Auto-grow binding

[Tobia]

Hello,
i have a simple bean like this:

class Test{

private String field1

private String field2

private String field3

}

and a Command

class Command{

private String username

private String password

private Test composite

}

Can I auto-bind that object with a composite-path? like this:

<form:input path="username" />
<form:input path="password" />
<form:input path="composite.field1" />
<form:input path="composite.field2" />
<form:input path="composite.field3" />

I tried like before, but I get this error:
auto-grow nested property path: java.lang.InstantiationException

Your form code looks ok, but your bean and command class both are called "Test". Is this right? I'm asking because for me the composite property is a command object.

Otherwise it is difficult to say what is wrong here. Could you post some more details?

I found, the Test object was not initiate by the Command constructor... i'm sorry
