Problems with multiple Beaneditors inside Component

Hi guys,

i have some serious trouble with a custom component.
The component needs to have multiple zones and beaneditors nested and thats the problem.
I can’t get it to work. I’ve tried some variants, without success.

(using 5.4-Beta6)

Where is my mistake? Any clues?

PAGE:
<t:zone t:id="rootZone">
<t:form t:id="rootForm" t:zone="^">
<t:beaneditor t:id=„rootFormBeaneditor“ object=„MyCustomObject"></t:beaneditor>
</t:form>
</t:zone>

COMPONENT - Variant A:
Page renders fine, when updating ChildZone A (returning zoneA.getBody() via eventhandler):
TapestryException: No object of type org.apache.tapestry5.services.FormSupport is available from the Environment

<t:zone t:id="childZone_A">
< t:beaneditor t:id="childForm_A"></t:beaneditor>
</t:zone>

<t:zone t:id="childZone_B">
<t:loop formState="ITERATION">
< t:beaneditor t:id="childForm_B"></t:beaneditor>
</t:loop>
</t:zone>

COMPONENT - Variant B:
Page renders fine, when updating ChildZone B (returning zoneB.getBody() via eventhandler):
TapestryException: No object of type org.apache.tapestry5.services.FormSupport is available from the Environment
<t:zone t:id="childZone_A">
<t:beaneditform t:id="childForm_A"></t:beaneditform>
</t:zone>

<t:zone t:id="childZone_B">
<t:loop formState="ITERATION">
<t:beaneditor t:id="childForm_B"></t:beaneditor>
</t:loop>
</t:zone>

COMPONENT - Variant C:
Page renders fine, updating ChildZone B works, but when reloading the whole page:
TapestryException: Form components may not be placed inside other Form components.
<t:zone t:id="childZone_A">
<t:beaneditform t:id="childForm_A"></t:beaneditform>
</t:zone>

<t:zone t:id="childZone_B">
<t:loop formState="ITERATION">
<t:beaneditform t:id="childForm_B"></t:beaneditform>
</t:loop>
</t:zone>

Best regards,
Stefan
