Question

I’m trying to do a CRUD for my bean in Spring MVC and i found it to be a bit overwhelming.

thing is, that one of bean element is ArrayList of another class

its looks like

class Bean{
...
    String componentName;
    ArrayList<InnerComponent> component;
...
}

With getters and setters ofc
and InnerComponent is pritty simple, its like

class InnerComponent{
String key;
String va;
}

now Question: How can i create form, that allows to input something in that array list?

<form:form commandName="Bean" id="Bean" action="#">
    <form:input type="text" path="componentName" /><br />
    ....??
    <form:button>Submit</form:button>
</form:form>

Can figure this out…
