Binding collections to Spring form

[Vyas Sanzgiri]

I am trying to bind a collection of values to Spring form but I get the following error. I tried to do it with LazyList but still the same issue. Any pointer to the correct article which can help me get started?

javax.servlet.ServletException: org.springframework.beans.InvalidPropertyException : Invalid property 'parameters[0]' of bean class [beans.Input]: Index of out of bounds in property path 'parameters[0]'; nested exception is java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

The list must have at least one data (index 0).

It has information but the binding is not working. List has more than 1 element in my test case

[Hong Anderson]

You should try to debug then, it tried to access something that has no data in list.

I understand that !! but I am not able to figure out. I tried to debug but I do not want to go under the covers into Spring framework.

When you debug, you're supposed to debug in Spring Framework code to see what actually happens.

I do not want to debug the Spring framework code. I would rather concentrate on my business logic

You're not debugging Spring framework code - it's not just magically losing values - you're debugging how *you're* using Spring framework code.
