Will be scanning the class hierarchy with a filter on the @class field? Or will the same behavior as for clusters?
I'll try to suggest the following approach: select from cluster:some_cluster - selected data from cluster (so works now) select from class:some_class - selected data from class (all clusters for class) without class hierarchy select from some_class - selected data from class hierarchy (so works now) On Wednesday, June 18, 2014 5:22:10 PM UTC+3, Andrey Lomakin wrote: > > Oh I see Dmitriy I am sorry, > Could you try @class = 'BaseClass' as condition ? > > > On Wed, Jun 18, 2014 at 4:22 PM, Dmitry <[email protected] <javascript:>> > wrote: > >> Hmm... >> >> From docs: "Used to check if the record extends a class" >> I understand that: MyAccount instanceof BaseAccount is true.
