Hi, how to work with nested objects using form directive? I need to bind an entire object to form object and validate it with all nested objects. Do nested objects have to be FormProxyObject too? I'm also using Hibernate.

<div viewModel="@id('vm') @init('com.person.PersonVM')" validationMessages="@id('vmsgs')">

    <div class="content" form="@id('fx') @load(vm.person) @save(vm.person,before='save') @validator('vm.FormValidator')">

        <label sclass="subtitle is-4" value="Edit Person"/>

        <separator />

        <div class="field">
            <label sclass="label"  value="Name" />
            <div class="control">
                <textbox class="input" value="@bind(fx.name)" />
                <label sclass="help is-danger" value="@load(vmsgs['name'])"/>
            </div>
        </div>

        <div class="field">
            <label sclass="label"  value="Age" />
            <div class="control">
                <intbox class="input" value="@bind(fx.age)"/>
                <label sclass="help is-danger" value="@load(vmsgs['age'])"/>
            </div>
        </div>

        <div class="field">
            <label sclass="label"  value="Street Name" />
            <div class="control">
                <textbox class="input" value="@bind(fx.address.streetName)" />
                <label sclass="help is-danger" value="@load(vmsgs['streetName'])"/>
            </div>
        </div>

        <div class="field">
            <label sclass="label"  value="Number" />
            <div class="control">
                <intbox class="input" value="@bind(fx.address.number)" />
                <label sclass="help is-danger" value="@load(vmsgs['number'])"/>
                <label sclass="help is-danger" value="@load(vmsgs['numberValid'])"/>
            </div>
        </div>

    <button label="Save" onClick="@command('save')"/>

    </div>
</div>

Your code looks correct, the form binding will automatically create a proxy around the nested person.address object if possible so you can validate the streetName before saving it.

Did you encounter any problem there? Did something not work as expected?
