Re: Unexpected results using Block Join Parent Query Parser

[Jan Høydahl]

I guess the key question here is whether «parent» in BlockJoin is strictly 
top-level parent/root, i.e. class:composition for the example in this tread? Or 
can {!parent} parser also be used to select the «child» level in a 
child/grandchild relationship inside a block?
