Hello,

I'm new to OrientDB. 
I have a simple OrientDB database with Classes and one type of relationship 
between them. 
Even if is one type of Edge we decided to use a 'type' attribute for the 
Edge that differentiates between them.

Class0 --has a--> Class1
Class1 --has a--> Class2
Class1 --is a--> Class3


I'm interested to start traversing the graph from Class0 vertex (with id 
#12:7), but only following the relations that have the 'type' attribute 
'has a'.
So the result should be Class0, Class1, Class2

I'm not managing to find a correct 'while' clause...

Something like this is obviously not ok
traverse outE(), out() from #12:7 while (@class = 'Class' or (@class = 
'Relation' and outE().type = 'has a'))

Any hints for me pls?
Thank you!
