When I develop content page inheritance, I didn't get values of multifield (save by nodes).
The InheritanceValueMap only get component data (title field), doesn't get child nodes data (items node).
Any suggestions or ideas on this?
Thanks,
Canh Nguyen,
How are you trying to read items0, item1, etc

If I don't get inheritance properties, I use @ChildResource(name = "items").
When I get inherit properties, I think 'items' properties like JSON array and include in 'listoflinks' node.
I think I need to custom multifield save by JSON array.

Have you tried to code that?

Yep, I try to code that.
I have a problem when I get inheritance properties of multifield.
InheritanceValueMap doesn't get parent multifield property.

The inheritanceValueMap is just looking up the hierachy, it is not taking child nodes of ancestors into consideration.

My approach is I get component resource by resourceType after I get InheritanceValueMap of the component. I have a problem when I get InheritanceValueMap, I don't get child node properties.
I think if multifield save by JSON array, I can get the inheritance of multifield properties.

Look at Joergs response. If you want to read child nodes - look at using the JCR API to read them.
