Re: [Hawkular-dev] Inventory - /entity/{path}/treeHash - Cannot cast BaseEnvironments$Single to Synced$Single
It's a poorly handled error condition.
Not all entity types support tree hashes. Only those tha can be synced also
have a tree hash (because tree hash is used to minimize the number of updates
we need to do).
You can only sync a feed and anything underneath it - resources, metrics,
resource types, metric types, operation types and data.
Environments are not syncable (at least now) and so you cannot obtain a
treeHash of them.
That said, you should get a more comprehensible error message than the above.
Would you mind creating an issue for that at

Hope this helps,

I am using the inventory "entity" API - Day1 of using it,

silly mistake.
Using services v0.0.12.Final which has v0.18.0Final of inventory.
I am able to create and get an entity, but when i try to get the treeHash,
i get a cast exception.
