Here ist the Code I wrote:
FormBean:

private FormBeanVector timeProofList = new
FormBeanVector(TimeProofTableBean.class);
private FormBeanVector dayBeanList = new FormBeanVector(DayBean.class);
}
***************************************************************************
My own vector:
public class FormBeanVector extends Vector {
// Empty constructor, just to set the type of class
public FormBeanVector( Class _contentClass ) {

_contentClass.getName());
this.contentClass = _contentClass;

}
// Constructor for the java.util.vector type
public FormBeanVector( Class _contentClass, java.util.Vector vector ) {
// Call my own constructor
this( _contentClass );

}
}
// Call set from java.util.vector to set the element
return super.set( index, value );

an example jsp code:
<logic:iterate id="dayBeanList" indexId="listIdx" name="timeProofForm" prope
rty="dayBeanList">

can you find the error I get?

Subject: RE: beanutils populate problem with formbeans and vectors
Michael,
The problem is that the get method is being called when your Collection is
empty. This is causing the ArrayIndexOutOfBounds exception that you are
seeing. What I have done to prevent this problem is to code my getXXXXX(int
index) and setXXXX(int index, Object obj) methods like this:
public Object getMyVector(int index) {
if (index >= myVector.size())
return "";
return myVector.get(index);
}
public void setMyVector(int index, Object value) {
int size=myVector.size();
if (index >= size) {
for(int i=size; i<=index; i++) {
myVector.add("");
}
}
myVector.set(index,value);
}
For the get method, I just return an empty string if the index is bigger
than the current size of the vector. For the set method, I increase the size
of the vector up to the index if the current size is smaller, otherwise I
just set the value that the index points to. This alleviates the need to
pre-fill the Vector in the constructor.
This solution also works with indexed properties in an html form too.
Regards,
Richard
