: BeanUtils
Do BeanUtils.describe and BeanUtils.populate supposed to handle indexed
properties?
Suppose I have this JavaBean:
public class NameBean {
private String[] name;
public String[] getName() {
return this.name;
}
public void setName(String[] name) {
this.name = name;
}
public String getName(int index) {
return this.name[index];
}
public void setName(int index, String name) {
this.name[index] = name;
}
}
I would expect the following code to return a Map containing:
name[0]="John", name[1]="Paul", name[2]="Jack"
but instead, I get name="John".
Only the first element is considered.
...
NameBean nameBean = new NameBean();
nameBean.setName(new String[] {"John", "Paul", "Jack"});
Map properties = BeanUtils.describe(nameBean);
...
